ShiLai™ Healthcare — Peptide Manufacturer & Retatrutide OEM

Contract Development & Manufacturing

Peptide CDMO Services: From Sequence to Finished Product

ShiLai™ Healthcare is a specialist peptide CDMO providing end-to-end contract development and manufacturing services — custom synthesis, lyophilization, pre-filled pen filling, dual-cartridge systems, analytical testing, and private-label packaging — for pharmaceutical distributors, research organisations, and brand owners worldwide.

What Is a Peptide CDMO?

A Contract Development and Manufacturing Organisation (CDMO) provides outsourced pharmaceutical manufacturing services to companies that do not operate their own production facilities. A peptide CDMO specialises in the synthesis, formulation, filling, testing, and packaging of peptide-based products on behalf of clients.

For distributors, brand owners, and research organisations, partnering with a peptide CDMO eliminates the capital cost of in-house manufacturing while providing access to specialist synthesis expertise, analytical infrastructure, and scalable production capacity. ShiLai™ Healthcare operates as a full-service peptide CDMO with particular depth in injectable delivery systems — pre-filled pens, dual-cartridge pens, and lyophilized vials.

CDMO Service Scope

Custom Peptide Synthesis

Solid-phase peptide synthesis (SPPS) for research-grade and commercial-scale peptides. Fmoc and Boc chemistry available. Sequences from 2 to 50+ amino acids, including modified, cyclic, and conjugated peptides.

Lyophilization & Vial Filling

Freeze-drying services for peptide bulk drug substance and finished vials. Lyophilized vials offer extended shelf life and cold-chain flexibility. Available in 2mg, 5mg, 10mg, and custom fill weights.

Pre-Filled Pen & Cartridge Filling

Aseptic filling of pre-filled injection pens and dual-cartridge pen systems. Suitable for peptides requiring precise dosing and patient-friendly delivery formats. OEM and private-label configurations available.

Analytical Development & QC

In-house RP-HPLC purity analysis and LC-MS identity confirmation for every batch. Method development, specification setting, and full COA documentation. Independent batch release before shipment.

Packaging & Private Label

Custom packaging design, private-label printing, and branded kit assembly. Suitable for distributors and brand owners requiring finished, market-ready product. MOQ and lead time discussed per project.

Project Management & Regulatory Support

Dedicated project manager assigned to each CDMO engagement. Batch records, COA documentation, and quality agreements available for partners with regulatory filing requirements.

The ShiLai™ CDMO Process

01

Initial Enquiry

Submit your peptide sequence, target specifications, delivery format, and estimated volume via WhatsApp or email. We respond within 24 hours.

02

Feasibility & Quotation

Our technical team reviews the project scope, confirms feasibility, and provides a detailed quotation covering synthesis, testing, filling, and packaging.

03

Project Agreement

A project agreement and quality agreement are signed. Raw material sourcing and synthesis scheduling begin upon receipt of deposit.

04

Synthesis & Manufacturing

Peptide synthesis, purification, lyophilization or liquid filling, and packaging are carried out according to agreed specifications and timelines.

05

Analytical Testing & Release

Every batch undergoes RP-HPLC purity analysis and LC-MS identity confirmation. A Certificate of Analysis is issued before shipment.

06

Shipment & Documentation

Finished product ships with full batch documentation. Cold-chain logistics arranged where required. Tracking provided upon dispatch.

Quality Assurance & Batch Traceability

Every batch manufactured by ShiLai™ Healthcare is assigned a unique batch number at synthesis and tracked through to the Certificate of Analysis (COA) and shipping documentation. Analytical testing — RP-HPLC purity and LC-MS identity — is performed in-house on every batch before release.

CDMO partners requiring batch manufacturing records (BMRs), quality agreements, or additional documentation for regulatory submissions can request these as part of the project agreement.

Frequently Asked Questions

What is the minimum order quantity for CDMO projects?

MOQ depends on the peptide, delivery format, and project scope. Contact ShiLai™ Healthcare via WhatsApp with your project details and we will confirm feasibility and minimum quantities.

Can ShiLai™ Healthcare synthesise a custom peptide sequence not in your catalogue?

Yes. Custom sequences are evaluated on a project-by-project basis. Submit your sequence, target purity, quantity, and delivery format and our technical team will assess feasibility and provide a quotation.

What analytical testing is included in the CDMO service?

Every batch includes RP-HPLC purity analysis and LC-MS identity confirmation as standard. Additional testing (endotoxin, residual solvents, water content, etc.) can be arranged on request.

Do you provide batch manufacturing records (BMRs) for regulatory submissions?

BMRs are available to qualified CDMO partners under a signed quality agreement. Discuss your documentation requirements at the project agreement stage.

What is the typical lead time for a CDMO project?

Lead time depends on peptide complexity, delivery format, and order volume. Standard catalogue peptides in pre-filled pen format typically ship within 3–6 weeks from project agreement. Custom sequences require additional development time.

Can you handle cold-chain shipping for finished product?

Yes. ShiLai™ Healthcare arranges cold-chain logistics for temperature-sensitive peptide products. Shipping conditions are confirmed at the project agreement stage.
