You have got questions about the product

  • Advanced pre-workout formula
  • Strongly stimulates and increases efficiency
  • Intensifies fat loss
  • Supports the production of testosterone
  • Elevates strength and muscle pump

Muscle Metabolix SPR HMN is a pre-workout for advanced athletes, which not only contains numerous training boosters and potent ingredients that increase testosterone levels but also offers muscle regeneration support.

The preparation is based on three core proprietary blends; Instant Response Cognitive Energy System, containing stimulants; Muscle Active System, increasing the exercise capacity; and TST Testosterone Support, supporting the absorption of active substances and increasing the level of testosterone. Each of the formulas has been developed in such a way as to enhance each other's effects and thus fully meet all the needs of the most demanding athletes.

Muscle Active System is a blend of the most thoroughly tested and, at the same time, the most effective compounds supporting muscle performance and strength, without the addition of stimulants. The creatine monohydrate and the patented form of beta-alanine, i.e., Carnosyn®, which are found in the formula are components that increase the resources of metabolically active compounds, thanks to which they can improve aerobic capacity and the ability to generate strength in muscle tissue. The whole is complemented by agmatine sulfate, which is the most effective nitric oxide booster, ensuring a spectacular muscle pump. Besides, agmatine reduces the development of body's tolerance to stimulants.

Instant Response Cognitive Energy System is a real bomb of stimulants, which not only significantly increases energy levels, but also noticeably increases muscle strength and the efficiency of using fat as an energy substrate. The substances such as 1,3-dimethylamylamine (DMAA), 2-amino-6-methylheptane (DMHA), yohimbine hydrochloride, huperzine A or caffeine create the highest level of stimulation and fat burning. Due to the varying mechanisms of action, these substances intensify each other's effects, simultaneously multiplying the feeling of arousal and extending its duration.

TST Testosterone Support is a blend of the patented black pepper extract, Bioperine®, and N-methyl-D-aspartic acid. The first ingredient improves the absorption of active substances and exerts a thermogenic effect, whereas the latter is a proven booster of testosterone, a hormone that determines both sports performance as well as libido and well-being.

To sum up, Muscle Metabolix SPR HMN is ideal preparation for active people who want to move their workout to a higher level or are looking for support in fat loss.

Creatine monohydrate


Creatine monohydrate is a popular and cheapest form of creatine used in sports supplementation in Poland. This is a molecule, in which are bound: creatine molecule with a molecule of water. It has a high bioavailability and tissue velocity saturation. Supports the exercise capacity (strength and endurance), accelerates muscle growth and regeneration after training exercise. Transport of creatine into the muscle cells is supported by the insulin hormone. For better effect of saturation of the tissues, a diet increasing the content of insulin in the body is indicated (carbohydrate and high protein diet) and supporting nutrients and supplements (Dietary carbohydrate and carbohydrate-protein, insulin ALA, d-pinitol or taurine). Creatine monohydrate is present in the form of mono-preparation supplements (capsules, powders, tablets) and multicomponent supplements (i.e. as a component of creatine stacks).
Dosage: depending on the form of supplement, the type of exercise and weight, normally are used one of the following models of creatine supplementation:
- cyclic supplementation : 5-10g per day in 1-3 portions during the day, 3-5g per dose. The length of the cycle for 4-8 weeks.
- cyclic supplementation with saturated phase: the first 5-7 days after 20-30g daily in 4-6 doses of 4-6g per serving, then the maintenance phase 2-10g per day in divided doses. The length of the cycle 4-8 weeks
- constant supplementation: 0,03-0,05g per kg of body weight for an extended period of time.




CarnoSyn® is a patented, highly bioavailable form of beta-alanine, designed by Natural Alternatives International (NAI). Its effectiveness has been confirmed by numerous clinical tests. To date, more than 55 independently reviewed studies on the CarnoSyn® properties have been published. CarnoSyn® Beta-alanine is found in advanced, multi-component peri-training formulas, but it can also be purchased as a mono-preparation.

The active ingredient of CarnoSyn® is beta-alanine. This amino acid is used in the body mainly for the production of carnosine, which is responsible for buffering of the drop in pH, associated with the formation of lactic acid in muscle cells during physical exertion. The increased level of carnosine results in better tolerance to effort and growth of muscle strength and endurance, which delays fatigue and prolongs the ability to continue exercise.

Dosage: as to ensure the optimal effect of CarnoSyn®, NAI recommends using 3.2g of the product per day for a minimum period of 4 weeks (the so-called loading phase). In addition, the manufacturer suggests dividing this dose into two portions, (1.6 g each), which helps to avoid the symptoms of paresthesia that sometimes occur following administration of beta-alanine.





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.


Agmatine sulfate


Agmatine sulfate is a compound of agmatine, and hence the substance resulting from the processing of arginine.
It meets the body's range of functions, including increases levels of nitric oxide responsible for vasodilation and thus improves blood circulation. It stimulates the release of growth hormone and testosterone. It increases the amount of nutrients delivered to the muscles, and normalizes blood glucose levels, thereby mimicking the operation characteristic of insulin; improves the functioning of the central nervous system; fights free radicals; reduces depot body fat, and also affects the metabolism of calcium, thus providing a better functioning of the heart, brain and muscles.
Dosage: 500-1500 mg, the best half an hour before training.



Yohimbine is a natural component of the indole alkaloid yohimbine, ingredient of bark of yohimbe (Corynanthe yohimbe), a recognized aphrodisiac and increasing potency mean. It stimulates the nervous system by blocking the adrenergic receptors alpha-2. Tree bark of yohimbe is also a source of alkaloids (isoyohimbine, aloyohimbine), which can enhance its performance. With the right dosage, taken with caffeine on an empty stomach and a longer period before taking a meal, it enhances the process of lipolysis due to increased levels of norepinephrine in the body.
In the sports supplementation
it helps to reduce body fat (especially in programs of weight control and its composition), taken before physical activity. It comes in the form of mono-preparation supplements, extracts from yohimbe tree bark, synthetics and in supplements with thermogenic effect. Available for purchase at
Dosage: No specific dosage standards. Some sources give optimal dose of 0.2 mg / kg
of body weight (usually used at 5-10 mg per day).
