Excellent First Impressions
After a couple of weeks, I feel these have had a beneficial effect on my athletic performance- running and cycling harder and stronger, with better recovery.
Also, my painfully aging knees, which have been severely restricting training, and made me wonder how long I can continue with competitive running, have been far less painful, and I have been able to return to running regularly.
Not a scientific response, but just my experience so far with this product..
