Trying it out based on others' reviews

Posted by Reviewer2635763 on Nov 08, 2015

I tried it out based on other people's reviews. Don't see much effect but then again I don't know what effect to be looking out for. If it improves blood circulation, it's good enough for me. :) Update: I've noticed an obvious change in my ability to sweat after taking this. During exercise i sweat faster and much more than if I didn't take this supplement.
