GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that acts as a potent agonist at the ghrelin receptor (GHS-R1a). In laboratory research, it stimulates GH release from the pituitary and is used to study the GH secretagogue system, appetite signaling, and metabolic regulation.
GHRP-2 produces a strong GH pulse in research models with moderate effects on cortisol and prolactin release. Compared to GHRP-6, it has less appetite-stimulating effect. Compared to Ipamorelin, it has broader receptor activity and typically produces a stronger GH response, making it useful for studying GH axis physiology.
GHRP-2 lyophilized powder should be stored at -20°C, protected from light and moisture. Under these conditions it remains stable for 24+ months. AscendLabz ships all peptides in appropriate packaging to maintain integrity during transit.
RESEARCH USE ONLY: All products sold by AscendLabz are strictly for laboratory research purposes only. Not for human consumption. Not for veterinary use. Must be handled by qualified research professionals in a controlled laboratory environment.
GHRP-2 is a synthetic hexapeptide growth-hormone-releasing peptide acting on the ghrelin receptor (GHS-R1a) studied as part of the growth hormone secretagogue category. It is investigated in pre-clinical and in-vitro research models for its activity on GHS-R1a receptor signaling and pituitary somatotroph activation studied in vitro. The compound is supplied as a lyophilized powder of ≥99% HPLC-verified purity and is intended exclusively for laboratory research use under qualified scientific supervision.
AscendLabz GHRP-2 is sourced from cGMP-aligned synthesis facilities and validated for identity, purity, and counter-ion content prior to release. Each lot is independently tested by HPLC, and a Certificate of Analysis (COA) detailing peak area, retention time, and batch number is provided with every order. This level of documentation is intended to support reproducible research and clear chain-of-custody record-keeping in academic and independent laboratory environments.
For research workflows, GHRP-2 is most commonly characterized in cell-culture and isolated-tissue models where investigators examine GHS-R1a (ghrelin receptor) agonism alongside complementary compounds in the growth hormone secretagogue peptides class. Reference standards and dose-response controls should be established by each laboratory prior to experimental use, and all material should be handled by trained personnel using appropriate personal protective equipment.
Storage: Lyophilized GHRP-2 is stable at -20°C protected from light. Reconstituted peptide should be refrigerated at 2-8°C and used within 14 days. Lyophilized peptides should be kept in original sealed packaging until use to prevent moisture uptake.
Reconstitution: Bring the lyophilized vial to room temperature before opening. Reconstitute with bacteriostatic water by injecting solvent down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Gently swirl — do not vortex or shake — until fully dissolved. Allow 5-10 minutes for complete solvation.
Handling: Use sterile technique throughout. Wipe vial septa with isopropyl alcohol before each draw. Document reconstitution date, solvent volume, and resulting concentration on the vial label for traceability.
Every batch of GHRP-2 is analyzed by reverse-phase HPLC and confirmed to be ≥99% pure. Mass spectrometry confirms molecular identity, and counter-ion / residual-solvent panels are performed where applicable. The full Certificate of Analysis ships with each order and is also archived by lot number.
No. GHRP-2 is supplied strictly for in-vitro laboratory research and is not approved by the FDA, EMA, or any regulatory authority for human or veterinary therapeutic use. It must not be administered to humans or animals. By purchasing, you confirm you are a qualified researcher and the material will be used only in a controlled laboratory setting.
All orders ship from the USA via tracked courier within 24-48 hours of payment confirmation. Domestic delivery typically arrives within 2-5 business days in discreet, temperature-stable packaging. Tracking is provided by email at the time of dispatch.
AscendLabz prices GHRP-2 competitively while maintaining ≥99% HPLC-verified purity and a full COA. Bulk-vial bundles offer additional savings for laboratories ordering multi-month research supply. Pricing is reviewed monthly to remain among the most affordable verified-purity sources in the United States.
