Went to Tractor Supply yesterday to get Ivermectin and it was behind locked glass. There were three different notices plastered to the glass warning the sheeples that it was not suitable for human use, that it was not suitable for treatment for Covid-19, etc. Durvet brand was completely sold out. Supply of all brands of ivermectin with pyrantel (sp?) was good, but only four tubes of Zimecterin brand of ivermectin only paste left. Won't be surprised if, at some point, they make it available only through a vet.
