Growth hormone secretagogue research
The GH-axis research area - GHRH analogues and ghrelin-receptor agonists studied for their effect on pulsatile growth-hormone secretion.
Growth-hormone secretagogue research studies two complementary peptide classes: GHRH analogues (sermorelin, CJC-1295, tesamorelin) that act on the growth-hormone-releasing-hormone receptor, and ghrelin-receptor agonists / GHRPs (ipamorelin, GHRP-2, GHRP-6, hexarelin) that act on the GHS-R. The two classes are often studied in combination for their effect on pulsatile GH release in preclinical models.
This hub groups the research compounds New-U supplies in this area alongside the on-site guides that summarise the published science.
3 of the 8 compounds in this area have a current published Certificate of Analysis from an independent laboratory, linked on its card below and listed at /coa.

Frequently asked questions
What is a growth hormone secretagogue?
A growth hormone secretagogue is a compound studied for its ability to stimulate the secretion of growth hormone. Research distinguishes GHRH analogues (which act on the GHRH receptor) from ghrelin-receptor agonists / GHRPs (which act on the GHS-R). New-U supplies these compounds for laboratory research use only.
Why are GHRH analogues and GHRPs studied together?
In the published literature the two classes act on different receptors and are frequently studied in combination (e.g. CJC-1295 with ipamorelin) because their mechanisms are complementary in models of pulsatile growth-hormone release.
How is purity verified?
Released batches are analysed by independent laboratories (Janoshik Analytical and Freedom Diagnostics) by RP-HPLC for purity and mass spectrometry for identity. Every released sale batch must pass independent verification before it is offered for sale. Published Certificates of Analysis are listed per compound at /coa. In this area, 3 of the 8 compounds have a current published certificate.
