Rated 5 out of 5 by this product is wonderful i really like this product i love how it makes my horse feel as i run barrels on her and it really does work!! she runs and turns so much better while using rapid flex!! May 9, 2010
Rated 5 out of 5 by Wonderful results I saw a friend use this for their horse that was in his mid 20's and would lay around and not want to get up. Within a week the horse was up and running around. I use it on a 20yr old and 17 yr old with great results. They act as if they are 10yrs younger. You can see they their joints and body motion feel so much better. (This does not hypp up a horse if you are asking.) March 20, 2010
Rated 5 out of 5 by Very good! i adopted a 24 year old arabian gelding with very bad arthrithis.. he would not eat the medication what the vet gave us, so i bought rapid-flex wich worked from the first week!and my horse has no problem with the taste. November 10, 2009
Rated 5 out of 5 by miracle product rapid flex is wonderful. i had a horse with severe arthritis. she could barely walk when i got her. my vet wanted to put her down she was so bad. after 2 weeks, she was up walking. after a month she was doing even better. 3 months my vet came back and couldnt believe she was up walking and even trotting to her feed bowl. he now recommends rapid flex to all his clients. this is a great product and i tell ever one to use it.
