You will need MUCH higher doses that what the product recommends. My best results were from 1-AD at 900mg/day WITH some sort of andro-spray type thing (also at 3X the suggested dosage). This alone make PH's very costly.
They did work. Sort'a. I gained and kept about 6lbs in 10weeks or so. I think my peak weight gain was something like 14lbs, but that rapidly dropped after stopping the products. Considering that this was almost 10wk's with ZERO sex drive and some $600+ spent I am not entirely sure it was worth it.
