Supposedly Krealkalyn is THE creatine. I've read regular Creatine Monohydrate works, but it's like taking a Civic when you can take, say a Ferrari. The Civic will take you there, but the Enzo will get you there FASTER. Plus you'll look better using it.
The only supplement I've ever tried was Whey and it *worked*, but I'm hearing a lot more S&C people online make Creatine (Especially Krealkalyn) their supplement of choice. Once I get my goal weight of 180 naturally I'll probably try getting my hands on them too. Good luck, Grinder.
