BEST QUALITY AND PRICE - Saturday, February 27, 2021Been buying this msm from PC Network for years and has always been the best quality and best price on the market. I use this product on my rescue ranch on all my horses, dogs and on myself for joint and arthritis. I have horses and dogs that are so stiff until I put them on msm. This product does not cure but it makes all our lives a whole lot more comfortable. This is a great company and the best prices with the most pure form of msm. I have bought many other products from them and always very pleased. THANKS PC NETWORK!
