You better believe it!
1-AD has made me grow hair in places I didn't think I ever would, I.E. my biceps (very light right now). It also made my chest hair spread out and it made all my body hair grow much thicker. The hair on my head, however, is a different story. 1-AD drastically accelerated the *tiny* amount of male pattern baldness I had at the time I started it. BUT, if you want to seriously increase your strength and size, 1-AD will do it better than any other supplement I have taken yet (gee, maybe because the liver converts it into a bonafide steroid, unlike any other PH, all of which are rendered 95% inactive by the liver).
On a side not, I NEVER experienced any of the sides that I had while on 1-AD with 4-AD. Then again, I never really though 4-AD was worth much of anything (at least by itself), and I was taking 1.5 grams of it a day for a while.
