methyldiazinol methyldiazinol methyldiazinol (also known as 3,3-azo-17α-methyl-5α-dihydrotestosterone, 3-azi-17α-methyl-dht, or 3,3-azo-17α-methyl-5α-androstan-17β-ol) is a synthetic and orally active androgen/anabolic steroid (aas) which was never marketed. it is a 17α-methylated derivative of dihydrotestosterone (dht); specifically, it is the c3 azi (i.e., 3,3-azo) analogue of mestanolone (17α-methyl-dht). the drug has been found to possess a high ratio and dissociation of myotrophic to androgenic activity; relative to methyltestosterone, its ratio was 15 (3:0.2), among the highest observed. methyldiazinolclinical dataother namesmethyldiazirinol; 3,3-azo-17α-methyl-5α-dihydrotestosterone; 3,3-azo-17α-methyl-dht; 3,3-azo-17α-methyl-5α-androstan-17β-ol; 3-azi-17α-methyl-5α-androstan-17β-olroutes ofadministrationby mouthdrug classandrogen; anabolic steroididentifiers iupac name (5s,8r,9s,10s,13s,14s,17s)-10,13,17-trimethylspirophenanthrene-3,3'-diazirine]-17-ol cas number2429-17-6pubchem cid112500385chemspider52084890unii7aa03ap597chemical and physical dataformulac20h32n2omolar mass316.489 g·mol−13d model (jsmol)interactive image smiles c12ccc3(c1cc42cc5(4cc5(c)o)c)n=n3 inchi inchi=lmnfackykjijhj-phfhyrsdsa-nkey:1s/c20h32n2o/c1-17-10-11-20(21-22-20)12-13(17)4-5-14-15(17)6-8-18(2)16(14)7-9-19(18,3)23/h13-16,23h,4-12h2,1-3h3/t13-,14+,15-,16-,17-,18-,19-/m0/s1
