Primobolan (Methenolone)

Among the whole variety of anabolic steroids, primobolan (methenolone) has the least androgenic effect. It belongs to the category of prolonged-action steroids. This drug is a derivative of dihydroboldenone.

Methenolone dissolves for a long time from the injection site, due to the inclusion of ether (enanthate) in the composition. Due to this, the period of activity of the drug increases up to 16 days.

The drug is available both in tablet form and in the form of ampoules (injections). In this case, the purchase of ampoules is preferable. Primobolan injections will cost less than tablets, and their effectiveness is much higher.

Tablets are a more expensive and less prolonged version of methenolone. Their duration is less than 5 hours. Taking tablets does not cause toxic effects on the liver. This is their main advantage.

Methenolone injections are sold under the following names: Primobol, Primobolan Depot and Primover. The duration of their activity is 16 days. Despite the strong pain during administration, the vast majority of athletes prefer the injectable form for its effectiveness.
