Albert's Verdict
Ipamorelin is the cleanest GHS-R1a agonist in the catalog — highly selective for pituitary release with minimal cortisol or prolactin signal. That selectivity is exactly what you want when isolating ghrelin-receptor mechanisms.

Product Description
Ipamorelin is a selective growth-hormone releasing peptide (GHRP) that stimulates natural pulsatile GH release from the pituitary gland. Its selectivity is what sets it apart — unlike older GHRPs, Ipamorelin does not meaningfully elevate cortisol, prolactin, or hunger, giving it the cleanest side-effect profile of any GH secretagogue.
Extensively researched for body composition, recovery, sleep quality, bone growth, and anti-aging applications. Most commonly paired with a GHRH such as CJC-1295 (No DAC) for a stronger, more synergistic GH pulse. For research use only. Not for human or veterinary consumption.

Research FAQ — Ipamorelin
Frequently asked questions about this compound for laboratory researchers.
What is Ipamorelin?+
Ipamorelin is a selective pentapeptide GHS-R (ghrelin-receptor) agonist. The 1998 publication describing its discovery characterized it as a selective growth hormone secretagogue in research models, with reduced reported effects on cortisol and prolaktin.
Cited: PMID 9849822
How is Ipamorelin different from GHRP-2 or GHRP-6 in research literature?+
Published comparative literature highlights Ipamorelin's selectivity for GHS-R and its reduced effect on other pituitary hormones relative to GHRP-2 and GHRP-6 in animal research models.
Cited: PMID 18430761
Is Ipamorelin commonly paired with CJC-1295 No DAC in research protocols?+
Yes — research literature describes combined administration as a way to investigate complementary GH-release pathways (GHRH-receptor + GHS-R). BioInfinity offers a pre-blended CJC-1295 + Ipamorelin vial for research convenience.
How should Ipamorelin be stored?+
Lyophilized at −20 °C protected from light; reconstituted held at 2–8 °C and typically used within 30 days. Refer to the product COA.

Research summary
Ipamorelin — clinical & mechanistic profile
Ipamorelin is the first GHRP with GHRH-like selectivity, binding GHSR-1a (ghrelin receptor) to stimulate pulsatile GH release with EC50 = 1.3 nmol/L and Emax = 85% comparable to GHRP-6, but without ACTH/cortisol elevation even at >200-fold above GH ED50. Lower plasma clearance (5-fold slower than GHRP-6) with ~50% nasal bioavailability.

Studied applications
- •Exceptional selectivity: no significant ACTH/cortisol elevation at >200-fold GH ED50, mirroring GHRH selectivity
- •GHRP-6 equivalent potency: EC50 = 1.3 ± 0.4 nmol/L, Emax = 85 ± 5% in rat pituitary; ED50 = 80 nmol/kg in vivo
- •Pulsatile GH release: dose-dependent peaks at 15-60 min, baseline by 180 min; synergistic with GHRH
- •Superior pharmacokinetics: 5-fold lower plasma clearance than GHRP-6, ~50% nasal bioavailability
- •GI-independent action: gastrectomy reduces GHRP-6 GH release 60-70%, suggesting gastric ghrelin component
Mechanisms of action
- •GHSR-1a agonism: selectively binds ghrelin receptor, confirmed via GHRP antagonist pharmacology (not GHRH pathway)
- •Pituitary somatotroph activation: directly stimulates GH-producing cells via Gq-protein/calcium signaling
- •Hypothalamic modulation: may upregulate GHRH mRNA in arcuate nucleus, downregulate somatostatin in periventricular nucleus
- •Calcium influx: triggers intracellular Ca2+ signaling from IP3-mediated stores for GH vesicle release
- •Pathway selectivity: minimal cross-talk to ACTH-releasing or prolactin-releasing pathways
- •Synergistic with GHRH: amplifies GH pulse through complementary cAMP (GHRH) and Ca2+ (ipamorelin) pathways
Research constraints & safety notes
- •Not approved for human therapeutic use—research compound only
- •Clinical development for postoperative ileus discontinued
- •Short half-life (~2 hours) requires multiple daily administrations
- •GH elevation may affect glucose metabolism
- •Quality and purity of research compounds varies between sources
