Testosterone enanthate is an injectable form of the primary male sex hormone testosterone. It is an androgen and anabolic steroid that is used medically to treat low testosterone levels in men. Some key details about testosterone enanthate:
What is it used for?
- Testosterone replacement therapy in men with clinically low testosterone levels (a condition known as hypogonadism)
- Gender transition for transgender men
- Occasional off-label use to treat some autoimmune diseases
How does it work? When injected into muscle tissue, testosterone enanthate absorbs slowly into the bloodstream to provide higher sustained testosterone levels. This helps supplement the body's own natural testosterone production.
What are the side effects? Possible side effects include acne/oily skin, breast swelling, mood changes/irritability, water retention, testicular atrophy, and insomnia. However, proper clinical monitoring and dosage adjustment can help minimize side effects.
Is it legal? Yes, testosterone enanthate is legal to possess and use in most countries when prescribed for legitimate medical conditions such as clinically diagnosed low testosterone. Some athletes and bodybuilders misuse it illegally as a performance-enhancing drug.
