What Is CJC-1295 + Ipamorelin?

Last reviewed: 17 August 2026

CJC-1295 + Ipamorelin lyophilised reference material vial

This pairing combines CJC-1295 — a modified growth-hormone-releasing-hormone (GHRH) analogue — with ipamorelin, a selective pentapeptide agonist at the ghrelin receptor (GHS-R1a). The two act on different upstream inputs to the same pituitary axis, which is why the research literature examines them as a pair.

How are these compounds classified?

CJC-1295 is a GHRH(1-29) analogue with substitutions that resist enzymatic degradation; the 'no DAC' form omits the drug-affinity-complex modification and therefore has a shorter studied half-life. Ipamorelin is classed as a growth-hormone secretagogue, notable in the literature for its selectivity relative to earlier GHRPs.

How is the mechanism studied?

  • GHRH receptor signalling on pituitary somatotrophs, studied for effects on GH pulse amplitude.
  • GHS-R1a activation, studied as a separate secretagogue input to the same cells.
  • Downstream IGF-1 readouts used as a study endpoint in animal models.

Descriptions of pulsatility and IGF-1 endpoints summarise study models. They are not human-use claims.

What kind of research exists?

GHRH analogue pharmacology is well established; ipamorelin has a defined receptor-selectivity literature from the late 1990s onward. Research on the specific combination is thinner and largely mechanistic, so combination-specific conclusions should be read cautiously.

What is it studied alongside?

Tesamorelin and sermorelin (other GHRH-family analogues), and GHRP-2 / GHRP-6 as earlier-generation secretagogues.

How does Neo Labs supply and handle it?

Supplied as a co-lyophilised research blend, third-party tested with a batch COA. Cold, dark storage.

Primary literature

We link live PubMed searches rather than a fixed citation list, so you always land on the current indexed record — including papers published after this page was reviewed.

The indexed literature for these compounds is predominantly preclinical. Citations are provided for scientific reference and do not imply any human-use indication.
