Tongkatali.org - Durian for superior health

By Serge Kreutz

Durians are the best tasting and most healthy food on earth.

It's as simple as this.

Durians have the most balanced nutritional profile of any fruit or plant. Apart from the vitamins found in any other fruit, too, such as vitamin C, durians also pack the full range of B vitamins which usually are associated with animal-derived diets only.

Thus, durians are almost a must for vegetarians, especially if they are sexually active.

Of course, durians are nutritious. Any human could live for decades on just one durian a day.

Yes, durians contain more fat than the average fruit. But there is no cholesterol. Actually, cholesterol is a fat only present in animal sources of nutrition, never in any plant.

But the fats in durian are monounsaturated. That is the healthiest fat you could possibly eat. It protects against heart attacks and strokes.

And then: every gram of durian releases more antioxidants than a gram of any other fruit, and, for that matter, a gram of any other food. Thus, durian has the power to help in life extension.

The only crux with durians is that they aren't available everywhere, and even where they are available, the availability is highly seasonal. This is why Sumatra Pasak Bumi, an Indonesian company active throughout Southeast Asia has come up with a product they call durian flakes. Durian flakes are raisin-sized bits of desiccated durian flesh which can be stored for many months, and shipped throughout the world.

Powerful testosterone boosters can have profound effects on some individuals

Tongkat ali and butea superba are both testosterone boosters. As such they also elevate dopamine, an important brain neurotransmitter.

On some people, such substances can have profound effects, and some people may even be allergic.

I myself sell the tongkat ali and butea superba extracts of Sumatra Pasak Bumi (tongkatali.org). They have an excellent safety record, with no known major adverse event. If it would be different, I would not sell them.

Nevertheless, I can only advise people to be careful. Of any supplement you buy, professional conventional wisdom is that you take a minimal dosage first as an allergy test.

A minimal dosage could be a quarter of a tablet of which you are advised to take two twice a day.

Allergic reactions are unpredictable, especially for plant extracts, or, more scientifically, phytochemicals.

I know people who are allergic to bananas, and I know people who are allergic to sauerkraut, and people who are allergic to citrus food.

A classic allergic reaction is fast. It often involves the release of histamine, which causes visible symptoms like a runny nose or watery eyes. But a wide array of other fast reactions is possible.

Many pharmaceuticals cause allergic reactions, and the same tendency exists for natural phytochemicals. Be smart... do an allergy test with about as little a quantity as a pinch of salt that you would sprinkle over a fried egg. If you are allergic in a classical sense, you will feel it quickly. And if you are not allergic, simply nothing will happen.

A profound reaction is different from an allergic reaction. Some medications and botanicals are tolerated well by some people, and have extreme effects on others. That's how different we all are.

I myself tolerate tongkat ali and butea superba well. I have a very low tolerance for yohimbe. Even a quarter of a single yohimbe capsule causes me a worrisome tachycardia, and I will not be able to sleep for more than 30 hours after ingesting such a small dosage of yohimbe. But two of my friends sleep just normal after more than double standard dosages (4 yohimbe capsules). They can take ten times more than me, and are not punished with any ill effects.

I do not sell yohimbe. I just sell tongkat ali, butea superba, and kaempferia parviflora, all manufactured by Sumatra Pasak Bumi. My prices are lower than those of tongkatali.org, but what really sets me apart is that I give you cautionary advice.

Clinical Trial - Testosterone Levels after the Consumption of 1:200 Tongkat Ali Extract from Indonesia

If the testosterone levels of adolescent malesare raised with potent 1:200 Tongkat Ali Extract from Indonesia, this can be dangerous for human communities. Younger men may find it hard to manage extraordinary sexual agitation, especially after larger dosages like those for older men. Therefore, the minimum age of male trial participants should be 25 years. There is no age limit for female trial participants.

Trial participants should not have been using genuine Tongkat Ali products for at least one year. Before trial participants start to consume 1:200 Tongkat Ali Extract from Indonesia, they should have their blood tested for testosterone A (bound to Sex Hormone Binding Globulin) and for testosterone B (not bound to Sex Hormone Binding Globuline).

Test results should be sent as email attachments to Tongkatali.org.

Low testosterone levels is an underestimated modern scourge. Low testosterone levels cause infertility of men, and disturbe sexual desire and sexual function. Low testosterone levels causes depression and a general feeling that life is not worth living. High testosterone makes optimistic. Men with high testosterone levels have an athletic shape of the body. High testosterone also creates an aura that makes men of any age look attractive to women. Men with high testosterone are often more successful in their professions. Testosterone makes intelligent and boosts the immune system.

But testosterone injections, testosterone capsules, and testosterone patches are not the solution. Many of the positive effects of testosterone are not linked to the presence of testosterone in blood plasma. Many positive effects of testosterone are linked to the fact that the body synthesizes testosterone.

In men, most testosterone is synthesized in the testes. But testosterone is also synthesized in adrenal glands and in various cell clusters along the axis of the hypothalamus, the pituitary gland, and the gonads. Along the axis of the hypothalamus, the pituitary gland, and the gonads, testosterone interacts with other hormones and with neurotransmitters like dopamine. Sexual phantasies and sexual satisfaction are related to the intereaction of the synthesis of both testosterone and dopamine in the preoptic area of the hypothalamus. A lack of sexual excitement and sexual satisfaction resulting from a hypothalamus that is out of tune cannot be medicated with testosterone injections, testosterone capsules, or testosterone patches.

Testosterone injections, testosterone capsules, and testosterone patches are effective in sports doping and bodybuilding. But for sexual parameters, all three will cause more harm than benefit.

1:200 Tongkat Ali Extract from Indonesia stimulates the whole axis of the hypothalamus, the pituitary gland, and the gonads. The stimulaton not only causes the sythesis of testosterone, but also of luteinizing hormone, follicle-stimulating hormone, and many other hormones. The syntesis of the neurotransmitter dopamine is also enhanced.

Trial participants are encouraged to keep a diary and write down episodes of sexual agitation. They could be discussed with the trial coordinator. Sexual fantasies are the clearest indication of an activated axis of the hypothalamus, the pituitary gland, and the testes. Participants should be aware that Tongkat Ali is not a medication for blood vessels. Erections of the penis are caused by changes in blood vessels, not hormonal changes. Trial participants who feel sexually aroused but suffer from vascular insufficiency could use low doses of a phosphodiesterase inhibitor together with the 1:200 Tongkat Ali Extract from Indonesia.

Ideal trial participants should be dedicated to the task of improving their libido and their sexual satisfaction.

The following dosages are recommended:

The dosage for the first day should just be one capsule. The dosage of the first day is not for a therapeutic effect. The dosage of one capsule on the first day is a test to make sure that a trial participant is not allergic to Tongkat Ali.

Tongkatali.org has been selling 1:200 Tongkat Ali Extract from Indonesia for more than 20 years. Until now, we have never met a person who is allergic to Tongkat Ali.

Allergies are unpredictable reactions of a person's immune systems. Some people are allergic to the strangest substances. There even are people who are allergic to water.

Standard dosages of Tongkat Ali would be 4 to 16 capsules a day. For adult males, it is hard to reach an overdose on Tongkat Ali. Our 1:200 Tongkat Ali Extract from Indonesia is an endocrine effector, with little or no influence on cardiovascular parameters.

Contrary to Tongkat Ali, phosphodiesterase inhibitors and similar erection medication dilate blood vessels. Erections are not caused by hormones. Erections are the result of the widening of blood vessels in the male genitals.

Erections can be caused by tactile stimulation or many physiological processes. Many of these processes are not related to sexual events. Men often have nighttime or morning erections, out of any sexual context. In many men, even plain sleepiness can cause an enlargement of the penis. Why? It happens because sleepiness is often accompanied by a drop of blood pressure, parallel to a widening of blood vessels.

Phosphodiesterase inhibitors like Viagra can cause a pronounced drop of blood pressure. This can be dangerous to the cardiovascular system. There could be a stroke, preluded by a severe headache. One clearly can overdose on Viagra, and death from phosphodiesterase inhibitors regularly are in the news.

Tongkat ali is largely neutral on the cardiovascular system. This makes Tongkat Ali less dangerous even when dosages are generous.

If Tongkat Ali raises testosterone levels, what would one feel? Higher testosterone levels, even from testosterone injections, don't makw people feel like they would have taken a drug. The most likely effect of high testosterone would be occasional sexual stimulation based on what people think or what they remember.

Trial participants should take a diary in which they make a note every time they have sexual thoughts. Previous clinical trials suggest that this will happen more often, compared to before the consumption of 1:200 Tongkat Ali Extract from Indonesia.

If sexual fantasies lead to intercourse, most men in midlife and beyond will still benefit from phosphodiesterase inhibitors like Viagra for purely physiological processes. The task of 1:200 Tongkat Ali Extract from Indonesia would be to add mental components to sexual intercourse, such as sexual desire and a sense of sexual satisfaction. These components are usually lacking with phosphodiesterase inhibitors.

Men and women who are interested to participate in our new clinical trial should write to us and attach a test results for bound and unbound testosterone.

Trial participants are entitled to receive 1:200 Tongkat Ali Extract from Indonesia at a discount of 50 percent.

Trial participants should have their blood levels tested for bound and unbound testosterone again after the consumption of the first 400 capsules of 1:200 Tongkat Ali Extract from Indonesia. The second lab report should again be sent to Tongkatali.org as email attachment.

Our experience with 1:200 Tongkat Ali Extract from Indonesia indicates that most men and women will achieve a substantial increase in testosterone. However, for any medication, there are people who do not respond. Our current clinical trial is designed to switch people who do not react on Tongkat Ali to combinations that also involve Butea Superba and Mucuna Pruriens.

The full tongkat ali 1:200 extract story, and a psychopath on the prowl for killings

By Serge Kreutz

Indonesian Ethnobotany, 2019

Sumatra Pasak Bumi started trading tongkat ali extract in the late 1990s when tongkat ali was virtually unknown. There only was one Malaysian company trading tongkat ali on the Internet before us. They have long stopped.

Our first tongkat ali extract was 1:50 strength. This is the strength one gets naturally, without any sophistication.

You can try this at home. Just boil 5 kilograms of tongkat ali root chips for about an hour. Then discard the roots. Next evaporate the water.

The evaporation process is more complicated than boiling the chipped root to make a liquid extract.

We at Sumatra Pasak Bumi use our own vacuum evaporation machine. Actually, the installation is bigger than a machine, so we may as well call it a vacuum evaporation plant.

The technic that we apply was invented by Henri Nestlé in 1866. It's based on standard physics. The lower the pressure that is exerted on a liquid, the lower the evaporation temperature (boiling point).

Thus, under low pressure, you can evaporate or condense milk without long cooking. You still have to heat your milk beyond 100 Celsius (centigrade) / 212 Fahrenheit for a few minutes to pasteurize it (kill all microorganisms). For this process, you need a pressure cooker, or autoclaving equipment, which, obviously, we also employ.

If you evaporated all water of your boiled tongkat ali root, you will get a hardened film sticking to your dish, glas or stainless steel, which you will have to scrap off and mill or grind. That will be your 1:50 extract, a mixture of inorganic and organic compounds. The inorganic compounds include minerals and salts. These are more crystalline than organic compounds which usually are softer to the touch.

Conventional wisdom is that the organic compounds, not the inorganic ones, account for the efficacy of tongkat ali. This is a realistic assumption because the organic compounds are specific to the plant, while the inorganic stuff is common to a fairly wide range of plants.

The 1:200 extract is derived from the 1:50 extract by mostly mechanical separation, centrifuging and filtering. We remove the more crystalline fractions which are more likely to cause gastrointestinal symptoms. From 1 kg of rather crude 1:50 extract, we obtain 250 grams of fine, heavyier 1:200 extract.

Our extracts are not fermented. There is no chemical alteration comparable to the fermentation of grape juice into wine. There aren't many proteins in tongkat ali root, but those present may become denatured during the extraction process. Denaturation means that the shape of protein molecules are changed, but their chemical composition is not.

So, is our 1:200 extract stronger than our 1:50 extract. It is certainly more strongly concentrated. But unlike your common scammer who stretches his fake powders with sildenafil analogues, we ourselves do not add anything to our product.

This means that nothing is in the 1:50 extract that also is in the raw roots, and nothing is in the 1:200 extract that wasn't before in the 1:50, or in 200 grams of dried chipped root.

So, could you just eat 200 grams of chipped root? Don't! You'd be sick. A human usually can't digest 200 grams of wood fiber. You are not a termite.

Even if you consume a tea brewed of 200 grams of chipped root, this may or may not make you feel uneasy.

On the other hand, if you swallow 4 grams of 1:50 extract, the chance for gastrointestinal stress isn't very great, and 1 gram of 1:200 extract is tolerable even for people with a sensitive stomach.

Thus, on the one hand, our 1:200 extract is milder than the 1:50. It is also more concentrated for active ingredients. Thus 1 gram of 1:200 is stronger than 1 gram of 1:50, but as a matter of mathematical logic, as there is no chemical alteration, 4 grams of 1:50 cannot be weaker than 1 gram of 1:200

One would believe that the above explanation on extract ratios is logical enough.

An Australian herbalist in Malaysia claims that 1:100 is impossible, and 1:200 is outright ridiculous.

The issue is something else. The extract he sells isn't 1:200, so he has to twist things a bit to have people buy his product.

Never mind. Compared to others, this Australian guy in Malaysia still has a fairly Western level of integrity.

It gets definitely worse when you go from Malaysia to Singapore. There, apart from very money-minded Chinese folks, you find an Arabic, probably Moroccan guy with a Spanish citizenship. That one is the most pathological figures in the tongkat ali trade, and unfortunately, psychopaths can be quite dangerous.

To start with, he suffers from a profound inferiority complex, which, of course, he tries to overcompensate. So he claims three academic titles, and presents himself as CEO, even though he just runs his distribution from his apartment.

He attempted to sell himself as magazine model, an endeavor with which he didn't get very far, inspite of his publishing himself on the net in the nude (too short, too stout), and he tried, hold yourself, a career as masturbation guru.

Who is the guy? For the sake of entertainment, let's play Hitchcock on that question. Sooner or later, I'll tell you, or you will find out yourself. But careful. This is a psychopath, and you could fall victim. He forges his bio, and he forges credentials for his tongkat ali scam, and we have notarized proof (falsified documents based on our originals).

On the other hand, this person is not the only scammer in the tongkat ali trade, just the most childish one.

Scammers come and go, mostly at the mercy of Google. If Google gives them a rank, they can trick the public into buying their warez.

For some time, the claim of tongkat ali extract using alcohol as medium of extraction made the rounds. Baloney, of course. The cost for a commercial product using alcohol as extraction liquid would be far too high. And excise depatments around the world would charge any alcoholic-extract operation into bankruptcy.

Next came the eurypeptides bogus science. It's a goner, no need to elaborate.

Currently en vogue is "standardization" for eurycomanone. Many peddlers claim it, with ever increasing percentage, I am just waiting for a con artist who attempts to convince the public that his tongkat ali extract is 110 percent eurycomanone.

Our Arabic-Spanish Singapore psychopath, determined not to be outdone, already claims a tongkat ali extract that is both 1:200 and standardized for eurycomanone, not realizing that this is a logical fallacy.

As the eurycomanone percentage in tongkat ali is not consistent, a 1:200 extract would have some natural variation in eurycomanone (not every 200 kg have the same content). If an extract were standardized for the marker chemical eurycomanone, then the quantity of root equivalent would vary.

Psychopaths are lacking in the logical department. That is why our Arabic-Spanish specimen thinks it's a good idea to place Google ads warning against a 1:200 ploy, and then tries to sell readers "standardized 1:200".

But then, he also tried a career as maturbation guru. Was Dr. Kellog right after all about masturbation and mental health? Dr. Kellog developed corn flakes as breakfast dish to stop that certain practice, and ensure children's sanity.

Why all the fuss about eurycomanone anyway? The Forestry Research Institute of Malaysia has suggested that eurycomanone be used as a marker compound in identifying tongkat ali as ingredient in herbal concoctions. This makes sense because eurycomanone is a constant constituent of tongkat ali, and, apart from cellulose, the most abundant.

Article continues below printscreens

That doesn't mean that eurycomanone would be the chemical compound responsible for tongkat ali's effects. The amount of scientific research into eurycomanone is thin. The vast majority of scientific studies were made with full-spectum tongkat ali extract, not eurycomanone isolates.

Sumatra Pasak Bumi is dedicated to testosterone enhancement by means other than the outright injection of anabolic steroids or testosterone replacement therapy by patches or oral testosterone undecanoate (Andriol testocaps).

Anabolic steroids or testosterone patches or caps are not a satisfactory solution because some of the benefits of testosterone are related to the body's own synthesis of the hormone.

One side effect of exposing the body to exogenous testosterone is genital shrinkage. It's not the testosterone itself that makes for large genitals, but the fact that a lot of testosterone is produced by the genitals.

The most important downside of direct exogenous testosterone is that it messes with the whole hypothalamic-pituitary-gonadal axis.

The chain of events along this axis is, roughly, like this: low testosterone makes the hypothalamus synthesize and release gonadotropin-releasing hormone. Gonadotropin-releasing hormone activates the production of luteinizing hormone and follicle-stimulating hormone by the pituitary gland. And luteinizing hormone and follicle-stimulating hormone communicate to the male and female gonads (testes and ovaries) to increase levels of estrogens and testosterone.

This description is as simplistic as saying that a car is a machine with wheels, and if you put diesel in a tank, it makes a fire and travels. It also has a horn to tell obstacles to move out of the way, and it has a break, in case they don't.

You cannot explain a car in a few sentences. And neither can you explain the endocrine system in such brevity.

But certainly, bypassing the hypothalamic-pituitary-gonadal axis and just supplying exogenous testosterone is as crude a therapy as tuning a sluggish car by changing tires. It may or may not have the desired effect.

Most people understand cars better than their own endocrine system. Because cars are less complicated.

A theoretical approach will not do the trick of reviving a sluggish libido. An empirical approach is more promising. And the experience of traditional medicine with tongkat ali, butea superba, and mucuna pruriens clearly suggests that these herbals increase relationships drive and usually result in higher testosterone levels. How exactly this happens isn't clear. But definitely, it's more complicated than tongkat ali, butea superba, or mucuna pruriens communicating directly with Leydig cells, telling them to turn out more testosterone. There will be multiple anchor points along the hypothalamic-pituitary-gonadal axis, possibly by a variety of pythochemicals found in tongkat ali, butea superba, and mucuna pruriens, and these phytochemicals will likely not only work on the endocrine system but also involve cross-connected neurotransmitters of the brain, notably dopamine.

Details unknown.

Just be an empirical person, not a theoretical one.

And, apart from considerations on the active ingredients and anchor points of tongkat ali, butea superba, and mucuna pruriens, here another piece of empirical science which shapes the trade policies of our company, Sumatra Pasak Bumi.

There is mounting evidence that plastics, most plastics, are an important factor in declining male fertility, lamented around the world. The culprit most acutely identified is bisphenol A, a hard plastic traditionally used to manufacture water bottles.

Bisphenol A is a hormonal disruptor. It leaches measurable amounts of chemicals with estrogenic activity. These chemicals act like estrogens on the hypothalamic-pituitary-gonadal axis as negative-feedback signals. They tell the hypothalamus, pituitary gland, and gonads that enough of the natural steroid hormones testosterone and estrogens, are already circulating in blood plasma, and thus don't need to be further synthesized.

A fatal chain reaction for mankind, mostly men, because these envirinmental estrogens cannot replace testosterone in spermatogenesis, nor for libido, relationships desire, relationships function, orgasm, and relationships satisfaction.

Bisphenol A was the first plastic distinctly identified as hormonal disruptor, but scientist took the lead and investigated other plastics as well.

The result: most plastics, and quite possibly all, leach chemicals with estrogenic activity.

Do you still drink water from plastic bottles? Keep food in plastic containers? Buy health supplements in plastic packaging?

Better stop.

Especially if the issue is herbals for relationships enhancement.

Sure, we have traded tongkat ali extract in plastic bottles for decades, and many of our customers achieved beautiful results.

But we have seen the writing on the wall for plastic, and, as a sign of the times, have switched to package our extracts in double-layer or thick-layer paper bags before putting them into plastic bottles needed for light-weight international shipping. Thus, there is no contiguity of our plastics or extract powders with plastics.

Packaging in paper bags isn't feasible for amounts of 100 capsules, thus our new line of products is 400 capsules per container.

Anyway, the dosages for a noticeable effect from sexuality-enhancing herbals, classified as food, not as drugs, are in the range of several grams per day, and for such a regimen, single bootles of 100 capsules don't get you very far.
