A selective growth-hormone secretagogue researched for stimulating pituitary GH release with minimal effect on other hormones.
Ipamorelin is a pentapeptide that acts as a selective agonist at the ghrelin/growth-hormone secretagogue receptor. Research highlights its stimulation of pituitary growth-hormone release with comparatively little impact on cortisol or prolactin, distinguishing it from earlier secretagogues.
It is commonly studied alongside GHRH analogs to model combined pituitary signalling. It is used strictly as a research compound.
Studied for selective ghrelin-receptor agonism with minimal off-target hormone effects.
Researched for stimulating pulsatile pituitary growth-hormone secretion in model systems.
Examined for limited impact on cortisol and prolactin compared with other secretagogues.
Investigated for downstream IGF-1 and growth-axis effects in preclinical research.
Bring the vial (10 mg) and bacteriostatic water to room temperature.
Add bacteriostatic water slowly along the glass wall — the volume you add sets the concentration.
Swirl gently (do not shake) until fully clear, then refrigerate at 2–8 °C.
Widely studied pairing combining selective secretagogue action with GHRH stimulation.
Compared in research for differences in selectivity and appetite-related signalling.

Research indicates it stimulates growth-hormone release through the ghrelin receptor with comparatively little effect on cortisol and prolactin, making it useful for studying GH signalling in isolation.
Both are secretagogues, but research notes Ipamorelin has greater hormone selectivity and less appetite-related signalling than GHRP-6 in comparative model systems.
Because the two act on different receptors, researchers study combinations such as with CJC-1295 to model potential synergistic effects on pituitary growth-hormone release.
