its not the protein doin that to you.....might be the milk (if u use it) to mix it with....unless you're using a weight gainer that has tons of dextrose
It is probably something else in your diet, not the powder. Unles your ingesting hundreds of grams of protein from it in one sitting, it shouldnt be adding fat to your gut,
I agree, it's not the protein. But, with winter coming on as long as you are gaining, this would be an excellant time to do a bulker. Start cutting in early spring to reveal new muscle mass.
