One lab, one standard.

One synthesis run per lot

Lots are never pooled across campaigns, so the report you read describes the exact vial you receive.

Independent laboratories

Purity, identity and safety assays are run by laboratories with no stake in the result.

Documentation on file

Each product page carries its lot number, purity figure and the report itself, downloadable before you order.

Every peptide you need, tested before it ships.
