I asked Bob this:
***From your knowledge, is the veterinary Fenbendazole just as good as the human expensive kind?***
His answer:
While I have not done the pharmacological comparison, my understanding is that they are identical. It is the veterinary formulation that has been used against cancer in the literature. It is dismaying that the company that took control of mebendazole schemed to inflate the price of an old generic medicine - probably knowing that the formulation was about to become famous as an anti-cancer therapy.
