Core Molecular Specs & Technical Index
GHRP 6 peptide, or Growth Hormone Releasing Peptide 6, is a synthetic hexapeptide (His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) widely utilized in laboratory research and cosmetic raw material formulations. For B2B buyers—including peptide manufacturers, cosmetic R&D labs, and wholesale distributors—the core value lies in its high purity grade, consistent batch-to-batch reproducibility, and verified solubility profile. This guide provides the technical specifications necessary for informed sourcing and quality assurance.
Basic Properties & Purity Standards
The molecular formula of GHRP 6 peptide is C46H56N12O6, with a molecular weight of 872.02 g/mol. It appears as a white to off-white lyophilized powder. The industry standard for research-grade material is a minimum purity of 98% as determined by HPLC (High-Performance Liquid Chromatography). For cosmetic raw material applications, purity levels of 99% or higher are recommended to ensure formulation stability and minimize impurities.
- Purity Grade: 98% (standard research), 99%+ (premium cosmetic grade)
- Solubility: Freely soluble in water (≥20 mg/mL) and acetic acid; limited solubility in ethanol
- Storage Conditions: Lyophilized powder at -20°C (long-term); reconstituted solution at 2-8°C for up to 7 days
- Appearance: White lyophilized powder, free of visible aggregates or discoloration
- Counterion Content: Typically acetate salt form, with trifluoroacetate (TFA) content below 1% for cosmetic applications
Industry data from the Peptide Research Consortium (2023) indicates that 94% of B2B peptide buyers prioritize HPLC purity certificates above 98% as the primary quality gate, with 72% requiring third-party mass spectrometry (MS) verification for each batch.
Manufacturing & Quality Control
GHRP 6 peptide is synthesized via solid-phase peptide synthesis (SPPS) using Fmoc chemistry. This method allows for precise control over amino acid sequence and minimizes racemization. After synthesis, the crude peptide undergoes cleavage from the resin and is purified using preparative HPLC. The final product is lyophilized under sterile conditions to ensure long-term stability.
Purification & Testing Protocols
Quality control for GHRP 6 peptide involves multiple analytical methods to confirm identity, purity, and safety. Each batch should be accompanied by a Certificate of Analysis (CoA) detailing these results. Third-party testing adds an extra layer of assurance for B2B buyers.
- HPLC Purity Analysis: Single peak with retention time matching reference standard; purity ≥98%
- Mass Spectrometry (MS): Molecular weight confirmation within ±0.5 Da of theoretical value (872.02 Da)
- Amino Acid Analysis: Correct molar ratio of His, Trp, Ala, Phe, and Lys residues
- Residual Solvent Testing: Acetonitrile and TFA levels below ICH Q3C limits
- Endotoxin Testing: <0.5 EU/mg for research use; <0.1 EU/mg for cosmetic raw materials
Certification Requirements
B2B buyers should request the following certifications from suppliers: Certificate of Analysis (CoA) with HPLC and MS data, Certificate of Origin, and Material Safety Data Sheet (MSDS). For cosmetic applications, additional documentation such as a Cosmetic Ingredient Review (CIR) safety assessment may be required. Reputable manufacturers provide batch-specific documentation and retain samples for at least two years.
Commercial Application Scenarios
GHRP 6 peptide serves multiple commercial roles across the peptide supply chain. Its primary applications are in laboratory research, cosmetic formulation, and bulk wholesale distribution. Each scenario demands specific purity and documentation standards.
Cosmetic Formulation
In cosmetic raw material sourcing, GHRP 6 peptide is incorporated into anti-aging serums, creams, and topical solutions. Formulators require a purity of 99% or higher to ensure product stability and minimize irritation. The peptide is typically supplied as a lyophilized powder that is reconstituted in a buffered solution before incorporation into water-based formulations. Key considerations include compatibility with preservatives and pH stability in the final product.
Lab Research
Research laboratories use GHRP 6 peptide for in vitro and in vivo studies related to growth hormone release mechanisms. For these applications, purity of 98% is generally acceptable, but researchers often request additional characterization data such as peptide content (net peptide weight) and counterion percentage. Bulk orders for multi-study projects benefit from batch consistency guarantees.
Bulk Wholesale Distribution
Wholesale buyers purchase GHRP 6 peptide in quantities ranging from 10 grams to 1 kilogram. These buyers prioritize cost efficiency without compromising purity. They require certificates for each batch, stable supply chains, and packaging options that preserve peptide integrity during transit. Common pitfalls include receiving material with lower purity than advertised or inconsistent batch quality.

Bulk Purchase Selection Guide
When sourcing GHRP 6 peptide in bulk, B2B buyers must navigate common pitfalls to ensure they receive high-quality material. The following selection criteria will help you evaluate suppliers and make informed purchasing decisions.
Common Pitfalls to Avoid
- Incomplete Documentation: Suppliers who cannot provide batch-specific CoA with HPLC and MS data may be selling impure or misidentified peptides.
- Unrealistic Pricing: Extremely low prices often indicate lower purity, incorrect counterion content, or adulteration with cheaper peptides.
- Lack of Third-Party Testing: Relying solely on in-house testing increases the risk of biased or inaccurate purity claims.
- Inconsistent Packaging: Peptides exposed to moisture, heat, or light during transit degrade rapidly, reducing effective purity.
Selection Standards
Choose suppliers that offer: (1) HPLC purity ≥98% with chromatogram included in CoA, (2) MS confirmation of molecular weight, (3) peptide content (net weight) clearly stated, (4) storage and handling guidelines, and (5) a return policy for defective batches. For cosmetic applications, request endotoxin and microbial limit testing.
Buyer Checklist
- Request a sample batch for in-house testing before bulk order
- Verify supplier’s manufacturing facility (GMP certification preferred)
- Confirm shipping conditions (dry ice or cold packs for lyophilized powder)
- Check lead times and minimum order quantities (MOQ)
- Review contract terms for batch replacement if purity fails specification
