Core Molecular Specs & Technical Index
Basic Properties
GHRP 2 peptide is a white to off-white lyophilized powder with a molecular weight of approximately 817.9 Da. It is highly soluble in water and common buffers, with a solubility of up to 10 mg/mL in deionized water. The peptide is stable under recommended storage conditions of -20°C, away from light and moisture.
Purity and Quality Parameters
High-purity GHRP 2 peptide is defined by a minimum of 98% purity as determined by HPLC analysis. Additional quality indices include:
- Peptide Content: ≥ 80% (by weight)
- Water Content: ≤ 5% (Karl Fischer method)
- Acetate Content: ≤ 10% (as counterion)
- Endotoxin Level: ≤ 1 EU/mg
- Microbial Limits: Total aerobic count ≤ 100 CFU/g, yeast and mold ≤ 10 CFU/g
Solubility and Storage
For optimal stability, GHRP 2 peptide should be stored as a lyophilized powder at -20°C. Once reconstituted in sterile water or buffer, it is recommended to use immediately or store at 2-8°C for up to 48 hours. Avoid repeated freeze-thaw cycles to maintain integrity.
Industry data indicates that over 85% of peptide-related quality complaints in cosmetic raw material procurement stem from purity below 95% or improper storage conditions. Sourcing GHRP 2 peptide with verified 98% purity and clear storage guidelines reduces formulation failure rates by up to 40%.
Manufacturing & Quality Control
Production Process
GHRP 2 peptide is manufactured using solid-phase peptide synthesis (SPPS), a method that ensures precise amino acid sequence assembly. The process involves stepwise coupling of protected amino acids on a resin support, followed by cleavage and deprotection. This approach yields high purity and consistent batch quality.
Purification and Analysis
After synthesis, the crude peptide undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve the target purity of 98% or higher. Each batch is then analyzed using mass spectrometry (MS) for molecular weight confirmation and HPLC for purity verification. Additional tests include amino acid analysis and peptide content determination.
Third-Party Testing and Certification
Reputable suppliers provide third-party lab certificates of analysis (CoA) for each batch of GHRP 2 peptide. These certificates include detailed results for purity, peptide content, water content, endotoxin levels, and microbial limits. Buyers should request CoA from accredited laboratories to ensure compliance with industry standards.
- HPLC Purity Report: Confirms ≥ 98% purity
- Mass Spectrometry: Verifies molecular weight
- Endotoxin Testing: Ensures safety for research use
- Microbiological Analysis: Validates sterility
- Stability Data: Demonstrates shelf life under recommended conditions
Commercial Application Scenarios
Cosmetic Formulation
In the cosmetic industry, GHRP 2 peptide is incorporated into advanced skincare products aimed at promoting skin firmness and elasticity. Its high purity ensures compatibility with other active ingredients and minimizes the risk of irritation. Formulators use it at concentrations ranging from 0.1% to 1% in serums, creams, and masks.
Lab Research
Research laboratories utilize GHRP 2 peptide for studies related to cellular signaling and peptide-receptor interactions. The 98% purity standard is critical for reproducible experimental results. Researchers often require small quantities (1 mg to 100 mg) for in vitro assays and preliminary investigations.
Bulk Wholesale Usage
Bulk buyers, including peptide distributors and contract manufacturers, source GHRP 2 peptide in quantities ranging from 1 gram to 1 kilogram. These buyers prioritize consistent quality, competitive pricing, and reliable supply chains. High-purity material reduces the need for additional purification steps in downstream processing.

Bulk Purchase Selection Guide
Common Pitfalls
Buyers often encounter issues such as inconsistent purity, lack of documentation, and improper storage during transit. To avoid these, always verify the supplier's manufacturing capabilities and request batch-specific CoA. Another common pitfall is assuming all GHRP 2 peptide products are identical; variations in synthesis and purification methods can significantly impact quality.
Selection Standards
When sourcing GHRP 2 peptide, prioritize suppliers who provide transparent manufacturing details, including synthesis method, purification process, and quality control protocols. Look for suppliers with ISO 9001 certification or similar quality management systems. Additionally, confirm that the peptide is packaged in airtight, light-resistant containers to maintain stability during shipping.
Buyer Checklist
- Request a sample for in-house testing before bulk purchase
- Verify HPLC purity report and mass spectrometry data
- Check endotoxin and microbial limit results
- Confirm storage and handling instructions
- Evaluate supplier communication and lead times
