Highly recommend the ArcEquine! A few months ago my 19 year old showjumper was really stiff and some days looked quite lame behind, I was thinking I would have to retire him. I had ordered him a joint supplement to try but I’m happy to say it’s not even been opened! I started using the Arc unit and the difference is like night and day. He’s not stiff anymore, he’s playing every day in the field again and been back out jumping even stepping back up a height class, the first time he’s jumped that height since 2016! I’ve now started using it on my younger horse also after seeing the amazing difference! Thank you ArcEquine!
