the synthesis of methasterone is first mentioned in the literature in 1956 in connection with research conducted by syntex corporation in order to discover a compound with anti-tumor properties.[1] this initial mention is elaborated upon in a 1959 research journal article, where its method of synthesis is discussed in greater detail, its tumor inhibiting properties are verified, and it is noted as being a “potent orally active anabolic agent exhibiting only weak androgenic activity.”[2] the results of subsequent assays to determine methasterone’s anabolic and androgenic activity were published in vida’s androgens and anabolic agents, a dated but still standard reference, where it was noted that methasterone possessed the oral bioavailability of methyl-testosteronewhile being 400% as anabolic and 20% as androgenic, yielding a q-ratio (also known as an anabolic to androgenic ratio) of 20, which is considered very high.
