Description
GHRP-2 | Second-Generation GH Secretagogue — Research Grade
GHRP-2 (D-Ala-D-beta-Nal-Ala-Trp-D-Phe-Lys-NH2) is a synthetic hexapeptide GHS-R1a agonist with enhanced GH-stimulating potency compared to GHRP-6 and a reduced orexigenic signature. It is used as both a diagnostic tool and research compound in GH axis studies.
Mechanism of Action
- GHS-R1a agonism — potent pituitary GH release with reduced appetite stimulation vs GHRP-6
- Reduced ghrelin mimicry — lower affinity for peripheral ghrelin receptors limiting hunger side effects in research models
- ACTH/cortisol elevation — moderate increase in ACTH and cortisol at standard doses (less than GHRP-6)
- Pituitary reserve diagnostic — used in clinical GH stimulation testing protocols in endocrinology research
Research Areas
GHRP-2 is studied in GH deficiency diagnosis, body composition, metabolic research, and GHS pharmacology comparisons.

Dr. L. Petrov –
GHRP-2 at >99% purity confirmed by our LC-MS. In our ghrelin receptor binding assay it hit expected EC50 values within 5% of published references. COA was thorough. Rainbow Peptide is now our primary source for secretagogue research.
W. Chen –
GHRP-2 used in our GH secretagogue comparison study alongside GHRP-6 and Ipamorelin. All three sourced from Rainbow Peptide. Consistent purity across all lots. Results were clean and reproducible.
K. Nielsen –
Good GHRP-2. Purity confirmed at 98.5%. Arrived cold and in good condition. The COA shows full HPLC trace which we appreciate for documentation purposes. Will reorder.
