I'll put it to you like this, for the sake of not bashing some of our trusted UGL's.... I was taking test at 750mg per week from a place, that if you've been juicing for a while, you have bought from them before. With this particular Test E 250, at a cc and a half, twice a week.... I had moderate acne on my back, really very little.
Then I got into homebrew and got a very pure product and a very great source and got some Test E and made 250. I figured since I was on this popular UGL's 250 at 750 a week that I should start at 750 of my own stuff! Well this shit was so much more powerful, just in the gym I felt way more jacked but using acne as a comparison, about 3 weeks into my "homebrew cycle at 750 a week" I had acne on my forearms, on my legs, shoulders, and son of a bitch... on my fucking feet tooo!!!!!
Dropped down to 500 a week and about 2 weeks later my acne went to about what it was at 750 of the popular UGL.
Food for thought!
