The usual administration among male athletes is a 200-400 mg per week dosage, which is taken for 6 to 12 weeks. Such amount is sufficient to promote very noticeable increases in lean muscle tissue. It is, however, not unusual to see the drug taken in doses as high as 600 mg per week or more, although such amounts are likely to highlight a more androgenic side of methenolone, as well as exacerbate its negative effects on serum lipids.

Primabol-100 is an injectable version of the steroid methenolone enanthate. An enanthate ester is used to slow the steroid\’s release from a site of injection. Methenolone enanthate offers a similar pattern of steroid release as testosterone enanthate, with blood hormone levels remaining markedly elevated for approximately 2 weeks. Methenolone itself is a moderately strong anabolic steroid with very low androgenic properties. Its anabolic effect is considered to be slightly less than nandrolone decanoate on a milligram for milligram basis. Methenolone enanthate is most commonly used during cutting cycles, when lean mass gain, not a raw mass increase, is the main objective. The combination of strong anabolic, weak androgenic, and non-estrogenic nature of this drug makes the methenolone enanthate a very desirable for building lean muscularity without side effects.
