Trec Hard Mass is a bulk protein-carbohydrate supplement enriched with vitamins, L-glutamine, and HMB. The product helps to effectively replenish your daily energy and protein demand; the supplement can be also used as a meal replacement.
Hard Protein Blend provides protein derived from three sources: whey protein concentrate, egg protein, and calcium caseinate, differing from each other by absorption kinetics. These sources are characterized by good bioavailability and – thanks to the balanced release time – a part of amino acids enters the bloodstream already after an hour, whereas the second part is released within up to 6 hours. This allows the maintenance of a continuous supply of building components to skeletal muscles.
Massive Carb Matrix – a source of carbohydrates, which are the main energy substrate of skeletal muscles and enable the creation of energy reserves in the form of muscle glycogen. The ingredients of this mix are maltodextrin, starch, and fructose. Absorption kinetics allow for quick blood saturation with glucose and its gradual release, which prolongs the effect of satiety. Easily available energy contained in the form of carbohydrates effectively increases the calorie content of the nutrient, thus supporting the development of muscle mass.
Muscle-Pro Formula – provides L-glutamine peptides, which play an important role in the process of nitrogen transport in the body, supporting post-exercise regeneration and the maintenance of the nitrogen balance. The content of CaHMB, i.e. calcium beta-hydroxy-beta-methyl butyrate, protects muscle tissue and prevents muscle catabolism.
Addition of vitamins
The supplement has been enriched with a vitamin complex containing vitamin C, vitamin E, vitamin B1, B2, B6 and B12, niacin, pantothenic acid, folic acid, and biotin. They participate, among others, in the conversion of nutrients into energy, muscle protein synthesis or muscle glycogen synthesis. Their addition makes the supplement a suitable wholesome meal replacement.
To sum up, Trec Hard Mass is a rich protein-carbohydrate complex that facilitates muscle mass building and daily protein replenishment. It will be ideally suited as a post-workout meal, which will provide nutrients necessary for regeneration in an easy and accessible way.
The number and size of daily portions will stem from protein deficits and energy needs in individual diets. It is worth using in the morning on an empty stomach, during longest breaks between meals and before and after training. Using immediately after physical effort will cause regeneration of depleted glycogen supplies and provide fast-absorbing protein. Using with milk with high fat content will additionally increase its energy value and the amount of protein and make the supplement portion a balanced meal substitute.
Trec Nutrition is a company offering a wide choice of products for athletes. Products of this brand include carbohydrate-protein supplements, protein and energizers. The offer also includes amino acid supplements, creatine, HMB, fat burners, thermogenics, products supporting metabolism and speeding up the regeneration of joints.

The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents energy., determining the value of metabolic energy contained in 1 g of the component. Most commonly used is the equivalent of Atwater: protein 4 kcal/g for carbohydrates 4kcal/g, and for fat 9kcal/g.
Proteins (proteins, polypeptides) is a polymer, of which the basic units (monomers) are amino acids. Protein is composed of carbon, oxygen, nitrogen, hydrogen and sulfur, and is an elementary nutrient necessary for the proper functioning of the body, an ingredient and a component of tissues, part of the hormones and enzymes and other bioactive substances. Protein determines the proper metabolism and energy processes, as well as all other life processes. The sources of natural proteins are foods of animal origin (including meat, fish, eggs, dairy products) and plant origin (legumes, soy). Deficiency of protein leads to protein malnutrition and a significant weakening of the body. It can lead to anaemia, reduced immunity, muscle relaxation, disorders of the digestive system. Also, overdose protein is undesirable because it can lead to acidification of the body, and interfere with the digestive system and an increase in the concentration of homocysteine in the blood. It is a component of many supplements and nutrients necessary for the proper functioning of the body, both showing a low physical activity, or training the strength and endurance competitions.
Dosage: strength athletes: approx. 1.7 - 2.5 g / 1 kg of body weight; endurance athletes and strength -endurance athletes approx. 1.3 - 2 g / 1 kg of body weight, people with low activity approx. 0.8 - 1.1 g / 1 kg of body weight / 24h. In estimating the amount of protein, you should take into account the intake of other nutrients (carbohydrates and fats)
Carbohydrates are an essential nutrient. They are divided into: simple sugars (monosaccharides), disaccharides and polysaccharides. In terms of the human bioavailability of carbohydrates is divided into: digestabe, those which are digested in the gastrointestinal tract by transferring energy to the tissues or cells (such as starch, fructose) and indigestable, resistant to digestive enzymes (e.g. cellulose) . Affects blood glucose levels (glycemic index) and the metabolism of insulin (insulin index). The greatest demand for carbohydrates occurs before physical activity or in the middle of it, because they increase the exercise capacity, consumed after exercise provide regeneration. In the sports diet the absorption rate it is important of carbohydrates and reactions of the organism. Available in mono-preparation supplements and part of the energetic supplements, creatine stacks, nitrogen boosters.
Dosage: according to the statistics of the Institute of Food and Nutrition, carbohydrates should comprise about 50% of daily energy intake. In some diets, used residual carbohydrate consumption, not exceeding 30g / 24h.
Fat is an essential nutrient plant and animal organisms. Because of the nutritional value and composition of fats are divided into: saturated (mono-saturated and multi-saturated fatty acids) and unsaturated fatty acids (including essential fatty acids - EFA). The group of lipids include lipids (triacylglycerols, waxes), complex fats (glycolipids, phospholipids), sterols and isoprenoids. Saturated fatty acids is a group of fatty acids having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is bound by a single bond. May adversely affect the lipid profile, so they can be used in limited quantities. Fats are a concentrated source of energy, with different flavours, facilitating the consumption and swallowing of food. They have building functions (part of cell membranes and co-create the white matter of the brain). EFAs are precursors of tissue hormones and biologically active compounds. The unsaturated fatty acids include fatty acids from the group Omega-3, Omega-6 and Omega-9 (the last digit indicates, on which, counting of the end of the chain, there is a double bond in the appropriate carbon chain. The essential fatty acids include: acids, medium-Omega-3 [n-3 ] included in EFAs [essential fatty acids], and long chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) Omega-6 and Omega-9. the number indicates that the last double bond in the carbon chain is on the third from the end carbon atom. The acids from the omega 3 group are essential components of cell membranes, they are precursors of eicosanoids and biological activators. They must be combined with ingestion in suitable proportions of Omega-6 acids.
Dosage: Depending on demand and applied diet. It is generally accepted that fats should constitute 20-30% of the energy (calorie) of meals daily.
Vitamin C (ascorbic acid) it is a vitamin soluble in body fluids, can be taken from foods (fruits and vegetables), or as drug derived synthetically. The largest of its resources can be found in broccoli, Brussels sprout, kale, black currant fruit and hawthorn, citrus fruits, tomatoes, Savoy cabbage, potatoes. In fact, intake of vitamin C of the food products does not limit the absorbed quantity. Vitamin C (ascorbic acid) is a potent antioxidant, it is an antitoxic, increasing the immune system due to the elimination of risk of bacterial contamination. Vitamin C prevents rupture of blood vessels, affects the blood cholesterol level. It substantially increases the absorption of iron. Inhibits the growth of cancer cells. Lowers stress levels.
Vitamin C deficiency causes abnormal development of connective tissue, cracking capillaries, abnormal calcification of bone tissue, impaired absorption of iron, scorbutus. With the lack of vitamin C, all kinds of injuries do not heal up properly. Vitamin C deficiency can be caused by smoking; each cigarette is destroying up to 100 mg of vitamin C.
Dosage: The demand is 60-80 mg daily. It does not limit the ability to consume higher doses. Some side effects may occur only with longer taking of synthetic vitamin C.
Ascorbic acid – vitamin C. Its biologically active form is the L-isomer, which negatively rotates the polarised light, so that it is a dextroisomer (laevorotatory vitamin C does not exist). It is a strong antioxidant; it reduces the amounts of free radicals, which reduces oxidative stress, a factor leading to cell apoptosis, which is why it is indicated to be a cause for premature ageing.
It supports the immune system functions and increases body system immunity. It is an essential element of the collagen synthesis path, which is why it positively affects the condition of connective tissue. Hence, it promotes also wound healing and increases the durability of capillary vessel. It is involved in transformations of tyrosine and carnitine as well as of some nutrients, so that it affects metabolism. It can also have an impact on the nervous system functions, as it reduces mental fatigue.
Higher supply of vitamin C is especially recommended in the periods of more intensive body system burden, after infections and in order to accelerate regeneration. The indications for increased supply of the vitamin are also hard physical work or intensive trainings.
Vitamin E (tocopherol) is a fat soluble. Due to its antioxidant action, it is a protection of other vitamins (e.g. Vitamins A). Protects the body against free radicals, strengthens the walls of blood vessels and its capacity, causing their dilation and dissolution of blood clots. With the reduction of coagulation, it is used as an antiatherogenic medicine, it allows for the proper course of pregnancy. In cooperation with selenium it slows the ageing process of cells, strengthening connective tissue. In the food it is present in whole-grain bread, sprout and grains, vegetable oils (soybean, sunflower), soya beans and sunflower seeds, vegetable fat and hen egg yolks. Also it is used in sports medicine in the form of nutrients and supplements.
Vitamin E deficiency reduces building of red blood cells, results in changes in muscle and disorders of pregnancies.
Dosage: for children, 0.5 mg / 1 kg of weight; for adults 10-30 mg per day.
Calcium (element chem. symbol Ca, atomic no. 20, the group of alkaline earth metals) is the basic building substance of bones and teeth, in which stored is 99% of the element, in the form of hydroxylapatite. When building bones and teeth, phosphorus is very important in the right proportion. It is a base-forming element and activator of many enzymes (ATPase) necessary to release the energy of ATP. It has a significant effect on blood clotting and regulates blood pressure and neuromuscular conductivity. Thanks to the reduced permeability of cell membranes, it soothes the symptoms of food allergies. Calcium is actively involved in the metabolism of iron interacts with vitamins A, C and D and phosphorus, magnesium. Natural source of calcium are animal products (dairy products, sardines, salmon, sprats eaten with bones) and plant products (nuts, soybeans, sunflower seeds). Absorption takes place in the small intestine (less in the colon), it has an effect on the level of lactose, insoluble fibre, organic acids, alkalinity (low pH). The best absorption have organic compounds (lactates, amino acid chelates etc.). Obstructing the absorption of calcium is caused by: phytic acid and oxalic acid as well as excess fat. Scientific studies have confirmed that the combination of calcium, magnesium, boron and vitamin D in dose 3 mg / 24h effectively prevent osteoporosis. Supplements on the market are both mono-preparation supplements (enriched with vitamin D3) and multi-component supplements, available at www.muscle-zone.pl.
Calcium deficiency disorders manifested in the construction of the bones (osteoporosis) and iron metabolism. The symptoms are: rickets, cramps and muscle tremor, osteoporosis.
Excess resulting from an overdose of calcium supplements containing vitamin D3 for children and adults overdose of calcium (hypercalcemia). Symptoms of hypercalcemia are: lack of appetite, vomiting and constipation.
The dosage administered in various publications are inconsistent: 800 - 1000 mg / 24 h (100 - 500 mg / 24h)
Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine) is soluble in the liquid. It participates in the metabolism of proteins, fats and carbohydrates. By reducing the amount of fat in the blood do not enable deposition of the body. It helps the absorption of magnesium and vitamin B12 (cobalamin). It works on the muscle antispasmodic and anti-inflammatory pain in the joints. It acts anti. It provides efficient operation of the brain. It increases energy increasing vigor of a man. The demand for vitamin B6 increases during pregnancy and breast-feeding infants. The natural product is: yeast, eggs, wheat germ, meat (liver), wheat bran, nuts, peanuts peanuts, soybeans. There is a hypothesis that can be synthesized by intestinal bacteria.
Deficiency of vitamin B6 causes abnormal metabolism of proteins, decrease in lymphocytes in the blood, causes a feeling of lethargy and fatigue intensifies.
Dosage: 1.5-2.5 mg daily (increased demand during pregnancy and lactation).
What is pyridoxine hydrochloride?
Pyridoxine hydrochloride is a basic, the most commonly used form of vitamin B6 in supplements and fortified foods. It is a vitamin soluble in water. It converts to the active form of the vitamin - pyridoxal phosphate.
Vitamin B6 is a cofactor in many enzymatic reactions. It takes part in the production of many neurotransmitters, such as GABA, serotonin and catecholamines and it takes part in the metabolism of amino acids, carbohydrates and lipids. It is an important factor for the process of the creation of red cells and hemoglobin and its deficit may be one of the factors causing anemia. This vitamin contributes to maintaining proper energy metabolism and is important for maintaining well-being and good psychological condition. Its presence supports the breakdown of pro-inflammatory homocysteine to cysteine and further metabolites, thanks to which it may decrease the risk of atherosclerosis and cardiological incidents.
Pyridoxine hydrochloride may be found in many vitamin B complexes and vitamin-mineral preparations available in the offer of muscle-zone.pl.
Vitamin B2 (riboflavin) is soluble in liquids, is involved in the metabolism of proteins, fats and carbohydrates. Required for growth of the organism. Takes part in the production of erythrocytes (red blood cells). It is located in natural foods, such as yeast, meat (especially liver, kidney, heart), milk, fish and green leafy vegetables.
A deficiency of vitamin B2 inhibits the growth, diseases of the mouth, loss and greasy hair, seborrhea and stratification of nails. Increases skin roughness and susceptibility to acne and oily skin.
Dosage: 1-2 mg per day.
Folic acid - also known as vitamin B9, is a synthetic form of naturally occurring folates. It needs to be transformed to folates in order to be biologically active also in the human organism. Therefore, its supplementation is recommended to people who do not have problems with methylation processes.
The majority of people associate folic acid with the period of pregnancy. It is definitely a justified association. Proper supply of vitamin B9 conditions correct development of the fetus and prevents disorders of neural tube defects in a baby.
Supplementation with folic acid also demonstrates positive influence on the functions of the nervous system of adults. Some sources say that it is conducive to maintaining beneficial emotional states. Moreover, folic acid takes part in the process of erythropoiesis, thanks to which it enables efficient production of red cells.
Supplementation with folic acid should be also considered by men who deal with low sperm quality. It was proven that complementing the level of vitamin B9 is conducive to increasing reproductive abilities of men.
Biotin (vitamin H, co-enzyme R) is in a group of B vitamins, due to the presence of sulphur compounds it is involved in the synthesis of ascorbic acid (vitamin C). Also synthesized in the intestines. It enhances the production of hormones and regulates cholesterol levels. It reduces muscle pain. It prevents hair loss and graying of hair. It soothes the skin inflammations. No toxic effects. Often combined with other B group vitamins and vitamin A. The natural sources of biotin are: whole grain bread, yeast, eggs (yolk), milk, brown rice and cheese.
Daily demand: 100-300 mg per day
What is cyanocobalamin?
Cyanocobalamin is a basic, the most commonly met form of vitamin B12 in vitamin B complexes and multivitamins available on the market.
Vitamin B12 is the most known for its influence on neurology. It takes part in building and regenerating myelin sheaths of neurons, thanks to which it contributes to the protection of the nervous system against damages. Because of the ability to increase the level of S-Adenosyl methionine, vitamin B12 may contribute to more efficient synthesis of many neurotransmitters, thanks to which it positively influences well-being and psychical condition.
This vitamin is also engaged in the process of blood production and its deficiencies contribute to the creation of megaloblastic anemia. Its deficits may also concern vegetarians and vegans, elderly people, people with absorption disorders and those using drugs neutralizing gastric acid.
Cyanocobalamin is included in the composition of many complex vitamin supplements that may be found in the offer of muscle-zone.pl.
Whey proteins (proteins from micro-filtration of cow's milk) are approx. 20% of milk protein. They are characterized by a biologically active ingredients, particularly exogenous amino acids (BCAA and lysine and EAA), also beta-lactoglobulin (36%), alpha-lactalbumin (20%), immunoglobulin (10%). They store retinol and iron in cells, stimulate the level of the bacterial flora. The use of whey protein supplements is recommended in almost all sports, mainly representatives of power sports and bodybuilders as a dietary supplement of high quality protein, especially pre- and post-workout. Available in the form of pure concentrates, hydrolysates and isolates as well as a component of nutrients (protein bars, carbohydrate-protein meal type MRP).
Dosage: according to individual needs, typically 30-90 grams per day.
Maltodextrin - complex carbohydrates derived from starch by enzymatic depolymerization, having a long and high bioavailability (bioavailability comparable to glucose). They are divided into low-sugered, medium-sugered and high-sugered, wherein each of the has a high glycemic index (GI) - more than 80 to approx. 110. These are an easily digestible source of energy, supporting the insulin metabolism, supplementing muscle glycogen and that improving creatine and amino acid transport into cells muscle, influencing the increase in exercise capacity. In the sports supplementation preparations containing maltodextrin are used pre- and post-workout and as a complement to the energy value of food.
Dosage: the lack of standards unit consumption. The supplements conventionally used 20-70g / 1 doze, about three times a day of training. Not recommended to take preparation before going to sleep, and for use by people with a tendency to weight gaining.
Starch is a plant sugar store, composed of particles of glucose produced in the process of photosynthesis (α-D-glucoses linked by α-1,4-glucosidic bonds), and is equivalent to the animal glycogen; belonging to the groups of basic carbohydrates. It consists of amylose and amylopectin. It is insoluble in water, after soaking swells making better filling of the gastrointestinal tract and reduces hunger. During the heating the gelatinization starch takes place. Starches can be divided into: native (achieved e.g. potato, corn, wheat) and wax (e.g. In the waxy maize). Native starch used in the starch production (stiffening agent) and puddings and jellies. The waxy starch amylopectin prevails. Starch is an essential nutrient in the carbohydrate diet of different nutrients and supplements, available at the www.muscle-zone.pl
L-glutamine - amino acid building endogenous proteins, glutamic acid amide. In the human body it is responsible for the synthesis of proteins, acid-base balance and removing ammonia outside of the organism. With the shortage of energy taken from the muscle tissue, glutamine with alanine participate in the process of gluconeogenesis, and participate in the production of glucose substrate. L-glutamine has a direct impact on the proper functioning of the digestive system and immunity of the organism. Participates in the synthesis of one of the most powerful antioxidant - glutathione. It has anti-catabolic potential. It is found naturally in foods of animal and vegetable origin and high protein supplements. Used as mono-preparation or multi-component amino-acid supplements and supplements enhancing biological recovery after exercises, often in combination with BCAA.
Dosage: 5-20 g per day (portioned during the day, and after training and waking up). The minimum dose used in supplementation is 2-15g per 1 serving.
Ca-HMB is in liquid form and is a combination of calcium and beta-hydroxy-beta-methyl butyrate in a single molecule, resulting in a neutralized acidic. Benefits of calcium are discussed under the entry: calcium. HMB is a derivative of leucine synthesized within the body. Its source may be also plant foods (grapefruit, alfalfa (lucerne)) and some fish species. The substance has a low anti-catabolic and anabolic potential, helpful for people starting an increased physical activity, it may also contribute to the reduction of body fat. It is a component of anti-catabolic supplements, creatine stacks and amino acid as well as mono-preparation supplements.
Dosage: should not exceed 6 grams per day.
HMB - beta-hydroxy-beta-methyl acid, a fat derivative of leucine (endogenous amino acid) synthesized from leucine in the human body. In its natural form (unfortunately in small quantities) is available in grapefruit, alfalfa and meat of some fish. Information about special anabolic and anti-catabolic action appears to be greatly exaggerated. However, it is recommended to use HMB by untrained persons who take an physical activity, in order to ensure adaptation to exercise and protect muscle tissue during exercise exceeding the general standard. In the sports supplementation is used rarely (due to not fully confirmed action in reducing the body fat, anabolic and anti-catabolic properties).
Dosage: 3-5 g per day
