Methenolone Enanthate Injection is an anabolic-androgenic steroid (AAS) used to promote muscle growth, support recovery in catabolic states, and treat certain medical conditions associated with muscle wasting. It is the long-acting ester form of methenolone, which allows for slower absorption and sustained effects.

Here are the key details:


1. Composition and Form

  • Active ingredient: Methenolone enanthate.

  • Supplied as a sterile solution for intramuscular (IM) injection, typically in an oil base.

  • Available in single-dose ampoules or multi-dose vials.


2. Mechanism of Action

  • Binds to androgen receptors in muscle and other tissues.

  • Promotes protein synthesis and nitrogen retention, supporting muscle growth and strength.

  • Stimulates red blood cell production, enhancing oxygen delivery to tissues.

  • Has low estrogenic activity, reducing the risk of water retention and gynecomastia compared to other steroids.


3. Indications

  • Medical use (historical or limited):

    • Muscle wasting due to chronic illness, trauma, or severe weight loss.

    • Certain cases of delayed puberty or hypogonadism in males.

  • Non-medical use: sometimes used in bodybuilding or athletic performance enhancement (not recommended due to safety concerns).


4. Administration

  • Given intramuscularly, usually every 1–3 weeks depending on dose and clinical goal.

  • Long-acting ester allows for less frequent injections compared to methenolone acetate.

  • Dosage should be tailored based on body weight, condition, and response, under medical supervision.


5. Side Effects

Androgenic effects:

  • Acne, oily skin.

  • Increased body/facial hair growth.

  • Male pattern baldness in predisposed individuals.

Endocrine effects:

  • Suppression of natural testosterone production with prolonged use.

  • Mood changes, irritability, or libido alterations.

Cardiovascular and metabolic effects:

  • Changes in cholesterol (lower HDL, higher LDL).

  • Potential cardiovascular strain if misused at high doses.

Other effects:

  • Minimal liver toxicity compared to oral anabolic steroids.

  • Rare: premature epiphyseal closure in adolescents.


6. Contraindications

  • Known hypersensitivity to methenolone or other steroids.

  • Pregnancy and breastfeeding (risk of virilization).

  • Active prostate or breast cancer in men.

  • Severe liver, kidney, or cardiovascular disease.


7. Precautions

  • Monitor liver function, lipid profile, and hormone levels during prolonged therapy.

  • Avoid combining with other anabolic steroids without medical supervision.

  • Long-term use may require post-therapy management to restore natural testosterone production.


8. Storage

  • Store in a cool, dry place, protected from light.

  • Use aseptically; discard single-dose ampoules after use.
