Boldione, also known as androstadienedione or 1-dehydroandrostenedione, as well as 1,4-androstadiene-3,17-dione, is an important industrial precursor for various steroid hormones. Boldione is a direct precursor (prohormone) to the anabolic steroid boldenone (1,4-androstadiene-17beta-ol-3-one). It is advertised as a highly anabolic/androgenic compound promoting muscularity, enhancing strength and overall physical performance, and is available on the Internet and in health stores. Boldione was marketed as a prohormone “dietary supplement” for many years in the mid-2000’s, but it is truly a potent precursor (ie. converts in the body) to the anabolic steroid Boldenone. In 2005 the Anabolic Steroid Control Act of 2005 classified boldenone as a Schedule III controlled illegal steroid.

Stanozolol is a synthetic anabolic steroid derived from dihydrotestosterone. It is indicated prophylactically to decrease the frequency and severity of attacks of angioedema. In rare cases, serious and even fatal cases of liver problems have developed during treatment with stanozolol. Anabolic steroids may increase sensitivity to anticoagulants; therefore, dosage of an anticoagulant may have to be decreased in order to maintain the prothrombin time at the desired therapeutic level.

STANOLONE, also known as dihydrotestosterone, is a potent androgenic metabolite of testosterone and anabolic agent for systemic use. It may be used as a replacement of male sex steroids in men who have androgen deficiency, for example as a result of the loss of both testes, and also the treatment of certain rare forms of aplastic anemia which are or may be responsive to anabolic androgens.
