Primoxyl (Methenolone Acetate) is a brand name for the anabolic steroid methenolone acetate. This agent is very similar in action to Primobolan Depot (methenolone enanthate), except here the drug is designed for oral administration instead of injection. Methenolone acetate is a non-c17-alpha-alkylated oral steroid, one of only a few commercially available oral agents that presents limited liver toxicity to the user. Itis also highly favored for its properties as a moderately effective anabolic with low androgenic andno estrogenic properties. It is, likewise, commonly used during cutting phases of training, when lean tissue growth and solid muscularity, not raw bulk, are the key objectives. Methenolone is a derivative of dihydrotestosterone. It contains one additional double bond between carbons 1 and 2, which helps to stabilize the 3-keto group and increase the steroid’s anabolic properties, and an additional 1-methyl group, which protects the steroid against hepatic metabolism. Primobolan makes use of methenolone with a carboxylic acid ester (acetic acid) attached to the 17-beta hydroxyl group to further help protect it from oxidation during oral administration. Studies have demonstrated the methenolone is an effective oral anabolic agent in both the acetate and unesterified forms.
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability. This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.
The prescribing guidelines for Primobolan recommend a maximum daily dosage of 100-150 mg per day. The usual administration protocols for physique- or performance-enhancing purposes call for 75-150 mg daily, which is taken for 6 to 8 weeks. This level is sufficient to impart a measurable anabolic effect, although one usually doesn’t expect to achieve great gains in muscle mass with this drug.Instead, Primobolan is utilized when the athlete has a specific need for a mild anabolic agent, most notably in cutting phases of training.Due to its mild nature, Primobolan is often used in conjunction with other steroids for a stronger effect. In such cases, a slightly lower dose is often used (50-100 mg per day). During a dieting or cutting phase, thought to be its primary application, a non-aromatizing androgen like Halotestin ortrenbolone is often added. Such combinations would enhance the physique without water retention,and help bring out a harder and more defined look of muscularity. Non-aromatizing androgen/anabolic stacks like this are very popular among competing bodybuilders, and prove quite reliable for rapidly improving the contest form. This compound is also occasionally used with more potent androgens during bulking phases of training. The addition of testosterone, Dianabol or Anadrol 50 is common, although the gains are often accompanied by some level of smoothness due to the added estrogenic component, as well as hepatotoxicity in the case of the latter two agents.
The prescribing guidelines for Primobolan do not offer separate dosing recommendations for women, although it is indicated that women who are pregnant, or may become pregnant, should notuse the drug. Female athletes generally respond well to 50-75 mg daily, with no signs of virilization symptoms. One would not expect a tremendous amount of muscle mass with this drug, and instead find a slow and steady (quality) increase. Some women choose to further add-in other anabolics such as Winstrol or oxandrolone, in an effort to increase the muscle-building effectiveness of a cycle. While both of these compounds are quite tolerable, one must be sure not to use too high an accumulated dosage. Taken at too high a dosage, these weak anabolics can quickly cause masculinizing side effects.
