Testosterone Enanthate 250mg injection is a synthetic form of testosterone used to treat low testosterone levels in men, known as hypogonadism. It helps restore normal testosterone levels, which can improve symptoms like low energy, reduced muscle mass, and decreased libido. The injection is administered intramuscularly, usually every 1 to 4 weeks, and provides a sustained release of testosterone into the bloodstream. Common side effects include acne, fluid retention, and mood swings. Long-term use can also lead to more serious issues like liver damage and cardiovascular problems. Regular monitoring by a healthcare provider is essential to manage potential side effects and ensure effective treatment.
