Smart Mass Gainer

Most mass gainers are just sugar and maltodextrin in a bag. Smart Mass is different — a lean mass gainer built around real macros, slow-digesting carbs, and the same premium whey + casein protein blend that makes Select Protein famous.

Designed for athletes who want to add lean mass without the dirty bulk. 225 calories per serving, balanced across protein, carbs, and fat — clean enough to double as a meal replacement, effective enough to fuel serious muscle growth.

• ✔ 25g protein — whey + casein blend for fast and slow digestion, sustained amino acid delivery
• ✔ 25g slow-digesting carbs — including a slow-digesting sugar for steady energy, not a spike and crash
• ✔ 5g clean fats — balanced macros, not empty calories
• ✔ 225 calories per serving — ideal as a post-workout shake or convenient meal replacement
• ✔ Maltodextrin free — no cheap fillers, no dirty bulk
• ✔ PEScience flavor quality — the taste and texture you expect from Select, in a mass gainer

Available in Gourmet Chocolate and Gourmet Vanilla. 14 servings per bag.

Bulk the right way. Lean gains, not dirty weight.
