Joey, Florida Sharkman has a great blog, very detailed for ivermectin paste and other deworming use. I would start there! My wife and I been on iv 1.87 for over two years. ivermectin injection solution taken orally with juice, water whatever is another option. Spend time researching his site, a wealth of info.
