I used Push health. It wasn't cheap, but its pills not paste.
TS is out down here.
How much did it cost? I used Push Health as well, they originally sent the prescription to the local Publix, a prescription at Publix is $165, there is a mom and pop pharmacy that will fill a prescription for $54. The doctor told me to not use the animal paste unless you empty the tube and mix by hand. Undoubtedly when they fill those tubes they are filled with 90% paste and 19% Invermectin. When you use it on a animal, you inject the entire tube. If you squeeze it out in portion, you don't know where in the tube the med is at. This explains why some people are OD'ing.
