I started taking a cellucore pre workout call c4 original. Its was bought from walmart. After only using it for three days my heart has been fluctuating and beating in a rythym that I find similar to anxiety attack or when overcome by a significant amount of stress. Its not painful just bothering and worriesome. I've discontinued the use of this product and if things do not go back to normal in a few days I'm going to seek medical attention. My questions are has anyone used this product. Has anyone had this happen with pre workouts and is it something that needs to be looked at immediately or if things should return back to normal as long I stay away from stimulants for awhile. And I find it very important to emphasize that I am exaggerating nothing about this post. Any input is very appreciated
Thank you.
