First of all, its NO (nitric oxide) not no2, and it has been proven to be quite effective. Most NO products simply contain argenine which is what increases production of the NO and actually has potential to increase HGH. It's been shown that it opens up blood vessels and allows more nutrients, oxygen, and hormones to be transferred to them.
Just wondering but do you actually take supplements or do you run off of what you read?(no offense)
There's really no reason to take anywhere near 20grams of creatine unless your loading, and even then its a bit excessive.
Are you kidding? It's recommended to at least,AT LEAST get 5 grams pre workout and 5 priot.
There's a lot of creatine products out there that claim to work better than mono (CEE, Kre-Alkalyn) but we can't say whats going to work best for his body. Start with bulk mono, its cheaper and works fine, and see how that effects you before you go buying expensive brands that might not work any better.
Good point!
