I heard that these contain grapeseed extract and they help with blood pressure, circulation, Nitric oxide, and overall heart health. they also are great for increasing pumps in the gym
I have been taking them now for a week and don't notice any changes. my blood pressure didn't even go down at all and I don't have any difference when I train. do you think this is a gimmick or do you think this stuff just needs more time to work?
