im thinking of buying a protein suppliment to help add some mass.
I tried the search engine, but i got so many hits using words like "protein suppliment"

though i realize this question probobly has been answered before.
Ive remember reading before on another forum about buying the powders that only have protein, and not lots of carbs and protein, because they taste crap and you can just get the two separate for a cheaper price.
Up until now ive been using chocholate milk, 0.5L drinking half during and half after training, this is high in carbs and has decent protein because of the milk. But with the protein powder it will be almost no carbs and only protein, but i should get liquid carbs too right after training and during, am i right?
So should i keep bringing chocholate milk to the gym as a carb drink to drink half before and half after and drink a protein shake in addition?
Any advice would be appritiated. If nessecary, just direct me to the correct posts/articles.
Oh, BTW: im bulking.
