Growth Hormone Research Peptides

Growth hormone research peptides

Growth hormone secretagogues are studied for how they trigger the pituitary's own GH release. They fall into two families: GHRH analogues — Sermorelin, Tesamorelin, CJC-1295 with DAC and Mod GRF 1-29 (CJC-1295 no DAC) — and ghrelin-receptor agonists (GHRPs) — Ipamorelin, GHRP-2, GHRP-6 and Hexarelin.

Because the two families act on different receptors, researchers often study them together; we stock the CJC-1295 + Ipamorelin blend and the Tesamorelin + Ipamorelin blend. The CJC-1295 / Ipamorelin evidence brief and GH peptide comparison explain the differences in half-life and selectivity.

Buying growth hormone research peptides

Each product lists its HPLC purity specification (≥98% or higher). Where a CertikLabs certificate of analysis (COA) is available for a strength and lot, it is linked from that product page with HPLC purity, LC-MS identity, and concentration results. Compare the precise GHRH or GHRP identity, modification, strength and available report before ordering. For an evidence-based purchase review, use the research peptide supplier checklist, learn how peptide lab verification works, and confirm that any available report matches the ordered product, strength and lot. All compounds are supplied lyophilized, strictly for in-vitro laboratory research. They are not drugs, supplements or cosmetics and are not for human or veterinary use — see Research Use Only.

Frequently asked questions

What is the difference between CJC-1295 with DAC and without DAC?

CJC-1295 with DAC carries a drug affinity complex that binds albumin and greatly extends its half-life; Mod GRF 1-29 (no DAC) has a short half-life closer to native GHRH.

Is Ipamorelin selective?

In published studies Ipamorelin is described as a selective ghrelin-receptor agonist with little effect on cortisol or prolactin compared with GHRP-2 and GHRP-6.
