OEM Collaboration Process

A five-step workflow that takes your project from first contact to delivered, labeled product.

  1. Requirement discussion

    Share your target peptide, quantity, purity, and packaging needs. Our specialists review sequence feasibility and respond with a technical proposal.

  2. Sample confirmation

    We produce a pilot batch with your chosen formulation and packaging plan; you approve the sample before commercial production begins.

  3. Terms and kick-off

    Confirm technical and commercial terms, sign the supply agreement, and officially start the project with a dedicated project manager.

  4. Production and QC

    Synthesis, purification, lyophilization, filling, and full analytical QC run under batch-record control with QA-reviewed release.

  5. Delivery and support

    Cold-chain international shipping with tracking, complete COA documentation, and after-sales technical support for your customers.
