BPI Sports Bulk Muscle XL is an anabolic mass gainer that helps you build lean muscle with more protein, more muscle-building carbohydrates and more “good” calories per serving – so you can get thicker, bigger and stronger.

BPI Sports Mass Gainer is a form of protein powder with higher calorie content than your regular whey protein. Bulk Muscle XL is unique in that it contains the finest protein available, without the excess fats that are in many other weight gainer formulas.

Our high-quality protein powder mixes effortlessly with a blender, shaker or spoon for a smooth, easy-to-drink shake, every time.
