RPL Peptide is a China-based peptide manufacturer and wholesale supplier focused on research peptides, custom peptide synthesis, bulk production, and OEM/private-label manufacturing for global B2B customers.
Our Background
We were established to support the growing global demand for reliable peptide manufacturing and wholesale procurement.
By integrating peptide synthesis, purification, analytical testing, packaging, and logistics coordination, we provide customers with a streamlined peptide supply solution from production through delivery.
Since 2012, our operations have evolved from small-scale peptide synthesis support to integrated manufacturing and OEM supply programs for international customers.
From custom peptide synthesis and analytical verification to bulk manufacturing and OEM packaging, RPL Peptide provides integrated peptide supply solutions for global B2B customers.
Peptide Manufacturing Workflow
RPL Peptide operates a structured manufacturing workflow designed to support consistent production, analytical verification, and international supply requirements.
Standard Production Workflow
1. Peptide Synthesis
Solid-Phase Peptide Synthesis (SPPS) is used to manufacture peptide sequences according to defined production specifications.
2. Purification Process
Crude peptides undergo purification using preparative HPLC systems to achieve the required purity targets.
3. Analytical Verification
Qualified batches may be evaluated through HPLC purity testing, LC-MS molecular weight confirmation, and internal quality review procedures.
4. Lyophilization & Packaging
Finished materials are processed through lyophilization, vial filling, labeling, and packaging based on product and customer requirements.
5. Documentation & Export Support
Batch records, quality documentation, and export-related materials are prepared to support international distribution and long-term supply programs.
Quality & Traceability
Quality control is integrated into every stage of production, not only final testing.
- Each batch may include:
- Certificates of Analysis (COA) for qualified products
- Raw material verification
- In-process quality control
- HPLC purity verification
- LC-MS identity confirmation
- Batch traceability records
Quality Philosophy
RPL Peptide follows three core principles:
- Consistency – Stable and repeatable manufacturing processes
- Traceability – Documented batch and material tracking systems
- Transparency – Clear analytical data and production documentation
These principles ensure predictable supply performance for repeat procurement programs.
