Tongkat ali extract cheaters

I have now deviced an easy method on how to unmask the numerous tongkat ali scammers who sell root powder with a claim that it is extract of 1:50, 1:100, and 1:200 strength.

This does not require esoteric tests that measure active ingredients and run into thousands of US dollars at commercial labs.

We are now in the process of just testing the products of suspicious suppliers for cellulose content.

Obviously, root powder has a high content of cellulose, and extract of any strength does not.

Furthermore, in the case of white powders, we test for stearic acid [1] content.

Stearic acid is a fat that is not present at all in tongkat ali root.

Stay tuned for some revealing results. And possibly the involvement of some domestic trade government departments.

What are the active ingredients of Tongkat Ali

A Malaysian producer of tongkat ali extract has heavily promoted their product with claims of a scientific standardization.

As if this were of scientific relevance, they stated that their product is composed of 40% glycosaponins, 22% eurypeptides and 30% polysaccharides.

Judging from the wide circulation of their product, it seems to be easy indeed to fool people by using scientific-sounding terms.

The active components of tongkat ali (Eurycoma longifolia Jack) have of course been scientifically established.

There is an excellent, impartial, not product-oriented scientific source on the Internet:

Unfortunately, the page loads inconsistently. But here a printscreen.

Only the term "polysaccharide" is found on the page, listing the active components of Eurycoma longifolia Jack (tongkat ali), [1] but NOT as an active chemical. A polysaccharide has been used to induce fever in lab animals on which the fever-lowering effect of tongkat ali was tested.

So what are "40% glycosaponins, 22% eurypeptides and 30% polysaccharides"?

Let's start with "eurypeptides" because that was the term I didn't know when I first red the claims made by the Malaysian tongkat ali producer. It was also the term that made me suspicious in the first place.

When you run a general Google search for "eurypeptides", thousands of pages are offered. However, they all seem to refer only to the LJ 100 extract.

You can also try your search on Medline, the huge website of the US National Library of Medicine. The Medline website is:

No "eurypeptides".

It's obvious that "eurypeptides" is a made-up word. Sounds good, though. Reminds of neuropeptides, which indeed have a very important biochemical functions in the human body.

But eurypeptides?

OK, how about glycosaponins? "Glyco-" basically means sugar, and indeed, many chemical substances can be combined with sugars, and they are then referred to as glyco-somethings.

Saponins are found in many plants. The term, however, isn't very specific. Basically, it means that the substance is somehow soapy. If you want to know more about saponins in general, look at this page on Google:

Now, is the Sugar-Soap which the promoters of LJ100 tout as doing the LJ100 magic more real than the eurypeptides?

Try to search on Medline and Google Scholar.

The search results show that the term is only promoted in the context of Malaysian tongkat ali.

And now for the third scientific term that has been used in connection with the marketing of LJ100:

"30% polysaccharides"

You know what polysaccharides are: sugars that are too heavy to be sweet: starch, cellulose, and the like.

If you want to know it more precisely, check this Google link:

If the claim is serious, does it mean that their extract is 30 percent cellulose?

The manufacturers probably realized that the "30% polysaccharides" reference didn't really support their claim to have a superior standardized extract. I didn't see it when I checked their site while writing this article. However, a Google search for LJ100 brings up many marketing sites that still list the "30% polysaccharides".

In spite of, or probably because of, the pseudoscience applied in its marketing, LJ100 today seems to be the most widely distributed tongkat ali product. It's amazing that even a physician with a generally good knowledge of herbal medicines, Ray Sahelian, MD, has fallen for their tricks.

Please note: I do not find anything wrong with genuine tongkat ali. It definitely is the closest, nature has come to develop an aphrodisiac, as well as a supplement to increase muscle mass in men. Both effects have been established in genuine science.

However, the above-described case has added to my doubts on Malaysia as a source country for tongkat ali. Not only is tongkat ali a protected plant in Malaysia, and not only has Malaysian tongkat ali been found to have been contaminated with heavy metals. [2] Malaysian companies have also been on record for spiking tongkat ali with bootleg pharmaceuticals. Compared to that, sales techniques like the one described in this article are still a minor issue.

Eurycomanone - Tongkat Ali's most active component

The scientific consensus is that most of the therapeutic effects of tongkat ali extract ought to be credited to the chemical component eurycomanone. [1] [2]

Eurycomanone is one of dozens of chemical components found in tongkat ali root. Most of these chemical components are similar to each other and classified as quassinoids.  [3] [4]

In Malaysia, where there is very little remaining tongkat ali in forests, it has been tried in a year-long university research program to grow tongkat ali under ideal lab conditions as tissue culture plantlets, with special interests in the yield of eurycomanone.

A slight increase was noted, as summarized in the study abstract:

"... the content of eurycomanone was found to be higher in dried roots of tissue culture plantlets (120.76 ppm/mg) compared with matured root of E. longifolia (101.26 ppm/mg)."

For those not familiar with chemistry lab measurements:

ppm = parts per million

It's a measurement like percent, as which it can easily be written:

101 ppm = 0.01 percent

100 000 - 10.1 ppm

10 000 - 1.01 ppm

1000 - 0.101 ppm

100 - 0.0101 ppm

How Tongkat Ali improves sex

Tongkat ali works. No doubt about that. And in that respect it is in one league with such heavyweights as yohimbine, sildenafil citrate, or cabergoline.

Unfortunately, almost all the tongkat ali on the market in the US is worthless. The effective dose of tongkat ali is about 50 gram of root. Just look at what is sold in US health food stores: 30 capsules of 300 mg root powder. I have to laugh. This is the equivalent of 9 gram of tongkat ali. Swallowing all these capsules in one go will still be underdosed.

If root powder, or chipped roots, were to be used, they would have to be cooked for at least half an hour to release the alkaloids that make for the sexual enhancement qualities of tongkat ali.

But the right way to go anyway is not root powder but an extract. I myself became convinced of tongkat ali's qualities only after I tested the 1:50 extract that has been provided to me (without charge) by the Indonesian company that sells tongkat ali. I have been using 1 gram of their extract on a good number of occasions, and I am now prepared to summarize my experiences.

First of all, what tongkat ali is not. It is not a substitute for sildenafil citrate for most men beyond 50, who typically have weak penile plumbing, like I do. I did try to go without the sildenafil citrate after David reported that he felt so confident on tongkat ali that he no longer needed it, but David may be in better shape. For me, sildenafil citrate is unsurpassed if the task is to assure erection-causing blood supply to the corpora cavernosa of the penis.

But sildenafil citrate by itself is a bore. It causes erections upon tactile stimulation of the penis, but typically, leaves libido trailing far behind.

Usually, older men no longer have great sex for two reasons: weak and leaking penile plumbing (inability to initiate or maintain an erection) and rusty wiring (lack of libido, weak orgasms). To deal with just one of the two aspects won't do if one is after the same quality of sex one enjoyed in younger years.

It has been my long-held opinion that a dual approach is necessary: fix the plumbing (with sildenafil citrate, yohimbine, or alprostadil get), and brush up the wiring.

There are fewer options for the wiring than there are for the plumbing. One is yohimbine, which works on both the plumbing and the wiring, but has a serious side effects downside (heart palpitations, sleeplessness).

Cabergoline and some other dopaminergics work almost exclusively on the wiring. They help on erections only for the short periods of time during which they also make tired and nauseate. Beyond that, they have a definite effect only on libido.  [1]

Cabergoline, more than any other substance, makes men good lovers. It does so by greatly prolonging the time frame for male sexual conduct. On cabergoline, I can easily go on for an hour in one lovemaking session, and the refractory period is comparatively short.

Tongkat ali also shortens the refractory period, but it doesn't make men better lovers.


I have to explain this in pictures.

When I am on cabergoline, I am quite sensitive to the situation. I could never sleep with a prostitute on cabergoline. I'd have my problems with a prostitution setting in an entirely sober condition, too. But on cabergoline, it's even worse. If I don't feel that my female partner is riding on the same wave of sexual excitement, I can lose interest very, very quickly, and in spite of 50 mg of Viagra in my veins, any erection will quickly collapse.

I haven't had any tolerance for prostitution settings for more than 20 years. I often questioned myself how other men could feel any desire or excitement with a woman who (openly) is only after a payment.

Well, after ingesting 1 gram of tongkat ali extract, I get the idea. Sex on tongkat ali is much more direct than in any other condition. Actually, on tongkat ali, my sexual encounters are of a style as they were when I was in my late teens (!).

At the age of 18 / 19, I, with a group of friends, every Saturday evening went girl hunting. This was in provincial Germany in the early 70s. I didn't care much, nor did my friends, whether our prey was beautiful, or even whether they were genuinely interested in sex. We just took whatever girls were willing to come along, beautiful or ugly. Anyway, if the one you got was ugly, you could always turn off the light.

And if she wasn't really willing from the start, you could always try to talk her into at least a hand job. "Touch me here, just for a moment." or "Just let me put my hand inside your blouse for a moment."

Or one would try to squeeze one's hand in between her legs (which she closed with all strength available to her). It often was an odd situation. On the one hand, the girls did feel sexual pleasure (as could be told from their vaginal wetness), but they didn't want to give up resistance (in order to protect their reputation, or because it was a principle never to go beyond kissing on a first date).

Never mind. Ugly or beautiful. Wet or dry. For me, it was always good sex (even if for her it wasn't really sex at all).

It wasn't like that anymore some ten years later, and until I went on the tongkat ali trial.

Sex under the influence of tongkat ali feels more direct (and can I say: more masculine?) than it has any time since my late teens. And it is this directness, which more than anything else typifies tongkat ali.

Is this because of raised testosterone levels? Sounds like it, but the jury on testosterone levels is still out (as of this writing, our tongkat ali trial is still ongoing).

For me, sex is much shorter on tongkat ali than it is on cabergoline or any other dopaminergic. [2] Which doesn't mean that I wouldn't get exited. I surely do.

Tongkat ali, for me, also has an effect on erections, though not as a facilitator in principle (for that, I use sildenafil citrate). But tongkat ali makes erections tenser.

Not only erections but also the whole body. On tongkat ali, I often feel inclined to clinch my teeth. I also develop a tendency for subduing gestures towards women. And I hold them with a much firmer grip.

After taking my dose of tongkat ali, I am more prone to develop fantasies of punishing women than I would be in a sober state. And yes, penetration can be as forceful as if I were to rape my partner.

No, the tongkat ali won't turn me into a real rapist. I have enough control over myself to avoid getting into this kind of trouble. But sexual encounters always happen on two levels, the actual and the imaginative one. And on the imaginative level, tongkat ali makes sex more violent.

What else?

Better ejaculatory power, multiple orgasms, and feeling very male.

Better sex, more muscle

Better sex, more muscle... this is what tongkat ali can do for you. Provided you buy it from a legitimate source that doesn't sell you an outright fake or grossly under-dosed product.

To avoid being cheated by an online con artist selling fake tongkat ali extract, just do a Google search for: tongkat ali scam. You may also want to avoid a product that uses stearic acid or stearates. To be sure, just do a Google search: tongkat ali stearic.

And then, better take an Indonesian product, as a large number of Malaysian ones have been shown to be contaminated with mercury and other heavy metals. Again, just google: tongkat ali heavy metals

If you buy a Indonesian product, just make sure it is not connected to the indonesiaherbals scam that has been widely reported in Indonesian newspapers.

While men in Southeast Asia have traditionally been using tongkat ali to increase their virility, women in Southeast Asia have always relied on kacip fatima to keep pace with their men. On the other hand, women who want a stronger effect can also use tongkat ali, typically at half the male dosage.

Without doubt, in Southeast Asia love and sex are regarded as natural pleasure (for men and women) much more clearly, and more directly, than in Europe or North America. Here you still have matrilinear societies (such as the Minang on Sumatra), a kind of Islam (on Java) that encourages pre-marital love (though "officially" not pre-marital sex), societies where sexual relationships of older men and older women with much younger partners are socially accepted, and where sexual details until now are openly discussed in villages.

While both tongkat ali and kacip fatima both raise free testosterone, tongkat ali is the stronger of the two.

Men and women in Southeast Asia have long regarded it as an art and a science to improve their sexual function, or to bring it back to youthful levels when there has been an age-related decline.

Asians use many herbs for their sexual effects, and even herbs with rather distinct efficacies are traded openly. In Indonesia, for example, herbal mixtures such as "Galian Rapat" are sold at many cigarette booths. The name means "narrow cavity", or, more specifically, "narrow vagina", a condition considered conducive to sexual pleasure. A common ingredient is kacip fatima. [1] Other are sirih leaves. [2]

Whether the female primary sexual organ is in an optimal condition after the consumption of kacip fatima, and whether women experience heightened sexual pleasure by using the herbal (as they have done for hundreds of years) is a matter sufficiently important to the Malaysian government to finance interdisciplinary scientific research into kacip fatima. And the Malaysian government has a stake in the medical, pro-sexual use of tongkat ali for men as well.

As a long-term user of tongkat ali, I have considerable trust in Southeast Asian herbal medications. Even though kacip fatima is considered primarily a herb for women, and even though I am a man, I have tried it a few times and can attest to the herb's pro-libido effects. The effect of a few leaves, boiled as a tea, is a mixture of sympathetic and parasympathetic stimuli, with the parasympathetic effects being dominant. Among the parasympathetic effects are nasal sinus stimulation resulting in a stuffed nose, as I also feel it from dopaminergic medications, and yes, increased blood flow to the groin. The primary sympathetic effect is a slightly increased heart rate.

Tongkat Ali and stearic acid

I write about stearic acid only because it is contained in some tongkat ali supplements, mostly those sold in so-called healthfood stores.

Refined stearic acid is a chemical substance typically derived industrially from low-quality animal fat.

What is low-quality animal fat?

You guessed it. Animal carcasses, fat refuse from factories that produce processed meats (mostly of pork origin).

You can read about stearic acids on the "Chemical of the day" site. To get there, do a Google search on:

Chemical of the day - stearic acid

You can also go to the page directly through this link:

This is not appetizing, is it?

But it gets worse.

Try a Google search on:

list of widely known dangerous ingredients in body & food products - stearic acid

If you are still not yet convinced that you should avoid tongkat ali products from sources that utilize stearic acid to extend shelve life or make their material easier to handle, consider this:

The industrial stearic acid is processed from animal fat. Many of the animals, the carcasses and internal organs of which are used in the stearic acid manufacture, have been exposed to chemical and / or hormonal contamination. A large number of these contaminants are endocrine disruptors in humans.

Contaminants [1] that are endocrine disruptors build up mostly in the fatty tissue of animals (see Wikipedia on endocrine disruptors).

Now remember that industrial stearic acid is manufactured from the fatty tissue of animal that were poisoned, or died of diseases, or the fatty tissue of discarded animal parts.

Consider also that often, the concentration of chemical contaminants is higher in the results of industrial processes than in the raw products used.

Fuck it!

Isn't it cynical that some manufacturers stretch tongkat ali, a testosterone-raising hormone modulator, with an industrial chemical that can be reasonably suspected to be a hormonal disruptor?
