Who is Mammoth Mass (5 lbs) for?
Mammoth Mass is Canada's original lean weight gainer since 1987 — for hard-gainers, post-cut bulk phases, athletes needing 1000+ extra clean calories per day, and underweight lifters trying to put on size. Each serving delivers ~1,250 calories, 60 g protein (whey concentrate + isolate + milk protein), 39 g amino matrix (BCAAs + EAAs + glutamine), clean carb blend (oats, sweet potato, quinoa), and MCT oils. Pairs well with Mammoth Pump pre-workout, PVL Pure Creatine (if you want extra creatine beyond Mass's 5 g), Mammoth EAA9 for fasted training. **Important**: Mammoth Mass is NOT a regular protein shake — it is intentional bulking macros (~1,250 calories per 4-scoop serving). Do not use if you're cutting or maintaining weight. Skip if you're calorie-restricted, vegan, or have a severe milk allergy.
How and when should I use it?
Mix 1 serving (4 scoops / 320 g) with 500–700 ml of milk or water. Many users split into 2 shakes per day (2 scoops each) to avoid appetite suppression. Best times: post-workout, between meals, or before bed as a high-cal mass meal. Storage: keep tightly sealed in cool dry pantry.
What are the macros?
Per full serving — 4 scoops (320 g): 1,250 calories, 60 g protein, 230 g carbohydrate, 10 g fat (4 g saturated), 9 g sugar and 145 mg sodium, plus Mammoth's amino matrix (~39 g BCAAs, EAAs and glutamine). Scoop size is about 80 g. Per single scoop that's roughly 313 cal, 15 g protein, 58 g carbs, 2.5 g fat and ~2 g sugar. See the full per-scoop table in the product description to scale to any amount.
Allergens, gluten-free, vegan, certifications?
Contains milk (whey concentrate + isolate + milk protein). Contains oats — verify gluten-free claim on current label image (oats are commonly cross-contaminated unless certified GF). Not vegan. Made in Canada, third-party tested, formulated by licensed Naturopathic Doctor + IOC-trained sport nutrition professionals. 30-day default returns apply (yes, even on opened supplements ≤7 servings used). Onward upgrade adds 90-day coverage plus 5% cash back, about 4% premium at checkout.
Why should I buy from Top Nutrition & Fitness?
We're a Montreal-based supplement and snack shop that's been serving Canada since 2016 — over 10 years. Our owner personally taste-tests and hand-picks everything we carry, so you only get products we genuinely stand behind at honest value. We're an authorized retailer (real, fresh, properly stored stock — never grey-market), we pack every order carefully so it arrives in great shape, and Canada-wide shipping is fast. Friendly, product-savvy support is one message away, and every order is backed by our Onward 90-day guarantee.
How many scoops should I take, and how do I split a serving?
A full serving is 4 scoops (320 g) = about 1,250 calories and 60 g protein, but most people don't take it all at once. Split it through the day — for example 2 scoops post-workout and 2 scoops between meals (or as a mini meal replacement, or whenever you want extra calories). About 2 scoops is usually what gets you around 30 g protein, so a single scoop is rarely how a gainer is used. This 5 lb tub holds about 28 scoops (~7 full servings), so at 2 scoops per shake you get roughly 14 shakes. Want fewer carbs? Mix 1 scoop of Mammoth Mass with a scoop of regular whey to keep the calories and flavour while bumping protein and cutting the carb load.
What are the macros per scoop?
Mammoth Mass lists its label per full serving of 4 scoops (320 g): 1,250 cal, 60 g protein, 230 g carbs, 10 g fat, 9 g sugar. Divided per scoop that's roughly: 1 scoop ~313 cal / 15 g protein / 58 g carbs; 2 scoops ~625 cal / 30 g protein / 115 g carbs; 2.5 scoops ~781 cal / 38 g protein / 144 g carbs; 3 scoops ~938 cal / 45 g protein / 173 g carbs; 4 scoops (full) = 1,250 cal / 60 g protein / 230 g carbs. The product description has the complete per-scoop table including fat and sugar.
