Growth Hormone Axis Research Peptides

Growth hormone axis peptides in this catalog fall into two structurally distinct classes: GHRH analogs and growth-hormone secretagogues. Because these are commonly conflated in vendor copy, our COAs document identity method (LC-MS or HRMS) alongside the assay purity — identity is separated from potency in every report. The purity value shown on each product page is the numeric result printed on the linked batch COA, retrieved from our parser rather than paraphrased.

Class chemistry

GHRH analogs (tesamorelin, sermorelin, CJC-1295) and GHRPs / growth-hormone secretagogues (ipamorelin, hexarelin) act on distinct receptors upstream of the somatotropic axis. They are structurally and pharmacologically separate classes despite frequent co-study.
