Ipamorelin — Selective GH Secretagogue for Targeted Research
Ipamorelin is a synthetic pentapeptide GHS-R1a agonist distinguished by exceptional selectivity — stimulates GH without affecting cortisol, prolactin, or ACTH (Raun et al., pharmaceutical-grade Journal of Endocrinology, 1998). The most specific GHS-R1a agonist available.
Mechanism of Action
Ipamorelin activates GHS-R1a with high affinity via PLC signaling. Minimal interaction with other hormone pathways. No tachyphylaxis over extended dosing. Clean pharmacological profile makes it the preferred secretagogue for isolated GH axis research.
Key Research Areas
- Selective GH Release: Robust GH release without cortisol, ACTH, or prolactin increases — study GH-specific effects cleanly.
- Synergistic Studies: Combined with CJC-1295 for complementary GHRH + GHS-R amplification exceeding either alone.
- GHS-R1a Pharmacology: Reference compound for ghrelin receptor selectivity, biased agonism, and structural determinants.
- Bone Metabolism: Preclinical effects on osteoblast differentiation and BMD via direct GHS-R1a and indirect GH/IGF-1 signaling.
