Wholesale research peptides for laboratories and universities
WholesalePeptide.us supplies research peptides to university, government and biotech laboratories by card, purchase order or Net-30 terms. Every kit is 10 vials of one compound and strength, every lot has a Certificate of Analysis from an independent third-party laboratory (RP-HPLC purity and LC-MS identity) published before it ships, and orders paid by 2:00 PM ET Monday–Friday dispatch the same day from Sheridan, WY. Tax-exempt institutions purchase without sales tax once a certificate is on file.
Requirements
- Institution name, department and shipping address (U.S. only)
- Purchase order or card; Net-30 after account review
- Tax-exemption certificate if applicable
- Principal investigator or lab manager contact for documentation
What procurement teams get
- Published pricing — the same tiers for every buyer, at 3, 10 and 50 kits, so a quote is never needed below 100 kits. See the price list.
- Lot documentation up front — download the COA for the lot you will receive from the COA library before you raise the PO.
- Vendor onboarding pack — W-9, certificate of insurance and our research-use policy, sent on request to wholesale@wholesalepeptide.us.
- Consistent identity — every product page lists the PubChem record, CAS number and molecular formula for the compound.
Paying by purchase order or net terms
Send your PO to wholesale@wholesalepeptide.us or attach it at checkout. Net-30 is available to qualified laboratories and distributors after account review. Approval takes one business day. Invoices reference the PO number and list the lot code of every kit shipped, which keeps receiving and audit records aligned with the certificates.
Documentation for your lab notebook
Each certificate reports RP-HPLC purity with the chromatogram, LC-MS observed mass against theoretical mass, net peptide content and test date, and names the laboratory that tested the lot (Freedom Diagnostics, Mistral Diagnostics, Vanguard Laboratory, Amino Metrics and Accumarks). Our guide to reading a peptide COA explains each field, and how to vet a wholesale peptide supplier gives a checklist procurement teams can reuse for any vendor.
Larger programs
For multi-month studies or more than 100 kits, request a bulk peptides quote; we can reserve stock from a single lot so the whole program runs on one certificate.
