Most "mass gainers" are 1,200-calorie sugar bombs you can't actually drink twice a day. BULK is the lean-mass alternative — 500 calories, 35g whey-based protein, 80g complex carbs, only 7g sugar per 4-scoop serving — designed to add quality calories on top of real meals without wrecking your gut or your blood sugar.
Built on maltodextrin and whey protein concentrate with cocoa, MCT oil, and a creamer base for smooth mixing. One serving in 24–36 oz of water or milk; split into halves if a full shake is too much in one sitting. Available in Massive Chocolate Milkshake and Massive Vanilla Milkshake.
- ✓500 calories per serving — engineered to add calories on top of real meals, not replace them
- ✓35g protein from whey concentrate — supports normal muscle protein synthesis and recovery
- ✓80g carbs with only 7g sugar — fast-absorbing maltodextrin to refill glycogen without a sugar crash
- ✓MCT oil + dutch cocoa — smooth mixing, milkshake texture, no chalky aftertaste

Is this right for you?
- ✓You're a hardgainer or in an intentional muscle-gain phase and struggle to hit calories from food alone
- ✓You want quality calories — real protein and complex carbs, not a sugar shake
- ✓You train hard and need a post-workout option with both protein and glycogen-refilling carbs
- ✓You'd rather sip half-servings through the day than slam a 1,200-cal shake at once
- ✗You're cutting or in a calorie deficit — 500 cals per serving will work against fat-loss goals
- ✗You're lactose intolerant or sensitive to dairy (contains whey concentrate + milk + soy lecithin)
- ✗You're on a low-carb or keto plan — 80g carbs per serving doesn't fit the macro profile
- ✗You'd rather hit calories from food — BULK is a tool, not a replacement for eating
How to use it
Full serving: Mix 4 scoops into 24–36 oz of water, milk, or your beverage of choice. Shake or blend until smooth. Best timed post-workout or between meals when you need extra calories.
Half serving: If a full shake is too much in one sitting, split it — 2 scoops post-workout, 2 scoops mid-afternoon. Same total fuel, easier on digestion.

Frequently asked questions
Is this a meal replacement or a protein powder?
Neither. BULK is a calorie-dense gainer designed to add 500 cals on top of meals you're already eating. If you want a balanced meal replacement, look at NOURISH. If you want clean protein only, see Whey Isolate.
When's the best time to take BULK?
Post-workout is the highest-leverage window — your muscles are primed to refill glycogen and use the protein. Otherwise, between meals when you can't physically eat more food. Half-serving twice a day works better than one full slam if your stomach can't handle 36 oz at once.
Can I stack BULK with other MaxWell supplements?
Yes. The standard mass-gain stack: BULK post-workout, Creatine Monohydrate daily for strength output, and NOURISH as a meal swap when you can't sit down to eat.
Does BULK have lactose, soy, or gluten?
BULK contains milk and soy (whey protein concentrate + soy lecithin in the creamer base). Not gluten-free certified. If you're lactose intolerant, whey concentrate carries more lactose than isolate — try Whey Isolate instead.
