i'm prone to mpb, i found this out when i started the cycle im on now. 500mg test e/wk. i started with dbol as a kick start but dropped it after a week as my head was itchy and hair was coming out fast. now i'm on 1.25mg finasteride and use nizoral 2% eod. the hair thinning has slowed right down, may even of stopped (no itchy head or hair on the pillow anymore). i'm only 22 aswell, when i first noticed it i was pretty worried but i've come to terms with it now though.
