It was free with a purchase, I passed it on to someone else at the stables

My horse won’t eat this powder. If I add it to his AT+ and Visceral he won’t eat those either so everything gets wasted.

I swear my arthritic 19-year-old QH gelding is doing so much better since he’s getting Mad Barn MSM. I rarely see a limp in him anymore!

love it the packaging and the product

Love this MSM !!! All my horses are doing amazing on it

I've purchased your MSM several times, the last two bags I received had a very strong, unpleasant smell.

Have been giving MSM to my horses, dogs, and I have taken it myself. It has been very effective for all of us. Thank you for this product. However, your shipping charge of $15 is more than half of the price of the product, and that is really frustrating. So I might order more often if shipping was more reasonable

Love this powder, only complaint is I wish the enclosed scoop was a full dose for a 1000lb horse. Having to scoop out three times takes much longer when trying to efficiently feed multiple horse or preportion supplements ahead of time for barn workers.

Mad barn has been great to deal with so far. The msm was a much better deal than my usual supplier.

High quality and can't beat this price!
