Methyl-1-testosterone (M1T; developmental code name SC-11195), also known as 17α-methyl-4,5α-dihydro-δ 1-testosterone (17α-methyl-δ 1-DHT) or 17α-methyl-5α-androst-1-en-17β-ol-3-one, as well as methyldihydroboldenone, is a synthetic and orally active anabolic–androgenic steroid (AAS) [1] which was never marketed for medical use.
Methyltestosterone, sold under the brand names Android, Metandren, and Testred among others, is an androgen and anabolic steroid (AAS) medication which is used in the treatment of low testosterone levels in men, delayed puberty in boys, at low doses as a component of menopausal hormone therapy for menopausal symptoms like hot flashes, osteoporosis, and low sexual desire in women, and to treat ...
In August 2020, the U.S. Food and Drug Administration (FDA) became aware of nitrosamine impurities in certain samples of rifampin. [62] The FDA and manufacturers are investigating the origin of these impurities in rifampin, and the agency is developing testing methods for regulators and industry to detect the 1-methyl-4-nitrosopiperazine (MNP ...
Examples: testosterone undecanoate. Removal of a double bond between the C4 and C5 positions in testosterone, otherwise known as 5α-reduction, confers several-fold increased AR agonist activity to testosterone. The same is not true in the case of 19-nortestosterone derivatives, in which the opposite is the case.

Methylstenbolone, also known as 2,17α-dimethyl-δ 1-4,5α-dihydrotestosterone (2,17α-dimethyl-δ 1-DHT) or as 2,17α-dimethyl-5α-androst-1-en-17β-ol-3-one, is a synthetic androstane steroid and a 17α-alkylated derivative of DHT. It is the 17α-methylated derivative of stenbolone, as well as the δ 1-isomer of methasterone (2α,17α
Dimethyltrienolone is an extremely potent agonist of the androgen and progesterone receptors and hence AAS and progestogen. [1] In animal bioassays, it was shown to possess more than 100 times the anabolic and androgenic potency of the reference AAS methyltestosterone. [1]
