Primobolan Depot is an injectable steroid produced by Schering and sold in various parts of the world. It contains the steroid metenolone enanthate, which is a long acting anabolic with extremely low androgenic properties. The anabolic
properties of this steroid also are mild. In this injectable version, an enanthate ester is added to the steroid, which makes for a slow and gradual release from the site of injection. Its length of activity would thus be quite similar to
Testosterone enanthate, with blood levels remaining elevated for approximately two weeks.
