Quick answers

Is this right for you?

Who is it for?

Prozis Whey Hydro Isolate Clear Black Series is designed for anyone who finds milky shakes heavy, especially in hot weather or straight after training. Clear whey drinks like juice or squash, and because it is made from whey isolate it keeps the high protein and low fat of an isolate.

What can you expect?

A light, juice-style protein drink made from whey isolate that has been acid-treated so it mixes clear instead of milky. It is typically 75-90% protein with very little fat, and fruit flavours rather than dessert ones. Mix it with cold water and let the foam settle for a minute before drinking. With 79g of protein per 100g (around 28g per 35g serving), Prozis Whey Hydro Isolate Clear Black Series sits in a solid mid-range for a clear whey product.

What else do you need to know?

Prozis Whey Hydro Isolate Clear Black Series is a clear whey protein powder made by Prozis. It comes in 700g sizes.
