Thank you for the recommendation. I found at their website an interesting list of ingredients...

Thank you.....and thanks for the correction in my spelling!!
I have used Australian Dream (works pretty good and is guaranteed), and have used Blue Emu (not impressed).
But following the directions on the Penetrex (a bit pricey, but does work good), I did find relief; along with taking Bromelain and Rutin for inflammation (which causes pain).
