Steroids can worsen existing skin pathologies. Athletes being treated for acne often stop responding to normal treatment regimens if they also continue to use the drugs. Some cases of comparatively benign acne can progress to the disfiguring inflammatory types. Psoriasis is an autoimmune disease in which, for unknown reasons, immune cells attack skin cells, resulting in red, scaly patches. One bodybuilder had controlled his psoriasis condition through the use of a topical cream, but when he began using steroids, his condition considerably deteriorated. Eventually his psoriasis became resistant to treatment. But when he stopped using steroids, the psoriasis stabilized and again responded to simple skin-cream treatment. 6
The study I found from that year examining a topical anti-androgen and its effects on the sebaceous glands was very interesting. When a topical anti-androgen was used on rodents, the scientists noted that sebaceous glandular and ductal regression was quite profound. This strongly suggests that a topical anti-androgen could effectively counteract endogenous androgens resulting in a suppression of growth of the sebaceous glands while leaving serum concentrations of both testosterone and dihydrotestosterone intact and not reduced (5). This means, for all intents and purposes, that Nizoralâ€™s anti-androgenic effect on your skin will prevent acne, without it having a systemic effect on your body. In simplest terms, it will leave 100% of the muscle building effects imparted by the steroids you are taking totally unaffected.
