I tested Gakkic, and there should be a tester thread here. I saw some interesting stuff with it, from what I remember I did see a strength bump in the month I used it, but as widdoes pointed out it was more of a bump in reps then in overall wieghts.
After about a month it didnt really seem to do much, and having to take 8 pills pre workout was pretty ridiculous, especially those horse pills.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
