Anabolic steroids can cause the development of acne. However, the extent to which it is experienced can be due to a number of varying factors, with the particular steroids and exact dosages used being primary. The skin´s sebaceous glands have a particularly high affinity to Dihydrotestosterone, which is an androgen the body naturally produces from testosterone via the enzyme 5-alpha Reductase. Increased sebaceous gland activity promotes oily skin which can combine with bacteria and dead skin (normal wear and tear) eventually causing pores to become clogged more quickly than the body can cleanse them. This of course, is preventable by using only particular steroids, cleansing the skin regularly, and perhaps using a topical anti-androgen.
The question is what do these injections do? Indu Tolani, a dermatologist, explains that steroids involve drug receptors. "Steroids help in producing proteins and preventing the effects of cortisol in muscle tissues resulting in an improved muscle mass. Gradually the muscles turn into biceps, triceps and six pack abs. They become three times bigger than its original size," she added.
There are specific doses for specific injections. Some need to be injected on a weekly basis. There are positives to such treatments. For instance, steroids are recommended by doctors to increase the appetite and sometimes they help in stimulating muscle mass in chronic wasting conditions like cancer and AIDS.
