How to prepare a bulk raw-material inquiry
For bulk peptide raw materials, include the material name, target quantity, requested specification, destination country and any documentation requirements in the first inquiry. LotusBio can then confirm current availability, packaging format, lead time and which batch documents can be supplied with the quotation.
Before approving a shipment, verify product identity, lot or batch reference, declared specification and the documentation tied to the quoted material. If your procurement process includes independent laboratory testing, confirm the sampling and report requirements before dispatch so the batch can be matched consistently through receiving and review.
For additional procurement checks, review the wholesale supplier checklist and COA verification guide.
Bulk peptide API sourcing FAQ
Can I request a COA before placing a bulk order?
Yes. Tell us the material and target quantity. Available batch documentation can be reviewed during quotation. Final specifications must be matched to the quoted batch.
What information should I include for an API or raw-material quote?
Include product name, target quantity, required specification, destination country and any testing or documentation requirements. This helps us confirm MOQ, packaging, lead time and available batch documents.
Do you supply kilogram-scale peptide raw materials?
Bulk formats depend on the material and current production batch. For kilogram-scale or recurring B2B requirements, contact us with the exact material and forecast quantity for confirmation.
Looking for finished vials instead?
The raw-material list above is for bulk-material sourcing discussions. For catalog vial formats, use Retatrutide specifications, Tirzepatide specifications, Semaglutide specifications, BPC-157 specifications, TB-500 specifications, GHK-Cu specifications, KPV specifications, MOTS-c specifications, NAD+ specifications, SS-31 specifications, Cagrilintide specifications, AOD9604 specifications. Vial packaging and raw-material quantities are quoted separately.
