Independent testing Program details to confirm

Independent HPLC testing on every lot

Each lot is sent to an independent laboratory for HPLC analysis. The laboratory's chromatogram and certificate of analysis are filed under the batch and lot number printed on your vial.

  • Independent laboratory, named on every report
  • Lot- and batch-specific certificate of analysis
  • Look up any lot number online

  2. 1955Vincent du VigneaudThe first synthetic peptide hormone
  3. 1958Frederick SangerThe complete amino acid sequence of insulin
  4. 1977Guillemin, Schally and YalowBrain peptide hormones and the radioimmunoassay
