GHRP-2 has been studied extensively in preclinical models investigating GHS-R agonism, growth hormone secretion, and hypothalamic-pituitary signaling. It is one of the most potent synthetic GHRPs characterized in the literature and is frequently used as a reference standard in GH secretagogue research. Studies have examined its receptor binding affinity, growth hormone pulse amplitude, and endocrine response profiles including cortisol modulation in animal models.

Handling Information
Handle GHRP-2 under standard laboratory conditions with appropriate PPE. Reconstitute carefully and avoid repeated freeze-thaw cycles once reconstituted. This compound is intended for use by qualified research professionals only.
Storage Requirements
- Long-term (lyophilized): Store at -20°C, protected from light and moisture
- Short-term (reconstituted): Store at 4°C; use within 28 days
- Keep in original sealed vial until point of use
How should I store this peptide?+
Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.
What should I reconstitute it with?+
Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.
How quickly do orders ship?+
Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.
Is the COA verified independently?+
Yes. Every product is tested by HPLC for purity (target COA-verified purity) and mass spectrometry for molecular identity before release. The COA is generated from the actual test data, not a generic template.
Can I get bulk or institutional pricing?+
Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
