How to read this Glow certificate

A Certificate of Analysis is the testing lab's record of what it measured in a sample. Here is what each line on this certificate means:

  • Identity: GHK-Cu, BPC-157, TB500 (17-23 Fragment) — Conforms. The lab confirmed the sample is the named compound.
  • GHK-Cu — measured content: 58.661 mg (purity 99.917%). The amount of the compound the lab measured in the vial. Several values mean several vials were tested.
  • BPC-157 — measured content: 12.993 mg (purity 99.905%). The amount of the compound the lab measured in the vial. Several values mean several vials were tested.
  • TB500 (17-23 Fragment) — measured content: 14.201 mg (purity 99.992%). The amount of the compound the lab measured in the vial. Several values mean several vials were tested.
  • Purity (HPLC): 99.93% — Conforms (spec > 98.0%). HPLC separates the sample into its components; purity is the share of the main compound. Where several values are listed, each is a separate vial.

To confirm these figures, open the Accumark Labs report linked on this page and check that its report ID is PT3S-35FM.

HPLC testing methodology

High-Performance Liquid Chromatography (HPLC) is the standard analytical technique used to verify peptide purity. Peptide labs typically run reverse-phase HPLC with UV detection. The chromatogram displays retention time on the x-axis and UV absorbance on the y-axis. The area under each peak corresponds to compound quantity. Purity is calculated as the target peak area divided by total peak area, expressed as a percentage. A purity of 98% or above is the usual research-grade threshold.

Storage & handling

Research peptides should be stored lyophilized (freeze-dried) at -20°C or below until ready for use. Avoid repeated freeze-thaw cycles. Upon reconstitution, store at 4°C and use within 30 days. Keep away from direct light and moisture. All handling should be performed under sterile research conditions by qualified personnel following applicable laboratory safety protocols.
