• ✗ Not ideal for those seeking mass-gain or caloric surplus — this is a lean protein designed for clean macros, not caloric density

What's In It?

Believe Isolate Protein is built on a blend of Milk Protein Isolate (MPI) and Beef Protein Isolate — two animal-derived protein sources that together deliver a complete amino acid profile to support muscle protein synthesis post-workout. The Milk Protein Isolate contributes a natural casein-to-whey ratio with ultra-low lactose content, while the Beef Protein Isolate (hydrolyzed bovine collagen peptides) adds additional amino acids to the formula. Non-medicinal ingredients are deliberately minimal: xanthan gum (for texture), sucralose (calorie-free sweetener), and natural and artificial flavouring — no proprietary blends and no hidden fillers. The INFORMED Protein certification independently verifies that what is on the label is exactly what is in the tub.

⚠️ Contains milk and beef-derived ingredients. The Chocolate Peanut Butter flavour contains peanut flour. Always read the full product label before use. These statements have not been evaluated by Health Canada or the FDA for the treatment or prevention of any disease.
