Manufacturing Depth: More Than a Catalog
Behind every vial is an integrated manufacturing chain — from amino acid procurement to final QC release. Here's what that actually means for your supply chain.
In-House Peptide Synthesis
We operate solid-phase peptide synthesizers (SPPS) at production scale — no outsourcing to third-party labs. From Fmoc-protected amino acid procurement through cleavage, purification, and lyophilization, every step happens under one roof. This eliminates the 2-4 week delays common with contract manufacturing and gives us direct control over quality at each stage.
Multi-Layer Quality Control
Every batch passes through three QC gates: (1) in-process HPLC monitoring during purification, (2) final product release testing with ≥99% purity threshold, and (3) pre-shipment documentation review. Raw data — not just the COA summary — is archived by batch number and available on request. This isn't a checkbox exercise; it's how we've maintained quality consistency across 2M+ vials.
Batch Traceability & Documentation
Each vial carries a unique batch-traceable serial number that maps to: raw material lot numbers, synthesis date and operator, HPLC chromatogram, MS spectrum, and final QC sign-off. For OEM and private-label customers, this traceability extends to your branded batch numbers — your customers see your label, but the quality trail leads back to our manufacturing records.
