A properly registered European company with a public certificate vault and measured-mass reports, carrying a removed Trustpilot profile, a self-hosted badge that looks like one, and an open question about whether its laboratory is independent. The company's own answer to that question — that ±5–10% deviations are common — is worth reading before you trust the vault.
Verification score: 6/10 · Independent rating: none confirmed · Lab: Liquilabs s.r.o. · Researched: 6 September 2026
What checks out
- Names Liquilabs s.r.o.; the COA Vault lists 91 batches without login, and the sampled BPC-157 5mg report (batch 2026346) states 6.38mg measured. source
- Full company registration published: PARTICLE s.r.o., business ID 47858541, VAT SK2024128172, Lučenec, Slovakia, with phone. source
- Prices verified to the cent: BPC-157 5mg (with mannitol) €31.99, TB-500 10mg (with mannitol) €79.99, 'GLP-3' 10mg €149.99. source
What we could not verify
- Trustpilot profile is REMOVED ('goes against our guidelines', read 5 Sep 2026); several third-party sites still quote a '4.9 from 308' figure. source
- Lab-side verification — the certificate says 'Verify Results Online' but no working Liquilabs lookup was found.
- Whether Liquilabs is independent — a Reddit allegation (shell company, duplicated equipment serial numbers, underdosing) exists only as described in the vendor's own rebuttal; we did not open the thread. source
- Semaglutide, tirzepatide or NAD+ — none found in the catalog.

COAs are hosted on the testing lab's own system or carry a lab-side lookup code. | Not awarded |

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 |

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 |
