Heart/Chest pains, Nitric Oxide?
Hey guys, I've been panning through this website's forums and a lot of the members seem like they're trustworthy and willing to help, so with that being said I could use some help. I'm 16 years old and I have been taking NO Black Powder, (950% More Nitric Oxide), and at only 1 & 1/2 scoop after and even during my workout I noticed a terrible pain in the tissue around my heart, and it seems pretty serious. I went down to just 1 scoop, and same thing. 3/4 scoop, not so much, but still a lingering pain. I'm down to just 1/2 scoop, and it is so low I don't even feel the effects, yet am still feeling some pain. I am PRETTY sure it is the NO that is causing my heart to work harder, and not the caffeine/other stims. I'd still like a helpful opinion though, my friends have told me to get a pre workout without a lot of NO in it, so I was thinking about getting 1mr. Thanks guys! :)
