Does any one have any success with a supp that increases your cardio capacity? I have a max vo2 test as a requirement to be accepted into Fire accademy and am having sinus surgery in a few days,so I will be down for a while. I need to get my cardio up in a short amount of time after surgery test is comming up fast. I have read cordyceps and tried it but have a mold allergy and reacted to it. Arginine or nitric oxide boosters? Any thoughts?
