Are there any heart concerns in taking non-hormone supplements such as NO2 or Creatine for physical training?

Question

I've been working out for the past 4 years and decided to take creatine to aid in building size and strength.

I guess my main concern is the problems that is associated with taking steroids. It increases heart size (because it is a muscle), and have known to cause heart failure amongst other effects.

Now, I do know that Nitric Oxide (NO2) and creatine are not steroids. So my question is, will taking NO2 (such as NO-Xplode) or creatine enlarge the heart? Are there any other concerns I should be worried about? Please list your sources also. Thanks everyone!

I know that NO2 contains caffeine (1 scoop = 8oz drip coffee) and the suggested use calls for 2-3 scoops.

Answer 1

no it won't cause heart failure. weight training in and of itself will cause modest degrees of cardiac hypertrophy but those compounds won't exacerbate things
