some people are forgetting something!
a shot of 250mg of TE is only 140-150 mg of actual testosterone. So in reality, running 500 is more like 350mg of test. So you guys who are saying 250mg of TE is 2.5 times natural male test production, WRONG!
o and btw....I know of only one person who made great gains on 250 a week, and they happened to be ICN's which are slightly overfilled anyways. just a coincidence I guess 
I can only use my own blood work as an example not bro logic on a forum..i cruise on 250mg a week and this puts my test levels at over two times the high end of whats considered "normal" ,test depot to what its refered to in the medical practionaires guide is meant to be prescribed every 21 days but is left to the practionaires discretion as everyone is different..now if every 21 days will take the "average" persons blood levels back into the mid range of normal , what will doing a ml every 7 days do?
Personaly Id run 2 ml a week(500mg) for a first up but to say a ml wont do nothing is silly because it will send your test levels over the normal end of high end by quite a bit.
I started with low test levels also , from abuse of pro hormones but decided to just self prescribe as the doctors wanted to see if they could get my levels back to normal before stating on TRT..the rest is history and i never come off ..
