Bulk the right way with Select Smart Mass, the lean mass gainer. 

With clean fats, 25g slow-digesting carbs including a slow-digesting sugar, and 25g protein from whey and casein for fast + slow digestion, we've formulated Smart Mass to be geared for lean mass gains, rather than dirty weight gain from simple sugars and fats.

Looking for a convenient meal replacement? 1 packet of Smart Mass gives a healthy, balanced 225 calorie drink with 25g protein, 25g slow-digesting carbs, and 5g fat.

Smart Mass delivers our unmatched amazing flavor and texture that you won't find in any other weight gainer. Maltodextrin free!
