I’m looking to source it. I’ll let you know how it goes…
Since this is a safe place… what about RAD-140?
I’ve never used RAD 140 but SARMs are a load of shit. They got people all excited in the beginning because it was claimed they didn’t affect your HPTA, but it was sadly all too good to be true and they do in fact suppress your natural hormones.
AAS, fat burners, GH and MK677 are the only things worth fucking about with. SARMs and peptides aren’t worth your time.

I have had 2 compliments on my physique this week at work. The first was that I had an ass like J-Lo (which came from the hottest chick at my work by far so pretty happy with that) the second, and my personal favourite, is that I’m like a “hench Shaggy from Scooby Do.”
Not even 100% sure the second one was meant as a compliment but I’m delighted with it anyway.

Would she be hot outside of work? …or is she just ‘work’ hot, because you see her every day?
I’ve had to have friends set me straight because I started to fall for ‘work’ hot while in college.
oh my god no she’s one of the hottest chicks I’ve ever seen in my life. She actually said to me once that she and I could do the friends with benefits thing if she breaks up with her boyfriend, and apparently they’ve not been getting along lately so fingers crossed on that.
“Work hot” is totally a thing though. When you start in an office where there’s no one good you’re like “god damn not a single honey in here” but after a while you start checking out the best of a bad bunch like “yeah I’d wreck that…”

You don’t strike me as the type to wait around for the inevitable break up. You gotta move, the J-Lo comment shows she is ready. You work at a hotel, no? …dude, perfect for FWB!
I’m embarrassed to say I was so close to falling for it. My buddy saved me while we were all at the bar one night.
obviously I suggested that we didn’t need to wait, but she rejected that idea. It was worth a try!
Have fallen for it several times. My mates don’t have my back the way yours do.

What fat burner would you say has good results and is “safe”?
Would you take DNP? I am amazed at the amount of people on that on reddit.
I don’t think any of them are safe, to be honest. I get great results from clen but from the way it makes me feel when I’m on it you can just tell it’s poison. I can just about manage 5 days on it before I can’t take anymore. I’ve never used T3 but probably will in future.
I would definitely use DNP. I’ve heard of guys losing 10lbs of fat in a week. It’s serious shit though so I’d never go above 250mg a day (which is, to my knowledge, the minimum dose the caps come in).
I don’t have a source for it though, which is probably for the best.
Do you take Ketotifen with Clen?
Never; I think it’s a fucking stupid idea.
Clen is really bad for you, so, instead of trying to find ways to stay on it as long as possible, use the minimum effective dose for the minimum length of time.
I’ve got a fucking brilliant write up on clen saved somewhere. Give me a minute and I’ll see if I can dig it up.

First ‘The Man’ marginalized ephedra. Then we saw the realization of a second supplement ban—one which will effectively deprive the mainstream bodybuilding community of its most-preferred anti-catabolic ancillary: the pro-hormone or pro-steroid. So just how the hell is a dieter supposed to preserve lean body mass these days while languishing on laughably low calories? Well, aside from investing in our beloved LeptiGen and shipping out for real gear, it seems like a lot of would-be-chiseled chaps are taking a new interest in the age-old diet drug Clenbuterol (1-(4-Amino-3,5-dichlorophenyl)-2-tert-butyl-aminoethanol), a sympathomimetic beta2 adrenergic agonist most commonly used in veterinary therapeutics and livestock doping. But is this recent, glaringly rekindled curiosity in clen leading would-be and first-time users to the right drug? Or for that matter, is clen a safe drug? So, without further ado, I think it’s time M&M gave ephedra’s “wonder-cuz’” its full-on, discerning attention.
Clen in Context: Basic Pharmacology
I throw around the word sympathomimetic a lot to compensate for my chronically low self-esteem. In the forums, in my sleep, during sex—it’s just such a dazzlingly erudite sounding word. And using it makes me feel special. And while you yourself may not feel the inclination to use it colloquially any time soon, if phrases like “nutrient partitioning” or “fat loss while preserving muscle” pique your interest, you should care about how this class of compounds works and what those workings result in.
Chances are you wouldn’t be reading this article if you didn’t, so quickly: sympathomimetics (take “sympath” from ‘sympathetic nervous system,’ throw an ‘o’ on there, and add ‘mimetic’ [i.e. ‘to mimic’] and you’re in business) are a class of drugs that affect the sympathetic nervous system (SNS), either by prompting central catecholamine (NE/NA and E/A) release or by peripherally mimicking the effects of those same endogenous hormone/neurotransmitters. Most of a sympathomimetic’s pharmalogical interplay occurs via interaction with beta andrenoreceptors. Ephedrine is a sympathomimetic, norephedrine is a sympathomimetic, H.E.A.T. is a sympathomimetic, and boy is clenbuterol ever a sympathomimetic. There are also many others.
With clenbuterol specifically, what we see is both forms of sympathomimetic activity. Clen synthetic mimics some of norepinephrine’s and epinephrine’s effects in specific outreaches of the SNS, and centrally exerts these effects in skeletal muscle, adipose tissue, and in an often-overlooked third area: the brain. Yes, that’s right: clenbuterol crosses the blood brain barrier, and is able to readily activate certain central adrenoreceptors (1).
Virtually all of this peripheral mimicking occurs at the beta2 adrenergic receptor, which is the reason clenbuterol is characterized as a beta2 specific agonist. When it interacts with these receptors in muscle, clenbuterol is able to catalyze Cyclic Adenosine Monophosphate (cAMP) production, a second-messenger signal transducer which regulates rates of glycogen decomposition, protein synthesis, and lipolysis (among many other things). What distinguishes clenbuterol prominently from ephedrine is its specificity, potency, and duration of effect.
Ephedrine, whether you already knew it or not, has very little direct activity in muscle or fat. Rather, it stimulates central sympathetic nerve terminals, thereby inciting an indiscriminate release of NE/NA (and to a lesser extent, epinephrine/adrenalin), which then relays across the entirety of the SNS. This makes ephedrine a primarily indirect and non-specific sympathomimetic, as it effectively delivers a mild ‘catecholamine carpet-bombing’ to all your various beta receptors (beta1, beta2, atypical beta3, and putative, atypical beta4). It is also this mechanism that gives ephedrine its long-term pharmacological viability: although not very set-point friendly, it will nonetheless continue to indirectly agonize adrenergic receptors along your SNS, even after months of continual use.
Clenbuterol is somewhat of a different beast. As mentioned earlier, it is able to prompt a small degree of catecholamine release from central adrenoceptors, as well as interact directly with the beta2 receptor in a dose-dependent manner with a potency that far exceeds the resultant effects of ephedrine administration.
More Technical Stuff on Clen’s Workings than You Could Ever Possibly Want to Know: Lipolysis
Nutrient-partitioning junkies, your patience is about to be rewarded. Now that we’ve established some context, it’s time to move on and discuss ‘the goods.’ It’s time to discuss the bad-ass lipolytic and repartitioning effects of clenbuterol in vivo. And it goes a little something like this. Following administration, clenbuterol avoids first-pass metabolism (it’s oral bioavailability ranges between 89-98%) and doses typically reach peak plasma levels roughly two hours after a dosage is ingested. This peak will then stabilize and continue for four additional hours (2). Eventually, roughly 50% of ingested clenbuterol will undergo metabolization into its four primary metabolites; the remaining half will be excreted intact, without metabolic breakdown (3). This biphasic elimination lends clenbuterol a veritable half-life that clocks in at just under thirty six hours.
Once it gets to work clenbuterol, as I already mentioned, binds to cellular beta2 receptors. Intracellularly this will increase cAMP (4), which then binds to regulatory subunits of protein kinase A, causing the release of its catalytic subunit. This process activates the enzyme HSL (hormone sensitive lipase), which hydrolyzes triglycerides, breaking them down into glycerol and fatty acids to allow for beta oxidation.
Now, as you can probably guess, one of the facets to clenbuterol that makes it such a potent lipolytic drug is that it exerts its beta-agonism steadily and continuously. If ephedrine is ‘hit-it-and-quit-it,’ clenbuterol is a friggin’ marathon man when it comes to stimulation. Clen isn’t very cuddly though, so all you high-maintenance bodybuilders are just plum out of luck.
Clenbuterol is undeniably potent at its target receptor. However, clenbuterol cannot be said to own ephedrine (particularly when combined with caffeine) outright for fat loss. Remember, since clen is primarily direct-acting on a cellular level, it can’t prompt the same kind of NE-induced hypophagia (loss of appetite) as ephedrine, which has proved to be an essential pharmacological component in its ability to further weight loss (5). Individuals looking to use clenbuterol for weight loss need to keep this in mind: clenbuterol partitions energy intake, but it will not aide in regulating or helping to decrease it, hence my recommendation that those planning to cut on clen also look into ancillary appetite suppressants.
There is also the prevailing theory in a lot of bodybuilding circles that clenbuterol actually raises metabolic rate by increasing endogenous thermogenesis. So let’s explore the purported calorie-burning properties of clenbuterol. In animals, although clenbuterol increases thermogenesis in mutant rats (genetically obese Zucker rats), multiple studies have demonstrated that in normal rats—even those administered rather hefty dosages of the drug— clenbuterol “did not affect energy intake [or] energy expenditure” (6,7).
In human studies, the direct infusion of the related beta2-specific agonists salbutamol and terbutaline in lean men caused a modest increase in whole body energy expenditure and respiratory exchange ratio—an increase of 0.6 kJ/min in terms EE adjusted for fat-free mass (8). In other words, the guys getting heavy-duty beta2 adrenergic stimulation would have ended up burning about 200 extra kcals over a twenty four hour period. So in other words, thermogenesis was enhanced, but not so much to suggest that clenbuterol has strong calorie-burning properties of its own. Interestingly enough, in the same study the researchers noted that:
during beta2-adrenergic stimulation, the increases in energy expenditure and plasma nonesterified fatty acids and glycerol concentrations were reduced in the obese group. Furthermore, lipid oxidation significantly increased in the normal weight group, but remained similar in the overweight group… [this] data suggests that beta2-adrenoceptor-mediated increases in thermogenesis and lipid utilization are impaired in the obese (8).
In other words, if you’re still in plus-size pants, you’re out of luck: clenbuterol isn’t going to help you lose a whole lot of weight, because your obesity-train-wrecked metabolism just ain’t havin’ that (9). Plus, given the effects of beta adrenergic agonists on heart rate contraction, the use of clenbuterol in significantly overweight individuals may pose significant danger to the user (10,11).
And again, the take home message is the same: when dieting, nutrient-partitioning definitely matters, but in the end it still comes down largely to energy expenditure vs. intake, and clen is a calorie re-distributor, not a burner.
Clenbuterol and its Interaction(s) With Your Mammoth Guns
If you get one sentence out of this section on clenbuterol and skeletal muscle, please let it be this: clen is never going to get you big, but it is extremely good at keeping you big once you get there. Yes, I know clenbuterol is wicked-anabolic in Dawley-Sprague hyperphagic wombats, but you are a human, and the amount of clenbuterol it would take for you to see a genuine anabolic effect would also put you in a coffin, so let’s just let that one go.
Now, I said clen’s not anabolic, but it certainly does have positive ramifications for protein synthesis, primarily through the beta2s, cAMP, and its ability to mitigate Ca2±dependent proteolysis in skeletal muscle (12). A critical component to its full effect is its repartitioning properties. As stated earlier, clenbuterol is exceedingly good at liberating fatty acids from adipose tissue. But, more than that, clenbuterol exerts this effect in tandem with large scale, itself-induced skeletal muscular insulin resistance (13).
Now, when you’re a type II diabetic, this isn’t so hot. However, in a healthy bodybuilder using a strong sympathomimetic you basically have the best of all worlds: plenty of free-fatty acids getting released for oxidation in muscle, plenty of insulin-resistant muscle to feast on them, and pretty much all consumed calories getting spared for muscle retention and protein synthesis. Granted, there’s very little good research on human skeletal muscle in the presence of clenbuterol (particularly when it comes to athletes), but reasoned inference and extrapolation certainly paints a pretty convincing picture that clenbuterol is significantly anti-catabolic.
For starters, human research with ephedrine and caffeine has demonstrated that indiscriminate, weaker beta-adrenergic agonism significantly improves protein deposition and preserves lean body mass during periods of caloric restriction (14). Also interesting was the researchers’ discovery that the ephedrine and caffeine mixture wasn’t attenuating skeletal muscular breakdown, but was in fact accelerating protein synthesis. This was proved clinically by 3-methylhistidine examination, an index for skeletal muscle breakdown.
In the sympathomimetic group, an increase in nitrogen balance was demonstrated independent of 3-methylhistidine, which means the ephedrine was actually helping to synthesize lean tissue at a faster rate, and thereby counteracting the increase in diet-induced catabolism (15). See? I wasn’t lying when I said clenbuterol could be anabolic; you just can’t take a high enough dose to get an anabolic degree of protein synthesis augmentation without ending up in the ER long before you could get your shaky ass anywhere near a squat rack.
Nonetheless, because of its pharmacology, clenbuterol is currently recognized in the scientific community as a valid remedial treatment for muscle-wasting conditions (16,17). In rodents, clenbuterol also actively inhibits glucocorticoid-induced muscle atrophy, and one can speculate that it may also exert similar anti-glucocorticoid properties in humans as well (18). Clenbuterol, by virtue of its beta-agonism, may also even be more effective at reducing glucocorticoid activity than that though, as it has been demonstrated that beta-receptor antagonism increases the release of adrenocorticotrophin (ACTH) in humans subjected to stress (19). For those unaware, ACTH is a pituitary hormone that stimulates cortisol secretion, which means there is a possibility that beta-receptor agonism may in fact be able to prompt the opposite: a decrease in ACTH release in response to stress.
All told, clenbuterol is pretty much the bomb and the shiznit as far drugs go for preserving muscle during periods of energy restriction through a number of different pathways. Oh but there are just a few more things…
But I’m Too Sexy To Die… (Side Effects and Precautions Pt. I)
By now it should be clear that clenbuterol is a powerful drug. And with all powerful drugs, there are consequences, ‘cause life just sucks like that. So for those of you about to get all ‘clenbutaholic’ with your research chemicals, here’s a little info I counsel you to take to heart. In fact, speaking of hearts, let’s examine yours in relation to clenbuterol, because there definitely is some cause for concern.
For starters, there are more rodent studies under the sun that show clenbuterol use can cause significant cardiac hypertrophy—so many in fact that I’m not even going to bother citing them. Just type “clenbuterol” and “cardiac hypertrophy” into Google if you don’t believe me; no lie, it’s a little unsettling. However, clenbuterol also kills fat cells (adipocyte apoptosis) in rodents too, and it sure doesn’t in humans, so take that animal data for what it’s worth. Unfortunately though, things don’t look too much better when we move up the evolutionary chain and start looking at hearts in good-ole’ human beings either.
For example in 1998, the internal medicine outpatient clinic at the University of Alabama Birmingham received a walk-in from a previously healthy 26-year-old bodybuilder complaining of significant chest pains. The man, who had a history of moderate anabolic steroid use but who had not used any steroid preparations in the weeks leading up to his visit, revealed that he had continuously been using clenbuterol for nearly a month [Loki’s note: idiot]. During check-up, the man turned out to be completely fit and healthy with the only exception being a significant amount of left ventricle (heart) hypertrophy and cardiac dyskinesias (meaning distortion of muscle [in this case smooth muscle] activity)(20).
In fact, between 1988 and 1998, eight cases of medically-diagnosed cardiac hypertrophy have been reported in drug-using bodybuilders within the United States (21,22). We can assume many more went overlooked or unreported. Still, because of the steroid outlier (which could also be a potential factor in the pathology—or perhaps even the outright cause), the medical community has been unable to isolate clenbuterol’s true role in contributing to these instances of myocardial infarcation (20). Still, the researchers who have examined this phenomenon arrived at a conclusion that should give most clen user’s pause of thought. Namely that:
We suspect there may have been a synergistic role between the anabolicsteroid and clenbuterol. Hypothetically, the anabolic steroid may have caused cardiac hypertrophy, coronary artery spasm, or thrombosis. The clenbuterolmay have precipitated ischemia by producing intermittent tachycardia. Alternately, clenbuterol may have contributed primarily to the cardiac hypertrophy…(20)
Furthermore, clenbuterol ingestion (particularly excessive ingestion) has also been documented to cause tachycardia (sudden, rapid racing of the heart)(20,23,24), hypokalemia (23), hypophosphatemia (23), potassium depletion (24), taurine depletion (25), headaches (24), tremors (24), and vertigo (24). Now, it should be noted that the more severe of the aforementioned conditions have only been demonstrated in instances of clenbuterol overdose and are thus not directly applicable to carefully monitored doses within the 20-100mcg range. Nonetheless, clenbuterol is definitively a “big kid sympathomimetic,” and not a drug that lends itself to immoderation, recklessness, or just outright stupidity.
And for now, I’m afraid that’s just going to have to do it for Part I of our comprehensive look at Clenbuterol. Next issue we’ll get into receptor down-regulation, clenbuterol, the brain, and neuroprotection (for all my Chemically Correct homies), cycling, stacking recommendations, and potential novel uses for clenbuterol in the treatment of injuries and various diseases and conditions.

Preface: Part I Super Brief Quick Recap
Clenbuterol is a sympathomimetic drug. It is uber-lipolytic and potently anti-catabolic. It repartitions calories from fat deposits to skeletal muscle, and will initially kick more stimulation through your system than the sight of Jessica Alba in a two-or-less- piece, or for our female readers maybe Jude Law chopping wood or something (sorry, that’s as far as I can comfortably engage the latter half of the fantasy). It’s bad for your heart, and even worse taken with anabolic steroids, and is in general a drug that offers users significant cutting benefits, but at a very high potential cost to their health and well-being. In other words: if you choose to use it, realize you are doing so at your own risk.
Saying “Screw Loki, I’m Using This,” and Doing so at Your Own Risk
As mentioned in Part I, you get the good and the bad with clenbuterol. In particular, as athletes/bodybuilders, our three prime concerns are: 1. the potential for deleterious effects on cardiac function, 2. the impairment of exercise-performance capacity (see: a few sentences down), and 3. the eventual functional downregulation of your beta2 adrenergic receptors after continual exposure to clenbuterol, which is eventually going to downgrade the strength of clen’s lipolytic punch from “Early Mike Tyson” to “Late Mike Tyson”. So when using clenbuterol, obviously the informed and educated user should be looking to strike a balance to get as much of the benefits with as little ‘bad’ as possible.
Regarding clenbuterol’s potential to impair heart function and lead to cardiac complications, there’s really not too much you can do aside from keeping your clen dose as low and reasonable as possible, at a dosage where you’re still seeing effects. Obviously a beta-blocker would prevent the negative, but it is after all a beta-blocker, which isn’t exactly the kind of drug you want to stack with a beta adrenergic agonist if you want to see, well, anything positive.
Either a novel, selective beta1 antagonist or an angiotensin II type 1 blocker might make welcome contributions to the cellular well-being of your cardiac myocytes, but unless you saved the CEO of Merck from a recent bear attack or something, chances are you don’t have the kind of connections to acquire such drugs. Bottom line: dose in moderation. 40-80mcg/day should provide you all the clen you need to take advantage of its lipolytic and anti-catabolic effects without immediately giving your myocytes a Grade-A mauling.
Along similar lines, if work capacity—particularly aerobic—is a high priority for you, you’d do well to shop for a different diet drug (if not several). Clocking more cardio hours each week than strength training time? Consider your Spiropent privileges revoked if you aren’t stepping on stage for a contest a week from Tuesday. For starters, it stands to assume than any drug that can potentially exert significantly deleterious effects on the human heart isn’t prime weight-loss material for anybody needing iron aortas and slow, steady cardiac contractions to get them through that next triathlon or road-race.
Additionally, animal studies indicate that clenbuterol administration decreases muscle oxidative potential and expenditure efficiency, perhaps by preferentially increasing nonmitochondrial proteins &/or altering fiber-content (1,2). Reductions in cardiac capacity and structure, as well as VO2max, also seem to be implicated (3). And although in some studies consistent exercise training has been able to counteract some of clen’s performance-reducing effects, the general scientific consensus remains that chronic clenbuterol treatment is directly antagonistic to exercise performance in animals (4). In non-asthmatic humans, there is very little to indicate that beta-agonist drugs will improve anaerobic or aerobic work capacity (5,6,7).
So at low doses, you are at best breaking even. At high-doses, it is far more likely that your performance will be hampered and/or harmed through marked increases in systolic blood-pressure and impairment of the anaerobic expenditure process (8,9). This would hold particularly true in regards to activities like HIIT cardio and intensive, low-rest interval weight training.
Moreover, as previously noted in Part I, consistent clenbuterol use invariably leads to direct decreases in intracellular taurine and potassium concentrations (10) at higher doses. Taurine, as an important osmoregulator of cell-volume, is a very important asset to performance and plays a key role in signal transduction, muscle contraction, cardio-protection, protein synthesis, and cellular hydration in general (11,12,13,14). Thus, taurine supplementation in the 3-5g/day range should be considered an essential adjunct to clenbuterol use. Potassium supplementation, or a diet containing plenty of potassium-rich foods, would also likely help attenuate some of clenbuterol’s antagonistic effects towards exercise performance.
Lastly, we arrive at the issue of functional downregulation with the beta2 receptor. Given clen’s agonistic potency, and the differing molecular structure of the beta2 receptor as opposed to its beta1 and beta3 counterparts, it is only a matter of time in all chronic clenbuterol users before almost complete, system-wide desensitization of the beta2 receptor-class sets in (15,16). More specifically, in rats undergoing high-dose (4 mg/kg) clenbuterol treatment, soleus and medial gastrocnemius tests showed a 40-45% decrease in total beta-adrenergic receptor density, with the entirety of the decrease coming from beta2 desensitization (17;18).
Brotologists Run for Your Lives… It’s Science!!!
The specific mechanisms responsible for adrenergic downregulation of the beta2 seem to be heavily G-protein implicated (18). More specifically, researchers speculate that the process begins with the uncoupling of the receptor’s heterotrimeric G after acute exposure to the agonist (19). Eventually, with enough chronic stimulation, the receptor/arrestin [note: arrestins are proteins which can bind or uncouple heterotrimeric G proteins from G protein-coupled receptors] complex, which would normally be recycled to the cellular membrane after exposure to the agonist is halted, is instead translocated to the lysosomes (20).
Lysosomes, for those not aware, are essentially the unheralded cousins of the peroxisomes. While the peroxisomes tend to get all the shine because the PPARs are so pivotal in regulating metabolic substrate oxidation and adipocyte differentiation, the lysosomes are the guys who tend to handle the cellular ‘grunt work’—eating up bacteria, decaying organelles, and other byproducts your cell doesn’t really want hanging around in there. In this case, with chronic clenbuterol exposure, your cell doesn’t want yourbeta2 receptors hanging around anymore, and the lysosomes eventually just start taking them out, Mafioso-style, in a process known in “Whachu’ talkin’ bout Willis?” terms as ‘homologous desensitization.’ And, just like that, beta2-mediated lipolysis is suddenly closed for business. My. How the tables have turned.
Synthesizing Our Savvy and Dialing it All In
At this point, you should have a pretty good understanding of clenbuterol, in terms of its effects and mechanisms. So let’s put principle into practice and discuss how to take the plunge without going off the deep end.
Dosage
40-80mcg/day. If you are a newcomer to clenbuterol, start with an even lower dosage (10-20mcg) and assess your tolerance. Titration of dosing need be utilized only in regards to tolerance: if you know you can handle 60mcg of clenbuterol per day, and that’s your target, then get to that dosage as fast as possible and keep it there. There is no pragmatic need to ‘pyramid’ or ‘taper’ clenbuterol use above and beyond the stimulation factor, once you know the dosage you can tolerate and have selected an amount to run. And remember: because of the long, biphasic half-life, clenbuterol builds up in your system, a la DNP. A 40mcg dose on Monday noon and a second 40mcg dose the very next day means you’re already going to have circa ~60mcg active in your system after just two days, so bear that in mind.
Cycling
In my personal opinion, clenbuterol cycles are best kept to about 7 days in duration before cycling off for at least an equal period of time. Granted, based on the literature, you’ll still have significant catecholamine-mediated lipolysis kicking around in that second week, but—and again, taking half-life into consideration—your beta2s are going to definitely be cashed out by the end of week 2. Thus, rather than exposing yourself to significant temporary down-regulation at all (as well as the negative systemic effects, which will only be aggravated as the drug continues to build up in your system), why not use clenbuterol in more of a precise manner and get big-time bang for your buck?
Anecdotally, 99% of clenbuterol users say their first cycle was the ill na na, and subsequent cycles were far less effective at drastically influencing body-composition. Whether there is any merit to this notion or not, the fact of the matter remains that some fraction of the first, full-fledged receptor-desensitization that clenbuterol elicits may be irreversible, a supposition which lends even more credence to the idea of shorter and/or lower-dosed cycles. And remember, always take at least as much off time from clenbuterol as you spend on it.
Stacking
Much to my chagrin, chances are if you’re using clenbuterol in the first place you pretty much have no reservations about what you do to your body to achieve your fat-loss results. And by that same token, chances are you have no qualms with stacking a 1Fast400’s inventory-shelf worth of supplements alongside it just for the sake of expediting things a tad. So, for the sake of getting you conveniently cut ASAP so you can get the hell off the drug, here’s the stuff you want to look into:
Green Tea Extract:
EGCG, the principal active ‘weight-loss catechin’ in green tea is a catecholamine-O-methyltransferase (COMT) inhibitor. COMT is an enzyme which metabolizes catecholamines peripherally. Inhibiting COMT potentiates catecholamine-induced thermogenesis.
PhenoGen:
GPA, one of the three actives in PhenoGen, when administered concurrently with clenbuterol decreases clenbuterol-treatment-only impairments in response to exercise-induced increases in GLUT4 protein concentrations. GPA also increases beta-adrenergic receptor density in skeletal muscle, giving you more adrenergic receptors for clenbuterol to agonize, thereby accelerating its fat-burning properties.
T3/Trimax/Triac/etc:
While the author of this article loathes synthetic thyroid modulation with a passion, he does admit that it makes for a pretty ridiculous one-two fat-burning punch when combined with clenbuterol. T3, like GPA, upregulates beta-adrenergic receptor density in skeletal muscle. Additionally, T3 also increases uncoupling protein (UCP) expression in the mitochondria (thereby increasing metabolic rate and cellular respiration) and accelerates substrate-cycling/reformation in stored TAGs. Thirdly, as a potent anti-catabolic agent, clenbuterol also makes a good adjunct to the immensely catabolic T3, given its abilities to attenuate proteolysis, particularly that which takes place in the ubiquitin-proteasome pathway.
H.E.A.T. Stack:
This one, while it might not occur too many, makes significant practical sense assuming one is knowledgeable about his or her stimulant tolerance and is aware of the potential risks. The simple gist is that clenbuterol’s lipolytic effects are predominately beta2-mediated. Adding H.E.A.T. Stack in conjunction will allow the user to markedly increase beta1 and beta3 mediated lipolysis simultaneously, thereby creating a bonafide peripheral lipolytic jamboree, in addition to providing some much-needed appetite suppression—one of clenbuterol’s significant pharmacological shortcomings when it comes to dieting.
Miserly, risk-prone bastards could also use E/C in place of H.E.A.T. Stack, assuming they have no problems knowing that they are antagonizing the fed state and putting themselves at a much higher risk of negative cardiac and/or blood-pressure related interactions, both of which would be well above and beyond what one would be dealing with when using the much more benign and—dare I say—“classy” wink H.E.A.T. Stack.
Ketotifen:
A pharma anti-histamine that attenuates clenbuterol-induced beta2 receptor desensitization, allowing you to stay on longer and keep the ball rolling on lipolysis. Note: hopefully you will realize this is not necessarily an entirely a good thing. Also, please actually research this drug before just going out and getting all polypharmacological in the name of a never-ending clen cycle.
And That’s Almost All She Wrote
And thus we arrive at the end of our M&M examination of clenbuterol…
PSYCHE!!!
No, but with all seriousness, for the sake of this article meeting its deadline, this will conclude Pharmaceutical Phenotype Enhancement’s general installment on the diet drug clenbuterol. However, because I said at the end of Part I that I planned on discussing clen’s neurological effects, as well as its potential role as a curative for certain pathologies, and because I’m not a pathological liar, look for a “Clenbuterol Addendum” to pop up in good old Issue #30. Yes, I know. I live to give; I love my fans and puppy dogs very much; I am a Leo; I find Sprite’s cool, crisp, lemon-limey flavor very refreshing; and please direct all fan male to my secretary and Avant eunuch, Robboe. Cheers all.
