Fenbendazole High Dosage? Any advice?

Hi, I am trying Moxidectin 250lbs each day+Fenbendazole 2g each day. It helped with the skin itchiness, but I am wondering if I can go higher to actually kill the worms. Anybody tried even higher dosage eg. 3 grams? I know the dog can use 50mg/kg each day.

PS. The Fenbendazole is really expensive in China even for the animal pills. I am thinking to get the pure Fenbendazole chemical to make capsules by myself. Tweet
