I might as well elaborate. This guy is partially wrong. He is only right as it applies to professional male bodybuilders. Pct can not be compared to tylenol. In a study with exogenous testosterone, upon completion it took 4 months to see a change in testosterone levels. Pct is about that kick start. The adequate time off after is about faster bodily adaptation to stabilized levels. A pct with an estrogen receptive modulator acting as both an estrogen agonist and antagonist is important.
See by using weak estrogens, your breast tissue will not display estrogenic side effects. But the influx of the modulator causes an imbalance that makes the body want to produce t and dht. An AI (not something like high dose letro) can stop enzymes from estrogen conversion while also increasing testosterone. So then, when you come off, you have recovered testosterone levels, and you won't have rebound affects unless you are a dumbass, or can't recover from serms because you were on too long and no signal is strong enough for a reboot.
A mixture of clomid and tamoxifen work best because 2 weeks of tamoxifen only produces a modest increase in testosterone. Clomid works faster, but it is best to have both because of lnrh response. Hcg essentially makes the balls responsive to the incoming LH. So no its not a bandaid on a wound. It is is a reboot.
All of the essential vitamins and amino acids (daa is good) help the body start going on its own again. You talk to guys who are on for years and they fucked and need trt unless by some small odds a trip shot and pct works. For athletes like football players (and duh they are on shit throughout college) steroids give them an edge. That does not mean they need a bodybuilder regimen of blast/cruise.
Now for the guys who dont recover with pct. a month of a mildly suppressive, hell or very suppressive prohormone will not most likely fail to recover t levels within a month of pct.
Last point id like to make is some gains are definitely permanent especially with diet and exercise. This is attributed to general cellular hyperplasia that occurs with time (more often than not gh related), and the fact that you aren't a deflating balloon. There is a breaking point. Some bodybuilders come off and drop from 280 to 240 fairly lean. Will there be losses? absolutely. But 240 is above that 5'7" mans natural potential.
The body is resilient but transformations can be made with time. It is a marathon not a race. But yes, there is no way pros take 10 grams of steroids and a month pct and be fine. Less than a gram of test enth and you are g2g.
