Forza Primobolan is a synthetic anabolic steroid with very little androgenic properties. It has been widely used by bodybuilders to build up muscle mass and strength. The drug is slow acting and the weight gain is gradual. Most users of this product indicate that the muscle mass build up takes anywhere from 6-8 weeks to develop. It is a preferred drug for the offseason. It actions are similar to Deca Durabolin, but needs to be administered at much higher doses. The drug is not as potent as other anabolic steroids in suppressing the synthesis of endogenous testosterone from the testes and hence the androgenic effects are much less.
