Ipamorelin: Research Profile, Dosages & Supplier Prices

Growth hormone secretagogue · Lyophilized vial · Also known as: NNC 26-0161, IPA

Ipamorelin is a growth hormone secretagogue compound with a molecular weight of 711.9 g/mol and a research half-life of approximately 2 hours in published pharmacokinetic research. Ipamorelin is a pentapeptide growth hormone secretagogue and ghrelin receptor (GHS-R1a) agonist. It is one of the most researched peptides in the GH axis category because published studies describe it as highly selective - stimulating growth hormone release in animal models without the significant cortisol, prolactin, or appetite effects seen with older secretagogues like GHRP-6.

What is Ipamorelin?

Research applications include growth hormone axis studies, body composition research models, and bone density investigation in animal subjects.

Ipamorelin is one of the most commonly blended peptides (frequently paired with CJC-1295 in research blends). Buyers should confirm whether a product is pure ipamorelin or a blend, and check that COAs are batch-specific rather than generic PDFs reused across products.

Mechanism of Action (Research Context)

Selective agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R1a), stimulating pulsatile GH release from the pituitary in research models without significant ACTH or cortisol elevation.

Ipamorelin FAQ

Published research describes ipamorelin as more selective - it stimulates GH release without the cortisol, prolactin, and hunger effects associated with GHRP-2 and GHRP-6 in comparative studies.
Look for 98%+ HPLC purity with mass spec confirmation of the 711.9 g/mol molecular weight on a batch-specific, third-party COA.
