Short answer: legitimate, with caveats. As of 5 September 2026, Optima Supply scores 6/10 on our published verification rubric, has no independently viewable review record (its Trustpilot profile has been removed), and names its testing laboratory (Janoshik Analytical · Chromate Labs · ILS-Lab). There are real verification gaps, listed below, that a careful buyer should weigh before ordering.
Verification score: 6/10
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, 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 |
The record, in one place
| Independent rating | Trustpilot profile removed |
| Testing laboratory | Janoshik Analytical · Chromate Labs · ILS-Lab |
| Certificates | Names Janoshik, Chromate Labs and ILS-Lab; some reports resolve on lab domains, and certificates state measured mass against label (BPC-157 10mg: 10.60mg measured). 75-product certificate library viewable without an account. Legal entity and address published: Optima Chemical Supply, Inc., Milwaukee, WI. |
| Caveat | Trustpilot profile removed for guideline violations (read 5 Sep 2026) — no independent review base exists, and the site still displays a review badge without disclosing the removal. BPC-157 10mg is $85 on its product page and $55 on the homepage. Lot-to-vial matching relies on a vendor-stated QR system we could not verify; many basket reports are vendor-hosted PDFs. |

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.
