Proviroxyl 25 - Kalpa Pharmaceuticals

First appearing in 1934, Mesterolone (Proviron®) was developed by Schering as an oral androgenic treatment for male hormone deficiency. It entered clinical practice even before testosterone propionate, offering an early alternative to injectable therapy. Though mild in anabolic strength, Mesterolone’s minimal impact on endogenous hormone production made it well-suited for long-term use. It saw continued prescription across Europe and Latin America, outlasting many other early steroid formulations in therapeutic relevance.
