I am getting good results with my clients using the butter cups. I have used them with clients with IT band, quadriceps, or hamstring issues. They cover large areas better than multiple smaller cups, and clients like how they feel.
I purchased the butter cups from Mark Carangelo, who directs the American Institute of Alternative Medicine in East Brunswick, New Jersey.
