Desoximetiltestosterona CAS:3275-64-7

Desoxymethyltestosterone (DMT), known by the nicknames Madol and Pheraplex, is a synthetic and orally active anabolic–androgenic steroid (AAS) and a 17α-methylated derivative of dihydrotestosterone (DHT) which was never marketed for medical use. It was one of the first designer steroids to be marketed as a performance-enhancing drug to athletes and bodybuilders.

Desoxymethyltestosterone is sometimes abbreviated as DMT, though it should not be confused with the hallucinogen dimethyltryptamine, which is also known by the same acronym.

In animal studies, desoxymethyltestosterone has been found to bind to the androgen receptor (AR) about half as strongly as DHT, and to cause side effects that are typical of 17α-alkylated AAS, such as liver damage and left ventricular hypertrophy when taken in higher doses.

Desoxymethyltestosterone is unusual in that it is structurally a 2-ene compound, lacking the 3-keto group present in almost all commercial AAS (with ethylestrenol being a rare and notable exception). This does not mean it is a weak compound, and clinical research has determined that it is a fairly potent oral agent.[2] Rat studies indicate that desoxymethyltestosterone has an anabolic effect 160% that of testosterone while being only 60% as androgenic, giving it a Q ratio of 6.5:1.[3] Because of this favorable ratio, experiments in orchiectomized rats have demonstrated that treatment with desoxymethyltestosterone resulted only in a stimulation of the weight of the levator ani muscle; the prostate and seminal vesicle weights remained unaffected leading the authors of one study to characterize desoxymethyltestosterone as a powerful AAS with attributes of a selective androgen receptor modulator (SARM) and some indication of toxicity.
