You have got questions about the product

  • An extremely effective composition of strong stimulants supporting weight loss
  • Improves cognitive functions – memory, concentration, perception
  • Improves circulation in muscles and increases respiratory efficiency
  • Based on natural plant extracts
  • Suppresses appetite and boosts a lot of energy
  • Promotes thermogenesis and lipolysis

Hi-Tech Pharmaceuticals Black Widow is a highly advanced composition of effective ingredients accelerating fat reduction. The product has been developed to maximally support the loss of unnecessary kilograms. A carefully selected thermogenic and lipolytic substances as well as substances stimulating the increase of the metabolic rate not only perfectly reduce fat and suppresses appetite, but also exerts energetic effects.

One capsule of the product provides a unique blend of substances, consisting of:
Ephedra extract – it is an extract from the leaves of the plant belonging to the Ephedraceae family. This extract is rich in numerous substances with a stimulating effect on the nervous system, supporting fat breakdown and thermogenesis.

The substances contained in the extract are strong stimulants that effectively facilitate losing weight. Besides, they accelerate metabolism, increase blood pressure and heart rate, as well as expand the airways, making breathing easier. As a result, our body is more efficient and better prepared for physical effort, because the muscles are more quickly and efficiently supplied with oxygen and nutrients.

Importantly, this extract does not contain dangerous to health ephedrine or pseudoephedrine, and yet, it is equally effective.

Senegalia Berlandieri extract is a rich source (up to 200mg in 1 capsule) of phenylethylamine alkaloids, such as methylsynephrine or phenylethylamine (PEA). These compounds may act as neurotransmitters, causing psychophysical stimulation, which is manifested in increased motivation, pain resistance, and general mobilization of the body to physical effort.

Often observed in runners, the effect of the so-called runner's euphoria, which is manifested by a sudden inflow of strength and a desire to continue running, despite the exhaustion of the body, is explained by the release of small amounts of phenylethylamine alkaloids in the brain.

2-Aminoisoheptane HCl, also known as dimethylhexylamine (DMHA), is a strong stimulant. The effect of DMHA on the body is similar to this of DMAA (geranium), except that the latter exerts a much stronger action and is banned in many countries.

DMHA was originally used as an asthma medicine because it dilates the bronchi, which makes breathing easier and improves respiratory function. Hence, oxygen transport to the working muscles increases. What is more, 2-aminoisoheptane exerts similar effects to catecholamines (adrenaline, dopamine) – it raises blood pressure by constricting blood vessels, which also increases the rate of oxygen supply to tissues.

Theobromine – an alkaloid found naturally in cocoa, coffee or tea. It exerts a caffeine-like effect, i.e. it stimulates the nervous system, causing arousal and improving cognitive functions. Moreover, theobromine may increase lipolysis as well as increase blood pressure and heart rate, thus improving the blood supply to organs, including muscles.

Studies have also shown that supplementation with theobromine-containing products supports the stabilization of total cholesterol, as well as LDL and triglycerides.

Bitter orange extract and green tea extract are plant extracts that provide the body with extremely valuable substances. Antioxidants derived from green tea slow down the aging process, protect cells against the harmful effects of free radicals, whereas the polyphenols it contains have proven pro-health effects.

Furthermore, synephrine derived from bitter orange is a stimulant that is often used to treat obesity because it promotes weight loss while providing a noticeable energy boost.

Yohimbine extract is an extract from the bark of the Yohimbe tree that provides large amounts of yohimbine – an alkaloid with strong stimulating properties. The action of yohimbine is based on blocking alpha-2-adrenergic receptors, which is manifested by increased secretion of noradrenaline. This, in turn, results in e.g. an accelerated heart rate, increased blood pressure, and overall mobilization of the body, all of which constitute a perfect preparation of the body for physical effort.

What is more, rodent studies show that yohimbine may reduce appetite, thus helping to lose weight and maintain healthy body weight. This alkaloid can also be used as a natural aphrodisiac because it increases libido in both men and women.

Naringenin – a flavonoid that occurs abundantly in grapefruit. Studies show that the compound can induce apoptosis of adipocytes (fat cells), as well as lower plasma and liver cholesterol. Naringenin also exerts slight antidepressant and anti-inflammatory effects.

Caffeine is a methylxanthine commonly found in coffee and tea. It stimulates the body and reduces fatigue. Besides, it improves mood and concentration, as well as increases physical efficiency.

Furthermore, the substances arising as a result of caffeine metabolism, such as paraxanthine, intensify lipolysis, releasing glycerol and fatty acids as an additional source of energy. They may also dilate blood vessels and increase the frequency of heart contractions.

In summary, Hi-Tech Pharmaceuticals Black Widow is the top quality preparation providing a solid dose of stimulants. The supplement is a comprehensive blend of effective substances that promote the loss of body fat and increase the efficiency of the body by affecting the circulatory and respiratory systems. Improved blood supply to the muscles and more efficient oxygen transport ensure better preparation of the body for heavy physical exertion, which further promotes the performance of exercises aimed at weight reduction.

Proprietary blend


Proprietary blend - is a complex of bioactive ingredients in the proportions, which are covered by the manufacturer's patent. According to the law in force in Poland, the components of the blend are known, and , by the place on the packaging, you can identify which components are in bigger amount (the components are listed in the decreasing order of amounts).
Proprietary blends are used in many food supplements, such as creatine stacks, no-boosters, fat burners and pro-testosterone supplements, improving libido.


Senegalia Berlandieri


Senegalia Berlandieri is a source of numerous alkaloids, among which the most numerous are: N-methyl-N-phenylamine, tyramine and phenylethylamine. Similarly to Acacia Rigidula, Senegalia Berlandieri promotes the required growth of energy and mood improvement, which it owes to its influence on increasing the level of dopamine and adrenaline in the organism. Senegalia Berlandieri extract also intensifies lipolysis and stimulates metabolism.

Phenylethylamine derivatives (PEA) contained in the extract of this plant are responsible for the effect of good mood (they stimulate the secretion of serotonin and dopamine), cause positive attitude to life and increase the willingness to act.

Thanks to its properties stimulating the nervous system, optimizing well-being and intensifying lipolysis, the extract from Senegalia Berlandieri is the component of many extremely effective and strong pre-workout boosters, at the same time being an effective DMAA substitute.



N-methylphenethylamine – a neuromodulator which is a derivative of phenethylamine, occurring naturally in the human body. Structurally, it a position isomer of amphetamine. As an antagonist of hTAAR1 receptors, it has a significant stimulant effect on the body, thereby mimicking adrenaline activity.

It exerts strong energising properties, boosts energy levels, reduces fatigue and may increase dopamine levels. Because of that, it is a frequent additive to preworkout supplements  that is responsible for promoting physical performance and increasing levels of motivation.

N-methylphenethylamine can be found in fat burners. It provides energy in an extremely difficult fat reducing diet and may also accelerate metabolism. Some sources indicate that N-methylphenethylamine curbs the appetite.

This compound has a short half-life and that is why it can be expected to have a rather short period of activity in the body. Because of that, it will be effective especially when consumed quickly before training.

Phenethylamine (PEA)


Phenylethylamine (PEA) - an organic compound present in the natural form (e.g. in chocolate) and synthesized in the human body from the amino acid and phenylalanine. As a neurotransmitter and neuromodulator affects the nervous system, increases the amount of dopamine and norepinephrine. The only disadventage is too rapid degradation by the enzyme MAO-B in the case of oral administration, thus sometimes modified components retarding disintegration. In the sports supplementation PEA used to improve mood, stimulate, increase thermogenesis, pre-workout. It is also a component in fat burners. Overuse and high frequency of taking PEA may reduce mental form.
Dosage: 250-500 mg per day.

2-Aminoisoheptane (DMHA)


2-Aminoisoheptane (DMHA) - a compound, which gained its popularity as a result of DMAA delegalization. It is used as a safer, legal substitute of dimethyl amylamine and it is equally effective. It shows stimulating properties, increases intellectual abilities, promotes cognitive functions and may also limit appetite.

This mechanism of activity od DMHA is based on its ability to promote the concentration of noradrenaline and dopamine in the organism. The first of these compounds belong to the group of catecholamines with strongly stimulating influence on the human organism. It increases heart rate, promotes physical efficiency, limits fatigue. Dopamine, in turn, is present in the center of motivation, its high level is conducive to influencing respiratory abilities.

From the physiological point of view, DMHA is able to widen the walls of bronchi, which positively influences respiratory abilities. Thanks to this, the organism achieves higher effort ability. From the point of view of workout, it allow to generate more intensive development stimuli. 2-Aminoisoheptane also facilitates workout by increasing the pain threshold.



Theobromine (3,7-Dimethylxanthine) is a purine alkaloid, poorly soluble in water, present in cocoa beans, as well as the leaves of yerba mate, tea, coffee, cola and peanuts. It is a diuretic, lowers blood pressure and improves brain function (dilates the blood vessels of the brain). Also expands the blood vessels throughout the circulatory system, preventing atherosclerotic changes. Sometimes it is used in slimming diet. Combined with caffeine and polyphenols becomes thermogenic. In the sports supplementation formulations containing theobromine are used diuretics and fat burners. It is a component of thermogenics, pre-workout creatine stacks, as well as nitrogen boosters.

Citrus aurantium extract


Citrus aurantium extract (Bitter orange extract) is widely used in weight reduction process, among athletes, active individuals and people with so called sedentary life-style. It is a source of synephrine and octopamine, which in combination with caffeine and polyphenols contained in green tea affect lipolysis, releasing fatty acids from adipocytes, causing increased energy expenditure, burning them in the sources of cells vital energy (mitochondria). It became popular after the banning ephedine (dangerous for the body) by WADA .
The extract of bitter orange is part of the weight loss
supplements (I.e. thermogenics), pre-workout creatine stacks and nitrogen boosters.
Dosage: No specific standards of daily consumption. At high hypertension and
with medicines containing a statin, extract of bitter orange should not be used.




Synephrine is an organic compound from harvested on an industrial scale the fruit of bitter orange (Citrus aurantium). Citrus auratuim extract (extract of bitter orange) is widely used in the process of weight reduction, both among athletes, active individuals, as well as leading the so-called. "sedentary lifestyle". It is a source of synephrine and octopamine, which in combination with caffeine and polyphenols contained in green tea affect lipolysis, releasing fatty acids adipocytes, by causing increased energy expenditure, burning them in the sources of vital energy cells (mitochondria). It is popular on the banning of ephedra by WADA (dangerous for the body). Contraindication to use preparations against people with hypertension. In the sports supplementation is available in body mass reduction and sculpting programs, as a thermogenic, creatine stacks and nitrogen boosters ingredient.
Dosage: No standards unit consumption. In the supplementation - customarily - 10-30 mg


Green tea extract


Green tea extract is a concentrate that contains biologically active compounds: polyphenols (e.g. catechin, in the form of EGCG - epigallocatechin gallate), having antioxidant properties and a small thermogenic potential, modifies the action of testosterone metabolites, DTH. Green tea extract is an ingredient of many sports supplements containing fat burners, having pro-health and vitaminizing effect; also for those with low physical activity as an antioxidant and slimming supplement. Available either as mono-preparations, ready drinks, and above all as an extract.
Dosage: 200-500 mg per day (depending of the content of other active bio-components).




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).




Naringin - flavonid glycoside occurring in grapefruit and bitter orange, metabolized in the body to form of narginin. Metabolism provides nutritional, antioxidant and lowering bad cholesterol activity. Lowering the level of cortisol (stress hormone), it has catabolic effects on muscle tissue, but it can negatively affect the insulin metabolism. Naringin included in the extracts of citrus fruits, vitaminizing, fat burners, 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
