How we make sure of it

What we can prove about this vial.

Not what we will build in 2028 — what happens to this preparation, today.

  1. Tier-1 APITier-1 API only — sourced from U.S. and allied producers, with auditable COA, chiral panel and residual-solvent data on every lot.
  2. IdentityConfirmed by LC-MS/MS against the reference sequence.
  3. PotencyHPLC against a 99.0% specification.
  4. EndotoxinLAL testing below USP limits for an injectable.
  5. SterilityUSP <71>, with USP <788> particulates.
  6. TraceabilityVial-level serialization, so a lot number resolves to its own release panel.
Look up a lot number

Our own Missouri synthesis plants come online in 2028 and 2029. Until then the API is sourced from Tier-1 U.S. and allied producers and tested on arrival. We describe that honestly rather than implying we already make it.
