Target Keyword: ss 31 peptide
Core Molecular Specs & Technical Index
The SS-31 peptide, also known as Elamipretide, is a mitochondrial-targeted antioxidant composed of a unique sequence of four amino acids: D-arginine, dimethyltyrosine, L-lysine, and L-phenylalanine. This small, cell-permeable peptide is specifically designed to selectively bind to cardiolipin, a phospholipid found in the inner mitochondrial membrane. By stabilizing this interaction, the SS-31 peptide restores mitochondrial bioenergetics and reduces the production of reactive oxygen species (ROS). For B2B buyers, including cosmetic formulators, lab researchers, and bulk wholesalers, the core value lies in its high specificity for mitochondrial dysfunction, offering a targeted approach for anti-aging and metabolic health applications.
- Purity Standard: Industry-grade SS-31 peptide is typically available at ≥98% purity, verified by High-Performance Liquid Chromatography (HPLC). Premium suppliers offer ≥99% for research-grade applications.
- Molecular Weight: The peptide has a molecular weight of approximately 639.8 g/mol, ensuring efficient cellular uptake and bioavailability in formulations.
- Solubility: SS-31 peptide is highly soluble in water and phosphate-buffered saline (PBS), making it suitable for injectable solutions, topical serums, and lyophilized powder formats.
- Storage Requirements: Lyophilized powder should be stored at -20°C, protected from light and moisture. Reconstituted solutions are stable for up to 30 days at 4°C.
- Formulation Compatibility: The peptide is compatible with common cosmetic bases (e.g., hyaluronic acid, glycerin) and lab buffers, but should avoid high-pH environments (above pH 7.5) to maintain stability.
Industry data from 2025 indicates that the global SS-31 peptide market is projected to grow at a CAGR of 12.3%, driven by increasing R&D investments in mitochondrial-targeted therapies. Over 60% of current clinical studies focus on age-related disorders, with preliminary results showing a 35% improvement in mitochondrial function markers in treated groups.
Manufacturing & Quality Control
The production of SS-31 peptide involves solid-phase peptide synthesis (SPPS), a method that allows for precise control over amino acid sequence and purity. After synthesis, the peptide undergoes cleavage and deprotection, followed by purification via preparative HPLC. Quality control (QC) is critical for B2B buyers, as impurities can affect both research outcomes and product safety. Reputable suppliers implement multi-step QC protocols, including mass spectrometry (MS) for molecular weight confirmation and amino acid analysis for sequence verification.
- Third-Party Testing: Independent laboratories provide certificates of analysis (CoA) for each batch, detailing purity, endotoxin levels, and heavy metal content.
- Certification Standards: Look for suppliers with ISO 9001:2015 certification for quality management and GMP (Good Manufacturing Practice) compliance for pharmaceutical-grade production.
- Batch Consistency: High-quality manufacturers ensure batch-to-batch consistency with a deviation of less than 2% in purity and potency, essential for reproducible research.
- Stability Testing: Accelerated stability studies (e.g., 40°C/75% RH for 6 months) confirm the peptide's shelf life, typically 24-36 months for lyophilized powder.
- Regulatory Compliance: For cosmetic and lab use, suppliers should adhere to REACH (EU) and FDA guidelines for raw materials, providing full documentation for customs clearance.
Commercial Application Scenarios
The SS-31 peptide is increasingly adopted across multiple B2B sectors due to its targeted mitochondrial action. In cosmetic formulation, it is incorporated into anti-aging serums and creams to reduce oxidative stress in skin cells, improving elasticity and reducing fine lines. Lab researchers utilize the peptide for in vitro and in vivo studies on metabolic disorders, such as obesity and diabetes, where mitochondrial dysfunction is a key factor. Bulk wholesale buyers, including contract manufacturers and distributors, source SS-31 peptide for large-scale production of nutraceuticals and cosmeceuticals, leveraging its high stability and cost-efficiency.
- Cosmetic Formulation: Used at concentrations of 0.1-1% in topical products, SS-31 peptide enhances mitochondrial function in dermal fibroblasts, promoting collagen synthesis and reducing UV-induced damage.
- Lab Research: In preclinical studies, the peptide is administered at doses of 1-10 mg/kg in animal models to evaluate its effects on cardiac and renal mitochondrial function.
- Bulk Wholesale: Large-scale orders (e.g., 100g to 1kg) are common for nutraceutical production, with suppliers offering custom packaging and labeling for OEM clients.
- Clinical Trials: Phase II trials for age-related macular degeneration (AMD) and heart failure have shown promising results, driving demand for GMP-grade SS-31 peptide.

Bulk Purchase Selection Guide
When sourcing SS-31 peptide in bulk, B2B buyers must navigate common pitfalls to ensure quality and cost-efficiency. One frequent issue is receiving low-purity peptides that fail to meet research or formulation standards, leading to wasted resources. Another challenge is inconsistent batch quality, which can compromise reproducibility in studies. To avoid these problems, buyers should prioritize suppliers with transparent documentation and third-party testing. Additionally, regulatory compliance is crucial for international shipments, as customs may require certificates of origin and safety data sheets.
- Quality Verification: Request a CoA for each batch, including HPLC chromatogram and MS spectrum. Verify purity levels and endotoxin limits (e.g., <0.1 EU/mg for injectable use).
- Regulatory Compliance: Ensure the supplier provides full documentation for REACH, FDA, or other relevant regulations. Check for GMP certification if the peptide is intended for clinical use.
- Cost-Efficiency: Compare pricing per gram for bulk orders (e.g., 10g, 100g, 1kg). Look for volume discounts and consider total cost including shipping and customs fees.
- Supplier Reputation: Research supplier reviews and request references from other B2B clients. A reliable supplier will offer technical support and sample testing.
- Packaging and Storage: Confirm that the peptide is packaged in vacuum-sealed, light-protected vials. Ask about shelf life and storage conditions to avoid degradation.
