i just recently got this d-ball and i know its legit cause i'm getting gains but my buddy is taking the exact same stuff and not noticing anything. they are 25 mg tabs taking one a day. i would tell him to take 2 a day but when i take mine (one a day) i get a serious enough pump and it kills my back. he's eating 5 times a day with 2 protein shakes a day as well. i don't really know what to tell him anymore exact to take 2 pills/day.
