Overview

Ipamorelin is a synthetic pentapeptide that acts as a selective growth hormone secretagogue receptor (GHSR) agonist. It was developed to stimulate growth hormone release while minimizing effects on cortisol and prolactin, distinguishing it from other GH secretagogues like GHRP-6.

Research has explored its potential in growth hormone deficiency, bone health, and metabolic applications.

Mechanism of Action

Ipamorelin selectively binds to the ghrelin/growth hormone secretagogue receptor (GHSR) in the pituitary gland, stimulating growth hormone release in a dose-dependent manner. Unlike other GH secretagogues, it does not significantly affect ACTH, cortisol, or prolactin levels, suggesting higher selectivity for GH pathways.

Research Findings

Limited Human Data

Phase II clinical trials have been conducted for post-surgical ileus recovery. Animal studies demonstrate GH release without cortisol/prolactin elevation. Some studies suggest beneficial effects on bone mineral density. Research on metabolic effects is ongoing. No peptide has been approved as a standalone GH secretagogue for general use.

Risks & Safety Concerns

Potential risks include disruption of natural GH pulsatility, headache, lightheadedness, and water retention. Long-term safety of chronic GH elevation is not established in this context. Concerns about effects on glucose metabolism and insulin sensitivity. Quality of research-grade products varies.

Regulatory & Legal Status

Research Only

Not approved by FDA for any indication. Available as a research peptide. Sometimes prescribed off-label by anti-aging clinics. Listed on WADA prohibited list.
