Quick answers
Is this right for you?
Who is it for?
MaxiNutrition Promax Lean Protein Powder is designed for athletes, lean-bulk dieters, and anyone who wants maximum protein with minimal fat and carbs. Whey isolate is also a better option for people with mild lactose sensitivity, since the extra filtration removes most of the lactose.
What can you expect?
A lean, fast-absorbing protein with very low fat and carbohydrate content. Whey isolate goes through extra filtration to deliver 85-95% protein purity, which means more protein per scoop and fewer calories from filler. Expect quick absorption, making it ideal straight after a workout. With 81g of protein per 100g (around 28g per 35g serving), MaxiNutrition Promax Lean Protein Powder sits at the higher end for a whey isolate product.
What else do you need to know?
MaxiNutrition Promax Lean Protein Powder is a whey isolate protein powder made by MaxiNutrition. It comes in 980g sizes. Every price on WheyWise is read from the retailer’s own page and re-checked daily and sorted by cost per 100g, so you can see both the cheapest option and how current it is.
