Verification score: 10/10
Each criterion below is something you can check yourself; evidence lines carry the date we read them.
| Criterion | Evidence |
|---|
| ✔ | Names its testing laboratory
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
Open the COA library and catalog logged out. | Lab reports and sized pricing viewable without an account |
| ✔ | Independent review base (50+ on an external platform)
Check the vendor on Trustpilot or an equivalent platform the vendor cannot edit. | 4.6 / 59 on Trustpilot (verified 5 Sep 2026) |
| ✔ | No contradictions among its own claims
Compare testing/lab statements across the vendor's own pages. | No contradictions found; prices stable across two reads (checked 5 Sep 2026) |
| ✔ | Vial sizes stated with prices
Catalog or product pages show milligrams next to every price. | Sizes stated with prices (BPC-157 10mg $36.00, TB-500 10mg $48.00) |
| ✔ | 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) |

| Independent rating | 4.6 (59 reviews) |
| Testing laboratory | Janoshik Analytical · Vanguard Laboratory |
| Certificates | Names Janoshik Analytical and Vanguard Laboratory; certificates resolve on the lab's own domain (verify.janoshik.com).

Full basket with sized pricing, stable across reads. |
| Caveat | Smallest review base in this batch (59). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT. |

Check it yourself in ten minutes
Open the vendor's certificate library logged out and confirm the lot number on a live product matches a certificate. Look the laboratory up by name and, where a lookup code exists, verify the report on the lab's own site. Read the independent review record on a platform the vendor cannot edit. Find the legal entity and street address on the vendor's own Contact or Terms page. If any of those fail, treat the missing item as unverified — not as disproven.
