i use prolab, creatine monohydrate powder. you can buy it from vitacost.com.
I take 1 scoop (approx 5 grams) every night before i go to bed. I scoop it up, stick it in my mouth, take a drink of water and swish it around for a second, then swallow it. easy, fast, and does the job.
I don't pee all night because of it like greg does.
and creatine really helps me. as greg says, some respond, some don't. I think it is fabulous.
if you have a hard time remembering, as I use to, stick the creatine next to the other supplements you take at night. so when you grab your glutamine, steroids, or fish oil, or eye cream, or whatever, then the creatine is right there and you wont forget. just a thought.
