The Benefits of Maximuscle Promax Lean Protein Powder

Maximuscle Promax Lean has been scientifically created with the specific focus on weight and muscle support to enable you to reach #yourMAX.

Promax Lean powder contains a high-quality blend of whey protein isolate (55%) and calcium caseinate (41%) which combine to influence the taste and texture whilst delivering 28-30g of protein per serving (depending on the flavour).

Our blended Promax Lean powder is a fat free, sugar free, high protein shake designed to support lean muscle development.

Our Maximuscle Guarantee

Available in four delicious flavours - Chocolate, Vanilla, Strawberry, Banoffee. Promax Lean is free from artificial colours, artificial flavours and unnecessary thickeners for a cleaner taste and better consistency. It is gluten free, soy free and suitable for vegetarians. Plus, the Maximuscle 100% guarantee is our assurance that we use only natural colours and flavours to give you a delicious protein shake that is both smooth and satisfying.

The entire Maximuscle range is screened for banned substances and accredited on the Informed-Sport programme. Perfect support for a new to protein consumer or a seasoned sports professional.

Maximuscle Cyclone comes in the iconic 980g black tub which is 100% recyclable. This blend of protein powder is easily mixed.

Remember, buying in larger quantities gives much better value with our 'Buy More, Pay Less' guarantee. We stand by our money back guarantee, if you are less than satisfied with any of our products.
