Wholesale Research Peptide Supplier Checklist
Buyer guide · Supplier due diligence
Use this checklist to organize a supplier conversation before requesting a wholesale quotation. It is intended for research-use procurement and does not make medical or therapeutic claims.
1. Product and specification
- Product name, code and physical form
- Available pack sizes and packaging format
- Batch documentation and stated analytical methods
- Storage and handling information supplied with the product
2. Commercial terms
- Minimum order quantity and sample policy
- Quotation validity and payment terms
- Production or preparation lead time
- Replacement process for documented shipping damage or discrepancy
3. Documentation
- COA or batch report linked to the supplied batch
- Product and package labels that match the order
- Commercial invoice and packing list
- Shipping and customs documents where applicable
4. OEM and private-label questions
- Label and packaging formats available
- Artwork review and approval process
- MOQ for custom packaging
- Lead time for a repeat order
5. Communication and verification
Use a business email, keep the quotation and documentation together, and ask for clarification when product names, batch numbers or test details do not match. A clear supplier should be able to explain what is included in a quotation and which documents are available.
Scope note: Research-use supply information should not be presented as medical treatment, a prescription, or a claim of regulatory approval.
