Description
  • A complex of ZMA, Tribulus and Tongkat Ali (!)
  • Efficient testosterone booster (!)
  • Increases libido and sexual performance
  • Boosts vitality and energy for life
  • Alleviates stress symptoms and reduces cortisol
  • Has an adaptogenic and toning effect

Now Foods TestoJack is a dietary supplement with a standardised LJ100 Tongkat Ali extract which worked as an aphrodisiac, fought stress and increased the level of free and total testosterone during tests. The product has also been enriched with a Tribulus terrestris extract and a complex of magnesium, zinc and vitamin B6, i.e. ZMA.

Tongkat Ali (Long Jack; Eurycoma longifolia) - an extract of an Asian plant used for centuries as a strong aphrodisiac and a tonic. It is a source of alkaloids and glycosides (including beta-carbolines) and it affects the activity of male sex hormones. The extract increases the organism's immunity and resistance, has a beneficial effect on the mood and improves sexual functions.

Tongkat Ali increases the level of testosterone (!) - research review:

Supplementation with a standardised TA water extract in the amount of 200mg per day for a month caused the restoration of the right testosterone level in 90% of 76 patients who suffered from late onset hypogonadism (a testosterone deficiency syndrome connected with aging)1.

Monthly supplementation of TA in 63 subjects (men and women) resulted in the reduction of stress symptoms, reduced concentration of cortisol in saliva (-16%) and an increase in the level of testosterone by 37% in average 2.

Supplementation with the TA extract in the amount of 400mg per day in 12 physically active seniors for the period of 5 weeks resulted in a significant increase in strength and the total and free concentrations of testosterone in men and women3.

Tribulus terrestris - a medicinal plant broadly used as an aphrodisiac. It is traditionally believed to be a herb that improves sexual performance in men. It can have medical application in the treatment of urination disorders, inflammations of the prostate, hypertension and hypoercholesterolemia. It stimulates spermatogenesis in men and ovogenesis in women. It increases nitrogen retention and alleviates andropause symptoms. It has also been reported that after treatment with the Tribulus terrestris extract, the sperm cell number, vitality and mobility are increased and ejaculation is noticeably better.

Zinc - (as aspartate and zinc monomethionine) - an essential microelement (trace element), present in the active centres of about 200 enzymes, thus influencing the process of many metabolic reactions. It directly participates in androgen synthesis by activating 17-beta-reductase - the enzyme that catalyses the transformation of androstenedione into testosterone. Moreover, it is capable of increasing the level of total and free testosterone and decreasing the concentration of its metabolites.

Magnesium (as magnesium aspartate) - a mineral essential to the normal functioning of the organism. It performs the function of an activator for many enzymes, directly or indirectly affecting metabolic pathways. It is a component of bones, it reduces the degree of cell colloid hydration, participates in transmitting signals in the nervous system. Magnesium ions play an important role in maintaining the osmotic pressure of the blood and other tissues.

Vitamin B6 (as pyridoxine hydrochloride) - occurs in six forms which, as a result of enzymatic reactions, are transformed into pyridoxal phosphate (the biologically active form of vitamin B6); it is necessary for the synthesis of neurotransmitters (dopamine, serotonin and noradrenaline) and haemoglobin (red blood colourant) and facilitates the absorption of magnesium from the gastrointestinal tract. Moreover, it takes part in many metabolic transformations as a coenzyme, mainly in the transformations of amino acids (transamination and decarboxylation) and muscle glycogen (glycogen phosphorylase).

As clinical studies confirmed, supplementing the deficiencies of magnesium, zinc and vitamin B6 contributes to a significant increase of free and total testosterone in blood serum.

To sum up, Now Foods TestoJack is a product recommended for men in order to increase the level of testosterone, libido, sexual performance, stress resistance and everyday vitality.

It is in the body antioxidant function. Natural source of acquisition of methionine are high-protein foods of animal origin (eggs, meat, fish), vegetable (sesame seeds, grain products). Available in all protein and carbohydrate protein and amino acid supplements such EAA and contain so-called all-day amino acids, supporting the liver preparations and cosmetics supporting the growth and condition of hair, skin and nails.
