Sunshine Biopharma

CA$49.97

More Details
Main highlights
- SWEETENERS: Extreme Mass Gainer is sweetened with Stevia, a natural sweetener very commonly used. To equilibrate the taste, it contains a minute amount of Sucralose (10 mg). All these products are approved by Health Canada and the FDA, and the major scientific studies proved them as safe and armless to human
- PROFESSIONAL UTILITY DESIGN: The Extreme Mass 5lb focuses on physiological output. It delivers the industry's highest calorie-per-serving ratio in a performance-first package, engineered for the serious trainee who demands a functional, high-density substrate to support extreme physical exertion
- INTENSIVE RECOVERY: Highly recommended during "Deload" weeks or immediately following maximal-effort competition. Force-feed nutrients into exhausted muscle tissue to prevent post-strain catabolism and jumpstart the remodeling process
- 60G PROTEIN: Every serving delivers a massive 60g of high-bioavailability protein to activate mTORC1 signaling and ensure structural repair. By pairing a complete amino profile with high-density carbohydrates, this formula directs your caloric surplus toward skeletal muscle hypertrophy rather than adipose storage
- 1582 CALORIES PER SERVING: Stop struggling to hit your caloric surplus. Each massive 375g serving delivers 1,582 nutrient-dense calories, engineered to force your body into a growth state. This is the literal solution for hard gainers and athletes with high-intensity caloric demands who cannot meet their needs through whole food alone
