Why ipamorelin is called a selective GH secretagogue, how it differs from CJC-1295, and what to check when sourcing it in the UK. For in-vitro research use only.
Ipamorelin is often described as one of the "cleaner" growth-hormone secretagogues studied in research, and that reputation is worth unpacking. This guide explains what it is, why it's frequently studied alongside CJC-1295, and what to look for when sourcing it in the UK — for in-vitro research only.
A selective secretagogue
Ipamorelin is a synthetic pentapeptide that acts on the ghrelin receptor (also called the GH-secretagogue receptor). What earned it attention in the literature is its selectivity: in research models it stimulates the GH pathway with relatively little cross-talk into other endocrine signals such as cortisol or prolactin. That makes it a comparatively narrow, predictable tool for studying one pathway in isolation.
UKPeptides supplies ipamorelin at ≥99% HPLC purity, with a batch-specific Certificate of Analysis on every order.
Why it's studied with CJC-1295
Ipamorelin and CJC-1295 (No DAC) act on two different receptors — the ghrelin receptor and the GHRH receptor — so a lot of research looks at them together to compare or combine those two arms of GH-pathway signalling. They're separate compounds with separate mechanisms, which is exactly why they're interesting to study side by side rather than as a single thing.
Typical research areas include:
- Ghrelin-receptor signalling in endocrine models
- Growth-hormone-secretagogue pathway studies
- Comparative work with GHRH analogues

Purity and identity
Short peptides like ipamorelin are easier to synthesise cleanly than the long tri-agonists, but that doesn't make verification optional — you still want to see the HPLC purity figure and the mass-spec identity confirmation before trusting a result to it. Both live on the Certificate of Analysis, and every batch we ship is tested at an independent accredited lab with the matching COA included.
Handling
Ipamorelin arrives lyophilised and reconstitutes easily in bacteriostatic water. Add the solvent gently, let it dissolve without shaking, and keep the reconstituted solution cold and out of the light. Our reconstitution guide has the full method.
Sourcing in the UK
The checklist is simple: ≥99% HPLC purity, a batch-specific COA, cold-chain dispatch, and research-use-only labelling.
