The oral horse paste or gel in my opinion is safe , it is fda approved and after taking these meds for 1 full year I haven't been this healthy in years . I don't agree in taking the drench style meds for oral consumption when oral meds are easily available in horse stores. The horse paste is coffee flavored and the gel is Apple flavored . Both will give you 1250 pounds of meds for 2 to 4 dollars per tube which is 5 doses for my body weight . Ivermectin pills cost 10 dollars per 3 mg pill and I need 7 per dose and 70 dollars per day would have put me in a hole figuratively and literally as I wasn't working due to severe infections and couldn't afford human meds. The albenza pills cost 125 dollars per 100 mg and I was taking 8 a day . But my blue cross only covered 10000 dollar worth of meds for calendar year except for cancer and I maxed out my account after two weeks. That's why I bought albendazole in animal form for 54 dollars which was over 500 pills made by Pfizer which was the same company that made albenza. My doctor knew my financial and health situation and agreed I had no choice but to use farm meds. Hope this helps , happy hunting , leave no survivors and wish you well.
