Pardon the ignorant question but how do you take this and where did you get the syringe?
It is manufactured that way. Buy some tubes from Big Dee’s Tack and Vet Supply at $6 a tube.
I weigh 250 pounds so I take 5 notches worth the first of every month. The horse Ivermectin comes in a tube. That is the plunger the tube comes with.
