Information: Mesterolone (Proviron) represents one of the oldest anabolic androgenic steroids on the market. A product of the giant pharmaceutical company Schering, it first appeared in 1934. Officially known as Mesterolone, it has appeared under many brand names over the years, but the proviron pharmacy france name has always remained dominant.
In many ways, Mesterolone is a unique anabolic steroid product. It shares strong similarities with (Drostanolone) Masteron and to a degree Oxandrolone (Anavar) and Stanozolol (Winstrol) but altogether it is its own unique animal. In a performance capacity, Proviron is not used to promote large mass buildup, although it may serve an important purpose during such a training phase.
