Accutane - Isotretinoin
Accutane, aka Isotretinoin, is literally topical Vitamin A. A natural derivative, technically, but still as close as it gets. Extremely useful in acne-treatment caused by steroid use. You need it most of the time with Deca-Durabolin, Trenbolone and Testosterone. Reduces acne and improves skin condition (after a period of dryness, most likely).
