Research peptides, verified lot by lot.

Every Lumexa vial carries a printed lot code that links to its own independent certificate of analysis. Purity and identity are confirmed before anything ships.

One standard for every vial

We don't stock a compound until we can document it. That rule shapes how we source, test, pack and ship.

  • Independent testing. A third-party lab, not the manufacturer, runs HPLC and MS on each lot.
  • Lot code on the label. Match any vial to its certificate in seconds.
  • Sealed and protected. Lyophilized, crimp-sealed and boxed against light and impact.
  • Plain packaging. Nothing on the outside says what's inside.
