Why Dymatize Super Mass Gainer?
- 1,310 calories per serving — a complete caloric surplus in a single shake, purpose-built for mass gain
- 52g protein per serving from a whey + casein blend — fast-digesting whey for immediate recovery, slow-digesting casein for sustained amino acid release
- 10.7g BCAAs including 5.1g leucine — the highest leucine dose of any Dymatize product, supporting maximum muscle protein synthesis
- 252g carbohydrates per serving — dense carb load to replenish glycogen and support the caloric surplus required for muscle growth
- 14 vitamins and minerals — built-in micronutrient support so your mass-gaining diet doesn't create deficiencies
- Banned substance tested — safe for competitive athletes who require clean-label supplementation
- Mixes easily — works with water, milk, or blended into a shake; also suitable for high-calorie baking recipes
Who Is This For?
Super Mass Gainer is designed for hard gainers — people who genuinely struggle to eat enough calories through whole food alone to support muscle growth. If you're in a heavy training phase, playing a sport that demands size and strength, or simply need a reliable way to add 1,000+ calories to your daily intake without cooking multiple extra meals, this is the tool for it.
Take one serving post-workout or between meals. Mixing with whole milk instead of water adds another 150+ calories and extra protein if your caloric needs are exceptionally high.
Who Is This NOT For?
- ✗ Anyone in a cutting or fat-loss phase — 1,310 calories per serving is a bulking tool, not a lean protein supplement
- ✗ Those with average or above-average metabolisms who gain fat easily — excess calories will store as fat if not matched by training volume
- ✗ Beginners who haven't yet optimized diet and training — a mass gainer amplifies a good programme; it won't replace one
- ✗ Anyone with a dairy allergy — contains milk and soy proteins
- ✗ People looking for a low-sugar or low-carb supplement — this is a high-carb, high-calorie product by design
What's In It?
Super Mass Gainer's protein matrix combines fast-digesting whey protein for immediate post-workout amino acid delivery with slow-digesting casein for sustained release over several hours — supporting muscle protein synthesis both acutely and over time. Together they deliver 52g of protein and 10.7g of BCAAs per serving, including 5.1g of leucine, the most research-supported amino acid for triggering muscle growth.
The carbohydrate blend provides the dense caloric surplus that mass gaining requires, while 14 vitamins and minerals ensure the formula supports overall health alongside its primary goal of adding size. Every batch is banned substance tested — the same standard Dymatize applies across its entire performance range.
⚠️ Contains milk and soy. Always read the full label before use. Due to the high calorie content, adjust total daily intake accordingly. These statements have not been evaluated by Health Canada for disease treatment or prevention.
