Mammoth FAQ & Buying Guide
What are Mammoth's most popular products at Fuel Supplements?
Mammoth Pump (both sizes) and Mammoth Mass 15 lb are the consistent best sellers, with the protein bars — especially the boxes of 12 — and Iso-Rush isolate following close behind.
What is Mammoth known for?
Mass gainers and pump pre-workouts. Mammoth Mass is one of the most popular gainers in Canada for hard gainers who struggle to eat enough calories, and Mammoth Pump has a loyal following for training volume and pumps.
Should I buy Mammoth Mass or Iso-Rush?
They solve different problems. Mammoth Mass is calorie-dense — protein plus a large carbohydrate load — for people trying to gain weight. Iso-Rush is a lean whey isolate for anyone who wants protein to support recovery without the extra calories. Pick based on whether your bottleneck is calories or just protein.
Does Fuel Supplements ship Mammoth across Canada?
Yes — we ship Mammoth Canada-wide from our BC warehouses. Orders over $100 ship free, and same-day pickup is available in Port Coquitlam, BC.
