Solid-phase peptide synthesis at a cGMP-certified partner facility. Every reaction batch is logged with full traceability to raw material lot.
Internal HPLC-UV and LC-MS confirmation. If purity is below 98.5% the batch is discarded — not re-purified, not blended, discarded.
A representative sample is shipped to an independent lab (Janoshik Analytical or Auxilium Pharma Labs) for blind verification.
Approved batches are lyophilized, sealed under inert gas, and stored at −20°C until dispatch.
Vacuum-insulated container sized to weight and destination zone. Temperature data logger included on shipments over $400.
