So my roommate and I have been lifting for the past year or so and he recently purchased NO2. If you have not heard of NO2, it is a muscle supplement that provides more oxygen to the muscles. NO2 also contains crealtine (water bonds to the muscle making the muscle look bigger). Once he started taking the supplement he has gone up in weights exponentially and to be quite honest I am thinking of purchasing the supplement. Now there are a few questions I have. First: What are you opinions on using supplements? Secondly: Are supplements such as NO2, protein, or crealtine illegal in the Navy? (I was recently Pro Rec'd and I don't want to do anything to jeopardize my commission) Thirdly: Will taking this help on my running time or will it hurt it? (if it will hurt my run time theres no way in hell I want to use it) Thanks .
