Ive been taking biogenetix for about 4 weeks now, and I have to say I am extremely impressed. I've put on 6 lbs. By BF% only went up from 12.6 to 12.7 so i know this is quality gains. I have taken a few cycles before and still have these results from gnc product. Anyone thinking of doing a cycle should try this product first. Im going to continue for another 4 weeks and compare these gains to my cycle, although i know it wont be as much weight, the LMM may be comparable.
