Tesamorelin is a growth hormone-releasing hormone (GHRH) analog that has been shown to increase the body’s own natural growth hormone and IGF-1 levels. It promotes visceral (abdominal) fat loss and muscle growth by stimulating the liver to release insulin-like growth factor-1 (IGF-1).Tesamorelin stimulates the pituitary gland in your brain to increase your body’s own natural production of growth hormone.Tesamorelin significantly reduces abdominal fat and improves physical fitness with fewer side effects than Human Growth Hormone (HGH) itself. It is also an effective treatment to boost metabolism, improve insulin resistance and brain health. The effects on abdominal fat reduction can usually be observed within a few months of consistent use. Tesamorelin is currently the most effective HGH releasing hormone peptide available.
