An androgen prohormone, or proandrogen, is a prohormone (or prodrug) of an anabolic-androgenic steroid (AAS). They can be prohormones of testosterone or of synthetic AAS, for example, nandrolone (19-nortestosterone). Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. [1]

This is a list of androgens/anabolic steroids (AAS) or testosterone derivatives. Androgen esters are mostly not included in this list. The major classes of testosterone derivatives include the following (as well as combinations thereof): Testosterone derivatives: direct derivatives of testosterone not falling into the groups below
This is a complete list of androgens/anabolic steroids (AAS) and formulations that are approved by the FDA Tooltip Food and Drug Administration and available in the United States. AAS like testosterone are used in androgen replacement therapy (ART), a form of hormone replacement therapy (HRT), and for other indications.
Testosterone is in the androgen family of medications. [9] Testosterone was first isolated in 1935, and approved for medical use in 1939. [12] [13] Rates of use have increased three times in the United States between 2001 and 2011. [14] It is on the World Health Organization's List of Essential Medicines. [15] It is available as a generic ...
A low testosterone level (hypogonadism) in men may be treated with testosterone administration. Prostate cancer may be treated by removing the major source of testosterone: testicle removal (orchiectomy); or agents which block androgens from accessing their receptor: antiandrogens.
The EC 50 of androstanolone for activation of the AR is 0.13 nM, which is about 5-fold stronger than that of testosterone (EC 50 = 0.66 nM). [43] In bioassays, androstanolone has been found to be 2.5- to 10-fold more potent than testosterone. [41] Upon intramuscular injection in rats, androstanolone is about 1.5- to 2.5-fold the potency of ...
The drug is described as a relatively weak androgen with partial activity and is rarely used for the purpose of androgen replacement therapy, but is still widely used in medicine. [2] [12] [15] [3] Mesterolone is used in androgen replacement therapy at a dosage of 50 to 100 mg 2 to 3 times per day. [16
