The semi-synthetic steroid, norethisterone (19-Nor-17-alpha-ethynyltestosterone), was the first orally highly active progestin, which led to the development of the first oral contraceptive pills. Albert Bowers joined Syntex, in 1956 as research group leader; went on to publish more than 90 scientific papers on steroid research and originated ...
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.
The four testosterone esters are as follows; . 30 mg testosterone propionate [1]; 60 mg testosterone phenylpropionate [1]; 60 mg testosterone isocaproate [1]; 100 mg testosterone decanoate [1]
Testosterone cypionate is a prodrug of testosterone and is an androgen and anabolic–androgenic steroid (AAS). That is, it is an agonist of the androgen receptor (AR). Testosterone cypionate is converted by the body to testosterone that has both androgenic effects and anabolic effects; [ 4 ] still, the relative potency of these effects can ...
Stanford University academic Maurice L. Tainter learned of DNP's effect in raising the metabolic rate and causing weight loss and pioneered its use as a weight loss drug. [ 1 ] [ 38 ] Although he was aware of DNP's narrow therapeutic index , Tainter tried the drugs on obese patients and published successful results in 1933; average weight loss ...
Stanozolol, also known as 17α-methyl-2'H-androst-2-eno[3,2-c]pyrazol-17β-ol, is a synthetic 17α-alkylated androstane steroid and a derivative of 5α-dihydrotestosterone (DHT) with a methyl group at the C17α position and a pyrazole ring attached to the A ring of the steroid nucleus. [7]
Boldenone, also known as Δ 1-testosterone, 1-dehydrotestosterone, or androsta-1,4-dien-17β-ol-3-one, is a naturally occurring androstane steroid and a derivative of testosterone. [ 3 ] [ 4 ] [ 7 ] It is specifically testosterone with a double bond between the C1 and C2 positions.
Its introduction into commerce may have represented an attempted circumvention of the U.S. Anabolic Steroids Control Act of 1990 (along with its 2004 revision), since the law is, in part, drug-specific; [3] methasterone, as is the case with many designer steroids, was not declared a Schedule III class anabolic steroid in that act because it was ...
