PRODUCT NAME & PACKAGING

Primobolan Depot is listed in the official Spanish product information as 100 mg solution for injection, with each 1 mL ampoule containing 100 mg of metenolone enanthate. The excipients listed are benzyl benzoate and castor oil, and the verified pack presentation is one 1 mL glass ampoule, not a 10 mL multidose vial.

DESCRIPTION

Metenolone enanthate is classified as an anabolic steroid derived from androstane. The official technical sheet states that its anabolic effect exceeds its androgenic effect across a broad dose range, and that it promotes endogenous protein production, may improve general condition, stimulate activity, and increase appetite in appropriate clinical settings.

INDICATIONS

The verified Primobolan Depot labeling states that it is indicated for diseases and states requiring increased protein synthesis to improve the patient’s general condition or to help prevent damage from catabolic processes, including consumptive diseases, cachexia, and advanced carcinoma of the breast or genital organs in women. The same label explicitly states that anabolic steroids are not indicated to enhance muscle development in healthy individuals or to increase physical capacity.

DOSAGE & ADMINISTRATION

The official dosing guidance for the verified product is 1 ampoule intramuscularly every 2 weeks, then 1 ampoule every 3 to 4 weeks after a good initial response. In more severe protein-deficit states, the label allows more intensive clinician-directed schedules, and administration should be intramuscular only, with the solution injected very slowly.

MECHANISM OF ACTION

The official product information states that a single ampoule increases protein synthesis, evidenced by reduced nitrogen excretion, with effects lasting more than two weeks. After intramuscular injection, metenolone enanthate is released slowly from the injection site, split into metenolone and enanthic acid, and reaches peak active-substance levels at about 6 to 11 days after injection.

PRECAUTIONS

Verified contraindications include pregnancy or suspected pregnancy, prostate carcinoma, male breast carcinoma, severe hepatic or renal insufficiency, current or previous liver tumors, and hypersensitivity to the active substance or excipients. The official warnings also advise caution in patients with heart failure, coronary disease, hypertension, edema, epilepsy, migraine, diabetes, benign prostatic hypertrophy, and in adolescents because of risks related to virilization and premature bone maturation.

SIDE EFFECTS

The official adverse-reaction list includes edema, nausea, vomiting, diarrhea, excitation, insomnia, hypercholesterolemia, hypercalcemia, leukopenia, jaundice, and in adolescents premature epiphyseal closure with growth arrest. In women with marked sensitivity to androgenic stimuli, the label also notes possible acne, hirsutism, and voice changes, and warns that persistent voice effects may become irreversible if treatment continues after early symptoms appear.

STORAGE

The official storage instruction is to keep the product in the original packaging to protect it from light. The verified technical sheet also lists a 5-year shelf life for the approved product.
