GHRH/GH-Axis
Ipamorelin Research Peptide
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It is one of the most studied peptides in the GH secretagogue class for its selectivity profile.

Ipamorelin in Research
Ipamorelin is a synthetic pentapeptide and selective ghrelin-receptor (GHS-R1a) agonist — one of the most-cited compounds in growth-hormone-secretagogue research. Its reputation for selectivity comes from animal studies reporting GH release without meaningful effects on cortisol or prolactin at the doses studied, a profile earlier secretagogues lacked.
Supplied lyophilized at 5mg per vial, ≥99% purity, with independent HPLC and MS verification on every lot. It is commonly studied alongside GHRH-receptor analogs such as CJC-1295 No DAC in complementary-pathway designs.
Research Overview
- Investigated for selective GH release without affecting cortisol or prolactin
- Studied for ghrelin receptor (GHS-R1a) agonism
- Research into dose-dependent GH release patterns
- Explored in combination with GHRH analogs in animal models
- Preclinical bone density and body composition studies
Quality & Testing
Every Ipamorelin batch is verified by independent third-party HPLC and mass-spectrometry testing, with a batch-specific certificate of analysis available on the COA page.
Laboratory Handling & Storage
Lyophilized peptides are supplied as a freeze-dried powder and are most stable stored cold (2–8°C), protected from light and moisture, in the original sealed vial. Under these conditions the research literature generally reports multi-year integrity for dry peptide material.
Once reconstituted in a laboratory setting, solutions are typically stored refrigerated and used within the window appropriate to the diluent and compound; repeated freeze–thaw cycles are avoided because they can promote aggregation. See our research overview on reconstitution and lyophilization for the underlying formulation science.
Frequently Asked Questions
What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH₂) studied as a selective ghrelin-receptor agonist in growth-hormone-secretagogue research.
What does 'selective' mean in Ipamorelin research?
In the animal literature, Ipamorelin stimulated GH release with little effect on cortisol, prolactin, or ACTH relative to earlier secretagogues — making it a cleaner tool compound for isolating GHS-R1a signaling.
Is Ipamorelin for human use?
No. Ipamorelin is a research compound for laboratory use only — not an approved therapeutic, and prohibited in sport by WADA.
