HPLC purity 99.93%: in the lab's chromatogram, 99.93% of the detected peak area belongs to the Glow peak and the remaining 0.07% to other components the method detected.
Accumark Labs printed a purity specification of > 98.0% and marked the result "Conforms".
Measured content of GHK-Cu: the amount Accumark Labs quantified in the vial it received (58.661 mg), with a per-compound HPLC purity of 99.917%. It is a measurement of this sample, not a label figure.
Measured content of BPC-157: the amount Accumark Labs quantified in the vial it received (12.993 mg), with a per-compound HPLC purity of 99.905%. It is a measurement of this sample, not a label figure.
Measured content of TB500 (17-23 Fragment): the amount Accumark Labs quantified in the vial it received (14.201 mg), with a per-compound HPLC purity of 99.992%. It is a measurement of this sample, not a label figure.
Identity: GHK-Cu, BPC-157, TB500 (17-23 Fragment), "Conforms". Accumark Labs's identity test matched the sample to GHK-Cu, BPC-157, TB500 (17-23 Fragment).

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.
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.
