Methenolone enanthate 1000mg/10ml vial Primobonex is an injectable version of the steroid methenolone. This is the same constituent in Primobolan orals (methenolone acetate), although here 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 Deca-Durabolin (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 prescribing guidelines for Primobonex recommend a maximum dosage of 200 mg at the onset of therapy, and a continuing dosage of 100 mg every week. Prolonged administration protocols generally call for a 100 mg dosage every 1-2 weeks, or 200 mg every 2-3 weeks. The usual administration protocols among male athletes call for a 200-400 mg per week dosage, which is taken for 6 to 12 weeks, which 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. Methenolone enanthate is often stacked with other (typically stronger) steroids in order to obtain a faster and more enhanced effect. During a dieting or cutting phase, a non-aromatizing androgen like Halotestin or trenbolone can be added. The stronger androgenic component here should help to bring about an added density and hardness to the muscles. On the other hand, one might add another mild anabolic steroid such as stanozolol. The result of such a combination should again be a notable increase in muscle mass and hardness, which still should not be accompanied by greatly increased side effects. Methenolone enanthate is also used effectively during bulking phases of training. In such a scenario, the addition of testosterone or boldenone would prove quite effective for adding new muscle mass without presenting any notable hepatotoxicity to the user.
