However, at this point, Mexico had lost its status as a world leader in the synthetic hormone market, and the barbasco trade was declining, just as the root was becoming depleted in the wild. [5] Also during the 1970s, it became possible to produce steroids from soy phytosterols, including progesterone. This meant that barbasco was no longer ...
Laboratorios Syntex SA (later Syntex Laboratories, Inc.) was a pharmaceutical company formed in Mexico City in January 1944 by Russell Marker, Emeric Somlo, and Federico Lehmann to manufacture therapeutic steroids from the Mexican yams called cabeza de negro (Dioscorea mexicana) and Barbasco (Dioscorea composita).

Metandienone, also known as 17α-methyl-δ 1-testosterone or as 17α-methylandrost-1,4-dien-17β-ol-3-one, is a synthetic androstane steroid and a 17α-alkylated derivative of testosterone. [7] It is a modification of testosterone with a methyl group at the C17α position and an additional double bond between the C1 and C2 positions. [ 7 ]
This is a complete list of androgens/anabolic steroids (AAS) and formulations that are approved by the FDA Tooltip Food and Drug Administration and available in the United States.
