Fenben lab is a company that has been selling fenbendazole online since 2016. They are also a major distributor of the drug. They distribute to veterinary clinics and directly to consumers worldwide. They are using marketing campaigns to target sick individuals that are looking for a cure to their illness. The product is a 22% fenbendazole powder that comes in either a bottle with a scoop or pre measured capsules. It contains FDA approved excipients which make the drug work deeper and faster. It is fat soluble and needs oil to dissolve but by adding drops of DMSO to it it becomes water soluble and can be absorbed by the body.
The widely used antihelminth agent fenbendazole has been shown to have cytotoxic and antitumor activities in human lymphoma cells in vitro and as solid tumors in SCID mice. These activities are mediated by mechanisms that overlap with those of hypoxia-selective nitroheterocyclic cytotoxins/radiosensitizers and taxanes. However, intensive treatments with fenbendazole in combination with radiation or docetaxel did not alter the growth of EMT6 mammary tumors and did not improve their sensitivity to cytotoxic agents.
Fenbendazole is toxic to helminthes and parasitic worms by inhibiting the polymerization of tubulin, a component of microtubules in cells. These microtubules form part of the cell skeleton and provide structural support and shape. The cytotoxic effects of fenbendazole may be partly due to its pharmacokinetics, which result in low levels of fenbendazole and its active metabolites in tissues relative to the concentrations of fenbendazole and metabolites in gastrointestinal tract secretions. Metabolic similarities and phylogenetic relationships among species within the Gyps genus suggest that other vultures may be susceptible to fenbendazole toxicity. fenben lab fenbendazol
