yeah I haven't had a lot of luck finding it either. My idea instead was to decide whether my acne (shoulders, back mostly) was a side effect from DHT (I was using Masteron), progesterone (I was using deca), or estrogen. The acne was terrible whether I was using an AI and an anti-estrogen or not, so I proceeded assuming that either DHT or progesterone was the culprit. I used dutasteride that I got from purity solutions in order to combat DHT-derived sides, but the acne persisted. This suggested that either the acne was progesterone-related, or the dutasteride was bunk, or perhaps that I was wasting my time trying to eliminate acne while using steroids. I just get acne. There's nothing much I can do except wash 2 or 3 times a day. I'm not using accutane. I punish my body enough; if it needs to act out I let it.
