Wholesale & bulk research peptide supply
Built for distributors, laboratories and research suppliers who buy in repeat volumes — not single vials. This page explains how our wholesale model works, what determines price, and what documentation travels with each shipment.
What "wholesale" means here
We supply three commercial formats. They differ in volume, packaging and documentation depth — not in the underlying product standard.
Vial & kit supply
Standard vial formats from 10-unit MOQs, suitable for laboratories and small distributors. Batch COA included.
Bulk quantities
Higher-volume vial packs and gram-scale material for distributors and formulators. Quoted per order.
OEM / private label
Your label, box and documentation package. See the OEM page.
What determines the price
| Factor | Effect on price | Notes |
|---|---|---|
| Peptide and strength | Base cost | Longer sequences and higher loads cost more per vial |
| Quantity tier | Lower unit cost at volume | Tiers apply per SKU, not across mixed orders |
| Packaging | Vial size, box, inserts | Custom packaging is quoted separately |
| Documentation | Standard COA included; extra testing quoted | Third-party testing adds lead time |
| Destination | Freight and compliance cost | Some destinations are restricted — see Shipping & Customs |
Order flow
- RFQ: send SKUs, strengths, quantities and destination.
- Quotation: we confirm availability, tier price, lead time and documentation.
- Sample (optional): qualified buyers can request a sample with its batch COA.
- Payment & production: T/T, or terms for repeat buyers after review.
- Shipping: tracked export shipment with commercial invoice and packing list.
This is the short version. The full qualification sequence — sampling, payment structure, document review and arrival checks — is set out in how to buy research peptides from China, and the evaluation framework for a new supplier in the 12-point supplier checklist.
Documentation that ships with every order
- Batch-specific certificate of analysis (identity, purity, appearance, water content where applicable)
- HPLC chromatogram for the lot
- Mass-spectrometry confirmation
- MSDS and storage instructions
- Commercial invoice and packing list for customs
