Dude, Creatine is manufactured in your body naturally and is essential in ATP manufacture, this is just a supplement to boost levels. Just explain that.That stuff sounds nice. Too bad my parents would probably fuss me out over taking it.
Whey protein is well... protein from whey. Whey is the liquid component that's filtered off when you make cheese, natural source!
Casein, I dunno where it comes from actually haha, but it's a protein so honestly I don't see it being so bad. Just try to explain it to them. :D
Also dude just drink Gatorade or something instead of that phony chocolate lol.
