Overview

Oxi Lab (Fenbencap) has been selling fenbendazole on Amazon since 2023 and has built a decent reputation with positive customer reviews. However, a closer look at the company reveals significant transparency issues: a self-made certificate with no lab origin, an entirely Ukrainian-language website including legal documents, and a web developer based in Kyiv — all pointing to Ukrainian origins despite no clear disclosure of this to U.S. customers.

Transparency Concerns
1. Self-Made Certificate of Analysis

The Certificate of Analysis displayed on the Oxi Lab website appears to be created in a text editor or Excel spreadsheet. There is no independent laboratory name, no analyst signature, no lab accreditation number, no testing facility address. It lists a batch of 200KG and test results, but there is no way to verify who performed the testing, when, or where. A certificate without identifiable lab origin confirms nothing.

2. Entirely Ukrainian-Language Legal Documents

The Oxi Lab website's User Agreement ("USER AGREEMENT") is written entirely in Ukrainian, referencing Ukrainian law, Ukrainian consumer protection statutes, and the Ukrainian internet domain www.onigiri.com.ua. The document mentions delivery via Bolt, Uklon, and Glovo — Ukrainian delivery services. The Privacy Policy and all legal pages follow the same pattern. For a company selling to U.S. Amazon customers, this is a clear indicator of Ukrainian origin.

3. Ukrainian Web Developer

The website footer credits WebAtom — a web development studio based in Kyiv, Irpin, Bucha (Ukraine), offering "turnkey website creation". Their phone number is a Ukrainian mobile (+063). This further confirms the Oxi Lab operation is based in Ukraine.

Summary

Oxi Lab delivers a product that Amazon customers generally like — and that counts for something. But the company operates with minimal transparency: a certificate nobody can verify, legal documents in a language their customers can't read, and a clear Ukrainian operational base that is never disclosed. The product may be fine, but the company behind it remains largely opaque.
