Why Premier Bio Labs

Built for Researchers Who Demand Proof

We don't ask you to trust us. We give you the data to verify us. Every batch. Every compound. No exceptions.

📊

Published Chromatograms

Most suppliers give you a purity number. We publish the full HPLC chromatogram — every peak, every impurity, full transparency.

🧬

HPLC + Mass Spec Verified

Dual-method verification on every batch. HPLC confirms purity. Mass spectrometry confirms molecular identity. No shortcuts.

🏗️

FDA-Registered Facilities

Manufactured under current Good Manufacturing Practices in cGMP-certified facilities. Full chain-of-custody documentation.

🔍

Lot Traceability

Every vial traces to its production batch with matching COA. Reorder the same lot number for study continuity.

🏢

Institutional NET-30

Qualified institutions get NET-30 terms, forecast-based inventory holds, and blanket POs for larger research programs.

❄️

Cold-Chain Integrity

Validated temperature control from storage through delivery. Products held at -20°C with tamper-evident, cold-chain packaging.
