Define your order

Choose your product, specification, quantity and destination. Include repeat-order or packaging requirements.

Review batch documents

Browse public COA reports and ask which document applies to the product, format and batch proposed in your quotation.

Confirm the details

Confirm minimum order quantity, availability, packing and lead time in the actual quotation before approving an order.

What should you check before a wholesale order?

Choose finished vials or bulk raw material

For finished vials, state the product, amount per vial, number of vials per box and total box count. For bulk peptide raw materials, state the required total mass in mg, g or kg and preferred container size. These are separate quotation formats; a vial quantity does not specify a raw-material order.

Match the COA to the proposed supply

Check the product identity, report number, sample or batch identifier and tests performed. A reference report does not establish the result for a different batch, and a raw-material COA does not describe a finished-vial sample. Review our third-party testing information and COA verification guide, then ask which available document matches your quotation.

Can I purchase sample vials for laboratory testing?

Sample-vial purchases can be discussed before a larger order. Tell us the product, specification, desired number of vials, intended laboratory tests and receiving country. Our team confirms sample availability, quantity, pricing and shipping arrangements before purchase. Sample quantities are quoted separately from standard 10-vial catalog boxes.

Use the “Sample vials for laboratory testing” inquiry type below. Ask for the sample batch identifier and retain it with your results; confirm the batch again for a later bulk order.

Confirm MOQ, lead time and delivery details

Minimum order quantity and lead time depend on the product, format and requested quantity. They are confirmed in the actual quotation. Include your destination and required receipt date so availability, dispatch timing, shipping arrangements and receiving documents can be reviewed together. Do not treat a catalog listing as a confirmed stock or delivery commitment.

Include packaging and repeat-order requirements

For private-label packaging, share label artwork, pack format and the information your team needs on the label. For recurring purchases, include expected quantities and which specifications must stay consistent. Any packaging scope, minimum quantity and timing need confirmation before approval.

Learn about LotusBio and use the wholesale supplier checklist to compare supplier identity, documents and quotation details on the same basis.

Wholesale inquiries from European laboratories

Include your destination country and postal code alongside the product format and quantity. Our European research peptide sourcing guide explains how to compare supplier and dispatch locations, verify the relevant COA, and identify the delivery and receiving details to confirm in a quotation.
