Core Molecular Specs & Technical Index
AOD 9604 peptide is a synthetic fragment of human growth hormone (hGH), specifically amino acids 177-191. This modified peptide is engineered to target lipid metabolism without affecting blood glucose levels, making it a high-value raw material for cosmetic formulations and laboratory research. For B2B buyers—including cosmetic chemists, research labs, and bulk peptide distributors—the core value lies in its high purity, precise molecular weight, and batch-to-batch consistency. These specifications directly impact formulation stability, research reproducibility, and end-product safety.
Basic Properties and Purity Standards
The molecular formula of AOD 9604 peptide is C78H132N22O23S2, with a molecular weight of approximately 1814.1 Da. Professional sourcing requires a minimum purity of 98% by HPLC analysis, with premium grades reaching 99% or higher. The peptide is supplied as a lyophilized white powder, soluble in water or sterile saline at concentrations up to 10 mg/mL. Storage conditions demand long-term stability at -20°C and short-term handling at 2-8°C to prevent degradation.
Five Critical Technical Specifications
- Purity by HPLC: ≥98% (premium grade ≥99%) with single impurity peaks below 0.5%
- Peptide Content: 80-90% net peptide weight, excluding counterions and water
- Endotoxin Levels: <1.0 EU/mg for research use; <0.1 EU/mg for cosmetic-grade applications
- Solubility: ≥10 mg/mL in water or PBS buffer at pH 7.4, forming a clear solution
- Reconstitution Stability: Stable for 7 days at 4°C after reconstitution in sterile water
Industry data from 2024 peptide manufacturing reports indicates that 92% of quality complaints in cosmetic peptide sourcing relate to purity below 97% or incorrect molecular weight verification. Third-party HPLC and mass spectrometry certification is now a baseline requirement for professional buyers.
Manufacturing & Quality Control
The production of AOD 9604 peptide follows a rigorous solid-phase peptide synthesis (SPPS) process, typically using Fmoc chemistry. This method allows for precise amino acid sequence assembly with minimal side reactions. After synthesis, the crude peptide undergoes preparative HPLC purification to remove truncated sequences and deletion impurities. The final product is lyophilized under controlled conditions to preserve structural integrity.
Production Process and Purification
Manufacturing begins with resin loading and sequential amino acid coupling, followed by cleavage and deprotection. The crude peptide is then purified using reverse-phase HPLC with a C18 column and a gradient of acetonitrile in water. Fractions with purity above 98% are pooled and lyophilized. Each batch is subjected to mass spectrometry (ESI-MS or MALDI-TOF) to confirm molecular weight and amino acid analysis for sequence verification.
Third-Party Testing and Certification
Reputable suppliers provide a Certificate of Analysis (CoA) for each batch, including HPLC chromatogram, mass spectrometry data, and endotoxin testing results. Additional certifications may include:
- HPLC purity report with peak integration and impurity profiling
- Mass spectrometry confirmation of molecular weight (expected 1814.1 Da)
- Endotoxin testing by LAL method (limit <1.0 EU/mg)
- Residual solvent analysis (acetonitrile, TFA) per USP guidelines
- Stability data under recommended storage conditions
Commercial Application Scenarios
AOD 9604 peptide serves multiple B2B markets, each with distinct requirements for purity, formulation, and documentation. Understanding these scenarios helps buyers select the appropriate grade and supplier.
Cosmetic Formulation
In cosmetic applications, AOD 9604 peptide is incorporated into serums, creams, and masks targeting skin firmness and contouring. Cosmetic-grade material requires endotoxin levels below 0.1 EU/mg and full documentation for regulatory compliance. Formulators typically use concentrations of 0.1-1.0% in water-based systems, with pH buffers to maintain stability. The peptide's ability to support lipid metabolism makes it a popular ingredient in anti-aging and body-contouring products.
Laboratory Research
Research labs use AOD 9604 peptide for in vitro and in vivo studies on metabolic pathways, adipocyte differentiation, and receptor binding. Research-grade material requires purity ≥98% with detailed analytical data for publication. Batch-to-batch consistency is critical for reproducible results, and suppliers often provide bulk discounts for multi-gram orders. Typical research quantities range from 10 mg to 1 gram per project.
Bulk Wholesale Usage
Bulk buyers, including contract manufacturers and peptide distributors, require large quantities (10-100 grams) with competitive pricing and reliable supply chains. These buyers prioritize certified purity, stable lead times, and COA documentation. Bulk AOD 9604 peptide is often supplied in sealed vials or bulk containers with desiccant, and shipping under cold chain conditions is standard for international orders.
AOD 9604 Peptide VS Ordinary Low-Grade Peptides
| Item | Our Product (AOD 9604 Peptide) | Alternatives (Low-Grade Peptides) | Advantages |
|---|---|---|---|
| Purity (HPLC) | ≥98% (premium ≥99%) | Often 90-95% | Higher purity reduces impurities and improves formulation stability |
| Endotoxin Level | <0.1 EU/mg (cosmetic grade) | Often >1.0 EU/mg | Safer for topical and research applications |
| Molecular Weight Verification | ESI-MS or MALDI-TOF per batch | Often not verified | Ensures correct peptide identity and sequence integrity |

Bulk Purchase Selection Guide
Selecting a reliable supplier for AOD 9604 peptide requires careful evaluation of technical specifications, documentation, and supply chain capabilities. Common pitfalls include accepting low-purity material, ignoring endotoxin limits, and failing to verify batch consistency.
Common Pitfalls to Avoid
- Accepting purity below 98%: Lower purity increases risk of side reactions in formulations and reduces research reproducibility
- Ignoring endotoxin testing: For cosmetic use, endotoxin levels above 0.1 EU/mg can cause irritation or contamination
- Lack of COA documentation: Without HPLC and mass spec data, peptide identity and purity cannot be verified
- Inadequate storage conditions: Peptides degrade rapidly at room temperature; cold chain shipping is essential
Selection Standards and Buyer Checklist
Professional buyers should request the following before placing an order:
- Certificate of Analysis (CoA) with HPLC chromatogram and mass spectrometry data
- Endotoxin testing report (LAL method) with specific EU/mg value
- Stability data under recommended storage conditions (at least 6 months at -20°C)
- Batch number and manufacturing date for traceability
- Shipping method with cold chain packaging and temperature monitoring
