Question 1

What does the purity reading mean on this Epithalon 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 Epithalon COA from Vanguard Laboratory is real?

Accepted Answer

To verify this COA is genuine: (1) confirm the issuing lab — Vanguard Laboratory — 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 Vanguard Laboratory as a third-party record — the original COA document from the lab is the authoritative source.

Question 3

Is Certified Peptides a legitimate peptide vendor?

Accepted Answer

Merit Verified has a vendor profile for Certified Peptides with independent COA evidence on file. A COA on file is not an endorsement — it means this specific lot was independently tested.
