Testosterone Cypionate 250mg injection is a form of synthetic testosterone used to treat low testosterone levels in men, a condition known as hypogonadism. It helps alleviate symptoms like low energy, reduced muscle mass, and decreased libido by restoring normal testosterone levels in the body. The injection is typically administered intramuscularly every 1 to 4 weeks, providing a long-lasting effect due to its extended release. Common side effects include acne, fluid retention, and mood changes, while more serious risks can include liver damage and cardiovascular issues. Regular monitoring by a healthcare provider is important to manage side effects and ensure effective treatment.
