Ipamorelin

Ipamorelin is a synthetic pentapeptide that functions as a selective growth hormone secretagogue, meaning it stimulates the release of growth hormone by activating ghrelin (GHS-R1a) receptors in the pituitary gland. It is designed to increase growth hormone levels in a more targeted manner compared to earlier secretagogues, with minimal impact on other hormones such as cortisol or prolactin in research settings.

In scientific studies, ipamorelin is investigated for its potential roles in promoting tissue repair, supporting muscle recovery, enhancing fat metabolism, and influencing body composition through growth hormone–mediated pathways. It is also studied in the context of aging biology, sleep regulation, and regenerative processes due to its effects on endogenous growth hormone secretion.

Ipamorelin is used in laboratory and preclinical research to better understand growth hormone signaling, endocrine regulation, and downstream metabolic effects associated with controlled stimulation of the growth hormone axis.
