Since using Proanthenols, I have recovered from a shoulder overuse injury. I wasn’t expecting to notice something go away completely! My shoulder had been so weak that I couldn’t raise more than 5 pounds overhead and was using a band instead of any weight. After about 4 weeks, I noticed that I could lift a dumbbell, and then I got into the shoulder press machine to check it out and could raise the weight! The lowest weight on the machine, mind you, but the motion had been impossible for many months prior to this. And now, after just 2 months on them, I am completely pain free and have my full range of motion back. So, as a Massage Therapist and an active person who runs, bikes and swims weekly, I can say I will stay on them now! I have been recommending them to anyone who complains of pain in their muscles and joints as well.
