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. | Liquilabs s.r.o. printed on certificates |
| ✘ | 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. | Not awarded |
| ✔ | Batch-specific COAs matched to lots
Certificates carry lot numbers that match shipped vials, not one generic PDF. | Certificate vault lists batch numbers (e.g. PO-2026346) |
| ✔ | Publishes measured net content vs label
COAs state measured milligrams against the labelled amount, not purity % alone. | Certificate reports 6.38mg measured vs 5mg label (BPC-157 5mg with mannitol) |
| ✔ | COAs and pricing viewable without an account
Open the COA library and catalog logged out. | Certificate vault 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 5mg €31.99, TB-500 10mg €79.99) |
| ✔ | 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. | PARTICLE s.r.o. (ID 47858541) · Kolonáda 4490/18, Lučenec 984 01, Slovakia — /content/4-company-information |
| ✘ | 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 | Liquilabs s.r.o. |
| Certificates | Names Liquilabs; a 91-batch certificate vault viewable without an account, with per-batch reports stating measured content (BPC-157 5mg batch 2026346: 6.38mg). Full Slovak company registration published: PARTICLE s.r.o., business ID 47858541, VAT SK2024128172, Lučenec. Sized EUR pricing throughout. |
| Caveat | Trustpilot profile REMOVED, while the homepage shows a self-hosted '4.9/5 from 529 reviews' badge styled like a trust widget. A public dispute over whether its lab, Liquilabs, is independent — the vendor's own rebuttal concedes 'minor deviations (±5–10%) are common'. Prices in EUR, not comparable in our USD index. Retatrutide sold as 'GLP-3' (CAS printed). No semaglutide, tirzepatide or NAD+. |

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.
