Methylstenbolone, known by the nicknames M-Sten, Methyl-Sten, and Ultradrol, is a synthetic and orally active anabolic–androgenic steroid (AAS) and a 17α-methylated derivative of dihydrotestosterone (DHT) which was never introduced for medical use.
[2] [3] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). [2] [6] It has strong androgenic effects and weak anabolic effects, which make it useful for producing masculinization. [2] The drug has no ...
Metandienone, also known as 17α-methyl-δ 1-testosterone or as 17α-methylandrost-1,4-dien-17β-ol-3-one, is a synthetic androstane steroid and a 17α-alkylated derivative of testosterone. [7] It is a modification of testosterone with a methyl group at the C17α position and an additional double bond between the C1 and C2 positions. [7]
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.
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
CDMT was the key steroid administered to approximately ten thousand East German athletes as part of a secret doping program, known as State Plan Topic 14.25, often without them knowing the nature of the "vitamins" they were forced to take. The program remained in place from about 1968 until the collapse of the German Democratic Republic in 1989.
Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. [138] Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities. [82]
Androstanolone, or stanolone, also known as dihydrotestosterone (DHT) and sold under the brand name Andractim among others, is an androgen and anabolic steroid (AAS) medication and hormone which is used mainly in the treatment of low testosterone levels in men. [2] It is also used to treat breast development and small penis in males. [2]
