SS-31 Cosmetic Peptides Elamipretide powder CAS 736992-21-5 Peptide Powder Cosmetic Raw Material

SS-31 belongs to the Szeto-Schiller (SS) series of mitochondria-targeted cationic tetrapeptides. Its generic name is Elamipretide, also known as Bendavia and MTP-131. It is currently the most well-studied mitochondria-targeted antioxidant peptide in clinical research. It received accelerated approval from the FDA in 2025 for the rare disease Barth syndrome. Other indications are still in the clinical or research stage. Research-grade SS-31 is mostly used in cell and animal experiments, and its administration in humans must be conducted under the guidance of physicians.

These products are APIs (Active Pharmaceutical Ingredient) and not a finished drug. 

It is intended strictly for research and laboratory use only.

Buyers are required to fully comply with all applicable laws and regulations regarding the handling and use of this material.

D-Arg: D-Arginine (provides positive charge and targets the inner mitochondrial membrane)
Dmt: 2,6-Dimethyltyrosine (core antioxidant group that scavenges free radicals)
Lys: Lysine (enhances membrane penetration and binds to cardiolipin via electrostatic interaction)
Phe: Phenylalanine (hydrophobic structure for biological membrane penetration)
C-terminal amidation modification: Resists degradation by proteases in vivo and improves stability

Product quality is the foundation of our business. Our peptide compounds are synthesized using the solid-phase peptide synthesis method (SPPS), purified by high-performance liquid chromatography (HPLC), and verified by mass spectrometry (MS).
Each batch of products comes with an analysis certificate (COA), which contains key data: ••• Purity (HPLC) • Molecular weight (MS) • • • Moisture content • • • Residual solvents • • Microbial limits (if applicable).
For customers with stricter regulatory requirements, we can also provide third-party testing reports, endotoxin (LAL) data, and stability study documents. 2. Customized Services and R&D Support
We provide flexible customized synthesis services and support from an experienced R&D team. Whether you need a new peptide sequence, cosmetic-grade purity, or modified molecules (such as PEGylation or acetylation), we can deliver high-quality products on time. Our services include:
•• Custom peptide synthesis (milligram to kilogram level)
••• Peptide modification and labeling
•• Small molecule synthesis
• Project-based R&D and large-scale production
We work closely with our clients to ensure technical feasibility, rapid delivery, and cost control throughout the entire development cycle. 3. Diverse product portfolio
We offer a wide range of products that are continuously expanding:
••• Peptides: GLP-1 analogues (such as sitagliptin, tazapetide, retactide, etc.), cosmetic-grade peptides (such as acetyl hexapeptide-8, Matrixyl, etc.), anti-aging peptides, and research-grade peptides.
•• Small molecule compounds: Cognitive enhancers, NAD+ precursors/promoters (such as NMN, NR, NADH) and intermediates.
• Biochemical products: Amino acid derivatives, enzyme cofactors, and custom reagents.
To meet the constantly changing market demands, we regularly introduce new products. At the same time, we also provide batch pre-order services for customers with continuous or seasonal demands.
