"I’ve tried this for purposes beyond horses. My dogs actually like it too! Just make sure to calculate the dosage correctly if using it differently."

"I don't use this product frequently, just once a year on my pasture horses. I also give it to mares before foaling and to new arrivals. I typically wait until they are a year old before giving it to foals."

"This wormer was recommended by my vet. It's a fantastic product and comes at a great price."

"After an unusually wet season, my goats tested positive for barber worms for the first time. I started using this product, and it cleared up the issue quickly. I give one notch for each goat."

"I’ve been using this product for years, and it always does a great job!"

"This is a fantastic product! The horses love it, and it comes with fast delivery at the best price!"

"I found this product to be very effective in worming my tortoises. It was also economical. I used a gram scale to measure the medicine accurately. After weighing my tortoise, I determined the right dosage size, about the size of a Tic Tac for my 20-pound desert tortoise. It requires about three doses, spaced ten days apart, to be really effective."

"I decided to give this a try for my big lab after hearing good things. So far, he doesn’t seem to mind it at all. I’m hopeful that the small lump he has will disappear after a few weeks of treatment for parasites."

"I had a bit of a situation with three cats passing giardia around. I took in a sick kitten and went to the vet, but the costs were overwhelming. I couldn't afford to take all three cats to the vet, so I bought this product and carefully calculated the dosage. It was difficult to administer, but in the end, it likely saved the kitten's life and cured the others. While it was a risk to use it off-label, I didn't notice any negative side effects."

"I really appreciate the fast delivery of my ordered products, and my horses absolutely love them!"

"Using this wormer is so simple; my horses never resist, and they seem to enjoy the taste."

"This is such a great dewormer for my horses, and I even used it on my dogs."

"I made a HUGE ERROR with my first order of JEFFERS EQUINE Ivermectin Gel. I mistakenly thought it was paste because the boxes were labeled that way. If I had opened them, I would have realized they contained IVERMECTION GEL. It's easy to use, melts in the mouth, and is 100% EFFECTIVE! I sincerely apologize for my earlier negative review. After receiving my replacement product, I realized my mistake. From now on, I will purchase all my supplies from JEFFERS, they are simply the best!"

"As a horse owner of four (including one mini), I use a lot of ivermectin throughout the year. This product offers a great value and has the same ingredients as more expensive equine wormers. I have been using it for years, and it works!"

"I ordered a six-pack, but initially found only five in the package. After I received a refund for the missing one, I discovered the sixth one while throwing the package away!"

"This horse wormer works wonderfully! My horses are definitely better off. Thanks, Trust Farnan!"

"I personally prefer gel ivermectin, but this white paste is not an issue. The apple taste is a hit with my wild mustang; she takes it willingly!"

"I find this product easy to use and appreciate the lock feature to prevent overdosing. It has a solid reputation as an antiparasitic."

"I rescued a dog with worms in its stool, and after giving Ivermax, the worms were gone in 3 days."

"My horses really enjoy the flavor of this wormer. Although my picky mare won't take it from the tube, I just mix it with sweet feed, and she eats it right away. It's a great product!"

"Interestingly, my horse seems to like the apple flavor less than the non-flavored option, but it's not a significant issue for me."
