Supply at a Glance
What Are Therapeutic Peptides?
Short amino-acid chains — typically 2 to 50 residues — engineered to act on defined biological targets, offering higher specificity and lower off-target toxicity than conventional small molecules.
Why Source from SONYT
Fmoc-based solid-phase synthesis with purification to research and pharmaceutical grade. Every shipment carries a batch-specific COA, HPLC chromatogram and MS report.
Built for Global Supply
Milligram research quantities through kilogram-scale production, cold-chain packaging and stable lead times for distributors and institutions across North America and Europe.

Therapeutic & Pharmaceutical Peptides — FAQ
Frequently asked questions about this peptide category.
What are therapeutic and pharmaceutical peptides?
Short chains of amino acids used as active ingredients in drug development and as research tools. Compared with small-molecule drugs, peptides offer high target specificity and low toxicity, which is why this category is central to metabolic disease, oncology, and immunology research.
Which peptide classes does this category cover?
This category covers the major therapeutic peptide classes: GLP-1 receptor agonists and other metabolic peptides, RGD / integrin-binding tumor-targeting peptides, antimicrobial peptides (AMPs), cell-penetrating peptides, and peptides for immunology and vaccine research.
How are the peptides in this category quality-controlled?
Every peptide is synthesized on our Fmoc SPPS platform, and every batch must pass HPLC purity analysis and MS identity confirmation before release. Products also undergo two rounds of re-inspection before leaving the warehouse.
Can you synthesize analogs and modified sequences of these peptides?
Yes. Beyond catalog items, we synthesize custom analogs and modified sequences — including N-acetylation, C-terminal amidation, phosphorylation, and conjugation. Send us your sequence and specification and our technical team will confirm feasibility.
Can these peptides be supplied in larger volumes?
Yes. Products in this category are available from research quantities for laboratories up to larger volumes for distributors, with batch-to-batch consistency supported by our Shanghai production base.
How do I request a quotation for a peptide in this category?
Contact us with the product name, CAS number, required quantity, and destination country. Our sales team typically responds with pricing and lead time within 24 hours.
