Product Description

Tongkat Ali (Eurycoma longifolia)

Tongkat Ali works by stimulating the body to produce more testosterone. Unlike so many other testosterone boosters, this plant doesn’t introduce hormones from outside the body. On the contrary, Tongkat Ali makes the body produce its own, natural testosterone.

(Wiki) A 2010 ethnopharmacological inventory study on Eurycoma longifolia stated: “The plant parts have been traditionally used for its antimalarial, aphrodisiac, anti-diabetic, antimicrobial and antipyretic activities.

In an experiment conducted on male rats, it was found that Eurycoma longifolia increases sperm count. The authors also reported that the plasma testosterone level of Eurycoma longifolia extract treated rats “was significantly increased when compared with that of the control and infertile animals. Another group of scientists confirmed that Eurycoma longifolia has the capacity to “reverse the inhibitory effects of estrogen on testosterone production and spermatogenesis.”

Eurycoma longifolia Jack (ELJ), which contains quassinoids such as eurycomalacton, eurycomanon, and eurycomanol, has been reported to have aphrodisiac properties and to increase testosterone levels in men.

Previous studies have established that the testosterone supplementation increases fat free mass, muscle strength, and muscle mass, which are important for physical function andathletic performance.

Thus, the objective of this study was to investigate the effect of the increase in testosterone levels, obtained by administration of ELJ, on body composition and muscle strength and size in man. Fourteen healthy men performed an intense strength training programme with initial load of 60% RM (2 sets of 10 repetitions with 1 minute rest between, for 10 stations) on alternate days for five weeks.

Simultaneously, seven men were randomly selected to consume 100 mg/day ELJ water soluble extract, and seven men received placebo. The intensity of the exercise was increased by 10% RM/week. Body composition, arm circumference, one repetition maximum (1 RM), and surface electromyography (sEMG) activity were measured and recorded one day before and after the five weeks of supplementation and intervention. The lean body mass of the treatment group showed a significant increment, from 52.26 (7.18) kg to 54.39 (7.43) kg (p = 0.012), but no significant changes in fat free mass were observed in the placebo group.

Percentage body fat was significantly decreased in the treatment and placebo group, from 31.30 (5.48)% to 28.44 (6.43)% (p = 0.01) and from 22.83 (2.43)% to 21.33 (2.35)% (p = 0.001) respectively. The 1RM test showed a significant increase from 73.71 (16.63) to 78.71 (17.0) kg (p = 0.006) in the treatment group and from 77.29 (8.9) to 79.43 (8.8) kg (p = 0.011) in the placebo group.

The increase in strength in the treatment group was larger than in the placebo group (6.78% and 2.77% respectively). The mean frequency of sEMG on the biceps in the treatment and placebo groups decreased significantly, from 121.77 (40.0) to 90.47 (64.6) ?V (p = 0.012) and from 127.95 (30.9) to 98.8 (50.1) ?V (p = 0.036) respectively.

The treatment produced 2.92% greater reduction in electrical activity of the muscle measured at the end of the experiment compared with placebo. The mean arm circumference of the treatment group increased significantly by 1.8 cm after the supplementation, from 30.87 (1.88) to 32.67 (1.96) cm (p = 0.011), but there was no significant increase in the placebo group.

The results suggest that water soluble extract of Eurycoma longifolia Jack increased fat free mass, reduced body fat, and increased muscle strength and size, and thus may have an ergogenic effect. Further investigations are warranted.




Ginkgo Biloba:

Ginkgo improves energy flow at a cellular level by increasing the production of adenosine triphosphate (ATP) in your body. (ATP is the fuel the cells need to function) ATP aids the brain in metabolizing glucose for energy, which improves mental function. When you feel mentally drained, ginkgo is the herb for you.




Panax Ginseng:

Panax ginseng root extracts have been used in traditional Chinese medicine (TCM) for thousands of years as a tonic indicated for its beneficial effects on the central nervous system, protection from stress, anti-fatigue action, enhancement of sexual function, and acceleration of metabolism.

At the present time there is no evidence that Panax Ginseng actually boosts physical endurance. However, there is many studies that proves that Panax Ginseng reduce cronic fatigue, improve cognitive perfomance and better life quality in general.
