Recommended Intake

Add 1 scoops (30g) to 150-200ml of water. Shake and consume immediately. Use less liquid for a thicker and stronger tasting shake. Adjust to taste.

We recommend 2-5 servings daily to increase your protein intake. Best taken at breakfast, post workout and in between meals.

Experts suggest a minimum 1g of protein per pound of body weight daily to promote lean muscle growth. Others mention 1.2-1.7g of protein per kg bodyweight. (e.g. 70kg – 70x1.7 = 119g of protein per day)
