Growth Hormone & IGF · Ghrelin-receptor agonist research
Scientific Product Dossier
Ipamorelin is a short peptide studied mainly for growth-hormone release. It acts at the receptor used by ghrelin, a natural hormone. Healthy-volunteer research measured a brief growth-hormone response. Researchers also tested a clinical formulation in people recovering from bowel surgery. The main meal-tolerance comparison did not show a statistically significant benefit over placebo. A hormone response and a patient benefit are therefore different outcomes. Other routes and long-term effects need their own evidence; NHD material is supplied for laboratory research.
Shared values below are consolidated from the current catalog record. They are not independent verification or lot results; request the applicable product specification and ask which lot records are available before ordering.

Reported research findings
Reported outcomes are paired with their experimental model and evidence boundary.
117 enrolled; 114 analyzed. Median time to a tolerated meal was 25.3 versus 32.6 hours, p=0.15.
Intravenous inpatient protocol after bowel resection; cannot be generalized to other routes.
Read the primary studyFDA flags immunogenicity, aggregation/impurity and unnatural-amino-acid characterization concerns, with insufficient safety data for some routes.
FDA assessment describes evidence gaps, not a test of this catalog lot.
Read the primary studyFive infusion-rate levels were studied with eight healthy men at each level. The reported terminal half-life was about 2 hours; GH peaked at approximately 0.67 hours.
This was an intravenous pharmacokinetic study, not a trial of long-term body-composition outcomes. Subcutaneous kinetics cannot be assumed from these results.
Read the primary study117 patients were enrolled and 114 entered the safety and modified intention-to-treat populations. Median time to the first tolerated meal was 25.3 hours with ipamorelin and 32.6 hours with placebo (p=0.15).
The primary and secondary efficacy analyses did not show significant between-group differences. The study concerned hospital patients after bowel resection.

Concise answers for researchers comparing identity, evidence and catalog variants.
Healthy-volunteer work showed a reliable short pulse of growth hormone with fast clearance from the body. The larger test, in patients after bowel surgery, found the median time to tolerating a meal was shorter, but the difference was not statistically significant. So the hormone effect is well documented, while a patient benefit was not proven. Findings from one route or group should not be assumed to apply elsewhere.
Regulatory reviewers have noted that safety data are incomplete for some routes. They also raised concerns about immune reactions, clumping and impurities, partly because the peptide contains an unnatural amino acid. These are evidence gaps, not demonstrated harms, but they mean findings from one route or preparation should not be assumed to apply to another without direct study.
No. The 25.3 versus 32.6 hour median comparison had p=0.15.
No. Exposure route, clinical setting and formulation are part of the evidence and cannot be transferred automatically.
Family-level identifiers organize the catalog. Confirm the supplied form, identity and release criteria using the applicable product specification and ask which lot records are available.
A lot-specific COA, product specification sheet and analytical method summary can be requested where applicable.
Store at -20 °C, protected from light and moisture. After reconstitution, aliquot and avoid repeated freeze-thaw cycles. Confirm the applicable storage statement on the product-specific specification and lot documentation.
