Growth-Hormone Research Peptides

Growth-hormone secretagogue research compounds from both receptor classes studied in pituitary release models: GHRH analogues that act at the GHRH receptor, and ghrelin-receptor (GHS-R1a) agonists that act at a separate site. Half-life is the main practical difference within each class, from minutes to several days. Supplied for laboratory research only.

What you will find here

Sermorelin is GHRH(1-29). CJC-1295 without DAC (Mod GRF 1-29) carries four amino-acid substitutions, including D-Ala2 for DPP-IV resistance. CJC-1295 with DAC carries a Drug Affinity Complex that binds albumin, extending its half-life to roughly a week. Tesamorelin is a GHRH(1-44) analogue with an N-terminal hexenoic-acid group. On the ghrelin-receptor side, ipamorelin is studied as a selective GHS-R1a agonist. GHRP-2 and GHRP-6 are hexapeptide GHS-R1a agonists. Hexarelin, a related hexapeptide, also binds the CD36 receptor. Because the two classes act at different receptors, published models often pair one GHRH analogue with one ghrelin-receptor agonist, and each product page states the strengths available.
