What is Ipamorelin?
Ipamorelin (Selective GHSR-1a agonist (pentapeptide)) is a 5-amino acid synthetic pentapeptide. Highly selective ghrelin receptor (GHSR-1a) agonist stimulating GH release with minimal co-stimulation of cortisol, prolactin, or ACTH — the cleanest single-pathway GH secretagogue for research requiring isolated GHSR-1a activation without HPA axis confounds.
Research Applications
GHSR-1a Selectivity
Clean GH release without cortisol/prolactin/ACTH co-stimulation
HPA-Clean GH Research
Ideal control arm vs less selective GH secretagogues
Dual Pathway
Combined with CJC-1295 for GHRH-R + GHSR-1a synergistic GH release
Selectivity Comparison
vs GHRP-2 (moderate HPA) and GHRP-6 (full ghrelin-like profile)
Pulsatility

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial. Swirl gently until fully dissolved. Ipamorelin is a relatively small 5-amino acid pentapeptide and dissolves quickly. Solution should be clear and colourless.
How should this peptide be stored?
Store lyophilized at −20°C. Reconstituted solution: 2–8°C for up to 28 days. Ipamorelin is reasonably stable; avoid freeze-thaw cycling of reconstituted solution and protect from light.
What purity is this QSC compound and how is it verified?
QSC Ipamorelin is ≥99% HPLC pure with MS confirmation of the Aib-His-D-2-Nal-D-Phe-Lys-NH₂ sequence on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
