Saps thanks again very good reading you know your shit and thanks for taking the time to help a newbi like me that hasnt done his homework but the more i read the more confussed i get i copied and pasted this ,its the kind of shit that confusses me
If you've read some of my posts on other boards, you probably already have seen that I advocate suggesting low doses for beginners & nbsp;. Why jump into 600mg per week of test as a first or second cycle when it is highly likely you will get great gains using 200-300mg (in initial cycles)?
I keep seeing people write that 200mg of testosterone per week does nothing more than shut down a man's natural test production and bring him near "normal levels"--this is not quite correct (part of the statement is correct part of it is not). This incorrect statement has endured probably because someone wrote down thier idea/theory of what happens in the body, it sounded good, and other people repeated it. But, it is not correct. Yes, 200mg of a long lasting ester of testosterone will shut down natural test production, BUT the amount of 200mg of a long lasting ester of testosterone is more than twice the "normal levels" of test in the body of a healthy non-steroid using male. Therefore, 200mg of a long lasting ester of testosterone per week is far more than enough to grow on.
(I explain more below)
I was paranoid about side effects of testosterone on a normally functioning body, so I had my blood levels checked while on 200-250mg per week. The results of the tests indicated that the amount of testosterone in my blood was more than twice the high end of the normal range (The normal free testosterone range is 50.0-210.0 pg/ml*. My levels were found to be near 550 pg/ml). I also talked to my doctor and UPJOHN nurses a lot about using testosterone at these doses. Here's a brief bit of what I've learned from my doctor, the UPJOHN nursing staff (UPJOHN was the original manufacturer of Depo-testosterone a.k.a Testosterone Cypionate. The rights of Depo-testosterone was sold to PFIZER which now produces it under the name PHARMACIA), and professional medical documents:
*--NOTE: pg/ml is the correct unit notation.
Using a long acting ester testosterone (CYP and ENAN) does not mimic the normally functioning male body's circadian rhythm (daily rise and fall of testosterone). Testosterone, in a normally functioning body, does not explode up to high levels then gradually fall over a 1-2 week period as it does when injecting a testosterone such as CYP or ENAN. On the contrary, the body produces a small amount each day which is far below 200mg (It's around 10mg). That small amount is concentrated at the beginning of the day and then falls low by the end of the day. This process repeats itself every day and by the end of two weeks, a normally functioning body produces approximately 140mg of testosterone (appx. 70mg per week).
The use of long acting esters are in theory supposed to slowly release the testosterone over a two week period, but this is not quite what happens. To keep it simple, the delay of the esters actually allows large amounts of testosterone to build up--especially if you are taking 200mg every week as opposed to once every two weeks (biweekly) which is what the dose is supposed to be. (I'm simplifying here). Remember the "normally functioning" male produces only (appx.) 70mg per week (=140mg per two weeks). The dose doctors are recommended to perscribe is 200mg every 2 weeks (biweekly), but they tend to give 200mg every week.
So, it is fallacious reasoning to compare the TOTAL amount of testosterone produced in daily spurts in a normally functioning body over a 2 week period to the same amount of testosterone injected in one shot at the beginning of a week and reshot every week (before the previous week's dose is used up). The latter case (injections once per week) results in an overlap and build up of dose which causes the levels of testosterone to be HIGHER than normal. (Remember the shots should actually be 200mg every TWO weeks--not every week). These excess levels of testosterone are sufficient to build lean body mass faster than the "normally functioning" male.
In other words: addding up what the average male body produces per week then comparing that to the amount that is shot every week is like comparing apples to oranges. There is a whole diferent set of advantageous reactions happening in the body when it is given a full
2-week load (200mg) at the beginning of a week as opposed to getting naturally occuring, small, daily spurts of appx 10mg over the same period of time (2 weeks).
This is why a low dose cycle can yeild REASONABLE gains. Understand, I'm not talking mega-huge-fast gains. I'm talking noticably-faster-than-normal gains, which when coupled with a strict diet, sufficient rest and an excellent bodybuilding work ethic, can yeild large, solid gains (especially early in a person's cycle experience).
