Its basicly 2,17 dimethyl dht....and androstane derivitive....unsure what effect the methyl on the 2nd position will have on kinetics,possibly greater binding to shbg or albumin,,maybe decreases clearance rate, half life increase over 17 alpha methyl dht(mestanolone).. steric hindrance may increase and/or decrease androgen/anabolic properties(if in fact this product contains the proposed chemical and correct dosage) I would say give it a try if you have the money to spare and tell us what you thought of the product. give it a try though and let us know,,word of mouth is how 1-ad got started,,,you might be the first to start a new wave of prohormones.... also the avant labs forum has a few posts on this supplement. Out of all the upcoming and current new wave of prohormones/steroid post ph ban,,by chemical structure alone this product has my greatest attention.
