I made up an interesting concoction for after-workout. It contains:
12 ounces of grape juice, two scoops of Whey protein powder (I like chocolate myself) 4-6 ounces of water (to taste) 5 grams of pure powdered creatine monohydrate, and two or three Tblsp of Maltodextrin (to taste)
Sounds strange I know, but it tastes pretty good and as far as I can see, has about everything a growing boy (or girl) needs. When I go to the gym, I'll take my mini cooler and store it in there alongside half a gallon of cold water. That way, I'll have it immediately available. From what I understand, the quicker you get it in, the better off you'll be.
Although, I assume that you being a female, you aren't 210 lbs like me, so maybe a little less on the Protein powder. I dunno.
I don't know if my ratios are correct or not, but I do know that I noticed a major difference a few hours afterwards when I didn't take it. Ouch.
