Question 1

What does the purity reading mean on this KLOW (GHK or GHK-Cu/ TB-500/ BPC-157/ KPV) COA?

Accepted Answer

No purity reading is on file for this COA. Some certificates record identity confirmation (correct compound, correct molecular weight) without a numeric purity percentage — check the individual test fields for details.

Question 2

How do I verify this KLOW (GHK or GHK-Cu/ TB-500/ BPC-157/ KPV) COA from Janoshik Analytical is real?

Accepted Answer

To verify this COA is genuine: (1) confirm the issuing lab — Janoshik Analytical — is a real, independently operating laboratory by searching it outside the vendor's website; (2) if the COA includes a verification ID or QR code, use the lab's public portal to cross-reference; (3) check that the lot number on the COA matches the lot number on your order. Merit Verified indexes this result from Janoshik Analytical as a third-party record — the original COA document from the lab is the authoritative source.
