Methenolone Enanthate, widely known by its pharmaceutical brand name Primobolan, is a long acting anabolic compound derived from dihydrotestosterone (DHT) with a distinctly mild androgenic profile relative to most injectable anabolic compounds. CSD’s formulation delivers 100mg/mL in a 10mL multi dose vial in a stable oil based injectable format designed for controlled, precise handling in research settings.
The enanthate ester attached to Methenolone provides a half life of approximately 10–14 days, placing it in the long acting category alongside Testosterone Enanthate and Cypionate in terms of administration frequency. What distinguishes Primobolan from testosterone based compounds is its DHT derived structure. It does not aromatase under any circumstances, meaning it produces no estrogenic conversion regardless of dose. This non aromatizing characteristic makes it a frequently studied compound in research examining anabolic activity in the absence of estrogenic influence, and a useful reference compound in comparative androgen studies.
Primobolan has a well documented pharmaceutical history, having been clinically approved for use in treating muscle wasting and malnutrition conditions. Its relatively favorable androgenic to anabolic ratio and non aromatizing profile have made it one of the more extensively researched injectable anabolic compounds in the literature, with a research history spanning several decades across endocrine, sports science, and pharmaceutical contexts.

Injectable Primobolan (Methenolone Enanthate) is a dihydrotestosterone (DHT) derivative with a mild anabolic profile and very low androgenic activity. One of the most researched compounds for lean mass preservation, cutting protocols, and quality tissue accretion without significant water retention or estrogen related side effects. Methenolone does not aromatize to estrogen and has no progestin activity, making it one of the cleanest anabolic compounds in the research catalogue in terms of estrogen and prolactin management requirements. It was originally developed for muscle wasting and malnutrition research and has a long clinical history dating to the 1960s.
Injectable Primobolan (Methenolone Enanthate) and oral Primobolan (Methenolone Acetate) share the same active steroid nucleus but differ in ester, administration route, and bioavailability. Injectable Methenolone Enanthate bypasses first pass liver metabolism entirely, delivering the compound directly into systemic circulation at near complete bioavailability. Oral Methenolone Acetate is not 17-alpha alkylated making it less hepatotoxic than most oral anabolics but also significantly less bioavailable, with only approximately 30–40% of the oral dose reaching systemic circulation. Milligram for milligram, injectable Primobolan is considerably more effective and more cost efficient than the oral form.
Primobolan is most commonly researched alongside a testosterone base typically Testosterone Enanthate or Cypionate as its mild suppressive properties still reduce endogenous testosterone production requiring exogenous replacement. In cutting research, Primobolan is commonly stacked with Testosterone Propionate and Masteron for a lean, hard, non aromatizing combination. In lean mass research, Primobolan is studied alongside Testosterone Enanthate and occasionally Anavar (Oxandrolone) for quality tissue accretion without water retention or androgenic side effects.
Methenolone Enanthate has a half-life of approximately 7–10 days; typically administered once or twice weekly in research protocols. Twice weekly administration splitting the weekly dose into two equal injections produces more stable plasma Methenolone levels throughout the research cycle. Common research doses range from 400–800mg per week. At 100mg/mL this 10mL vial contains 1000mg total, sufficient for 1.25–2.5 weeks at typical research doses, making multiple vials standard for a full research cycle.
Yes! This batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 100mg/mL and compound identity as Methenolone Enanthate. A certificate of analysis is available.
