Usage & Strategic Bulking Protocols
- Basic Mix Guide: Blend or shake 2 heaping scoops (325g) with 20–24 oz. (approx. 600ml–700ml) of cold water, milk, or your favorite beverage in a high-capacity shaker cup or blender until smooth. (Because of the high powder density, using a digital kitchen scale is highly recommended).
- Advanced Smoothie Upgrade: Blend your 2 scoops with a whole banana, a generous tablespoon of peanut butter, and ice cubes to build a nutrient-dense, recovery-focused gourmet meal.
- Extreme Calorie Stack: For those with an extreme metabolism, mix the 2 scoops with 24 oz. of whole milk and two scoops of vanilla ice cream to create an ultra-high-calorie mass-gaining shake.
- Strategic Timing: Use alongside regular whole-food meals—not as a complete replacement—to hit your daily calorie targets. Take daily on both training and rest days.
