Documentation
Every lot, documented
A lot-specific Certificate of Analysis is published before the lot ships. Each certificate is issued by an independent third-party laboratory and reports RP-HPLC (UV 214/220 nm) and LC-MS identity, net peptide content and the test date. The lot code on every vial matches a certificate in the public library.

Certificate of Analysis — current lot
A lot-specific Certificate of Analysis is published before the lot ships. Lot record and lab report from an independent third-party laboratory will appear here.

Which wholesale?
Research peptides, not cosmetic peptides
"Wholesale peptides" can mean skincare ingredients sold by the gallon or laboratory compounds sold by the vial. WholesalePeptide.us is the second: lyophilized research peptides with a lot COA from an independent lab, sold for laboratory use only.
Research peptide wholesale (this site)
Vials and 10-vial kits, lot COA with HPLC purity and mass-spec identity, published tiers from one kit, labeled for research use only.
Cosmetic peptide wholesale (not us)
Bulk skincare serums and ingredients for formulators and beauty brands. Different documents, units and rules.

Wholesale peptides for private label
Resellers can put the same tested material under their own label from 10 kits per SKU. Your label carries the lot code, so every vial still traces to its certificate from an independent third-party laboratory.
FAQ
Frequently asked questions
How can I buy peptides wholesale?
Order any mix of compounds from the catalog. WholesalePeptide.us sells 10-vial kits with a minimum of one kit; the discount steps up at 3, 10 and 50 kits, and orders of 100+ kits are quoted. Orders paid by 2:00 PM ET Monday–Friday ship the same day. Open a wholesale account for Net-30 and tax-exempt purchasing.
How do I become a peptide reseller?
Apply for a wholesale account with your business details and resale certificate. Approval takes one business day. Resellers buy at the published tiers, can private label from 10 kits, and must sell for research use only. The full checklist is in our reseller guide.
How do I know if a peptide supplier is legit?
Ask for a lot-specific Certificate of Analysis that names the independent lab, shows the full HPLC chromatogram and an LC-MS mass that matches theory, and states net peptide content. A legitimate supplier publishes its MOQ, price breaks, location and written terms. WholesalePeptide.us publishes all of these; see how to vet a supplier.
What purity are your wholesale peptides?
Every lot is tested by an independent third-party laboratory using RP-HPLC (UV 214/220 nm) and LC-MS identity, and the purity floor is 99%. A lot-specific Certificate of Analysis is published before the lot ships. You can read every certificate in the COA library before you order.
What is the minimum order for wholesale peptides?
The minimum order is one kit (10 vials of one compound and strength). Kits of different compounds count together toward the 3, 10 and 50 kits price breaks. There is no separate wholesale minimum.
Can anyone buy research-only peptides?
WholesalePeptide.us sells to laboratories, universities, research organizations, distributors and research resellers in the United States. Buyers confirm that products are for laboratory research only. We refuse orders that indicate human or animal use. Read our research-use policy.
Where do peptide sellers get their products?
Most research-peptide sellers buy finished, lyophilized vials from a wholesale supplier or contract synthesis lab, then resell them under their own label. The checks that matter are lot traceability and an independent COA for the exact lot you receive, not the seller's brand.
Do I need a license to sell peptides?
Selling research-use-only chemicals generally requires a business registration and, in most states, a sales-tax permit and resale certificate; selling peptides as drugs or supplements is regulated by FDA. Requirements vary by state and product, so confirm with counsel. See do you need a license to sell research peptides.
Does the US manufacture peptides?
Yes. The United States has peptide synthesis and fill facilities, and many suppliers also import active material. WholesalePeptide.us stocks, tests, packs and ships every kit from Sheridan, WY, and each lot's COA names the independent lab that tested it.
How fast do wholesale orders ship?
Orders paid by 2:00 PM ET Monday–Friday dispatch the same day by UPS / USPS, tracked from Sheridan, WY; typical transit is 1–4 business days within the U.S. Orders over $500 ship free. We ship to U.S. addresses only.
