pre workout tingles make it worth it for me. really the only thing I can "feel"
mentally ready after 20 minutes and my face starts itching and skin gets some redness. Kind of like a niacin flush, but a little different. does not fade as fast as niacin. hell one day for niacin very intense, next day nothing. evryone with high bp knows how this goes
I vote for yes it is worth it. pretty cheap. what the hell right, thrown so much other shit in the pile what is one more
