Scalable Bulk & Custom Synthesis

From milligrams for laboratory chemical testing to multi-kilogram production runs for commercial cosmetic raw materials. We support custom SPPS synthesis, lipidations, cyclization, and diverse counter-ion salts.

Cold-Chain Global Fulfillment

Lyophilized peptides are packaged under nitrogen blanket in sealed borosilicate vials. We offer insured express shipping to North America, Europe, Asia, and Latin America with dedicated customs documentation.

Peptide Catalog Frequently Asked Questions

Essential information on product purity, ordering procedures, and regulatory compliance.

What analytical purity standards are verified for catalog peptides?

Every batch produced by COSPEP Biotech is analyzed using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (LC-MS / ESI-MS) to confirm sequence identity and guarantee purity levels between ≥98.0% and ≥99.0%. Each order includes a batch-specific Certificate of Analysis (COA).

Do you provide bulk peptide raw material supply and custom synthesis?

Yes, we provide bulk chemical supply ranging from milligram analytical standards up to multi-kilogram commercial production batches. We also offer custom solid-phase peptide synthesis (SPPS), sequence modifications, counter-ion exchanges, and customized aliquoting.

How are peptide chemical raw materials packaged and stored?

All peptides are supplied as lyophilized solid cakes or crystalline powders sealed in inert borosilicate glass vials under nitrogen blanket. Recommended storage is desiccated at -20°C for analytical peptides, or 2-8°C protected from light for cosmetic raw materials.

Are catalog peptides approved for human consumption or therapeutic use?

No. All catalog items are chemical raw materials and reference standards intended solely for in vitro laboratory chemical research, analytical calibration, and cosmetic raw material formulation. Products are not intended for human or animal consumption, diagnostic, or therapeutic use.

Looking for a Specialized Sequence?

Our custom peptide synthesis laboratory can produce specialized sequences, cyclic peptides, and modified conjugates with HPLC purity up to 99%.
