International Protein Extreme Mass Dangerously Anabolic Weight Gainer was formulated as a powerful mass-building supplement.  The nutrient rich formulation, including 5 types of protein, a unique selection of complex carbohydrates and a healthy blend of Canola and Sunflower oils with fast-burning MCT Oils, puts the emphasis on ensuring the body maintains a highly anabolic state to maximise extreme mass and size gains.

One of the key attributes that sets Extreme Mass apart from other Mass Gainers on the market is that it is a genuine energy rich high calorie weight gainer, not just a high carbohydrate formulation being passed off as a mass gainer.  To facilitate lean mass gain the body needs extra calories.  While adding carbs (carbohydrates) provides a muscle sparing energy source, they still only provide the same energy as protein.  Gram for gram, a true weight gainer, like Extreme Mass, provides a higher concentration of energy than protein and carbs to make it easier to consume the calories required for optimum lean weight gain. Extreme Mass uses fast burning MCT Oils to provide rapid high density energy.  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).

Another "Dangerously Anabolic" feature of Extreme Mass is its superior natural amino acid profile, providing all the necessary protein factors essential for muscle growth.  Hydrolysed Whey Protein Isolate (Whey Peptides), High Glycomacropeptide Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC), Calcium Caseinate and Egg Albumen were carefully selected not only for their specific amino acid profiles, but for their unique absorption rates.  This is the same proven proprietary blend of 5 proteins found in International Protein's PROTEIN SYNERGY 5. As a result Extreme Mass also delivers a constant supply of essential amino acids into the bloodstream for a period of hours, ensuring a high positive nitrogen balance is maintained for maximal muscle growth. Quality multi-phase release proteins are even especially critical to hard gainers so why settle for a cheap WPC (Whey Protein Concentrate) based weight gainer?

Complimenting the anabolic proteins in Extreme Mass is a balanced combination of muscle sparing carbohydrates from Medium Length Glucose Polymers and easily digested low-allergy Rice Starch.  These multi-phase release carbohydrates provide both immediate and long term energy to help satisfy fast metabolisms, fuel high intensity training, improve anabolic recovery and spare protein to drive massive muscle growth whilst minimising fat gain.

Who should use International Protein Extreme Mass?

Men & women over the age of 15 who have difficulty consuming the required amount of energy (calories) to enable them to gain lean mass or maintain their bodyweight while undertaking high intensity resistance training or high levels of sport and other activities. Target athletes include, but are not limited to bodybuilders, power-lifters, rugby players, boxers and open-rules fighters and track and field athletes.

  • What Makes Extreme Mass Different from Other Mass Gainers?

    Extreme Mass stands out as a genuinely energy-rich high-calorie weight gainer, providing a higher concentration of energy than protein and carbs alone. It includes a unique blend of proteins, complex carbohydrates, and a mix of Canola and Sunflower oils with fast-burning MCT Oils to support lean mass gains.

  • How Does Extreme Mass Facilitate Lean Mass Gain?

    Extreme Mass offers a balanced combination of proteins and muscle-sparing carbohydrates to provide the extra calories needed for optimum lean weight gain. The inclusion of fast-burning MCT Oils and a blend of Canola and Sunflower oils ensures rapid high-density energy without the fatty acids associated with heart disease.

  • What Makes the Amino Acid Profile in Extreme Mass Superior?

    Extreme Mass boasts a superior natural amino acid profile derived from carefully selected proteins like Whey Peptides, Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC), Calcium Caseinate, and Egg Albumen. These proteins not only offer specific amino acid profiles but also have unique absorption rates, providing a continuous supply of essential amino acids for maximal muscle growth.

  • Who Benefits Most from Using International Protein Extreme Mass?

    Extreme Mass is ideal for men and women over the age of 15 who struggle to consume the necessary calories for gaining lean mass. It's especially suitable for those engaged in high-intensity resistance training, competitive sports, and other physically demanding activities like bodybuilders, power-lifters, athletes in combat sports, and track and field athletes.

  • Does Extreme Mass Contain Harmful Fats?

    Extreme Mass includes fast-burning MCT Oils, which are high in saturated fat but do not contain the fatty acids associated with heart disease. Additionally, the saturated fat content is balanced by a blend of Canola and Sunflower oils, rich in heart-healthy Monounsaturated and Polyunsaturated oils.

  • How Does Extreme Mass Support Anabolic Recovery?

    The combination of multi-phase release carbohydrates from Medium Length Glucose Polymers and low-allergy Rice Starch provides both immediate and long-term energy. This helps fuel high-intensity training, enhance anabolic recovery, spare protein for muscle growth, and minimize fat gain.

Been mixing with milk after each workout and find it really helps with recovery, and I'm gaining.

In a shaker it mixes beautifully.

Ordered the vanilla based on the other reviews an I'm not disappointed.

Thanks International Protein & Mr Supplement.

By far the most delicious mass gainer I've had and I've tried Serious Mass, True Mass and Real Mass among others so I've had a lot. The powder mixes well and really easily even with stirring and it's got some really good ingredients. It actually makes me want to drink my shake, which is probably why my gains have been pretty consistent this time round

A good balance of Carbs & MCT oils great for building quick muscle for injured athletes as i tore my mcl ligament in my knee, good source of nutrition for the joints and muscle to help speed up recovery.

I rate all the International Protein range and really like the Extreme Mass, because it tastes so damn good, mixes well and is low in sugar- I don't want crappy carbs when I'm trying to bulk!

After using cheaper brand supplements that really didn't give the results I was after I was told by a friend at a local gym to check out Mr Supplements.com.au for some good value and quick delivery of protein powders etc. I wanted a good value low sugar protein supplement and something to gain lean muscle mass which is something I find hard with such a fast metabolism. So I purchased a 4kg tub of international proteins extreme mass, the taste was awesome!! the chocolate truffle goes down a treat and best of all I was so stoked to see a few kilos of lean muscle mass added to my lean frame, Id recommend this as good lean muscle gainer for sure. Best of all this is an Aussie product so I'm all for it!!
