Compare quotations on the same basis
Compare the same material identity, specification, total mass, container size and required documents. A packing reference such as 1 kg/bag describes a format; it is not a confirmed minimum order quantity or available stock. Confirm MOQ and lead time in the actual quotation.

How to prepare a bulk raw-material inquiry
Send the exact material name or variant, required total mass, preferred container sizes, target specification and destination country. Include purity and content requirements separately, any required analytical methods, and your requested receipt date. Our team will review availability, MOQ, packaging, lead time and the documents available for the proposed material.
Before approval, match the identity, batch reference and test scope to the quotation. If you require independent testing, agree on the sample, tests and report requirements before dispatch. See our third-party testing information and COA verification guide for document checks.
For company information, visit About LotusBio. If your project also requires finished-vial labels or outer packaging, review the separate private-label packaging service and specify that format in your inquiry.
Bulk raw-material sourcing questions
Does HPLC purity mean the same thing as peptide content?
No. HPLC purity and peptide content describe different measurements. Read the method, units and result for each field on the relevant report; do not substitute a purity percentage for a content result when comparing specifications.
Can I review a COA before placing a bulk order?
Browse available public documents, then identify the material and quantity in your inquiry. Ask which report applies to the proposed batch. A published reference COA is not confirmation that every batch has the same results or that every listed material has independent third-party testing.
What is the MOQ, and can I request kilogram quantities?
State the total mass you require, including kilogram-scale or recurring needs. Available quantities and container sizes depend on the material and current supply. MOQ and lead time are confirmed in the actual quotation; a catalog packing reference is not an order commitment.
Are raw materials quoted as finished vials?
No. Specify bulk material by total mass and container size. For finished vials, use the product catalog and state the amount per vial, vials per box and box count. Request these formats separately so the quotation and documents match the intended supply.
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.

Review identity, quantity basis, COA scope, packaging and repeat-order specifications before comparing a bulk peptide quotation.
Build a bulk-material sourcing request
Choose a material page for identity and documentation checks, then request a quotation using total mass in mg, g or kg. Specify preferred container sizes, destination and any batch-document requirements. Listed packing references and example COA results describe reference information, not a universal MOQ or a specification guaranteed for every batch.
