Question 1

How do I check if a peptide vendor is legitimate?

Accepted Answer

Check whether the vendor has independent, third-party Certificates of Analysis (COAs) on file — not just COAs the vendor generated or hosts itself, but results from a named outside lab. Merit Verified indexes 6,574 independent COAs across 166 indexable vendor pages and derives a single 0–100 Merit Score per vendor from that observable evidence alone: how many independent COAs are on file, which labs ran them, measured purity, and how recent the testing is. No paid placement — a vendor with no COA on file scores as Unscored, not a flattering middle number.

Question 2

How do I verify a peptide COA is real?

Accepted Answer

Confirm the issuing lab is a real, independently operating laboratory by searching for it outside the vendor's own website. If the COA carries a verification ID or QR code, cross-reference it on the lab's own public portal. Check that the lot number on the COA matches the lot number on the product. Merit Verified catalogs COAs as third-party records linked to peptide, vendor, lab, batch, and test date — the original document from the lab remains the authoritative source.

Question 3

Which peptide vendors do independent third-party testing?

Accepted Answer

Merit Verified tracks which vendors have independent COAs on file from outside labs, and from how many labs — lab diversity is a stronger legitimacy signal than a single self-reported test. The directory currently covers 166 indexable vendor pages and 22 independent testing labs; each vendor profile lists its COA count, lab sources, and measured purity history so the evidence — not a ranking or review — speaks for itself.

Question 4

What is Merit Verified?

Accepted Answer

Merit Verified is an independent peptide-vendor verification directory, not a seller. It catalogs third-party COA evidence across vendors and independent labs and derives one auditable Merit Score per vendor from observable data only — no paid placement, no reviews, no pay-to-rank. Merit Verified's brand line is "Look Past the Label": read the evidence a vendor has on file before trusting a label claim.
