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).

Highly effective testosterone booster. I would recommend to men to increase testosterone levels and improve libido and sexual performance. An additional benefit from the use of the product will be increasing the resistance to stress by regulating the secretion of cortisol and increase the life energy. According to the manufacturer optimal dose includes 2 or 4 capsules per day. They can be divided and taken at intervals of a few hours. Preferably on an empty stomach, in the second half of the day. I suggest you to take the last dose 30-60 minutes before bedtime. Magnesium contained in the product has a slightly calming and relaxing effects, and a positive effect on sleep. I know from experience that the person receiving the product at night they sleep better, wake up refreshed and regenerated. It should not be taken with food. It can not be taken with calcium, because it weakens its absorption. There are no clear guidelines as to how long you can take the preparation. It stimulates the production of testosterone, so after a few months of use, you can take a short break.

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
Asparaganian magnesium (chelate magnesium and aspartic acid) is an organic magnesium form characterized by absorption and stability in the body. Magnesium is actively involved in energy conversion (necessary in the process of ATP). Intracellular cation, stored in the bones, partly in soft tissues and minimal quantity in the extracellular fluid. Maintains a proper bone structure, nucleic acids and chromosomes. It is an activator of enzymes involved in the synthesis of protein, stabilizes cell membranes, conducts nerve impulses and increases contractility of nerve fibres.
Deficiencies of magnesium in the body are causing disorder of the immune system and water-electrolyte balanace, causing greater susceptibility to stress, irritability and insomnia. Magnesium deficiency can cause cardiac arrhythmias, uncontrolled muscle contractions, numbness in the limbs.
Asparganian Magnesium is a component of the mineral preparations (including ZMA), vitamin and mineral and pro-testosterone supplements used in sports supplementation.
Dosage: based on Mg ions, 100-500 mg per day.
Zinc (chemical element from transition group 12) belongs to the trace elements, it helps maintain acid-base balance of the body, protein, energy, lipid and carbohydrate metabolism. It provides bone metabolism and transport of oxygen. It protects the body against free radicals. Necessary for the proper operation of the senses of taste and smell. Positive impact on the process of insulin metabolism in the pancreas. It supports visual adaptation to the dark, has a significant influence on brain function. It is helpful in the treatment of infertility and mental illness.
Zinc deficiency leads to decreased immunity, and growth retardation. Zinc deficiency can occur in case of excessive consumption of simple sugars. In the case of hormonal therapy of women with irregular menstruation, the therapy should be associated with increased consumption of zinc. It can be found in food like: beans, eggs, carrots, beef and pork meat, milk, nuts, citrus fruits, seafood, rice, cottage cheese, lettuce.
Dosage: Daily 12-15 mg zinc. Exceeding the daily dose of 20 mg cause symptoms of poisoning of the body.
Exogenous methionine is an amino acid containing sulphur in its composition. It provides multi metabolism, with the indispensable help of vitamin B6. Participates in the synthesis of phospholipids (e.g. Lecithin), carnitine responsible for transport in the body of long-chain fatty acids, burned in the mitochondria cells (organelles in cells with a separate kernel), along with cystine forms cysteine. 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.
