that's the stuff my wife recommends for all her patients. People, dogs, horses and the occasional politician.
She's a physical therapist.

We get it at costco for about $50 on sale.

Hey Fritz, if you don't mind asking your wife something, could you ask her if the pills she recommends are better than this? http://www.amazon.com/Wellesse-Movement-...B001G7QQ5O I buy this stuff at Costco on sale but would switch to a pill if it was better. Thank you.
