PROSUPPS Dr. Jekyll Nitro-X is a pre-workout consisting of 3 active systems supporting the exercise capacity of the body. The scope of these systems include the activities that increase strength and endurance (beta alanine, creatine hydrochloride), energy and focus (choline bitartrate, anhydrous caffeine, theacrine [TeaCrine®]) as well as the muscle pump (glyceryl monostearate, L-citrulline aspartate, arginine silicate [Nitrosigine®], l-norvaline). The preparation has been enriched with niacin and calcium.
Strength and endurance
Both of these exercise parameters are very important for successful training or systematic sports progress. The greater the strength, the greater the load that can be lifted during a repetition/series /session. Lifting heavier weights allows for an easier training adaptation, and thus facilitates making progress. Greater muscle strength makes it easier to do more repetitions before muscle failure. More reps using more weight is a quick way to succeed.
Creatine is the most effective and most-thoroughly tested substance permitted to increase muscle strength and mass. This important component of muscle cells increases the body's potential in the scope of ATP production and generation of more energy necessary to perform anaerobic physical activities. The more advanced form of creatine is creatine hydrochloride, characterized by better stability and solubility as well as greater concentration, which lessens water retention and improves saturation of muscle cells.
As a result of intense muscle work, lactic acid is formed. It destabilizes the transmission of nerve impulses and muscle contraction. Beta-alanine is converted to carnosine, which in turn inhibits the decrease of pH in muscle cells which is associated with the accumulation of lactic acid. Consequently, the muscles can work longer and more efficiently. Beta-alanine enables increasing muscle endurance by allowing for doing additional repetitions in a series of a given exercise.
Power and concentration
The growth of energy increases body’s ability to perform some work, and the focus during this work allows for achieving a better effect. This rule also applies when supporting physical exercise. This advanced pre-workout preparation contains substances that increase both energy and concentration.
Choline bitartrate helps to increase the amount of choline that is part of the lipids that form cell membranes and is required for the proper functioning of the muscle and nervous system. Both caffeine and theacrine are stimulants that increase the ability of the body to perform work, and their supplementation before a physical exertion causes an improvement in exercise parameters during a workout. The preparation uses an anhydrous form of caffeine, which is distinguished by a better bioavailability, resulting in a stronger effect on the body.
The phenomenon of the muscle pump not only gives a great visual effect, which motivates users of pre-workout supplements to perform harder work, but also provides many benefits invisible to the naked eye. The most important of them include better blood supply, oxygenation, and nourishment of working muscles as well as improving the processes of post-workout regeneration.
Glycerol monostearate facilitates the passage of water into the bloodstream and causes it to retain within the blood vessels. Considering the phenomenon of muscle pump, the increase in the total volume of circulating blood makes this effect even more intense. Both citrulline and arginine contribute to the increased production of nitric oxide (NO), which dilates the blood vessels and thus intensifies the muscle pump. L-Norvaline limits the activity of an enzyme that breaks down arginine into ornithine and urea, as a result of which the amount arginine increases and thus strengthens the overall effect.
Niacin has beneficial effects on the nervous system and mental condition as well as it participates in metabolic changes aimed at generating energy. The addition of calcium in the preparation explains its contribution in the initiation of skeletal muscle contraction.
In summary, PROSUPPS Dr. Jekyll Nitro-X is a preparation for pre-workout purpose designed for people sensitive to strong stimulants. The product increases the body's ability to exercise even after a long and tiring day, making the training sessions very intense and effective.
The preparation should be consumed only on workout days. The pre-workout dose should start from half the recommended dose followed by the observation of the body’s reaction. If the effect is not satisfactory enough, increase the dose to the size recommended by the manufacturer.
Despite the fact that the preparation is not packed with strong stimulants, we do not recommend taking it in the evening. The presence of caffeine may cause difficulty in falling asleep.

Vitamin B3 (vitamin PP, niacin, nicotinic acid, nicotinamide) is niacinamide niacin. It is used in interaction with vitamins B1, B2 and B6 in the synthesis of hormones during lactation. It provides proper functioning of the brain and nervous system. It is helpful in inflammatory conditions of the skin. Required for synthesis of sex hormone, estrogen, testosterone, cortisone, and insulin. It does not lose its properties in the manufacturing and storage. The source of acquiring vitamins PP are both products of animal origin (the lean meat, eggs, fish) and vegetable origin (dates, figs, hazelnuts, plums).
Dosage: 2-12 mg / day for children, 14 mg / day for women, 16 mg / day for men and 17-18 mg / day for pregnant or nursing women.
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)
Beta-alanine (β-alanine) is a β-amino acid (the same group to which the I-alanine belongs, but with different chemistries). In combination with histidine, it forms β-alanyl-L-histidine (carnosine) - a antioxidant, chelating and buffering compound. Carnosine reduces the level of hydrogen ions in the cell and allows to extend the physical performance and endurance, it affects biological recovery after exercise. Beta-alanine is available in the form of single component and advanced amino-acid supplements, creatine stacks and nitrogen boosters.
Creatine hydrochloride is an advanced form of creatine formed by combining a creatine molecule with hydrochloric acid. Experts estimate that it is 41 times more soluble in water than creatine monohydrate. It also seems to be much more bioavailable for tissues. Increased absorption means that you need smaller doses to obtain the desired results. In addition, excess water retention and gastrointestinal complaints, which often occur while supplementing with other forms of creatine, are no longer a problem. Creatine hydrochloride also does not require a so-called loading phase.
Creatine hydrochloride produces the same effects as other forms of creatine, including the most thoroughly tested creatine mononhydrate. It effectively stimulates ATP resynthesis, may inhibit myostatin activity and supports a healthy nervous system. It has anabolic and anticatabolic properties and helps improve athletic endurance and performance.
In supplementation creatine hydrochloride is available in the form of powder, which is mixed with water, and capsules. It can be often found in complex pre-workout supplements
Dosage: No official guidelines.
The recommended daily dosage is usually 5 g.
Choline bitartrate a combination of one molecule of tartaric acid and choline, and in this embodiment is a precursor of acetylcholine (neurotransmitter). The human body is able to intracellular synthesis of choline, using the amino acid and vitamin B12. Because of the possibility of shortages of the above mentioned substances, it is necessary to supplement them with supplementation. Choline is a component of lecithin, which is the building substance of cells conditioning the proper functioning of the nervous system, and sphingomyelin, acting as an insulator of nerve tissue. Bitartrate affects the course of fat metabolism. In the sports supplementation of choline, bitartrate is used in the stimulating supplements,, affecting concentration and programs of weight control (fat reduction).
Dosage: 1-3 grams per day.
Caffeine (1,3,7-trimethylxanthine, 1-methylotheobromine) is a purine alkaloid occurring in the natural state in plants (Coffea arabica, Camelia sinensis, Paulinia cupana, Ilex paraguariensis), which acts as a natural pesticide, acting toxic to insects. Peculiar smell and taste also deters herbivores. Caffeine in the body inhibits the adenosine receptors in the brain, fighting fatigue and allowing for action activation. It has a beneficial effect on the metabolism of oxygen, which increases the exercise capacity (strength and endurance) and rapid post-workout recovery. In the sports supplementation, caffeine is used as a stimulant nervous system. It has the thermogenic potential and in combination with other substances (e.g. Polyphenols, both occurring in coffee beans, such as cocoa beans, tea leaves and mate) can effectively participate in the reduction of body fat. It is included in many dietary stimulants (creatine stacks, no-boosters, beverages). It is a component of fat burners. It is also in the form of mono-preparation supplements.
Dosage: 100-600 mg per day. Due to the long release of activity should not be used in the evening, before sleep.
Theacrine is a purine alkaloid which occurs naturally in the fruits of cupuaçu (Theobroma grandiflorum) and the leaves of Camellia assamica. It is structurally similar to caffeine but it has also additional ketone and methyl groups. It also energises, enhances focus and reduces drowsiness and fatigue. In contrary to caffeine, it has more lasting effects and rather does not affect blood pressure. Furthermore, it has been observed that the body develops tolerance to theacrine more slowly and that is why there is no need to increase its dosage to obtain the desired results.
Like caffeine, theacrine can bind to adenosine receptors without activating them. Nonetheless, its effects depend on the dosage. Its high doses block adenosine receptors whereas low doses have the opposite effects – they boost adenosine levels in the hippocampus and that is probably why they may reduce negative effects of excessive caffeine intake. In addition, theacrine modulates dopamine receptors. Their activation leads to higher motivation and enhanced cognitive skills. It is also believed to have analgesic and antioxidant effects.
In supplementation, theacrine is treated as a stimulant. It is used to reduce drowsiness and fatigue and boost mental performance. It is often combined with caffeine to enhance and prolong its effects and prevent the harmful consequences of excess caffeine.
Theacrine is most frequently found in pre-workout supplements and fat burners based on stimulants. Single-ingredient preparations with pure theacrine are also available on the market.
Dosage: No official guidelines.
The most common daily dosage is from 50 to 300 mg. Doses below 50 mg will have a relaxing effect and those around 300 mg a stimulating effect.
Glycerol monostearate is an ester of glycerol and stearic acid. Glycerol (synonyms: glycerol, 1,2,3-propanetriol) tricarboxylic simplest alcohol, used in the production of medicines (as a filler), cosmetics and food industry. Used in higher doses affect water and electrolyte balance of the body, increase exercise capacity and extend the duration of exercise in various sports. In the sports supplementation used for hydration of the muscle cells to increase the volume of muscle during exercise. Glycerol (sugar alcohol) increases the ability to hydrate the phosphorus muscle cells allows better nutrition and increasing the volume. It also has an impact on water and electrolyte balance and energy production. By oral ingestion does not change the glycemic profile of blood. It comes in the form of solid and liquid (glycerine), as mono-preparation supplement or component of pre- and post-workout supplements (creatine stacks, no-boosters), available at www.muscle-zone.pl
What is L-Citrulline?
L-Citrulline is an α-amino acid, ornithine derivative. It was isolated for the first time from watermelon and this is how it gained its name, as citrullus in Latin means watermelon. Citrulline takes part in oxygen processes of energy production during effort, thanks to which it is especially attractive for sportsmen of endurance disciplines. It also takes part in urea cycle, also known as the Ornithine cycle, thanks to which it helps to get rid of excessive amounts of ammonia from the organism.
It converts to l-arginine in kidneys and scientific studies suggest that is increases its level even more effectively than in case of sole arginine. Moreover, the increase of arginine level resulting from citrulline supply is longer and more stable. Thanks to this, it contributes to the increase of nitric oxide and widening of blood vessel lumen. This property makes citrulline useful in preventing cardiological incidents. The positive influence on the circulatory system is also used in case of erection disorders, as increased nitric oxide may initiate more effective blood flow to sex organs.
L-Citrulline is contained in the composition of many pre-workout supplements and NO-boosters directed at the improvement of sports abilities of the organism, which may be found in the offer of muscle-zone.pl.
Arginine is an exogenous amino acid, it is a component of dietary proteins, not always synthesized in the human body in necessary quantity, so it is necessary to deliver it in the form of synthetics. It takes part in the biosynthesis agmatine, creatine and nitrogen oxides. The use of supplements containing arginine before workout increases the exercise capacity (strength, endurance). Used after considerable effort intensifies the transfer of energy and building compounds and intensifies the process of recovery. Used at bedtime in combination with lysine and ornithine enhances the synthesis of growth hormone. takes part in the intrasystemic synthesis of creatine. Arginine (as a precursor of ornithine) is involved in the urea cycle, increases the flow of blood in the circulatory system, increases sexual potency (in a short time after application). It affects the body's immunity preventing infections, and lowers blood pressure. In supplements – usually as alpha-ketoglutarate.
Norvaline - branched amino acids, not-building proteins, valine isomer, inhibiting arginine decomposition, by increasing the content of this amino acid and intensifying its action in the synthesis of nitric oxide. It intensifies the anabolic and catabolic effects of arginine, affecting the growth of functional capacity (strength and endurance) and makes more efficient blood circulation and nutrition of muscle tissue. Not in the form mono-preparation supplements. In the sports supplementation it is a component of the advanced amino acid supplements that contain arginine, no-boosters and creatine stacks. Rarely used for the supplementation due to the high price.
Dosage: usually 50-200 mg / 24h
