Tractor Supply Company

I get mine at the feed store, the im kind but just put a hole in that part, and use it orally of course.

Here as well if this is what you are looking for, but they are often sold out:

I have purchased twice from this company without prescriptions and without problems. There are a few questions you are asked as you place the order, like birthdate and such, but when it gets to the part about a prescription, just skip it. I have purchased ivermectin, HCQ, anti biotics and so forth. The company stays in touch with you regarding your order. I can't speak for anyone else who has used this site and I can't promise you won't have an issue, but I was very happy with their service, prices, timely shipping and products. Yes, over seas, but they are very up front with you about shipping. Hope this helps.
