Well it turns out I finally went back to GNC, returned what they gave me, got a full cash refund and purchased GNC Pro Performance Creatine Monohydrate.
It's my first time using creatine so I have a few questions for you frequent users.

First, when do I take creatine?
How much grams a day do I take creatine first starting?


Additonal information:
16 y/o male
142 lbs.
15% BF (estimated with online calc)
currently trying to cut to show abs and still maintain good muscle mass.

Thanks for all your help!
