Wholesale & bulk peptide supply
Volume pricing, custom synthesis, white-label packaging and dedicated account management for research labs, clinics and resellers.
Built for volume, priced for scale
Trypsyn supplies research-grade peptides in bulk to universities, contract research organizations, clinical research sites and licensed resellers worldwide. Every wholesale order ships with the same lot-specific COA as retail orders — the only difference is the price per milligram.
Volume tiers
10+ vials: 10% off. 50+ vials: 20% off. 100+ vials: custom quote with priority production slot.
Custom synthesis
Need a sequence not in our catalog? We offer custom peptide synthesis from 5mg to gram scale, with typical turnaround of 2–3 weeks.
White-label
Blank vials, custom labels or your brand packaging available on orders of 500+ vials. Your customers never see our name.
How wholesale accounts work
- Apply — Email us with your organization details, estimated monthly volume and the products you need.
- Verify — We review your application and set up a wholesale account with tiered pricing.
- Order — Place orders through your dedicated account manager or via our wholesale portal.
- Track — Real-time production updates, batch numbers and COA delivery before shipment.
Quality is the same at every volume
Wholesale does not mean a different product. Every vial — whether you order one or one thousand — comes from the same production runs, passes the same HPLC and mass-spec verification, and ships with a lot-specific Certificate of Analysis. We do not maintain separate "retail" and "wholesale" quality tiers.
