Drostanolone Enanthate | 100% good quality


Drostanolone (also known as dromostanolone) is a potent synthetic androgenic anabolic steroid similar to testosterone. Drostanolone is indicated in postmenopausal women with recurrent breast cancer, in a combined hormone therapy.


Drostanolone

Drostanolone, or dromostanolone, is an anabolic–androgenic steroid (AAS) of the dihydrotestosterone (DHT) group which was never marketed.[1][2][3] An androgen ester prodrug of drostanolone, drostanolone propionate, was formerly used in the treatment of breast cancer in women under brand names such as Drolban, Masteril, and Masteron.[1][2][3][4] This ester has also been used non-medically for physique- or performance-enhancing purposes.[3]

Like other AAS, drostanolone is an agonist of the androgen receptor (AR).[3] It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity.[3] As a DHT derivative, drostanolone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites.[3] While no data are available on the progestogenic activity of drostanolone, it is thought to have low or no such activity similarly to other DHT derivatives.[3] Since the drug is not 17α-alkylated, it is not known to cause hepatotoxicity.[3]

Chemistry[edit]

Drostanolone, also known as 2α-methyl-5α-dihydrotestosterone (2α-methyl-DHT) or as 2α-methyl-5α-androstan-17β-ol-3-one, is a synthetic androstane steroid and a derivative of DHT.[1][2][3] It is specifically DHT with a methyl group at the C2α position.[1][2][3]

History[edit]

Drostanolone and its ester drostanolone propionate were first described in 1959.[3][5] Drostanolone propionate was first introduced for medical use in 1961.[6]

Society and culture[edit]

Generic names[edit]

Drostanolone is the generic name of the drug and its INNBAN, and DCF.[1][2] It has also been referred to as dromostanolone.[1][2]

Legal status[edit]

Drostanolone, along with other AAS, is a schedule III controlled substance in the United States under the Controlled Substances Act.[7]
