The paste is measured according to your weight. On the plunger are notches. Each notch represents 50lbs. If you weigh 150lbs, you'd move the plunger up 3 notches for the 150 lb dose. It is quite simple.
I've read that you can't overdose on Ivermectin. The problem was with the Ivermectin that has added medication. Since I weighed 120 lbs at the time of my first dose I used two notches just to start it slow. The next dose I used 3 noches figuring it would average out what I didn't take the first time. I did it this way till I finished the tube.
If I had a choice, I'd take the injection liquid because it is easier to measure the dose with a syringe. With the paste it's a hit and miss unless one wants to weigh the dose on a scale (Too much work for me!)
Thanks!
Aside from the dosage issue, the per cent strength shown mean nothing to us.
