Sample Requirements

  • Minimum 1 vial / 1 mL for HGH Purity & Identity testing (dimer analysis available as an add-on)
  • For each conformity set, submit 2–8 matching vials with the same product, strength, lot/batch, and blend composition — every vial receives full testing
  • Send one dedicated lyophilized vial for endotoxin testing. Liquid preparations are not accepted. Endotoxin alone requires one vial. When combined with other tests, the dedicated endotoxin vial is additional and cannot be shared. Includes one endotoxin test per sample or conformity set; contact us for testing multiple vials for endotoxin.
  • Keep original vial labels. Add the Sample or Conformity Set reference and lot number. Mark the dedicated vial “Endotoxin.”
