Growth hormone secretagogues are peptides that act on the body's own signaling to influence growth hormone release. The family includes GHRH analogs and ghrelin-mimetic GHRPs, and its members are studied in research and supplied for research use only.
The two main groups
The family splits into two complementary groups:
- GHRH analogs: peptides modeled on growth-hormone-releasing hormone, such as Sermorelin, CJC-1295, and Tesamorelin.
- GHRPs (ghrelin-mimetics): peptides that mimic ghrelin, such as Ipamorelin.

Why they are often combined
Because the two groups act through different mechanisms, they are complementary. That is why a GHRH analog and a GHRP, such as CJC-1295 and Ipamorelin, are so often studied together. As research compounds, all are supplied for research use only.
Browse research-grade peptides
Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
What to look for
Whichever secretagogue you study, a research-grade compound should ship with a batch-specific certificate of analysis documenting purity and identity.
Key takeaways
- Growth hormone secretagogues act on the body's own signaling.
- They split into GHRH analogs and ghrelin-mimetic GHRPs.
- Examples: Sermorelin, CJC-1295, Tesamorelin, Ipamorelin.
- All are research compounds, supplied for research use only.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
