1. Information We Confirm Before Quotation
Before we review a bulk custom order, the buyer usually provides the product name or custom formulation, final product form, target specification, required purity level, packaging requirements, label requirements, order quantity, destination country, required documentation, and expected timeline. Buyers can also review our custom peptide synthesis support before sending a project file.
This first review is not paperwork for appearance. It helps our team check feasibility, production planning, packaging options, and logistics conditions before both sides spend time on a quotation that may not match the real project.
2. Product, Quantity and Destination Review
After receiving the project information, we review the product requirements, order quantity, packaging format, and destination country together.
Before production moves forward, we also ask whether the buyer has import or clearance capability. If not, we review whether a special-line or DDP route is available for the destination country.
Delivery routes depend on product type, destination country, shipment volume, and current logistics conditions, so logistics feasibility is checked before final confirmation.
DDP or special-line delivery may be reviewed for selected destinations, including USA, Canada, Australia, New Zealand, Mexico, UK, Japan, Singapore, Hong Kong, Malaysia, Thailand, Vietnam, Philippines, UAE, Saudi Arabia, Oman, Israel, Brazil, and Uruguay. For other countries, route review is required before confirmation.
General delivery time is not publicly promised. Shipping timeline is reviewed by destination country and route availability.
3. Specification, Formula and Packaging Confirmation
Before production, we confirm the agreed specifications with the buyer. This may include product form, purity requirements, packaging style, project-specific container format, label content, and documentation requirements.
Packaging options may include 3ml, 5ml, and 10ml vial formats for lyophilized powder projects. Single-chamber and dual-chamber cartridge formats may also be reviewed for liquid-format packaging projects.
Label support may include product name, molecular weight, purity, batch number, production date, and expiry date. Vial labels and outer boxes are reviewed before production when the project requires customized packaging.
For batch review, documentation may include batch-specific COA, peptide purity, molecular weight confirmation, peptide content, endotoxin test when required, microbial limit test when required, moisture, residual solvents, and impurity profile. Buyers can review our COA, HPLC and MS documentation approach before confirming their document list.
Packaging and label requirements must be confirmed before production, not after the product is finished. Once these details are approved, we prepare the production formula and packaging plan based on the buyer's confirmed requirements.

| Bulk Production | Production schedule, batch records, project requirements | Bulk batch prepared under confirmed requirements |
| Packing Confirmation | Packing photos, carton count, carton size, shipment preparation details | Packing file before balance payment settlement |
| Shipment Coordination | Logistics route, dispatch timing, tracking updates when available | Shipment follow-up until agreed delivery stage |
5. Sample Preparation Before Bulk Production
For peptide projects, sample preparation should match the raw material batch intended for bulk production. A sample made from a different batch may not represent the final order.
Because sample preparation uses project-specific raw material and packaging settings, it is arranged after the production agreement is confirmed.
This approach keeps the sample review connected to the real bulk project instead of using an unrelated reference batch.
6. Sample Testing and Third-Party Review
After the sample is completed, the buyer may arrange independent testing through a third-party laboratory they trust.
If the buyer does not already have a testing partner, we can provide available testing information for reference. The final choice of laboratory can be made by the buyer based on their own verification standards.
For first-time cooperation, this gives the buyer a practical review point before bulk production moves forward.
Third-party testing usually takes 5-7 days after sample receipt. The testing scope is confirmed according to product type, document requirements, and the buyer's review needs.
7. Bulk Production Timeline
For single-product orders under 50,000 units, the typical production period is 10–12 days after the sample testing result is approved.
Timing is checked against the product type, packaging format, label requirements, testing requirements, raw material availability, production schedule, destination country, and logistics planning.
For orders over 50,000 units, the production period is usually 15-18 days. Complex or sensitive peptide projects require raw material review before timeline confirmation.
For larger or more complex custom projects, we confirm the production timeline separately before order confirmation.
8. Packaging, Label and Carton Information
Packaging should be confirmed before production starts. If the buyer requires customized labels, the label content, design file, product name, batch format, and other packaging details should be approved before production.
Carton information and packing details are provided after production is completed and before balance payment settlement. This may include packing quantity, carton count, carton size, and shipment preparation details.
9. Our Delivery Standards

10. What We Provide Before Shipment
Depending on the project, we may provide production confirmation, batch documentation, sample or packaging reference, label confirmation, packing photos, carton information, logistics route confirmation, and shipment coordination. If you already have a project file ready, you can send a B2B RFQ for review.
The buyer provides product requirements, packaging requirements, and logistics expectations. Our team coordinates the production and delivery details based on the confirmed project file.
11. Shipment Follow-Up
After shipment, we continue to follow the logistics status and provide updates when available.
For international B2B orders, shipment follow-up matters because delivery time can be affected by customs processing, local delivery arrangements, route changes, and destination-country conditions.
We keep communication open until the shipment reaches the agreed delivery stage.

FAQ: Bulk Custom Peptide Orders
What information should buyers provide before requesting a quote?
Buyers should provide product name or formula, quantity, product form, target purity, packaging requirements, destination country, required documentation, and expected timeline.
Do you prepare samples before bulk production?
For bulk custom projects, sample preparation is usually arranged after the production agreement is confirmed. The sample should match the raw material batch intended for bulk production.
Can buyers arrange third-party testing?
Yes. Buyers may arrange independent testing through a third-party laboratory they trust. If needed, we can provide available testing information for reference.
How long does bulk peptide production usually take?
for single-product bulk orders under 50,000 units.
For orders over 50,000 units, the production period is usually 15-18 days. Complex or sensitive peptide projects require raw material review before timeline confirmation.
Do peptide suppliers provide batch-specific COA?
Yes. For confirmed B2B orders, batch-specific COA can be provided according to the project requirements.
Depending on the product and testing arrangement, the documentation may include peptide purity, molecular weight confirmation, peptide content, moisture, residual solvents, impurity profile, HPLC profile, MS confirmation, endotoxin test, and microbial limit test when required.
Can buyers test peptide samples before placing a bulk order?
Yes. Buyers can test peptide samples before bulk production, but the sample should come from the current raw material batch intended for the final production.
However, sample testing does not replace final batch testing. After the bulk finished products are produced, the finished batch should be tested again because every production batch may show small differences in analytical results.
For this reason, sample testing is used for preliminary verification, while final batch documentation is based on the actual finished production batch.
Do you sell research products to individual consumers?
No. Aurchain Biotech focuses on qualified B2B customers. Research products are supplied for laboratory research use only and are not intended for personal consumption.
