"Have used this product for the last couple of months for rota-tor cuff / bicep tendentious from tennis. Went to two orthopedic Dr + active movements for 2 months with not much success. This product is the only product that has worked for me. I'm not sure I understand the bio-science that it does, but what i can say that it works and does make a difference. Highly recommend this product."
