Certificate of Analysis
Scientific Overview
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that acts as a ghrelin receptor (GHS-R1a) agonist. It was among the earliest synthetic growth hormone secretagogues developed for studying the ghrelin/growth hormone secretagogue receptor axis.

Research & Clinical Studies
GHRP-2 and GH Secretion
In clinical pharmacological studies, intravenous administration of GHRP-2 produced dose-dependent increases in circulating growth hormone levels mediated through the GHS-R1a receptor.
GHRP-2 Receptor Binding Studies
Radioligand binding assays characterized GHRP-2's affinity for the growth hormone secretagogue receptor. Studies demonstrated competitive binding with endogenous ghrelin at the receptor level.

Frequently Asked Questions
What is the purity of GHRP-2?
Our GHRP-2 is verified at 98.5% purity through independent third-party HPLC analysis. Each production batch undergoes rigorous quality testing, and a Certificate of Analysis (COA) is available for review in our COA Library.
How should I store this peptide?
Store refrigerated at 2–8°C. For extended storage, keep frozen at -20°C. Protect from light and moisture. Once reconstituted, solutions should be used promptly or stored frozen to maintain stability. Avoid repeated freeze-thaw cycles for best results.
Do you provide Certificates of Analysis?
Yes — every batch we produce is independently tested via HPLC and mass spectrometry to confirm identity and purity. COAs for all current batches are publicly accessible through our COA Library.
How is the product shipped?
All orders ship within 24 hours of purchase via USPS Priority Mail. Products are carefully sealed and packaged to ensure stability during transit. Orders over $150 qualify for free shipping. If you receive a damaged, defective, or incorrect product, please contact our support team with photos within 48 hours of delivery.
