Most catalog peptides are in stock and ship right away. For items temporarily out of stock, or a sequence we do not list, we synthesize and deliver within 1–2 weeks. Contact us to confirm availability for a specific product.
Our catalog covers cosmetic peptides, drug peptide reference standards, cyclopeptides, drug peptide impurity standards, substrate peptides, and peptide nucleic acids. Each category has its own page with product details.
Every catalog peptide is purified by HPLC and confirmed by mass spectrometry, and ships with a COA, HPLC chromatogram, and MS report. Additional specifications are available on request.
Yes. We manufacture in-house and supply catalog peptides from milligram samples up to kilogram production volumes. Bulk pricing depends on the peptide and the quantity.
Yes. Beyond the catalog, we synthesize custom peptides, modified sequences, and reference standards to your specification. Send the sequence and requirements, and we will scope it.
Pick the category that matches your work, then choose by sequence, purity, and any modification. If you are not sure, send your application and we will recommend a product or synthesize one to fit.
Catalog peptides are grouped by application, so you can find the right product quickly. Each category below has its own page with product details and selection guidance. Everything we list is made in-house and ships with full QC documentation.
Short-chain peptides used as active ingredients in skincare, including signal, carrier, and neurotransmitter-inhibiting peptides such as Matrixyl, Copper Peptide GHK-Cu, and Argireline. See cosmetic peptides.
Therapeutic peptide compounds supplied as reference standards and research materials for pharmaceutical R&D, including hormone analogs and fragments. For research use only. See drug peptides.
Peptides with a cyclic backbone formed by head-to-tail or side-chain linkage. The ring gives better metabolic stability, stronger receptor binding, and more resistance to enzymes than linear peptides. See cyclopeptides.
Characterized impurity reference standards for the QC and analytical method development of marketed peptide drugs, with full analytical documentation. For research use only. See drug peptide impurities.
Synthetic substrates for proteases, kinases, and other enzymes, including fluorogenic and chromogenic versions for real-time activity assays and inhibitor screening. See substrate peptides.
Synthetic DNA analogs with a peptide-like backbone that bind DNA and RNA with high affinity and resist nucleases and proteases, used in gene-regulation research and diagnostic probes. See peptide nucleic acids.
If a peptide is not in the catalog, we make it. Through custom peptide synthesis and peptide modification, we produce custom sequences, analogs, modified peptides, and reference standards to your specification.
Drug peptides and impurity standards are supplied for laboratory research and analytical use only. They are not approved drugs and are not intended for human or veterinary use.
