Testosterone Propionate 100 - Androlex

Testosterone propionate’s legacy began in 1937 with Schering AG’s Testoviron®, the first injectable testosterone ester introduced to medicine. Its release followed the 1935 synthesis of testosterone, offering doctors a solution to the hormone’s short half-life. With propionate, the active substance remained in circulation for several days, significantly improving treatment feasibility. Its use expanded rapidly through the 1940s–50s, becoming not only a clinical mainstay but also a favored anabolic among early strength athletes. Though longer esters have taken precedence, its historic role ensures continued availability.
