after using a whole bottle of this.. i can easily say that my elbows when i do skull crushers, the intense pain i got is gone! and im about 3 weeks off of any joint pills and the pain still isnt there!! Also, ive delt with INTENSE shoulder pains after just 3 sets into any shoulder workout. and that pain ive delt with for about 7 months? GONE! this product will work wonders. consider it!
