I’ve used the “horse paste”. The weight scale works pretty good for dosing. I’ve got some for my horses and they don’t mind sharing...

Does NOT taste like apples, though!
I’ll add this: I’ve got a friend with a sheep ranch. They have to worm up to 3,000 sheep with the stuff. They use the liquid form and try not to get it on their hands but they always do. They say they can taste it in their mouth afterward because it is absorbed thru the skin. During the COVID Year of Fear Porn, they just smeared some of the liquid on their hands...
There may well be some sort of medical issue that could make it a bad idea. Having already tried it myself, I know I don’t have a reaction. Others may but that is true of almost any supplement.
But yeah, the horse paste tastes AWFUL! Now I know why my horses try to spit it out!
