PRICE: $30.95 for each 60 capsule bottle (300mg per capsule) Barlowe's Herbal Elixirs is now offering the finest Tongkat Ali Extract in the world. It is Sumatra Pasak Bumi Brand, and a 200:1 (or 1:200) extract, meaning that 200 kilograms of the wild-harvested old growth roots are utilized to produce one kilogram of extract. This product comes from the island of Sumatra in Indonesia. Sumatra is the only place left in the world where harvestable quantities of wild Tongkat Ali remain. Note: Barlowe is offering this product (60 capsules with 300mg of the 200:1 extract per capsule) in a pure, unadulterated state at what he believes is the lowest price on the market.  Due to the extremely high cost of bulk quanties of this Tongkat, his margins are quite thin. Thus, on this 200:1 extract, no returns or refunds are permitted.   This product is primarily utilized as an aphrodisiac and as a treatment for erectile dysfunction. However,  it increases testosterone levels, so it is a great tonic for youthfulness and bodybuilding as well. Since this product raises free testosterone levels in the blood, it is a good idea to take Nettle Extract with it, as the Nettle prevents the testosterone from binding with the Sex Hormone Binding Globulin (SHBG) in the blood stream. Some clients report a reduction in back pain with the use of this Tongkat Ali Extract. These vegetable-derived capsules (vegetarian, Kosher and Halal certified) are filled by hand with a manual encapsulation machine, not with a high speed automatic machine, and thus, only pure, unadulterated Tongkat Ali 200:1 Extract is in the capsules. Capsules produced with high speed machines in herbal remedy and vitamin "factories" contain several other ingredients, including preservatives because so many bottles of product are produced at one time, and lubricants to ensure that the machines will run faster and more efficiently. Check their labels! Also, Barlowe's Herbal Elixirs is one of the very few manufacturers that still package their products in glass whenever possible, even though glass is more expensive.  Barlowe believes that chemicals can leach out of plastic containers and contaminate the contents, and that the use of glass is much better for the environment. Tongkat Ali is a popular folk name for Eurycoma longifolia, a medium size slender tree reaching 10 metres in height. The name Tongkat Ali means “Ali’s walking stick.” Another folk name for the plant is Longjack. Tongkat Ali is native to Malaysia, lower Burma, Thailand, and Indonesia. The root is employed as a traditional remedy for the treatment of malaria, high blood pressure, fevers, fatigue, loss of sexual desire, and impotence. Tongkat Ali is a scientifically studied plant which holds up brilliantly under close scrutiny. The root contains a plethora of beneficial compounds, including potent protective antioxidants which inhibit cellular aging. Other phytochemicals in Tongkat Ali are anti-viral, anti-malarial, and anti-cancerous. Others combat high blood pressure. Quassinoids in the root prove twice as potent as aspirin against fevers. Most importantly, Tongkat Ali extract increases the formation of testosterone levels fourfold. Increasing testosterone levels is the main objective from a sex drive standpoint. Testosterone is the most important of the male sex hormones, which are known as androgens. Testosterone plays a key role in the development and maturity of male sex organs. The hormone promotes secondary sex characteristics including the appearance of facial hair, enlargement of the larynx (producing a deeper voice), sexual desire and sexual behavior. But testosterone is not just a sex booster for men. Women also produce testosterone, - about 5 to 10% the amount produced in men. In women, this vital hormone also fans the flames of ardor, and increases sensitivity in the erogenous zones. In both sexes, testosterone stimulates metabolism, promotes lipogenesis (burning of fat), increases the formation of red blood cells, and accelerates muscle growth. With Barlowe's Tongkat Ali 200:1 Extract you can boost your testosterone levels back up to more youthful levels, increasing both sexual desire and ability. Men will attain stronger, harder erections - and more of them! Tongkat Ali Extract also inhibits globulin, which binds to sex hormones.  By inhibiting this agent, Tongkat Ali assures that more free testosterone remains in the blood. Additionally, this slows the aging process - improving energy and sexual function, helping to reduce body fat, and reducing risk factors associated with cardiovascular disease.  Research: The British Journal of Sports Medicine reported that in a double-blind placebo controlled scientific trial, the use of Tongkat Ali extract caused a 5 % increase in lean body mass in the treatment group. On the other hand, no significant changes were observed in the placebo group. Among other interesting facts, the journal article states: "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."

Previous studies have established that the testosterone supplementation increases fat free mass, muscle strength, and muscle mass, which are important for physical function and athletic performance. Thus, the objective of this study was to investigate the effect of the increase in testosterone levels, obtained by administration of Eurycoma longifolia, 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 Eurycoma longifolia 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) µV (p = 0.012) and from 127.95 (30.9) to 98.8 (50.1) µV (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.

Known as Pasak Bumi in Indonesia , Tongkat Ali in Malaysia , and also as Eurycoma longifolia, its scientific Latin name, the plant grows all over South-east Asia. Dr. Ismail Tambi, who heads the Human Reproduction Specialist Centre at Malaysia 's National Population and Family Development Board, said that 30 healthy males between the ages of 31 and 52 were given two capsules of Tongkat Ali a day for three weeks. They reported that their performances in bed had improved - erections were stronger and, in some cases, lasted longer. Overall, they felt more virile. Their levels of testosterone, the male hormone that plays a significant role in spurring desire and performance, doubled within three weeks. At the same time, the level of globulin, a hormone that inhibits sexual desire,  fell.

School of Pharmaceutical Sciences, University of Science , Malaysia , Minden , Singapore. Study Objective: Aphrodisiac evaluation in non-copulator male rats after chronic administration of Eurycoma longifolia: The aphrodisiac effect of Eurycoma longifolia (0.5 g/kg) was evaluated in non-copulator male rats using an electrical cage. Fractions of E. longifolia decreased the hesitation time of non-copulator male rats, throughout the investigation period. Furthermore, it possessed a transient increase in the percentage of the male rats responding to the right choice, more than 50% of the male rats scored "right choice" after 3 weeks post-treatment and the effect became more prominent after 8 weeks post-treatment (only 40-50% of the control male rats responded to the right choice) using the electrical copulation cage. Hence, this study lends further support to the use of the plant by indigenous populations as a traditional aphrodisiac.

Study objectives: Sexual arousal in sexually sluggish old male rats after oral administration of Eurycoma longifolia: Eurycoma longifolia commonly known as Tongkat Ali in Malaysia , has been used in Malaysia to increase male virility and sexual prowess. The objective of this study is to evaluate sexual arousal in sexually sluggish old male rats, 24 months old and retired breeders, receiving 200, 400, or 800 mg/kg of various fractions of E. longifolia, twice daily, for 10 days. Control rats received 3 ml/kg of normal saline. The aphrodisiac effect was monitored by the act of yawning and stretching because yawning, either alone or associated with stretching, is considered an ancestral vestige surviving throughout evolution that promotes sexual arousal. The results showed that 800 mg/kg of E. longifolia increased yawning by 50% and stretching by 16.7% in sexually sluggish old male rats, by 676-719% and 31-336%, respectively, in sexually active male rats, and by 22-44% and 75-100%, respectively, in middle aged, 9 months old and retired breeders. We conclude that the results of this study support the folk use of this plant as an aphrodisiac.

Research objective: Effects of Eurycoma longifolia on levator ani muscle in both uncastrated and testosterone-stimulated castrated intact male rats: It has been reported that Eurycoma longifolia commonly known as Tongkat Ali has gained notoreity as a symbol of man's ego and strength by the Malaysian men because it increases male virility and sexual prowess during sexual activities. As such, the effects of 200, 400 and 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia were studied on the levator ani muscle in both uncastrated and testosterone-stimulated castrated intact male rats after dosing them for 12 consecutive weeks. Results showed that 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia significantly increased (p<0.05) the levator ani muscle to 58.56+/-1.22, 58.23+/-0.31, 60.21 +/-0.86 and 62.35 +/-0.98 mg/100 g body weight, respectively, when compared with the control (untreated) in the uncastrated intact male rats and 49.23+/-0.82, 52.23+/-0.36, 50.21+/-0.66 and 52.35+/-0.58 mg/100 g body weight, respectively, when compared to control (untreated) in the testosterone-stimulated castrated intact male rats. Hence, the pro-androgenic effect as shown by this study further supported the traditional use of this plant as an aphrodisiac.

The results showed that a high dose (800 mg/kg) of all E. longifolia extracts significantly increased mount frequency (MF) (P < 0.05) over that of untreated controls, but had no effect on the frequency of intromission or ejaculation. Methanol, chloroform, water, and butanol fractions exhibited MF of 2.5 +/- 0.1, 2.6 +/- 0.3, 2.5 +/- 0.1 and 2.6 +/- 0.2, respectively, in adult, middle-aged male rats, and retired breeders versus 2.3 +/- 0.1 in untreated controls. This translated to a minor increase in MF of 8.7%, 13.0%, 8.7%, and 13.0% for these fractions, respectively, during the 20-minute observation period. The results of this study show that Eurycoma longifolia extracts can increase libido in middle-aged male rats. Dr. Simon Chua, Department of Pharmaceutical Sciences, Wayne State University  In a preliminary study at the Reproductive Research Center in Kuala Lumpur , Malaysia , 30 married men, aged 31-52 years old, took Tongkat Ali regularly for three consecutive weeks. Interviews indicated that 48% felt healthy, active and energized, and 40% felt increased sexual desire. The subjects showed an increased free testosterone index. Increased testosterone levels help improve libido, energy and muscle mass for bodybuilding. Their levels of DHEA, another critical steroid hormone, gradually increased from 26% after one week to 47% after three weeks. Most subjects demonstrated increased satisfaction in their sexual health and performance. In addition, animal studies have shown that Tongkat Ali may increase testosterone availability as well as libido in mice.

Dr. James Stoxen (Article Based on a research conducted by his team of doctors) Department of Medicinal Chemistry and Pharmacognosy, University of Illinois, Chicago The production of testosterone (the principal male-determining sex hormone) falls progressively from age 40. Experts call this "partial androgen deficiency of the aging male." Androgens are steroid hormones with specific effects on tissue growth (muscle, fat, skin, hair and others) and brain function. They play important roles in men and women, but are produced in much larger quantities in men. In men after puberty, the testicles produce most androgens, mainly as testosterone. It has been suggested that Tongkat Ali may block negative feedback to the hypo-thalamus and pituitary glands, so the body continues to produce testosterone at elevated levels.

The results showed that E. longifolia produced a dose-dependent, recurrent and significant increase in the episodes of penile reflexes as evidenced by increases in quick flips, long flips and erections of the treated male rats during the 30 min observation period. These results provide further evidence that E. longifolia increases the aphrodisiac potency activity in treated animals.
