Update on my own ivermectin routine:
I had previously filled 2-3 gelatin capsules at a time with the yellow apple-flavoured ivermectin horse/goat jelly. When I bought more, it was a different brand and I didn’t realize it was a white paste, like toothpaste. I pre-filled 2 capsules and the one I didn’t use right away got soft and mushy. This had never happened with the yellow jelly version. I was able to swallow it anyway, but I know not to pre-fill it again if I’m using the white paste.
That means there is water in the white paste. Water dissolves the gelatin capsule.
