CJC-1295 and Ipamorelin: A Research Reference Guide
By Lemon Labs Research Desk · Updated June 29, 2026
In short
CJC-1295 and ipamorelin are two peptides studied together because they act on the growth-hormone axis through complementary mechanisms: CJC-1295 is a growth-hormone-releasing-hormone (GHRH) analog, while ipamorelin is a selective ghrelin-receptor (GHS-R) agonist. Both are research-use-only reference compounds.
Two complementary mechanisms
CJC-1295 is an analog of GHRH, the hormone that stimulates growth-hormone-releasing pathways in the pituitary. Ipamorelin is a selective agonist of the growth-hormone secretagogue receptor (the ghrelin receptor). Because GHRH analogs and secretagogues act on different receptors of the same axis, researchers study them as complementary probes.
Selectivity in research
Ipamorelin is frequently described in the literature as a selective secretagogue, a property researchers value for isolating ghrelin-receptor effects without engaging unrelated pathways. CJC-1295 with or without DAC (drug-affinity complex) is studied for differences in half-life in pharmacokinetic models.
Handling and quality
Both are supplied lyophilized; store cold, sealed, and protected from light, and reconstitute in the lab. Verify ≥99% HPLC purity and mass-spec identity on the lot COA.

Frequently asked
Why are CJC-1295 and ipamorelin studied together?
They act on the same growth-hormone axis through different receptors — CJC-1295 is a GHRH analog and ipamorelin is a selective ghrelin-receptor agonist — so they are used as complementary research probes.
What does "with or without DAC" mean for CJC-1295?
DAC (drug-affinity complex) is a modification studied for its effect on half-life. Researchers compare CJC-1295 with and without DAC in pharmacokinetic models.
Are these peptides for human use?
No. Both are research-use-only reference compounds, not for human or veterinary use.
