A while back I did a cycle of transdermal 4-ad with finaplix in it. Gains were great but it took my body nearly a year to recover(no sex drive). The worst part was the acne was absolutely horrible! All over my back, chest, and stomach. I had done a cycle of transdermal 4-ad before that and only had a mild breakout. My question is, out of all of the prohormones out there besides 4-ad, which are the most effective but least likely to cause acne?
