Ive been kind of wondering about this because i just caught the cold/flu/whatever else it is and what i have been wondering is if tylenol or aspiring can have an effect on your workout? It thins your blood right? Ive been taking NO2 and wondered if the tylenol could counteract it or anything. Because NO2 makes more blood flow yet the aspirin thins it out. Would anything happen when taking both is the question im trying to get at here?
