What is Musclemass?

Musclemass consists of Nutrimuscle native protein for hard gainers. It facilitates the building of muscle mass and strength, stimulating protein anabolism thanks to the mixture of proteins, providing energy to get the maximum out of training thanks to the carbohydrates, and promoting recovery thanks to the protein-carbohydrate synergy.
Nutrimuscle Musclemass is intended to meet your requirements for an immediate muscular effort, especially during a competition or weight training.

What are the benefits of Musclemass?

Muscle mass gain
Muscle growth is optimal when whey and micellar casein (in the form of milk protein) are consumed together. They are available in a convenient mixture thanks to Nutrimuscle Musclemass.
Faster progress
The regular consumption of Nutrimuscle Musclemass is linked to increased power take-off and muscle gain.
Regulated absorption rate
Maltodextrin and dextrose are two forms of easily absorbed carbohydrates. Their rates of assimilation differ because dextrose is digested faster than maltodextrin, which regulates energy intake.
Better tolerance for your digestive system
Nutrimuscle Musclemass is a liquid, so it's more digestible than solid foods. Consuming Musclemass for hard gainers in liquid form is better tolerated by your system than an equivalent consumption of solid food, both in the short and long term.

Nutrimuscle Musclemass

With the arrival of native whey protein which is revolutionizing the world of protein powder, the formulation of Musclemasse Nutrimuscle had to evolve. This is the reason why Nutrimuscle has incorporated native whey protein into the hard gainer. Musclemasse Nutrimuscle represents the first gainer of a new generation: bioactive or native gainers.
Without soy lecithin (GMO) and without aspartame, Musclemasse Nutrimuscle, hard gainer based on native proteins, is flavored with vanilla, chocolate, strawberry and banana.
Complete formula for mass gain, Musclemasse, Nutrimuscle's bioactive hard gainer, contains all the elements to help you gain weight quickly and increase your muscle mass: proteins, carbohydrates (carbohydrates) and vitamins . Musclemasse Nutrimuscle, the hard gainer based on native proteins, brings together the two most effective proteins for the development of your muscles: native whey protein and micellar casein, fast assimilation (to stimulate muscle anabolism) and slow (for a long-lasting anti-catabolic effect).
Musclemasse Nutrimuscle is made up of a duo of complex and simple carbohydrates: maltodextrin and dextrose, a source of rapidly available muscle energy. The reason for this mixing is the existence of a synergy between proteins and carbohydrates, which results in a 20% increase in the anabolic quality of proteins (4).

1 g (gram) = 1000 mg (milligram) - The protein levels indicated in the nutritional composition of Musclemasse Nutrimuscle are intended for 100g or 300g of powder in the packaging, that is to say what you will actually consume. The values on "dry extract" are therefore not displayed as we explain in our page on our transparency.

Usage tips

Who is Nutrimuscle Musclemass for?

Nutrimuscle Musclemass is for:
Athletes, to build muscle mass during the day and also during training sessions.


Dilute 100 g (7 scoops) in 25 cl of milk or room temperature mineral water 3 times a day.
Avoid diluting Nutrimuscle Musclemass in chlorinated water such as tap water, as this would destroy some of the bacteria in GanedenBC30® Bacillus Coagulans.

When should I take Nutrimuscle Musclemass?

Nutrimuscle Musclemass acts very quickly after consumption: the amino acids of thenative whey protein are assimilated in just 15 minutes. The level of amino acids in the blood remains high for 2 hours. Over the next 4 hours, the blood level of amino acids from your native whey protein is halved, while the amino acids of the micellar casein arrive in the bloodstream to continue the anabolic process. Seven hours after consumption, amino acid levels slowly start returning to their initial values. It's now time to enjoy another portion of Nutrimuscle Musclemass or dig into a protein-rich meal.
First thing in the morning
When you get up in the morning, it's important to revive the muscular anabolism that has been cut as a result of a night without food. Simply consume 70-100 grams of Nutrimuscle Musclemass, the hard gainer's powder made from Nutrimuscle native proteins. In fact, you'll need a high dose of protein to fill your empty stomach first thing in the morning, because at this time your digestive system takes a lot of the protein from that first meal. Upping your intake ensures that your muscles also receive all the protein they need. (1) This anabolically disastrous situation explains why simply eating protein in the morning almost triples the magnitude of anabolism (2).
Between meals
It's very important to take 50 to 100 grams of Nutrimuscle Musclemass, the Nutrimuscle hard gainer native protein, between main meals so that you don't go more than two hours without eating.
In the evening
In order to continue muscular development at night, take 50 to 100 grams of Nutrimuscle Musclemass (native protein for hard gainers) just before bed and replace nocturnal catabolism with powerful anabolism.
Before a training session
Nutrimuscle Musclemass is an excellent pre-workout supplement. Consume 70 grams of Nutrimuscle Musclemass one hour before a training session to boost endurance.
During a training session
Nutrimuscle Musclemass is a native protein for hard gainers and also an exercise drink. Take a sip of Nutrimuscle Musclemass every 10 to 15 minutes to fight against catabolism and fatigue.
After a training session
Taking 100 to 150 grams of Nutrimuscle Musclemass supports recovery by stimulating not only protein anabolism, but also by accelerating the resynthesis of muscle glycogen.

How do I take Nutrimuscle Musclemass?

How do I prepare and consume my proteins?
Gas generated by the consumption of protein powder do not come from the protein itself. It mainly comes from the temperature of the liquid in which it is diluted. Cold liquid, which is often too cold, consumed several times a day in high quantities (1.5 to 2 litres) creates a thermal shock in the digestive system, causing bloating, gas, or even a case of the runs if you're very sensitive.
Nutrimuscle recommends consuming its protein products in a room-temperature liquid: prepare your protein in the morning in a bottle and then consume throughout the day. You have a smooth, even mixture, because the bubbles have evaporated. So, say goodbye to burps! What's more, the ambient temperature of the contents will not disturb your digestion, so gas is also a thing of the past.

Mixing with other Nutrimuscle products

Synergies between supplements
Nutrimuscle Musclemass improves the assimilation of biotics, carnitine, and creatine.
Adverse reactions between supplements
To avoid bloating, Nutrimuscle Musclemass is not to be taken in conjunction with potassium bicarbonate.
