Bendazole Lab markets fenbendazole capsules under a U.S.-sounding brand name, but our investigation reveals the product is manufactured by a Chinese OEM supplier, the Certificate of Analysis appears to be fabricated in a basic text editor, and Amazon reviews from verified purchasers include alarming reports of wrong molecular structure and zero fenbendazole content. The label itself reads "Distributed by: BendazoleLab, Houston, TX" — but the actual production comes from Xi'an, China.
The Certificate of Analysis provided by Bendazole Lab is not a legitimate lab document. It is a plain text table created in a word processor or spreadsheet — there is no laboratory letterhead, no lab name, no analyst signature, no accreditation number, no testing facility address, and no instrument details. The "certificate" simply lists specifications and results in a generic table format. Any company can produce such a document in minutes. Compare this to a genuine third-party CoA which includes the testing lab's identity, methodology details (HPLC column, flow rate, detector), chromatograms, and a signed analyst report. The Bendazole Lab document has none of these.
The product is manufactured by Xi'an Tian Guangyuan Biotech Co., Ltd., a Chinese company listed on Made-in-China.com that openly offers OEM & ODM Private Label Fenbendazole Capsules at wholesale prices of $1.50–$4.50 per bottle. Their listing explicitly shows the Bendazole Lab branding on the bottles — meaning the same Chinese factory produces bottles with your brand name printed on them to order. The label on the product reads "Distributed by: BendazoleLab, Houston, TX 77379" — a distribution address, not a manufacturing facility. The actual production happens in Xi'an, China.

Verified purchasers on Amazon have left alarming reviews:
"Per an independent lab there is no bendazole at all in this product. Evidence that this is a fraudulent product. Probably cornstarch."
— Debra Bunger, August 2024 (78 people found helpful)
"Recent tests show this is 56% pure by independent 3rd parties. No refunds. Avoid."
— Vie, September 2024 (12 people found helpful)
"Wrong molecular structure. This is not fenbendazole. Amazon needs to ban this company."
— Walt, August 2024 (45 people found helpful)
"Labeled FOR RESEARCH ONLY."

Bendazole Lab is a private-label reseller of Chinese OEM fenbendazole capsules purchased for as little as $1.50 per bottle from Xi'an Tian Guangyuan Biotech. The "Certificate of Analysis" is a self-made text document with no laboratory origin. Multiple verified Amazon purchasers report that independent lab testing found no fenbendazole, only 56% purity, or wrong molecular structure entirely. The product is labeled "FOR RESEARCH ONLY." This is one of the most concerning products in the fenbendazole market — we strongly recommend avoiding Bendazole Lab.
