"I am having very good luck with this product and the best part is that my horse does not mind to take it. She has been on this for 1 year and still has no problem with taking it."

"I can tell a difference using Acti Flex 4000, I've used vet suggested glucosamine injections and other formulas that are way more expensive but from now on I'm using this. "

"Used this product on my 23 year old Quarter Horse Mare and it worked wonders. My horse shoer asked me if i gave her bute prior to his visit. I said no I just recently started to use this product (less than 30 days) and he noticed a huge difference in her. Not as stiff and allowed him to lift her legs with out her wanting to put them down. EXCELLENT PRODUCT - she cleans up her entire feed bowl and is now very playful in the pasture - she now has some get up and go"

"I have been using ActiFlex 400 for 10 years... Great product, helped with a slight stifle, gave new " life" to my 29 year old mule, and keeps my 25 year old mule active with ease. Next thing to a " miracle"!"
