i like it...i think it works best of you're over 30...great for libido and good for muscle, but definitely not like 1 or 2 amps of sust as biotest tried to hype...trust me when i say i know the feeling of test and other types of juice...still, i like androsol and use it regularly...i'm about to order some 4 ad powder from www.kilosports.com and some isopropyl alcohol 99% and make my own for under $13 per bottle!!!
