Tesamorelin is a synthetic peptide that stimulates the release of growth hormone (GH) from the pituitary gland. It functions as a growth hormone-releasing hormone (GHRH) analog and is primarily used to treat lipodystrophy, particularly in people with HIV. Lipodystrophy is a condition that causes abnormal fat distribution, which can affect body image and physical health.
Tesamorelin helps reduce visceral fat (fat around the organs) by increasing natural growth hormone production, which supports fat metabolism. It is not generally used for general weight loss but is effective for targeted fat reduction in clinical cases. Tesamorelin is administered via injection and has specific guidelines for use due to possible side effects, which may include reactions at the injection site, increased blood sugar levels, and joint pain.
