While by no means always necessary, some men may find the use of a 5-alpha reductase inhibitor to be useful. The testosterone hormone is metabolized by the 5-alpha reductase enzyme, which reduces the testosterone hormone to dihydrotestosterone (DHT). The DHT is what leads to the androgenic related effects. By incorporating a 5-alpha reductase inhibitor, you will reduce the hormones androgenicity. It will not be a complete reduction, but it will be significant. However, such inhibitors are not always recommended and should only be used as needed as they can hinder the potency of the testosterone hormone.
Then there are the cardiovascular problems. Because of the way they affect heart cells, anabolic steroids can cause chronic high blood pressure, as well as enlargement of the heart. Your cholesterol levels also get thrown out of balance, since your steroid-saturated body is producing more LDL cholesterol and less HDL cholesterol , which is the opposite of what the American Heart Association recommends. The hormonal effects of steroid use also increase your risk of prostate cancer (if you’re male) and can cause kidney and liver damage.
