Ipamorelin is a synthetic pentapeptide that acts as a selective growth hormone secretagogue, activating the ghrelin/growth hormone secretagogue receptor. It is frequently studied and discussed alongside GHRH analogs such as CJC-1295 for its comparatively selective GH-release profile.
Research-grade Ipamorelin is typically supplied as a lyophilized powder in sealed vials, commonly at 2mg or 5mg strengths, intended for laboratory reconstitution and research use only.
Ipamorelin binds the ghrelin receptor (GHS-R1a) in the pituitary and hypothalamus, stimulating pulsatile growth hormone release. Research has focused on its selectivity — earlier-generation GH secretagogues also raised cortisol and prolactin, while Ipamorelin has been studied for producing a more targeted GH response with comparatively less effect on those other hormones.
Ipamorelin is studied for its ability to stimulate endogenous GH pulses without the broader hormonal side effects associated with older secretagogues, making it a frequent subject of comparative GHS-R research.
Because GH signaling is linked to lipolysis and lean-tissue metabolism, Ipamorelin is often studied in combination with GHRH analogs in research examining body-composition outcomes in animal and early clinical models.
Ipamorelin is not FDA-approved and has not been evaluated in large-scale human trials as a standalone therapeutic. Reported research and anecdotal concerns include injection-site reactions, transient flushing, and — because it acts on GH pathways — theoretical concerns around long-term GH-axis effects that have not been fully characterized in humans.
Doses used in preclinical and small clinical research studies vary by study design and are not established as a standardized human protocol. No FDA-approved human dosage exists for Ipamorelin.
Compound X does not sell Ipamorelin directly. We provide independent research, comparisons and vendor links — see the vendor comparison table above for current US, UK, Canada and Australia options.
Ipamorelin research is indexed on PubMed under search terms such as "Ipamorelin growth hormone secretagogue" and "ghrelin receptor agonist pituitary."
