I decided to take it for 3 months at 10/20mg a day while on a very large cycle of tren. Tren with Test always gave me acne, but tren alone did nothing (found this out later i get no sides from just tren even at 2g week.) Anyways this shit is the best stuff i have ever tried for acne. I started out at 10mg a day for the first month. It basically stopped new ones from forming. 20mg a day completely cleared everything up within a few weeks. Worst side effect was dry lips and sometimes dry mouth but i drank so much water i didnt notice most of the time for either. always have chap stick handy. Hope this helps and im not too late to the convo
