Inside the lab

Every batch, three times verified.

We run HPLC, mass spectrometry, and endotoxin testing on every release. If a single gate fails, the batch is destroyed — not discounted.
  • Independent ISO-17025 lab partners
  • Batch traceability from synthesis to vial
  • All COAs free to download forever

What researchers are saying.

The COA transparency is unmatched. Every batch we've tested matched their reported purity within 0.3%.

Dr. L. Hartmann Senior Researcher, ETH Zurich

Reliable shipping, consistent quality, and a science team that actually replies. A rare combination.

M. Okafor, PhD Principal, Lagos Biolabs

We switched our entire SPPS workflow to REP Research Lab reagents last year. Reproducibility is up across the board.
