Here is Equimax horse paste, which has 2 effective medications along with titanium dioxide: https://www.durvet.com/wp-content/uploads/2017/12/1EQU022_SDS_1.pdf

This is listed as regular larger particle titanium dioxide that is way less dangerous than the nanoparticle version. I'm skeptical, however.

Here is the Durvet Apple Flavor Ivermectin, which comes in non-flavored as well: https://www.durvet.com/wp-content/uploads/2017/09/Ivermectin-Paste_Bimeda_112015_SDS.pdf

It's highly likely to be used as part of its listed "proprietary component A, B, and C". Only reasons for hiding such ingredients is either toxicity or trade secrets due to competition. Horse paste is preferred by horse owners because of ease of handling, application, taste, and overall convenience. So the process of making effective paste may be a necessary secret. Since it's not marketed towards humans, they can have proprietary ingredients and less strict regulations.

Titanium dioxide is widely used. Commercial toothpaste is a toxic concoction of titanium dioxide along with artificial sweeteners, carrageen, fluoride, and much more. Also used in candy, beauty products, deodorant, etc.

Just remember that "they" wish us to sacrifice our health for convenience everyday. Get a boostahs so that you can live life again!

If you think that they wouldn't hurt animals, well... commercial dog bones are actual toxins, vegan foods for pets, etc.

Again, not all people are blessed with affordable and available ivermectin. Take what you can get when you really need it. Otherwise seek better options for ivermectin! Good luck friend!
