Description
GHRP-2
GHRP-2 (Growth Hormone Releasing Peptide-2), also known as Pralmorelin, is a high-purity synthetic hexapeptide and a potent agonist of the ghrelin receptor. In the landscape of advanced endocrine research, GHRP-2 is recognized for its superior efficiency in stimulating the pulsatile release of endogenous growth hormone (GH) from the anterior pituitary compared to its predecessor, GHRP-6. By antagonizing somatostatin and directly acting on pituitary somatotrophs, GHRP-2 provides researchers with a robust experimental model to investigate the Growth Hormone/IGF-1 axis, systemic nitrogen retention, and the molecular pathways of protein synthesis. While it retains the ability to modulate appetite centers, its orexigenic effect is significantly more controlled than first-generation secretagogues, making it a preferred tool for research focusing on lean mass homeostasis and metabolic efficiency.
Our GHRP-2 is synthesized in an ISO 9001:2015 certified environment utilizing high-precision Solid-Phase Peptide Synthesis (SPPS). We achieve an ultra-high chemical purity of ≥99%, verified by HPLC and Mass Spectrometry (MS). This rigorous production standard ensures the peptide is free from truncated sequences and residual chemical reagents, guaranteeing the consistency and structural fidelity required for high-stakes metabolic signaling studies.

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the GHRP-2 powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and maintains the molecular stability of the hexapeptide during storage.
High-Fidelity Sequence Integrity
Every batch undergoes strict Mass Spectrometry (MS) to confirm the exact amino acid sequence, ensuring maximal receptor binding affinity and reproducible results in complex hormonal signaling assays.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the GHRP-2 cake is at the base.
-
Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 10-14 days for optimal results.
