From what I have read, seen, and talked to numerous phisicians about is that you should be at least 20 before messing with your PH. I have done the 1-AD, and it made me sleep a great deal, and I ended up getting a slight case of gyno even with the 6-OXO post cycle. If you do try it, just like i said in another post, get a bunch of Nolvadex before you start. If you stack it you should know that 4-AD does convert to estrogen, but 1-AD doesnt. if you try it I hope it works well for you. Try a search on
www.discussfitness.com , there is a good amount of info and stories from users of 1-AD.
