I want to have Ivermectin injectable on hand as I use herbal wormer, but don't want to be caught without a chem if needed. I want to use the injectable as a drench though. Below is the product description sent from my local farm and feed. Is this the correct one? I yes, dosage suggestions? 1cc per 85lbs?
