Ipamorelin FAQ: Your Questions Answered
The questions below are the ones that come up specifically about Ipamorelin, rather than general peptide questions that apply to everything.
Overview
People ask why it is called selective, how it differs from GHRP-6 and GHRP-2, why it pairs with CJC-1295, and whether it needs darkness (no).
What Ipamorelin actually is
A small five-part peptide that gently tells the body to release growth hormone while leaving stress and hunger signals mostly alone — which is why it is the go-to clean GH research peptide. Often paired with CJC-1295.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥97% purity, with a Certificate of Analysis on every order. Ships across Canada.

Ipamorelin — common questions
Why is Ipamorelin called selective?
Earlier growth-hormone-releasing peptides also nudged cortisol, prolactin and appetite pathways. Ipamorelin was characterised as releasing GH while leaving those largely untouched, which is why it is treated as the clean reference secretagogue in research.
How does it differ from GHRP-6 or GHRP-2?
All act at the ghrelin receptor, but GHRP-6 and GHRP-2 carry more off-target hormonal activity. Ipamorelin was engineered specifically to minimise that.
Why pair it with CJC-1295?
CJC-1295 works through the GHRH receptor and Ipamorelin through the ghrelin receptor. Combining them lets researchers study complementary, non-overlapping release pathways.
Does it contain oxidation-prone residues?
No methionine, cysteine or tryptophan — which is why it does not need the light protection some other peptides require and holds up comparatively well in solution.
What Ipamorelin is studied for
Studied as a selective GHS-R agonist that releases GH with little effect on cortisol, prolactin or ACTH — the feature that distinguishes it from earlier GHRPs.
Examined for the shape and timing of growth-hormone release in research models.
Frequently combined with GHRH analogues such as CJC-1295 to study two GH-release pathways at once.
