I figure I'll toss my two cents into the jar. If you are only 17, maybe consider holding off with the creatine for now. If you really want to take it though, take it in small doses (5g pre and post workout), and be sure to consume at the very least, 1 gallon of water per day. Creatine is great for enhancing both recovery and endurance. Will it make you faster? No, definitely not....at least not right away. Creatine will allow you to train harder and longer so it could lead to better performance in that regard. Additionally, it will help you last longer in games, so you may be going faster in the third period than normal, but, if doing your normal workout and taking creatine, no, I don't believe it will do anything for you. I would truthfully (like everyone has said) work on eating good, lots of protein/fluids. If you need any help putting together a diet plan, PM me, I have become very interested in the topic and designed somethign for myself (I went from 205 to 170 lifting and eating one way, then got back up to 190 through lifting and eating). I don't play ice hockey anymore, but I do play dek hockey and have noticed a considerable increase in speed since when I began (and weighed 205).
