After having taken the CIRC-02 for two months,just one per day, I noticed that some dark blue knobbly veins on the inside of my legs, adjacent to and slightly above my knees, had totally disappeared from my left leg, and were barely visible on the right leg. This improvement could only be attributable to the CIRC-02, because I had not been taking any other treatment. These areas of dark blue knobbly veins each covered an area of several square inches and had been noticeable for several years.This is obvious improvement, but I cannot help speculating as to what other benefits may be improving my vascular system? Yes, I will keep taking the CIRC-02.
