Ipamorelin is a synthetic peptide that acts as a growth hormone secretagogue, meaning it stimulates the release of growth hormone from the pituitary gland. It is often used in the field of anti-aging and performance enhancement due to its ability to promote muscle growth, reduce body fat, and improve recovery times. Unlike some other growth hormone-releasing peptides, Ipamorelin has a selective action that minimizes potential side effects such as increased appetite and elevated cortisol or prolactin levels.
