Quick answers

Is this right for you?

Who is it for?

MuscleTech Iso Whey 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 72.7g of protein per 100g (around 33g per 46g serving), MuscleTech Iso Whey sits in a solid mid-range for a whey isolate product.
