Independent RUO Lab Verification, Purity Benchmarking & Vendor Audits.
Lab-verified audits first — then the true price per mg and active promo codes, so you know what each milligram really costs.
The audit standard
A vendor's marketing says "99% pure". We grade the certificate behind it — who tested it, what they found, and whether it's still the batch on the shelf.
New to COAs? Why a PDF alone isn't proofHPLC/MS certificates from outside labs. Full points only when the report can be looked up on the lab's public portal (Janoshik task ID / QR, MZ Biolabs, Freedom Diagnostics Search Code).
Pass · 3rd-party · independently verifiable
Reported purity and the measured milligrams in the vial versus what the label claims.
Pass · ≥ 99.0% · within ±5% mg
Lead, arsenic, cadmium and mercury panel plus LAL endotoxin screening.
Pass · All four metals + LAL pass
The certificate must match a currently sold batch — not a COA from last year.
Pass · Tested < 60–90 days
Then: the economic transparency layer
Once a batch clears the lab checks, we show the honest economics: price per unit, effective price after active promo codes, and disclosed affiliate discounts.
Every listing is converted to dollars per milligram — and per measured mg, not the label — so a 5mg, 10mg and 30mg vial compare like for like against the compound's market median.
When a vendor has a live promo code, the discounted $/mg sits right next to the base price, so you see what you'd actually pay.
Codes are checked before they're marked verified, copy in one tap, and affiliate links are always disclosed. Discounts never change a grade — grades use the base price.

Composite Audit Score
Every batch is scored out of 100 and graded on a fixed scale, so a grade only moves when the vendor's own lab reports do. A separate rank shows where each vendor stands among everyone we audit. A+ needs 90+ points plus endotoxin testing on every batch, fresh certificates and an independently verifiable lab. A failed heavy metals or endotoxin panel caps the grade at C.
