GHRP-2 (Growth Hormone Releasing Peptide-2)
Research-Grade Hexapeptide
Tagline: GH Secretion & Metabolic Research
Product Description
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide and ghrelin receptor (GHS-R1a) agonist that potently stimulates growth hormone (GH) release from the anterior pituitary.
Researchers use GHRP-2 in preclinical and in vitro studies to investigate GH axis physiology, IGF-1 production, metabolism, and hypothalamic regulation of appetite and energy balance.
For Laboratory and Scientific Research Use Only. Not for Human Consumption.
Why Researchers Choose GHRP-2
Potent GH Secretagogue: Stronger GH-releasing activity compared to GHRP-6.
Ghrelin Mimetic: Activates GHS-R1a, allowing study of hunger and metabolic signaling.
Synergistic Effects: Studied in combination with GHRH analogues like CJC-1295 to amplify GH pulses.
Endocrine Research Tool: Ideal for modeling GH/IGF-1 axis function.
Batch Verified: ≥98% purity, HPLC and MS confirmed.

Research Applications
Growth Hormone Axis Studies
GHRP-2 potently stimulates GH release independent of GHRH, making it valuable for pituitary responsiveness research [1].
IGF-1 Production & Protein Synthesis
Used to investigate hepatic IGF-1 production and its role in muscle protein metabolism [2].
Appetite & Energy Regulation
Activates hypothalamic ghrelin receptors, increasing food intake in animal models [3].
Combination Studies
Synergizes with GHRH analogues for enhanced pulsatile GH secretion, useful in endocrinology models [4].

Mechanism of Action (How GHRP-2 Works)
Ghrelin Receptor Agonism: Binds to GHS-R1a on pituitary somatotrophs and hypothalamic neurons, stimulating GH release [Bowers 1990].
Somatostatin Suppression: Reduces hypothalamic somatostatin output, allowing greater GH pulse amplitude [Bowers 1992].
Hunger Stimulation: Activates NPY/AgRP neurons in the arcuate nucleus, increasing appetite [Kojima 1999].
IGF-1 Pathway Activation: Increases circulating IGF-1, supporting anabolic signaling and tissue repair [Svensson 1998].
Synergistic with GHRH: Amplifies GH secretion when combined with GHRH analogues [Bowers 1992].
