If you haven't been training for at least six months, probably more like a year... There's no reason you should even know what creatine is. Whatever you do don't stop taking protein though. Just look into postworkout nutrition on google, lot's of solid info. Make sure you are taking simple carbs after a workout and not just protein, as it needs to be delivered to your cells via insulin, which requires simple sugars. Get some dextrose and maltodextrin and drink that right after your done weight training. Then 20 minutes later have a protein shake.
