Ipamorelin Research Guide: Selective GHRP & Growth Hormone Secretagogue Science

What Is Ipamorelin?

Ipamorelin is a synthetic pentapeptide that selectively agonizes the ghrelin receptor (GHS-R1a), driving pulsatile GH release from the anterior pituitary. It produces minimal cortisol, prolactin, or ACTH stimulation compared to earlier GHRPs.

Ipamorelin Molecular Profile
Property Value
Type GHRP (pentapeptide)
Sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2
Receptor GHS-R1a (ghrelin receptor)
Molecular Weight 711.9 g/mol
Key Feature High GH selectivity — minimal cortisol/prolactin
Growth Hormone Axis Research Tools
GHRH Analogues (CJC-1295, Sermorelin)
Mimic GHRH — act at GHRH receptors on pituitary somatotrophs. Upstream signal.
GHRPs (Ipamorelin)
Mimic ghrelin — act at GHS-R1a. Separate, complementary pathway.
Combination Research
Ipamorelin + CJC-1295 together produces more robust pulsatile GH release than either alone.
Selectivity Value
High GH selectivity allows isolation of GH-specific effects from pituitary hormone confounders.
GH Secretagogue Selectivity — Cortisol Stimulation (Lower = Better)
Ipamorelin — Cortisol stimulationMinimal — research preferred
GHRP-2 — Cortisol stimulationModerate confound
GHRP-6 — Cortisol stimulationSignificant confound
Ipamorelin Research Applications
Research Area Rationale Key Study Design
GH axis and somatotropic research Primary application Pulsatile GH measurement, IGF-1 downstream effects
Bone metabolism GH/IGF-1 regulate bone formation BMD and osteoblast markers in animal models
Muscle biology GH drives lean mass maintenance Satellite cell activation, protein synthesis
Aging / somatopause GH declines with age Restoration effects on aging biomarkers
