Description

Why choose Nutrimuscle's BCAA Constructors?

Nutrimuscle has chosen to produce high-quality BCAAs at a competitive price, while notably avoiding amino acids from human hair, pig hair, or transgenic soy fermentation (GMO).

Nutrimuscle BCAA 4.1.1 Constructors products have not undergone any ionising radiation treatments and are guaranteed by the 2 leading producers on the market: Fufeng and Shine Star.

  • The amino acid L-Leucine is obtained from hydrolysed, filtered, and centrifuged goose feathers from geese farmed for the food industry. 
  • L-Isoleucine and L-Valine are made from bacteria produced by the fermentation of a mixture of guaranteed-GMO-free corn syrup and dextrose.

What are BCAA Constructors ?

BCAAs (branched chain amino acids: Leucine, Isoleucine, and Valine) belong to the essential amino acids family. The human body does not have the necessary enzymes to produce them, and only your diet and/or supplementation can provide the BCAAs needed to keep you healthy and support your muscles.

Nutrimuscle BCAA 4.1.1 Constructors stimulates muscle development through maximum leucine supplementation and the anabolic support of isoleucine and valine.

What are the advantages of BCAA Constructors ?

Bulking

Nutrimuscle BCAA 4.1.1 Constructors' role is threefold. It stimulates protein synthesis, decreases the rate of cell damage and boosts the production of stem cells, which will increase the number of fibres in your muscles.

Better recovery

Nutrimuscle BCAA 4.1.1 Constructors compensates for these losses while enhancing muscle protein synthesis, and thus recovery after a training session.

Usage tips

Who is Nutrimuscle BCAA Constructors for?

Nutrimuscle BCAA 4.1.1 Constructors is for:

  • Athletes looking to improve their performance, muscle building, and recovery during and after a workout.
  • Athletes who wish to boost their protein intake with amino acids in order to improve their anabolic response.

Dosage

Take 5 g (10 scoops / 12 capsules) before + during your training session.

When should I take Nutrimuscle's BCAA Constructors ?

Athletes can take 5 g of BCAA orally to increase BCAA levels in the blood in under 15 minutes. The peak increase occurs 60 minutes after consumption, after which point levels will begin to decrease. This maximum increase is delayed by 50% when BCAAs are used during a workout (6). This delay helps us understand why it is necessary to start taking BCAAs ahead of a workout rather than only during the session.
Before a training session

Take 5 g of Nutrimuscle BCAA 4.1.1 Constructors 30 minutes before exercising in order to fight muscle catabolism.

During a training session

Strengthen each litre of (maltodextrin and/or dextrose) carbohydrate drink with 10g of Nutrimuscle BCAA 4.1.1 Constructors. The mixture should be used at regular intervals throughout your workout.

After a training session

Scientific research shows that topping up whey protein with BCAAs just after a workout increases your anabolic response by 60% while slowing catabolism by 24% compared to whey alone.

Between meals

Take 2 to 5 g of Nutrimuscle BCAA 4.1.1 Constructors in addition to protein supplements between meals and at night.

How do I consume Nutrimuscle BCAA Constructors?

Nutrimuscle BCAA Constructors can be diluted in your water bottle at room temperature or as a protein booster in your shaker.

Interactions with other Nutrimuscle products

Synergies between supplements:

5 g of Nutrimuscle BCAA 4.1.1 Constructors can double the leucine increase obtained with 30 to 40 grams of whey protein or from casein. The anabolic efficiency of these proteins is increased thanks to this boost.

Nutrimuscle BCAA 4.1.1 Constructors improves the assimilation of L-Leucine, Carnitine, and Creatine.

Antagonisms between supplements :

Nutrimuscle BCAA 4.1.1 Constructors should be used with caution in conjunction with Potassium bicarbonate.

High-quality BCAA 4.1.1

As with our BCAA 2.1.2 RESISTANCE, the quality of the raw materials we consume daily is paramount.  

At Nutrimuscle, none of our products are chemically or genetically modified.

Our leucine is not derived from human hair, pig hair, or transgenic soy fermentation (GMOs). It is obtained from hydrolysed, filtered, centrifuged goose feathers that have not been treated with ionising radiation. The feathers come from geese intended for use in the food industry.

Isoleucine and Valine are made from bacteria resulting from the fermentation of a mixture of guaranteed non-transgenic corn syrup and dextrose. 

This quality is essential for amino acids such as Nutrimuscle BCAA 4.1.1 Constructors, which are consumed every day or even several times a day and in large quantities.

Benefits of Nutrimuscle BCAA Constructors in more detail

Muscle development

Nutrimuscle BCAA 4.1.1 Constructors' role is threefold. It stimulates protein synthesis, decreases the rate of cell damage, and boosts the production of stem cells, which will increase the number of fibres in your muscles (hyperplasia).

BCAAs during training sessions

When it comes to strength training, BCAAs are destroyed during the energy cycle. BCAA levels decrease by approximately 20% during intense training.

This depletion explains:
- Interrupted muscle anabolism during exercise.
- Skyrocketing catabolism.
Without supplementation, this decline continues in the hours that follow, further reducing your post-workout anabolic response. Nutrimuscle BCAA 4.1.1 Constructors compensates for these losses while enhancing muscle protein synthesis, and thus recovery after a training session.

Muscle recovery

5 g of BCAA before squat training reduces muscle soreness and speeds up recovery (2).

The amino acid L-Leucine is obtained from hydrolysed, filtered, and centrifuged goose feathers. The feathers come from birds intended for use in the food industry. Therefore, it is not derived from human hair, pig hair, or transgenic soy fermentation (GMOs), and it has not been treated with ionising radiation.
No chemical or genetic modifications

The raw materials used for the manufacture of L-Isoleucine and L-Valine are bacteria derived from the fermentation of a mixture of guaranteed non-transgenic corn syrup and dextrose. What matters most to us is the quality of the raw materials, your health, and the results you achieve using our nutritional supplements.

These qualities are essential for amino acids such as Nutrimuscle BCAA 4.1.1 Constructors, which are intended for frequent consumption (every day or even several times a day) in large quantities.
