Excellent product

A mild colic event and increasing signs of ulcers led us to doing full 28-day ulcer treatment, which means 1 entire syringe per day for 28 days on empty stomach

I am glad you carry the GastroGuard

Thank You For The Speedy Delivery!!! But individually repackaging each one . I would think is a waste of time and supply’s . Bags , stickers and man power. Not including

Thank You For The Speedy Delivery!!! But individually repackaging each one . I would think is a waste of time and supply’s . Bags , stickers and man power. Not including the big box it was sent in . Which would have held it in the original box it was sent in. And protect the gastroguard a little more. Lord knows that it needs all the protection it can get . Gastroguard and ulcerguard is gold . And cost the same might as well go for the Gastroguard .

Works great but its expensive!

I give it 5 stars for how well it works. But 3 stars for price. Outrageous that it costs this much to help our animals feel good.

The product itself is fine; the problem is the packaging. I ordered three boxes (of 7 tubes each) of Gastrogard. Unfortunately, your pharmacy opened the boxes and individually packaged each syringe. What a waste of time, money, and packaging! Additionally, it's much easier for me to store them in the original box (which is instantly identifiable in the barn meds room) than to deal with a big box of individually packaged syringes.
