Genuinely strong testing documentation — multiple named labs, measured mass on the certificates — sitting next to a removed Trustpilot profile and a price that differs by $30 depending on which page you read. Verify the price at checkout and read the certificate for your lot.
Verification score: 6/10 · Independent rating: none confirmed · Lab: Janoshik Analytical · Chromate Labs · ILS-Lab · Researched: 5 September 2026
What checks out
- Names Janoshik, Chromate Labs and ILS-Lab; some reports resolve on lab domains (chromate.org/verify, janoshik.com/tests). source
- Certificates publish measured mass against label (BPC-157 10mg: 10.60mg measured, Janoshik, 13 Mar 2026). source
- 75-product certificate library viewable without an account. source
- Legal entity and address published: Optima Chemical Supply, Inc., Milwaukee, WI. source
What we could not verify
- Trustpilot profile is REMOVED ('goes against our guidelines', read 5 Sep 2026). Third-party directories still show a 4.7/233 figure — that number no longer exists anywhere a reader can check. source
- Lot-to-vial matching relies on a vendor-stated QR system; certificate PDFs do not print a lot number we could read.
- Many basket-item reports are vendor-hosted PDFs rather than lab-hosted.

Rubric breakdown
| 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, Chromate Labs and ILS-Lab named on /lab-results/ |
| ✔ | 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. | Some reports resolve on chromate.org/verify and janoshik.com/tests (others are vendor-hosted PDFs) |
| ✘ | Batch-specific COAs matched to lots
Certificates carry lot numbers that match shipped vials, not one generic PDF. | Not awarded |
| ✔ | Publishes measured net content vs label
COAs state measured milligrams against the labelled amount, not purity % alone. | Certificates state measured mass vs label (BPC-157 10mg: 10.60mg, Janoshik, 13 Mar 2026) |
| ✔ | COAs and pricing viewable without an account
Open the COA library and catalog logged out. | 75-product certificate library and 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. | Not awarded |
| ✘ | No contradictions among its own claims
Compare testing/lab statements across the vendor's own pages. | Not awarded |
| ✔ | Vial sizes stated with prices
Catalog or product pages show milligrams next to every price. | Sizes stated with prices (BPC-157 10mg $85.00 product page) |
| ✔ | 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. | Optima Chemical Supply, Inc. · 436 S Curtis Rd, Milwaukee, WI 53214 — /contact-us/ |
| ✘ | 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. | Not awarded |
