The process

About our testing methodology.

Independent testing is the only way to make research results reproducible. Every Lembas batch passes two checkpoints before it ships.

  1. 01

    Raw material HPLC

    Every raw material is analyzed by HPLC before synthesis begins, confirming the starting sequence.

    Before synthesis
  2. 02

    Third-party HPLC

    Samples from each finished batch go to an independent, accredited U.S. lab for a second purity analysis.

    ≥ 99% baseline
  3. 03

    Mass spectrometry

    LC-MS confirms the molecular weight matches the target peptide.

    Identity match
  4. 04

    Published + shipped

    The COA and chromatogram are posted to this library and included with every order.
