Tesamorelin  is a peptide that binds to GHRH receptors to stimulate the pituitary gland into releasing growth hormone at a rate similar to the body’s naturally occurring GHRH traveling through the bloodstream. Once more growth hormone is released, it boosts metabolism and improves muscle growth, which helps to burn more calories and decrease body fat. The peptide can also help to increase insulin growth factor (IGF-1), which can help to lower glucose levels and further stimulate weight loss. As a result, Tesamorelin can help reduce visceral adipose tissue, leading to improved belly appearance, size, and waist circumference.
