My first cycle ever was a single vial of testosterone. I'll NVR forget, it was an 8 week pyramid run, starting at .5cc week 1, 1cc week 2, 1.5cc week 3, 2cc wks 4 and 5, back down to 1.5 wk 6, 1cc wk 7, and back to .5cc wk 8.
As god as my witness, I gained just over 20 lbs on that single vial. I trained and ate food as if my life depended on it, because I never thought I would be able to get gear again, and of course my thought process was like everyone else's, "just 1 and done" , yea right, lol. I was handed a piece of paper with chicken scratch writing on it on how to run the cycle. No internet to check on things, and unfortunately no PCT.
