i had some of these with 1 rolling stone pill. i have to say, i was very disappointed. i heard really good things about the gel. one thing i did notice, which is typical for me when i am tripping. i was able to put my leg behind my head. i have torn ligaments in one knee and in one ankle. i have never been able to do this before. i also stood on one leg and put the other behind my head. i know it sounds ridiculous, but for me it was mind blowing!!! any comment on this stuff?
