International Protein Extreme Mass - Weight Gainer Protein!

International Protein are an Australian sports nutrition company known for their range of high quality protein powders, mass gainers and muscle building products. Reviewed today at Genesis, we take a look at Extreme Mass!

What is International Protein Extreme Mass?

Extreme Mass by Internaitonal Protein - now stocked at Genesis Nutrition - is a market-leading mass gainer packed to the ceiling with high quality proteins, carbohydrates and fats. Utilising five sources of protein, Extreme Mass is able to assist the body in maintaining anabolism during muscular recovery and repair. Including a healthy blend of canola and sunflower oils with fast acting MCT oils, this product is your ticket to maximising extreme mass and size. 

How does Extreme Mass Work?

Each 100g serving of Exreme Mass contains 429 calories, 42.5g of protein, 42.5g of carbohydrates and 9.4g of fat. Many users prefer to take two scoops, granting over 800 calories for a greater mass effect. Gram for gram, a true weight gainer like Extreme Mass provides a higher concentration of energy-over-protein-over-carbs, which makes it easier to consume calories needed for lean weight gain. While MCT Oils are high in saturated fat, they don’t contain the fatty acids that cause heart disease. Just the same, the saturated fat content is balanced by a blend of Canola and Sunflower oils, high in Monounsaturated and Polyunsaturated oils, including Essential Fatty Acids (EFA’s) Linoleic (omega 6) and Linolenic (omega 3).

Our Thoughts:

At Genesis, we've tried our fair share of weight gainer products, and all too often you'll get a formula packed with fillers and sub-par ingredients. Extreme Mass by International Protein is a fantastic bulking protein which combines the best of whey with the best of carbohydrates and fast burning fats.
