Hello, I have had the same problem for 19 mths can u tell me what PinX is made from as I am in Australia and not sure of this product. I presume IVM is just the horse paste as Dr's will only give me a limited amt. have had Albendazole & Iver previously as I have a hyper infection that is systematic throughout my body. I presume scattered roundworm but never had positive results. Tis Zippedo
