Primobolin is the injectable version of the anabolic steroid methenolone.
As a injectable version of methenolone, 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.
Methenolone itself is a long acting anabolic, with extremely low androgenic properties.
It’s anabolic effect is also quite mild, its potency is considered to be slightly less than Deca Durabolin on a milligram for milligram basis.
Primobolan Depot is a predominantly anabolic steroid, as well as a DHT derivative so it will also maintain androgenic qualities.
It does not convert to estrogen, induces low water retention and a distinct lack of gyno. Some fat burning has also been noted with it’s use. In fact, the drug can also (theoretically) act as an anti-estrogen to a lesser extent.
Primobolan is somewhat disappointing in doses under 400mgs/week, and is commonly be stacked with at least one strong anabolic compound,
Testosterone being the obvious choice here. For women, it is usually taken alone with very good results from 100mgs/week. Muscle gained with Promobolan is usually of a high quality and usually (anectdotally) was retained quite well after discontinuance.
Primobolan depot should, in theory have only a slight impact on the Hypothalamic-Pituitary-Testes-Axis (HPTA), and thus not totally shut down natural testosterone production. Women tend to use this product alone, while men need to use at least one other compound with it in order to recognize any sort of appreciable weight gains.
Testosterone, Equipoise, and Deca Durabolin are popular additions to cycles containing primobolan, when used by men. Primobol is a brand of Primobolan made by Alpha-Pharma, and is currently the best bet for obtaining a real version of this product, produced by a pharma company.
