Great Product

Posted by 5178034329878009525 on Nov 22, 2013

I have been using it for the last year; I honestly can say that it helped me a lot. I tried in the past several prescription medications bit always suffered from side effects. Nothing of the sort with DLPA.

Jury still out

Posted by Reviewer2268240 on Feb 23, 2011

I bought this product for my dog. It was recommended by a fellow dog person to help with the hind end weakness in aging dogs. I cant tell yet if its working but if it does the same thing for my dog that it did for hers, I am very hopeful.
