Quick answers

Is this right for you?

Who is it for?

Prozis Whey Hydro Isolate Black Series 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 78g of protein per 100g (around 24g per 31g serving), Prozis Whey Hydro Isolate Black Series sits in a solid mid-range for a whey isolate product.

What else do you need to know?

Prozis Whey Hydro Isolate Black Series is a whey isolate protein powder made by Prozis. It comes in 700g 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. All links to Amazon and retailer sites are affiliate links - this is how WheyWise stays free.
