Testosterone Enanthate injection is an androgen and anabolic steroid medication primarily used for testosterone replacement therapy (TRT) in men with confirmed hypogonadism (low testosterone levels). It is a prescription-only, controlled substance administered either by intramuscular injection or, in certain formulations (e.g., Xyosted), via subcutaneous auto-injector. 

Key Information

• Primary Use: Treatment of male hypogonadism, delayed puberty in males, and certain types of metastatic breast cancer in women.

• Mechanism: It is an esterified form of testosterone that is slowly released from an oil depot after injection, restoring testosterone to normal physiological levels in the body.

• Administration: It is typically administered every 2 to 4 weeks via deep intramuscular injection into the gluteal muscle by a healthcare professional, although some self-administration options exist.

• Dosage: The typical dose for male hypogonadism is 50 mg to 400 mg every 2 to 4 weeks, adjusted based on the patient's condition and blood testosterone levels.
