We walk through how to verify fenbendazole quality when formal oversight is missing, focusing on scientific testing that proves identity, purity, and safety. Practical steps show how to read a COA, spot red flags, and demand USP‑aligned standards and third‑party results.

• why purity targets of ≥98–99% matter for safety and efficacy
• three impurity types fillers, synthesis byproducts, environmental metals
• how HPLC and UPLC quantify assay and total impurities
• why GCMS finds residual solvents and enforces USP 467 limits
• identity checks using NMR, IR, and LCMS to prevent mislabeling
• heavy metal and microbial testing thresholds and methods
• USP impurity limits and cGMP process control expectations
• a step‑by‑step COA audit for batch match, methods, and numeric results
• warning signs of fake or weak COAs and risky suppliers
• veterinary formulations vs API concentration and excipient concerns
