Taking creatine, glutamine, aminos and vitamins and lovin it.
i've never taken any supplements or anything, but i do know from my anatomy class that you've got to be really careful with creatine - its a dehydrant ... so it requires you to drink a lot of water ... although it can increase your strength and performance ... your muscles swell with water, so with creatine ... your muscles really aren't as big as they seem - they're just swollen ... which is why a lot of body builders use the stuff ... but just be really careful ... if you don't get enough water in your body for the creatine to dissolve in (and it requires a lot) it can be hard for your kidneys to excrete it ... the unused creatine can even crystallize in your kidney - i know someone who that happened to - and it had to be surgically taken care of ... so the main thing is ... if you're gonna use the stuff - make sure that you drink plenty of water
