Extreme Mass Key Features

Suitable For All People

Extreme Mass has 6 types of high quality proteins, energy giving carbs and healthy fats combined to provide a nutrient packed high calorie shake that meets the needs of everyone from fast growing teens to busy mums, active tradies, serious sportspeople, fussy eaters and the elderly.

Flexible Nutrition

Use a full serve with low fat milk for nearly 700 power packed calories or a half serve on water for around 220 macro balanced calories to meet your own specific needs.

Timed Release Protein & Carbs

By utilising proteins from Whey Peptides, WPI, WPC, Egg Albumen, Micellar Casein & Calcium Caseinate, Extreme Mass provides a timed release of protein and carbs as these ingredients start to break down within minutes and continue for up to 8 hours. Carbs from long chain glucose polymers and easily digestible rise starch provide both short and long-term energy.

Digestive Enzymes

International Protein have added Digezyme® to help break down proteins into simple amino acid chains to facilitate the absorption of these amino acids within the body.

Grass Fed WPI

Whey protein isolate is made from healthy, happy grass fed cows, with naturally occurring nutrients including CLA, beta-carotene and Vitamin D. So you can be happy knowing your Amino Charged WPI is full of quality protein.

Easy Digesting

Extreme Mass is made from easily digested proteins and carbs, the light milkshake consistency won’t bloat so it’s easy to consume extra calories, especially for people with small appetites.

Suggested Use

Mix 100g (3 scoops) with 500ml of reduced fat link or soy milk in a shaker or blender. Take 2-3 times daily IN ADDITION to your regular meals for weight gain. Best times for use are mid morning, mid afternoon and before sleep or whenever extra calories are required.
