MZ-Store Pre-workout is a pre-workout supplement whose simple composition is its greatest asset. Thanks to the use of optimal portions of exclusively most effective compounds that promote the training efficiency, this product is reliable support in situations of increased effort.

On the market, there are plenty of pre-workout supplements containing proprietary blends which conceal the content of individual ingredients. The active substances themselves contained in such products are also often questionable. They have little or no scientific evidence for their activity, whereas their complicated, professionally-sounding name does not entail the actual effectiveness. The pre-workout created by Muscle Zone is the complete opposite of such supplements.

The formula of this preparation consists of only well-known substances, the effectiveness of which has been confirmed by not only numerous scientific evidence but also by the experience of athletes. The nutrition label is clear, thus making the user completely aware of what he or she consumes. The combination of four effective active ingredients in optimal doses ensures the maximum increase of training capabilities. The composition of the product consists of:

Caffeine – purine alkaloid responsible for the stimulating effect of the known-for-centuries infusions based on coffee or yerba mate. Caffeine owes its popularity to multi-directional effects. First of all, it is a competitive inhibitor of adenosine. This means that it is able to bind to the receptors of this nucleoside without stimulating them. As a result, it limits the transmission capacity of adenosine, whose role in the brain is to signal fatigue and limit the activity of neurons.

Secondly, it is a competitive inhibitor of cAMP-phosphodiesterase, an enzyme that converts cyclic adenosine monophosphate to a biologically inactive, non-cyclic form. In this way, caffeine promotes the concentration of cAMP in the body, which increases the synthesis and activity of epinephrine with a strong stimulating effect. The high amount of cyclic adenosine monophosphate also accelerates myocardial function.

Finally, the effectiveness of caffeine on the promotion of exercise capacity is also possible through its metabolites. Theophylline, through the diastolic action towards bronchial smooth muscle, promotes respiratory efficiency. In turn, theobromine shows a vasodilating effect, promoting the transport of blood with nutrients to the peripheral tissues of the body.

Citrulline – is a non-protein amino acid commonly found in watermelons, known for its ability to cause the feeling of the so-called "muscle pump". This phenomenon is the result of the vasodilating activity of this amino acid. Supplementation with citrulline increases the concentration of arginine in the body, which in turn leads to the increased synthesis of nitric oxide. As a consequence, the lumen of the blood vessels is widening. This allows intensification of blood circulation, which is associated with the improved exchange of nutrients and metabolites in the tissues. The increased amount of energy compounds supplied to working skeletal muscles allows them to work more intensively, which in turn facilitates generation of stronger training stimuli.

AAKG – arginine alpha-ketoglutarate, i.e. a combination of alpha-ketoglutaric acid with arginine that increases the absorption of this amino acid. The content of AAKG in the supplement complements the activity of citrulline. The combination of these two amino acids comprehensively promotes the formation of a muscle pump, thus increasing exercise capacity.

Arginine may also support exercise capacity due to its presence on the creatine synthesis pathway. The appropriate amount of arginine promotes the efficient production of this highly crucial – for energy metabolism – compound.

Beta-alanine – an amino acid that demonstrates its effectiveness through the promotion of carnosine levels in the body. Carnosine, unlike beta-alanine, is unable to penetrate cell membranes, making its direct supplementation ineffective.

Beta-alanine binds with histidine in the body cells to form a carnosine whose main task is to buffer the acid-base environment. This is particularly important in myocytes during physical exercise, which causes increased production of lactic acid causing pain that limits physical capabilities. Carnosine neutralizes its action, allowing for a longer and more intense workout. The optimization of pH inside the cells also favors their functioning, supporting regenerative processes.

To sum up, MZ-Store Pre-workout is a formula based on ingredients whose effectiveness has been confirmed by numerous experiences of athletes and research. It increases training capabilities and stimulates, allowing for an increase in training efficiency and overcoming the succeeding barriers on the way to the desired goal.

Arginine alpha-ketoglutarate


Arginine alpha-ketoglutarate (AAKG) is a salt glutaric acid and arginine. The presence of these compounds results in intensification of the operation of each of them. Arginine alpha-ketoglutarate improves the bioavailability by stimulating the decomposition to CO2 and H2O, which means that it becomes a precursor in the synthesis of nitric oxide. It has anti-catabolic properties enhancing anabolism. Enhances the functioning of the insulin hormone, insulin-mimetics IGF-1) and somatotropin growth hormone.
AAKG is part of the pre-workout supplements (improving muscle blood flow and increasing the exercise capacity (strength and endurance)), as well as improves the recovery process after training. Most often used to increase the synthesis of nitric oxide (supplements pre- and post-workout), increasing muscle blood flow and regeneration. Particularly valued by the representatives of power sports, power and strength sports and strength athletics. Used very often in the rehabilitation of sports injuries.


Citrulline malate


Citrulline Malate is formed by combining molecules of the citrulline amino acid and molecules of malic acid in one molecule, which has the chemical stability and is well soluble in liquids. Ionized malic acid has the ergogenic potential, providing a complementation to the citrulline potential of with new properties. It improves the exercise capacity and reduces the feeling of fatigue, and its supplementation is beneficial at any level of fitness. It affects the acid-base balance. It should be used by people who practice sports: strength, endurance and mixed strength-endurance. To achieve the best results, a dose of Citrulline Malate 6 g / 24h is recommended.
It is available as single-ingredient supplements and multi-component supplements (creatine stacks, no-boosters, amino acid supplements). It is used in the periodic, cyclic and constant supplementation.
Dosage: 3-8 g daily (in divided doses). The optimal dose to achieve beneficial results, proven experimentally, is 6 g / 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.




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




Magnesium (element from the group of alkaline earth metals, atomic no. 12, a chemical symbol - Mg), one of the most important health microelements, participates in the synthesis process of the disintegration of high energy compounds and processes of transformation of hydrocarbons and fats. It affects the dilation of blood vessels and lower blood pressure, prevents hypercoagulable state. Shortages affect cardiac arrhythmias, malignant muscle cramps, insomnia and anxiety. It is a component of many dietary supplements and found in foods such as whole grain bread, legumes, buckwheat, rice, fish, meat, as well as chocolate, cocoa and nuts.
Dosage of 100 - 500 mg / day
