Who is Mutant Mass (15 lb bulk) for, and when to take it?
Built for: committed bulkers who use mass gainer daily for 6+ weeks at a time and want the best per-serving cost in the lineup. Same formula as the 5 lb (up to 1,calories vary by flavour — see the nutrition facts panel image above + 56g protein per 4-scoop) — but ~48 servings (2-scoop) or ~24 servings (4-scoop) per 15 lb bag, saving significantly vs buying three 5 lb tubs. When to take: post-workout, between meals, before bed. Best with milk for additional cal + protein density.
How does it taste, and how do you use it?
Heavy, dense, milkshake-style. In stock: Vanilla, Triple Chocolate, Strawberry Banana, Chocolate Fudge Brownie. Mixing tip: blender ball shaker + cold milk for the smoothest texture. Splitting into 2-scoop half-doses through the day is more digestible than 4-scoop in one sitting if you're new to mass gainers. Storage: 15 lb bag — re-seal carefully + store cool/dry to prevent clumping.
What are the macros and bulk-size value?
Per 4-scoop serving: ~1,100 cal, 56g protein, 36g total EAAs/BCAAs/glutamine, advanced carb + lipid blend. Per 2-scoop: 28g protein. ~48 servings (2-scoop) per 15 lb bag. Net Carbs Formula: Net Carbs = Total Carbs − Fibre − Sugar Alcohols − Allulose (where listed) — Mass Gainer is HIGH-carb by design (this is the point).
