Fenben 10 mg per kg is what I used for 5 days every new moon and full moon ,the worms most active period . Carnivores like dogs take 50 mg per kg to 100 mg per kg , but they have much higher tolerances . Herbivores take 10 mg per kg , we are omnivores so we are probably somewhere in between . I did get great results from 10 mg per kg , and treating strongyloides is a long slow process as nothing can effect the encysted ones . Some people have taken higher doses , Fenben has been given to rats at rates at 10000 times the normal dose and half the tested population still lived . Mebendazole is almost identical to fenbendazole ,and the dosage for that was 10 mg per kg for humans . Mebendazole was pulled from the market after discovering it potential use for cancer , after its cousin fenbendazole was keeping rates cancer free when trying to get cancer cells to grow in specimens .I believe it was Hopkins university that was the facility and I did post numerous articles on this subject
