Handled like it matters

Every vial is filled, sealed and stored under controlled conditions, then pulled for third-party testing before it is ever listed. What arrives at your bench is what the certificate says it is.

  • Cold-chain from fill to doorstep
  • Batch number on every label, traceable to its COA
  • Sealed under inert gas, never repackaged
