Yes side effects: Read huffington post article about high school athletes requiring surgery for compartment syndrome. Look at ingredients of C4 extreme, if you do not understand the ingredients then avoid them. Make sure your parents aware of this supplement and ask if any family members have high blood pressure or sudden death. Please avoid taking this supplement.
