Whilst the mechanism by which it raises testosterone levels isn't definitively known, it is thought that Tongkat Ali inhibits the aromatase enzyme and simultaneously raises LH levels and total testosterone concentrations. Most natural testosterone enhancers only work via one of these mechanisms.
Users report no negative endocrine feedback after using tongkat ali for a period of time – testosterone levels remain unusually high for as long as you use the supplement.
This means that embarrassing and annoying side effects of Testosterone Replacement Therapy, such as testicular shrinkage, will not occur when using tongkat ali for raising testosterone levels.
Instead of testicular shrinkage, when you try tongkat ali you will find your testicles become much fuller, heavier and bigger - this is testiment to tongkat ali improving sperm production.
I’m sure you’re fully aware of the benefits of having a high testosterone level – high testosterone means more muscle mass, less body-fat, higher energy levels, more confidence, a higher sex drive and better sex (and a bit more aggression). Simply put, testosterone makes a man, ‘the man’!
But taking supplements for raising testosterone levels isn’t all about vanity – low testosterone has been repeatedly shown to be a factor behind diseases such as diabetes, osteoporosis, depression and more.
Luckily, with a good diet and lifestyle, by taking this effective supplement we can now maintain a high testosterone level right up into old age.
Whilst it’s clear that men with low or mid range testosterone levels need to get their levels up into the high range, it’s not as simple as taking a testosterone pill or using a testosterone gel every day. There are many, many problems associated with Testosterone Replacement Therapy (TRT).
The most obvious problem is one that I wouldn’t wish on my worst enemy, TESTICULAR ATROPHY! TRT causes your penis and testes to shrink!
This is because, when you add testosterone exogenously (externally), your own testes receive the signal that they no longer need to produce their own testosterone and subsequently your prized member begins to shrivel down in size.
Other issues caused by using synthetic TRT for raising testosterone levels listed by the Mayo Clinic are:
These issues with TRT are why bodybuilders, strength athletes and many guys are always interested in raising their testosterone levels by using natural supplements.
This study also found a significant androgenic effect when tongkat ali was administered to castrated rats and these rats become considerably more sexually orientated than controls!

(The above list of positive studies examining tongkat ali’s effectiveness at raising testosterone levels in rodents is by no means exclusive).
Impressive human studies!
In the below human studies, tongkat ali allowed men to build muscle mass whilst simultaneously losing body fat, without changing their diets. Tongkat ali, taken daily, also improved subjects’ energy levels and mood. These are all effects of having a higher testosterone level.
The Malaysian studies in this list used a tongkat ali product called LJ100 (standing for Long Jack 100) which is 1:100 strength. Even greater increases in testosterone would almost definitely have occurred had the researchers given the subjects one or two 600mg capsules of 1:200 strength tongkat ali extract, as I recommend.
Study 1: Tongkat ali improves male fertility:
The following well designed study showed that tongkat ali significantly improves male fertility:
Eurycoma longifolia Jack in managing idiopathic male infertility.
Asian J Androl. 2010 March. Bin Mohd Tambi MI, Imran MK. Wellmen Clinic, Damai Service Hospital, Kuala Lumpur 52100, Malaysia. Department of Community Medicine, School of Medical Sciences, University Sains Malaysia, Kbg Kerian, Kelantan 16150, Malaysia.
'We investigated the effect of treatment with the proprietary standardized, water-soluble extract of the root of the Malaysian plant, Eurycoma longifolia Jack, which is thought to enhance male fertility with regard to higher semen volumes, sperm concentrations, the percentage of normal sperm morphology and sperm motility in male partners of sub-fertile couples with idiopathic infertility.
A total of 350 patients were given 200 mg of the extract daily and follow-up semen analyses were performed every 3 months for 9 months. Of these 350 patients, 75 patients completed one full cycle of 3 months. Follow-up semen analyses in these patients showed significant improvement in all semen parameters. The proprietary extract of Eurycoma longifolia Jack significantly improved the sperm quality in these patients, allowing for 11 (14%) spontaneous pregnancies.'

Study 2: Tongkat ali for raising testosterone levels!
University of Malaysia, Dr. Ismail Tambe - UnPublished
Saliva Testosterone Test After Taking 1:100 strength tongkat ali:
• Saliva Testosterone Test of 9 Individuals 26-52 years of Age
• Dosage 2x2(50mg/capsules) morning & evening for 10 days
• Normal range for athlete 800 = 150ng/dl of blood
Data – preliminary data - more work to be carried out
Volunteers 1-5 are athletes - data are an average of 3 different studies at different times
Volunteers 6-9 do not exercise on a regular basis
My comments:
Major increases in testosterone occurred in all volunteers in these two studies regardless of their starting testosterone level.
It is not fully understood why, but it is known that it is until your total testosterone level is significantly elevated that muscle mass gains become really pronounced.
Products that improve free testosterone levels but do not elevate total testosterone levels generally make men feel better, improve their sex drive etc., but do not stimulate significant extra muscle mass growth.
Tongkat ali raises both total and free testosterone levels – this explains why tongkat ali combined with weights training allows for pretty dramatic muscle mass gains and also why it improves most men’s libido, sexual performance and mood.

Study 3 – Tongkat ali increases arm circumference and strength!________________________________________
University of Malaysia, Dr. Ismail Tambe - UnPublished
'Testosterone is renown biochemically for its muscle building nature and net effect of increasing metabolic rate and enhancing the process of biosynthesis.
In this study, seven male subjects aged between 26-32 years took 100mg of LJ100 for a period of 8 weeks. Simultaneously, subjects performed an intensive strength training program with initial load of 60% RM, which was carried out on alternate days. Measurement of skin fold thickness, arm circumference, one repetition maximum (1RM) strength on the upper limb and the electormyographic activity of biceps were recorded before and after the period of consumption of LJ100. A double blind study of 7 controls were conducted.'
Results:
% Fat Before: 31.3 % Fat After: 28.4 Arm Circumference Before: 30.9 Arm Circumference After: 32.7 1RM Muscle Strength Test Before: 73.7 1RM Muscle Strength Test After: 78.7
The mean frequency of sEMG on bicep muscle contraction of the subjects showed a more significant improvement in strength (p<0.05) compared with the controls (p>0.05).
My comments:
Great arm size and strength improvements from taking tongkat ali. We all want bigger biceps!
Study 4: Tongkat ali increases fat free body mass!
'Fat free mass of the group supplemented with LJ100 Eurycoma water soluble extract showed a significant increment of approximately 2.1 kg. There were no significant changes in fat free mass in placebo. Body fat percentage were significantly decreased in treatment and placebo. However, a greater decrement was shown in treatment compared to placebo i.e. 9.14% and 6.57% respectively.
The 1 RM test muscle strength test showed an increase in gross muscle power in both groups. The treatment group showed a greater increment in strength compared to placebo i.e. 6.78% and 2.77% respectively.
The mean arm circumference in treatment group increased significantly by 1.8 cm following the supplementation while no significant changes observed in placebo group. The mean sEMG reading of the treatment and placebo showed a significant decrement in values after going through the exercise program. However, the treatment group showed 2.92% higher reduction in electrical activity of the muscle measured at the end of the experiment period compared to placebo (25.70% and 22.78% respectively).
During and after the administration of Eurycoma, no adverse effects were noted within the treatment group.'
My comments:
This study demonsrates that, by raising testosterone levels, tongkat ali simultaneously improves muscle mass whilst reducing body fat.
This is why testosterone lowering fat-loss diets that restrict dietary carbohydrate and fat but greatly increase fiber and protein are not good for long term fat loss and in fact worsen body composition and strength levels.
People looking to make long term body composition improvements should avoid crash diets and should instead aim to improve their hormone balance to allow them to build more muscle mass.
Study 5: Tongkat ali improves sex drive and performance in aging men!
M.I.M. TAMBI, S. OTHMAN AND J.M. SAAD
'SHIQ results showed 62% of the cases having an increased or maximum score. Breakdown of the results showed increase in sexual desire and success in the attempts at sexual intercourse while on treatment and related well with the PADAM score’s results showing improvement in sexual attempts and desire.
PADAM score demonstrated that 82% of the cases showed a decrease in total score. The breakdown included: 91% improvement of sexual component, 73% improvement in the physical component, and 82% improvement of the psychological component. The Vasomotor score showed improvement in 52% of the subjects.
Analysis of DHEA showed gradual increase in the level from 26% after 1 week to 47% after 3 weeks. This suggests that the extract may influence the DHEA production, which would in turn subsequently be aromatized to testosterone.
SHBG analysis showed that levels were reduced in 36% of the cases after one week. The reduction went up to 66% after 3 weeks. This suggests that the extract could have an effect on the production of SHBG. Consequently, when SHBG level declines, the Free Testosterone Index (FTI) goes up. FTI analysis showed an escalation of 39% of subjects after 1 week and 73% after 3 weeks.'

Study 6: Tongkat ali improves sexual desire and performance whilst improving numerous health parameters!
2005 HUMAN CLINICAL
'20 male volunteers of various health conditions from the ages of 38 to 58 were randomly given either 200,400,600 mg of LJ100 (22% Bioactive Eurypeptides) or placebo for 2 months. The SHIM (Sexual Health Inventory for Male) scores were elevated to upper normal level showing improvement in sexual desire and performance for majority of the volunteers.
The Aging Male Score (AMS) were lowered showing improvement in sexual, physical, psychology, and vasomotor domain for majority of the volunteers. Testosterone and DHEAS levels showed high normal levels when compared to baseline and is consistent with the excellent QOL (Quality of Life) score. LJ100 modulates the production of DHEAS, which would in turn be aromatized to testosterone. Bioavailable testosterone is needed to maintain wellness and enhance libido.
Full blood examinations showed normal limits even at 600mg dosage for all tests. LJ100 does not interfere with the platelets or hemoglobin and does not have any toxicity to the RBC. The liver function test showed no liver toxicity even at high doses of LJ100 . Renal function test showed that LJ100 has no harmful effect on the renal system even for men whose renal function is affected (as seen in the diabetics).
Some volunteers even showed improved or normal levels of uric acid at end of trials. Tumor markers are sensitive indicators of cellular stress. AFP( Alpha Fetal Protein) identifies testicular cancer; PSA ( Prostate Specific Antigen) is used to detect prostate cancer. All tumor markers were within normal levels even at 600mg dosage of LJ100 .
The Lipid studies showed increment of high-density lipoprotein (HDL Cholesterol –good cholesterol) levels. Elevations of HDL are normally associated with a lower risk of heart attack.
Volunteers who were diabetic, showed significant effect on lowering the blood glucose levels. LJ100 does not exert hypoglycemic effects but may have influence on the cellular uptake of glucose.The cortisol levels were in the higher normal level for the LJ100 group as opposed to the placebo group.
High thyroxin indicates high BMR (Basal Body Metabolism Rate). Majority of volunteers on LJ100 have high normal level of thyroxine compared to the placebo group. This mean slight higher metabolism rate which can be translated to better weight management.
Volunteers taking LJ100 have high normal level of IGF-1 at end of trials. Some with low IGF-1 level was increased to normal level after 1 week. Placebo group is showing no change in the IGF-1 levels. This study suggests that LJ100 has a secretagogue effect on growth hormone and modulates the release of IGF-1; in turn, making it a great anti-aging supplement.'
My comments:
This study clearly demonstrates how important it is to maintain high testosterone levels for your overall level of health.
In this study, improved testosterone caused reductions in blood sugar levels, improvements in HDL cholesterol and increased thyroid function leading to a higher metabolic rate!
The link between low testosterone and low thyroid function is one that is being more closely examined by doctors currently. Men treated with thyroid hormone replacement may achieve improved lab values but the root cause of their low metabolism could be low testosterone levels.
Many of these men would feel and look better if they treated their low testosterone by regularly using tongkat ali rather than taking extra thyroid hormone.
STUDY 6: Tongkat ali maitains high testosterone and keeps cortisol low during intense aerobic training
• Talbott S, Talbott J, Negrete J, Jones M, Nichols M, and Roza J.

• Published: Journal of International Society of Sport Medicine 3 (1): S32 2006
'Eurycoma Longifolia, commonly known as "Tongkat Ali" or "Longjack", is often touted as a testosterone "booster" and marketed to athletes as a training aid and performance enhancer.
Rodent studies have shown oral delivery of Eurycoma extract to improve sexual performance and increase serum testosterone levels.
Open-label human trials have suggested that Eurycoma extract may help prevent age-associated androgen defieciency, improve sexual function, and increase psychological parameters such as mood, energy, and sense of well-being. The purpose of this study was to determine the effects of Eurycoma Longiflia on testosterone and cortisol levels during intense endurance exercise.'
METHODS
'We used a freeze dried extract of Eurycoma Longifolia (E) standardized to 22% EuryPeptides and 40% Glycosaponins. Male subjects (N=30) were recruited from a 24-hour mountain biking event and asked to provide a saliva sample before and after each lap for measurement of cortisol and testosterone by enzyme immunoassay (Salimetrics, State College, PA.) Subjects completed 4 laps (14.91 miles / lap) and provided 8 saliva samples over a 24 hour period. Subjects consumed 100mg of E (N = 15) or a look-alike placebo (P, N = 15) approximately 30 minutes prior to exercise.'
RESULTS:
'Cortisol levels were 32.3% lower in E compared to P (0.552+0.665 versus 0.816+0.775 ug/dL, P < 0.05). Testosterone levels were 16.4% higher in E compared to P (86.72+40.90 versus 72.47+33.77 pg/mL, P < 0.05). '
CONCLUSIONS
'These results suggest that Eurycoma Longifolia extract may help to maintain normal levels of cortisol (low) and testosterone (high) and thus promote an overall "muscle building" hormonal state (versus a "catabolic" state characterized by elevated cortisol and suppressed testosterone) during intense endurance exercise.'
My comments:
One of the disadvantages of aerobic training is that it can decrease testosterone levels and raise cortisol. This is why I generally recommend people focus on weights training as this form of training is effective for naturally raising testosterone levels, as long as you don’t overtrain.
Sensible aerobic training can, however, benefit both dieters and strength athletes if it is not done to an extent where it begins to worsen hormone balance. Tongkat ali appears to keep testosterone from dropping during intense aerobic exercise, thus negating one of the major negative effects of this form of training.

Real Life Results from taking tongkat ali
Users of properly formulated tongkat ali products are finding that their testosterone levels are doubling in as little as two months! With none of the side effects of T.R.T. such as testicular shrinkage and gynecomastia!
This is a completely different situation than with the old bodybuilder’s favourite, Tribulus Terrestris. This herb, marketed as a testosterone enhancer, fools many users into believing that it is working due to its aphrodisiac and mood boosting effects but numerous studies show that it is inneffective for raising testosterone levels.
Testimonials
Below are recent testimonials from first time tongkat ali users:
'I have been taking Tongkat Ali now for nearly six weeks, on a 6 days on, 3 days off cycle. I have noticed several positive developments over the period, especially over the last two weeks or so.
First, I would say that, overall, I have experienced an enhanced sense of wellbeing. My general energy levels have been higher than normal. More specifically, I have increased the weights for all gym exercises, which is encouraging as I felt I had rather plateaued at previous levels. My recovery time between sessions also seems to have improved. The rate at which I am reducing fat and increasing muscle and muscle definition has certainly accelerated.
Apart from taking Tongkat Ali, I have made no other significant changes to diet or lifestyle during this time. It therefore seems to me that most of the effects must be attributed to this herbal supplement (although my increased energy and shorter recovery time has encouraged me to fit in a few more exercise sessions than before, which obviously does itself improve mood and further accelerate results).
I have also experienced increased libido. If Tongkat Ali does increase testosterone, that would account for many of the positive effects. In the meantime, I have suffered absolutely no adverse side effects. I certainly intend to continue taking Tongkat Ali for the foreseeable future,
Thanks very much for introducing me to this substance.'
From Simon, London, 01.02.2011
‘Hi Ed,
Well just a little info about me. Me and my wife have been together for 41 years and still have sex at least twice a week. I am 55 and she is 57. I do take a few herbs in a formula that contains Horny Goat Weed, Tribulus Terrestris, Ginseng, Yohimbine etc. They do seem to give me a lift.
I also just started taking maca about 3 weeks ago and took your advice and cut back to just one level teaspoon. It’s a bag of organic.
So I took 2 (tongkat ali capsules) on Sunday and 2 on Saturday. And took your advice and started with just 1 on Monday and one yesterday (when emaiiled I recommended he began with 1 per day).
Well me and the wife decided to have a couple of cocktails and then 1 thing led to another you know what I mean! It was really after just 4 days unbelievable, and I don’t mean my workout at the gym. I can’t wait for our next wrestling match this Saturday. I’ll keep you updated.’

What you can reasonably expect from taking tongkat ali
Users of a high quality tongkat ali product, at the correct dosage, can realistically expect to achieve testosterone level improvements similar to those they would achieve from T.R.T. – but without classic, undesirable side effects such as penile shrinkage.
If you have normal testosterone levels you can expect tongkat ali to push your levels right up to the top of the natural range and to keep you there.
With a high testosterone level you can expect to see improvements in mood, increased muscle mass, modest reductions in body-fat and improved sexual function and sex drive –without training.
Combined with intelligent weights training, you can expect to significantly increase your muscle mass and reduce your body fat by taking tongkat ali due to it naturally raising testosterone levels.
This is because with a higher testosterone level you will be able to lift heavier weights and train more frequently without overtraining as your muscle recovery will be improved.

Cycling tongkat ali:
There are a hell of a lot of worthless products out there for naturally raising testosterone levels, but tongkat ali is the real deal.
I recommend buying 60 capsules – this will last you six and a half weeks if you take 2 capsules per day and cycle it 6 days on, 3 days off.
Taking tongkat ali every day will not lead to it becoming ineffective but cycling tongkat ali is the most effective way to use it.
I would recommend you consider trying out a weights training program, based aroung heavy compound movements such as the squat, deadlift, bent over row and bench press, to complete over this period. The combination of tongakt ali and weights training will be greatly improved muscle mass, strength and fat loss.
Weights training, as long as you do not consistently ovetrain, is great for raising testosterone levels and lowering cortisol. Heavy weights training whilst taking tongkat ali will make you feel and look great!
60 day 100 percent money back guarantee!
If after trying tongkat ali for six and a half weeks you are in any way unsatisfied with the product just send the containers, however unused they are, back to me and I will completely refund your purchase!
