  • Now 650mg capsules! Barlowe's Herbal Elixirs is offering a quality Tongkat Ali (Longjack) 100:1 Extract at a very reasonable price. This is a water/alcohol extract of high quality, and Barlowe's is able to sell this powerful product at such a low price because it is produced from cultivated Indonesian Tongkat Ali roots which are then processed and extracted in China.  The  Tongkat Ali Certificate of Analysis (COA) for this particular batch is shown above. This product is primarily utilized as an aphrodisiac and as a treatment for erectile dysfunction. However, since it increases testosterone levels, it is a great tonic for youthfulness as well. Since this product raises free testosterone levels in the blood, it is a good idea to take High Potency Nettle Root Extract with it, as a substance in 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 (Vegan, Kosher and Halal certified) are filled on slow speed equipment and only pure, unadulterated herbal extract is contained in the capsules. There are no magnesium stearates, fillers, gelatin, silicates, gluten, corn, wheat, rice, yeast, starch, titanium dioxide, artificial colors, artificial flavors or preservatives. Capsules produced with high speed equipment in herbal and dietary supplement "factories" generally contain several other ingredients, including powdered lubricants called STEARATES (which can greatly diminish an herb or supplement's absorption into the body). Check their labels! Barlowe also bottles his products in glass as he believes chemical vapors can vent from plastic containers and contaminate the contents and that glass is 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. 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. 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 100:1 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.


    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."

    Eurycoma longifolia, 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 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. Source: Abstract is taken from the website of British Journal of Sports Medicine.

    Preliminary tests show that Tongkat Ali, an herbal aphrodisiac made from the root of a plant known by the same name, can add to a man's libido and sexual prowess. 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. Source: The Singapore Straits Times, Feb 2003

    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. PMID: 11564133 [PubMed - indexed for MEDLINE]

    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. PMID: 15803965 [PubMed - indexed for MEDLINE ]

    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. PMID: 11693547 [PubMed - indexed for MEDLINE]

    Study Objective: Effect of Eurycoma longifolia on libido in middle-aged male rats: The effect of increasing doses of various fractions of Eurycoma longifolia extracts on libido was examined in middle-aged male rats. 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.

    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.

    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 butanol, methanol, water and chloroform extracts of the roots of Eurycoma longifolia Jack were studied using various tests of potency of treated male rats. 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.

    I just received my new T scores: (8/7/17) Total T last month was 283, NOW: 370 !!! Free T last month was 4.2NOW: 5.5 !!!
    Thank you so much for the help you have given to me - don't stop now!!!! S.C., Gaffney, South Carolina (08/06/2017)

    Recently purchased a couple bottles of Tongkat Ali from you to go along with my re-intro to working out and can say I'm thoroughly impressed once again with your products. Z.S., New York, New York (04/06/2017)

    Hi Barlowe, I am a regular user of your Tongkat Ali. It raised my low testosterone by 40% when I first started using it! R.R., Tacoma Park, Maryland (11/21/2016)

    I got the order of Kanna and Tongkat within 6 days which is really fast shipping to Canada. Thank you very much. I also like to thank you for the sample pack. I ripped the ligaments and tissue of my T12 vertebrae eight years ago. When it first happen I started using pain killers. From there I went to herbs - Kratom and Kava - but it was getting expensive. On a website I saw one person report how much relief he got from joint pain using longjack ali. So I ordered some and tried it. Within a week I wasn't in pain. In the last two weeks my back flared back up. I was taking 20 Tylenol with codeine so I wouldn't be crying at work. Monday morning the Tongkat I ordered from you arrived. Today is Wednesday and I woke up without pain and throughout the whole day I have only taken two Tylenol with codeine to numb the pain a bit. You sell some of the best Tongkat I have ever tried. I hope you share this with people because I know all about severe chronic back pain and no one needs to go through it. Thanks Barlowe. K.F., Ontario, Canada

    Hey Barlowe, hope you're doing well. I just wanted to tell you that I am overly impressed with your 100:1 tongkat. It seems to be extremely potent. I'm taking 4 a day and have noticed the effects after only three days.  I have noticed more energy and my libido is through the roof.  I'll keep you informed on future results but I just wanted to let you know how pleased I am so far. Thanks for everything! J.L., Hazlehurst, GA (5/27/2013)

    Hi- I'm S. C., a 58 year-old bodybuilder. I bought about 16 of your products a while back. These things have really kicked in, and made a noticeable difference in my testosterone state. I am losing fat while gaining muscles, with the most productive weight lifting sessions I have had since I started 3 years ago. I just wanted to let you know. S.C. Apple Valley, MN (6/04/2013)

    Your Tongkat Ali (100:1) is dynamite, best I've tried, works well before a weight workout. Thanks. D.S. Upland, CA (10/04/2013)

    Having tried a few testosterone supplements on the market I feel I’m qualified enough to give a product review and recommendation. Also I’m forty net year and therefore old enough to get some benefit from the products. Your fenugreek supplement is the best natural testosterone boosting supplement available. The increase is greater than that of D Aspartic acid and sustained for a much longer period of time. It’s so effective I’d almost insist it’s taken in conjunction with an estrogenic inhibitor. I would challenge anyone to have blood test against an alternative supplement that could rival it. Your tongkat ali extract (100:1) is a strong second. The testosterone rise is not as large but it’s aphrodisiac and male performance qualities are superior to any product on the market. B.P., Victoria Point, Australia (11/06/2014)

    Caution: This herbal extract is generally safe, but it is potent and should be utilized with care. This product is for dietary use. If unexpected side-effects occur, discontinue use immediately! Since Tongkat Ali increases testosterone levels, it should not be used by men with prostate cancer. The above statements have not been evaluated by the Food and Drug Administration (FDA). This product is not intended to diagnose, treat, cure, or prevent any disease.

    Directions For Use: Take at least two capsules daily. This product has to be taken daily as it requires time for testosterone levels to build up in the blood. Tongkat Ali 100:1 Extract usage should be cycled on a two to one basis for best results. For example, take the product for two weeks, then cease use for a week before again using the product for two weeks (may also do 4 weeks on, two weeks off). Some people may need to increase dosage as results and usage amounts vary based on body type, age and weight. You should start experiencing benefits from Tongkat Ali within two weeks.
