03 / The Science

Purity is not a claim. It's a measurement.

Every Erosyn lot is synthesized by solid-phase peptide synthesis, then independently verified by reverse-phase HPLC and mass spectrometry. The Certificate of Analysis — identity, purity percentage, molecular weight, appearance — ships with the vial.
