Supply and dispatch
Ask for the proposed batch, available quantity, dispatch location and preparation time. LotusBio’s company location is Guangdong, China; any quotation should identify where that particular supply would be dispatched.
EUROPE / RESEARCH PROCUREMENT
Research peptide sourcing for European laboratories
Comparing a research peptide supplier for a European laboratory or distribution business starts with the product, the batch evidence and the receiving location. LotusBio is based in Guangdong, China. Use this guide to prepare a wholesale inquiry for finished vials or bulk peptide raw materials and review the documents before placing an order.
Which product format should you request?
A wholesale vial request needs the amount per vial, vials per box and number of boxes. A bulk raw-material request needs the total mass, material specification and preferred container size. Keep these formats separate so suppliers can quote comparable requirements.
| Product | Finished-vial route | Bulk-material route |
|---|---|---|
| Retatrutide | RT specifications and public Janoshik records | Retatrutide raw-material inquiry |
| Tirzepatide | TR specifications and public Janoshik records | Tirzepatide API inquiry |
| Cagrilintide | CGL5 / CGL10 specifications and batch checks | Cagrilintide raw-material inquiry |
Catalog pack sizes do not establish stock or a minimum order. Ask the quotation to confirm both for each requested item.
How can European buyers verify a peptide COA?
Use the original report and its identifiers, not a purity claim alone. The public library separates Janoshik laboratory reports, other sample-testing reports and raw-material COAs.
- Identify the sample. Match the product name and supplied form. A raw-material COA and a finished-vial report cover different samples.
- Compare the batch. Check the report number, sample reference and batch or lot against the proposed supply. RT30, TR30 and CGL5 are catalog codes, not unique batch numbers.
- Read the stated tests. Check the method, units and results. Purity and measured content are separate findings; do not infer an unreported test.
- Verify the source. Where an original laboratory verification link is provided, compare it with the displayed report. Request clarification if the batch offered differs.
Retatrutide and Tirzepatide product pages include sample-specific Janoshik records. The public Cagrilintide PDF covers raw material and is not presented as independent finished-vial testing. Follow the full COA review checklist when recording your decision.
What should a quote for a European destination include?
State the actual destination country and postal code. For a laboratory in Germany, Italy, the Netherlands or the United Kingdom, enter that country rather than only “Europe”. Your requested destination helps the team review the product, receiving documents and transport options together.
Delivery and charges
Request the proposed transport service, handling conditions, estimated transit time and which charges are included. Separate preparation time from transit time and flag any required receipt date.
Receiving documents
List the documents and material details your laboratory or receiving team requires. Ask which can be provided for the quoted product and batch, and resolve missing information before approving the order.
A catalog listing does not confirm shipment availability to every country. Destination-specific arrangements and responsibilities need confirmation in the quotation.
Example: a Retatrutide inquiry for a laboratory in Germany
This example is a request template, not an availability statement or minimum order.
- Product and pack
- Retatrutide RT30; 30 mg per vial; 10 vials per box
- Requested quantity
- 2 boxes, with any additional RT sizes listed separately
- Destination
- Germany; add the receiving laboratory and postal code
- Documents
- Ask which report matches the proposed batch and list any additional receiving requirements
- Quotation details
- Confirm availability, minimum quantity, dispatch location, preparation time, transport arrangements and charges
For Tirzepatide, substitute the selected TR code. For Cagrilintide, use CGL5 or CGL10. For bulk raw material, replace the vial and box quantities with your total mass and material specification.
Questions to settle before approving a supplier
Is a supplier for European buyers necessarily located in Europe?
No. Distinguish the supplier’s company location from the dispatch location and your receiving location. LotusBio is a China-based research supplier; confirm the proposed dispatch details in the quotation.
Does one public COA cover every available specification?
No. A report applies to its identified sample and stated testing scope. Confirm the document applicable to the actual batch and format you intend to purchase.
Can packaging be included in the inquiry?
Include label information, artwork, box format and quantities in a private-label packaging inquiry. Packaging scope and timing are confirmed separately.
