Ipamorelin is a synthetic pentapeptide classified as a growth hormone secretagogue (GHS), specifically targeting ghrelin receptors to stimulate the pituitary gland's release of growth hormone (GH). Unlike earlier peptides like GHRP-6 or GHRP-2, Ipamorelin is highly selective, minimizing off-target effects such as cortisol or prolactin spikes. This specificity makes it a favored choice among bodybuilders seeking lean muscle gains without unwanted side effects.
