The lab is identified by name on the vendor's site; you can look it up and contact it. | Janoshik Analytical named on product pages; Vanguard Laboratory listed for 18 certificates on /lab-reports/ |
| ✔ | Certificates verifiable at the lab, not just the vendor
COAs are hosted on the testing lab's own system or carry a lab-side lookup code. | Certificates resolve on verify.janoshik.com (e.g. report #100942, BPC-157 10mg) |
| ✔ | Batch-specific COAs matched to lots
Certificates carry lot numbers that match shipped vials, not one generic PDF. | Dated batch codes per product (e.g. PG-2451, 22 Jan 2026) |
| ✔ | Publishes measured net content vs label
COAs state measured milligrams against the labelled amount, not purity % alone. | Vanguard Laboratory PDF for lot PG-5101 (TB-500 5mg) reports 4.92mg measured vs 5mg, 99.30% purity — read 6 Sep 2026 |
| ✔ | COAs and pricing viewable without an account

| ✔ | Publishes a legal entity and street address
The company's registered name (LLC, Inc., s.r.o. …) and a street address appear on the vendor's own Contact, About or Terms pages — not only a brand name, a city, or hidden page markup. | Plainview Commerce LLC · Tampa, FL street address, EIN and sales-tax number on the refund policy |
| ✔ | No misleading trust signals or buyer-protection workarounds
Compare any on-site review score or badge with the independent platform; check whether the vendor only takes, or pushes you toward, payment rails you cannot dispute; check FDA and BBB records. Awarded unless one of these is on record. | No on-site review badge contradicting the independent record; card payment accepted; no regulator action found (checked 6 Sep 2026) |
