Beyond Purity

Tested Four Ways

Purity is the baseline. Every batch clears four independent checks before it ships.

Endotoxin Tested

LAL testing on every lot to verify endotoxin levels fall within research-safe limits.

Sterility Verified

Independent sterility assays confirm each batch is free of microbial contamination.

Heavy Metals Screened

ICP-MS screening ensures heavy-metal content stays below detectable research thresholds.

Batch Consistency

Every lot is HPLC-verified for identity and ≥99% purity, lot after lot.

  • Independent third-party COA for every lot
  • ≥99% HPLC-verified identity & purity
