I always use this product in my dewormer rotation for my horses. Easy to order and receive. Very great price, too!
Thankyou for an affordable all around good product for worming my horses. I do recommend your ivermectin horse wormer
Over 20 yrs. Ordering from Jeffers. Always a good experience.
I've ordered several different items from Jeffers and I have been very pleased with everything. From tack, shots, and wormers .....I'm very satisfied !!!
"Best price around"
This is the best price around for ivermectin. Love it and horses don’t seem to spit it out at all. Will buy again.
This is a great and very affordable product. When you have more than one horse, worming can get very expensive. This wormier is very affordable and easy to use, horses really like it and it works!
"Luv this "
Fast shipping, great product, my horses love the taste. Thank you jeffers
Super fast shipping. Easy to give to my horses unbridled in the pasture. Thanks!
"Economical and Great Flavor"
Our Percherons like the flavor of Jeffers Ivermectin. (Just wish it came in larger doses).
"Can't beat it!!"
Excellent quality. Great price. Thank you, Jeffers!!
and the mules seem to like it. Few fight me anymore.
"Good worm are"
The Price is Right
"Great Product at reasonable price"
I had a gift card and needed help after logging into the website. The phone call was so helpful, I was relieved to get kind help and my order came in great time. The product does its job well and I so appreciate Jeffers.
"Horses Like It"
Our Percherons like this dewormer. It has a pleasant apple flavor delivered in a gel that our horses like. It’s a fight with other dewormers.
"Horse didn't try to spit it out"
It's Ivermectin. No reason to buy a name brand if it has the same main ingredient. I just bought it because it was cheap but to my surprise my horses took it no problem. They always try to spit out Equimax and Zimectrin. It doesn't smell as "mediciny" as the otherse either. My goal is not to "torture" them with dewormer so if it's cheap and palatable, I'll be buying this for the annual deworming.
