How to Read a KGLOW Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For KGLOW, the informative checks are not the same as for a generic short peptide.
In plain English
Look for all four ingredients identified with a ratio near 50:10:10:10. One specific thing to check: KPV is very small and comes off the testing column almost immediately, so confirm the method genuinely separated it rather than losing it in the noise at the start.
What KGLOW actually is
KGLOW — also written KLOW — is GLOW with one addition. It contains GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg and KPV 10 mg, making 80 mg in total. KPV is a very short three-part molecule taken from a natural hormone, studied for calming inflammation in research models.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥98% purity, with a Certificate of Analysis on every order. Ships across Canada.

What to check on the COA
A meaningful KGLOW COA resolves all four components with a stated ratio approximating 50:10:10:10 by mass. Copper content should be confirmed separately for the GHK-Cu component. KPV is small and elutes early on RP-HPLC, so confirm the method actually resolves it rather than losing it near the solvent front.
Ratio deviation from 50:10:10:10, free GHK peptide, oxidised TB-500, and per-component synthesis impurities.
