Active ingredient: Testosterone enanthate (250 mg/ml).
Excipients:
Phenylcarbenol (phenylcarbinol) — often used as a preservative or local anesthetic.
Benzyl benzoate — a solvent that ensures the stability of the solution.
Peanut or peach oil — the injection base (important for patients with peanut allergies).
2. Pharmacodynamics (Mechanism of action)
This drug is a depot form of testosterone. Enanthate is an ester that provides prolonged action. After intramuscular injection, it is slowly released from the oil depot.
Key effects of testosterone:
Androgenic: Development of the genitals, secondary sexual characteristics (hair growth, deepening of the voice), libido.
Anabolic: Increased protein synthesis, retention of nitrogen, potassium, and phosphorus, increased muscle mass.
Hematopoiesis: Stimulation of erythropoietin production (increase in red blood cell production).
Pituitary: Inhibits the secretion of gonadotropins (LH and FSH) via a feedback mechanism, leading to suppression of spermatogenesis (temporary or permanent, depending on the duration of therapy).
Bone growth: Accelerates skeletal maturation and may lead to premature closure of the epiphyseal growth plates (important for adolescents).
3. Important notes for use
Based on standard medical protocols (e.g., instructions for Testosterone Enanthate or Testenate), this dosage form is generally intended for intramuscular (deep muscle) injection.
Critical points to monitor:
Allergy: Since the product contains peanut oil, it is contraindicated in patients with allergies to peanuts or soybeans.
Monitoring: Due to suppression of spermatogenesis and effects on the prostate gland, PSA (prostate-specific antigen) levels and prostate function should be monitored before and during therapy.
Contraindications (standard): Prostate or breast cancer in men, hypercalcemia, severe liver/kidney/heart disease in the decompensated stage, childhood (under 18 years), hypersensitivity to the components.
