Growth Hormone Secretagogues
Growth hormone secretagogues are research peptides studied for their interaction with the pathways that regulate growth hormone release. The category includes growth hormone-releasing hormone (GHRH) analogs such as Sermorelin, Tesamorelin, and CJC-1295, as well as ghrelin-receptor agonists such as Ipamorelin.
These molecules are used in preclinical research to examine GHRH- and ghrelin-receptor signaling and the broader growth hormone/IGF-1 axis. All peptides in this collection are lyophilized, 99%+ pure, and third-party tested by HPLC and mass spectrometry. For laboratory and research use only.

About growth hormone secretagogue research peptides
Growth hormone release is regulated through two receptor routes that researchers study separately and together: the GHRH receptor, targeted by growth hormone-releasing hormone analogs, and the ghrelin receptor (GHS-R1a), targeted by ghrelin mimetics. Further downstream the axis runs through IGF-1. This category has peptides for each of those points.
GHRH analogs
- Sermorelin (5mg, 10mg): the first 29 amino acids of native GHRH. Sermorelin research overview.
- Tesamorelin (5mg, 10mg, 20mg): a full-length GHRH analog stabilized by an N-terminal modification.
- CJC-1295 with DAC and CJC-1295 without DAC (5mg): modified GHRH(1-29) sequences. The DAC version carries a drug affinity complex that binds albumin and extends half-life; the version without DAC is also called Mod GRF 1-29.
Ghrelin receptor agonists
- Ipamorelin (5mg, 10mg): a selective pentapeptide agonist at the ghrelin receptor. Ipamorelin and CJC-1295 research overview.
Combinations and the IGF-1 end of the axis
- CJC-1295 + Ipamorelin and Tesamorelin + Ipamorelin pair a GHRH analog with a ghrelin receptor agonist in one vial.
- IGF-1 LR3 (0.1mg, 1mg): a long-acting IGF-1 analog whose substitution and N-terminal extension reduce binding-protein affinity.
The main routes are compared in Sermorelin vs Ipamorelin vs CJC-1295.
Frequently asked questions
What is the difference between CJC-1295 with and without DAC?
The drug affinity complex (DAC) lets the peptide bind albumin, which extends its half-life in research models. The version without DAC, also called Mod GRF 1-29, is shorter-acting.
Why are GHRH analogs and ghrelin agonists paired?
They act on different receptors in the same axis, so combining them lets researchers compare joint and separate receptor activation.
