You have got questions about the product

  • Branched side chain amino acids in optimal proportions 2:1:1
  • High quality of the product - good solubility and perfect taste
  • Stimulates the growth of muscle tissue
  • Decreases the feeling of fatigue
  • Limits muscle catabolism
  • Increases energy level

Trec BCAA High Speed is the highest-quality source of branched chain amino acids. It is characterized by perfect absorption and wonderful, refreshing taste.

BCAA - branched chain amino acids, amino acids with branched side aliphatic chain, which constitute an incredibly important group of amino acids for the proper functioning of the organism, in the composition of which there are leucine, isoleucine and valine. An optimal quantity proportion was applied in the preparation - 2:1:1. They are an important factor for muscle development, they also play other important functions in the organism. Their amount in food products and supplements which are the source of protein is often pointed as the main indicator of their quality.

Promotion muscle anabolism
The most common reason for which branched chain amino acids are supplemented is the support of the processes of muscle tissue growth. It is mainly related to the ability of leucine to activate pro-anabolic mTOR pathway. This phenomenon is so important that it has its own name - leucine threshold. It is related to the minimal amount of leucine in a meal, which is responsible for its ability to activate anabolism.

Limiting catabolism
The amount of dry muscle mass in the organism is also influenced by the activity of BCAA on MAFbx and MuRF-1 proteins. They are responsible for the promotion of atrophy, i.e. the breakdown of muscle fibers in the organism. It was proven that supplementation with branched chain amino acids may limit their activity, preventing muscle catabolism. It is especially important in the period of weight loss, when limited calorie supply may be related to the insufficient amount of protein, essential to maintain musculature on the high level.

Limited feeling of fatigue
Apart from pro-anabolic function of BCAA, their ability to limit the feeling of fatigue is also important. It is related to the influence of branched chain amino acids on the transport of tryptophan in the organism. Both BCAA and tryptophan use the same transporters. Thanks to this, supplementation with branched chain amino acids may limit the ability to transport tryptophan to the brain. It limits the production of a substance, for which tryptophan is a precursor, i.e. serotonin, responsible for the feeling of fatigue.

Backup energy source
Branched chain amino acids in extreme conditions may be used to produce energy. By taking part in the pathway of gluconeogenesis, glucose may be produced from them, which is the basic energy source for the organism. Thanks to this, BCAA supplementation may additionally positively influence physical efficiency during long-lasting, intensive training sessions.

To sum up, BCAA High Speed is a universal supplement in the accessible form of powder, which after mixing with water forms a refreshing drink, ideal to consume around training time. Its application should be of interest to all people, who want to increase the pace of muscle anabolism or protect themselves from catabolism, as well as of those who are looking for a supplement, which increases training possibilities by limiting the feeling of fatigue.

BCAA are three essential amino acids having a side branched aliphatic chain (isoleucine, leucine, and valine) and a similar course of metabolic processes, occurring in the muscle tissue. In its natural form, they are found in high-protein animal foods (i.e. beef, milk proteins). BCAA have the anti-catabolic and anabolic potential. They support energy carriers during the energy crisis and affect the functioning of the nervous system (eliminate stress, reduce fatigue), hormone activity and kinases, which are responsible for the metabolism of proteins. In the sports supplementation they are used as supporting elements of exercise capacity (strength and endurance) and post-workout recovery; also as anti-catabolic and catalyst of anabolic changes. Taking BCAA after exercise almost immediately restores the levels of these amino acids in the blood (excluding liver) and supplies the muscle tissue. Leucine activates of mTOR kinases (starting anabolism of muscle proteins) and has the intensified effect with insulin, which acts on the PI3-kinase and protein kinase B. Branched amino acids chain BCAA, willingly used by strength, strength-endurance and endurance athletes, they are available in the form of single-component supplements, and advanced amino acid supplements, creatine, pre- and post- training stacks, and isotonic drinks.
Dosage: usually 1-2 grams of BCAA per 10 kg of body weight per day. Mainly before and after training.




Leucine is an essential amino acid, one of the three branched chain amino acids, ketogenic, its isomer is isoleucine. It affects the secretion of anabolic hormones (insulin, combined carbohydrates), acts on enzymes (mTOR) starting the process of muscle protein synthesis and controlling its course. Protein synthesis by leucine is affecting the development of bones, muscles and skin. It reduces the fat tissue. Without the availability of leucine, protein synthesis is impossible. It naturally occurs in animal products (such as eggs, meat, dairy and fish), plant origin, and as a post-training supplements, BCAA, EAA, no-boosters, creatine stacks, carbohydrate supplements. Ir is also in the form of mono-preparation supplements. It is one of the most important amino acids for the athlete's body, basically in every sports discipline.
Dosage: The demand is 5-10 g / 24h, dosage pre- and post-workout and in the morning after waking up.




Valine – is a branched essential amino acid, indispensible for the functioning of the nervous system (receiving of sensory information), involved in muscle protein synthesis and energy generation. Administration of additional doses of valine before exercise (or immediately after) has anti-catabolic effect, protecting the proteins and allowing them to rebuild. It is slightly stimulatory (delays symptoms of fatigue during workout), affecting the level and relations of neurotransmitters. It helps to protect the liver. It stimulates an increase in strength and muscle mass, participates in the reduction of body fat. BCAA, EAA, and other mixtures of amino acid supplementation, protein and protein supplements and carbohydrate-stacks, brings positive results in strength and endurance sports.
Valine deficiency can occur in case of increased energy needs of the body,
as the result of stress and too much stress load.




Isoleucine is an essential branched amino acid (BCAA), leucine-isomer. It has anti-catabolic action ( protects muscle against decay), glucogenic (an alternative energy source when the level of glucose after exercise decreases, helps for the regulation of blood glucose levels, reduces the deficiency of fatty acids), anti-catabolic (muscle protects against decay), reduces stress. It participates in the synthesis of proteins (including the synthesis of hemoglobin). It is an essential part of the regeneration of damaged tissues of the body, and after intense training. It occurs in products containing animal protein (meat and dairy products, eggs, dairy products) and plant (almonds, walnuts) and dietary supplements.
Isoleucine is applied with other branched chain amino acids: leucine, valine, and in the supplement complex type of BCAA, in the proportions: leucine: isoleucine: valine = 2: 1: 1. The supplements used in competitive sports requiring increased strength, the bigger share of isoleucine is used.
Dosage: No standard daily use. Frequently applied directly after the workout during the decrease of the glucose level of or at fatty acid deficiency.
