Proviron represents one of the oldest anabolic androgenic steroids on the market. A product of the giant pharmaceutical company Schering, it would first appear in 1934. Officially known as Mesterolone, it has appeared under numerous brand names over the years, but the Proviron name has continually remained dominant. It has also remained one of the most misunderstood anabolic steroids among steroid users.
This is an injectable form of methenolone enanthate depot – an anabolic steroid with pronounced anabolic and moderately androgenic properties. Rimobolan enanthate is preferred by many bodybuilders because of its scarce side effects.
