My horse is a little reactive to different situations. My friend/trainer recommended Max Calm. Though it's only been a short time since I started using it, I believe my horse is a little less worried and slightly more placid. Early days, but I think this product is helpful and have already suggested it to my friends.

My mare has always been very hot and sensitive. I tried her on the max calm and it seems to have settled her nerves. She’s able to focus much easier as soon as I get on, and feels softer and more relaxed through her whole body. She’s still hot and sensitive but the energy is usable now. I’ve been really impressed with the product so far.

Haven’t noticed much difference with max calm in my 10 yr old thoroughbred mare with 2 pumps so a bit disappointing. My biggest complaints are box arrived and one of the jugs lid was off and had leaked all over the box and other two jugs, your pumps suck, they leak from the spout and from the base where attached to the jug, always a mess to clean up
