A large number of men who are very good in making money, greatly lack on wisdom on how to spend it. Instead of utilizing their funds to purchase optimal sexual health, and optimal sex, and thereby extend their own lifespan and nurture their karma, they hoard wealth for their children (who will be thankless…​ but take the money anyway), or donate to charities (hahaha). Man, get real. Spend your money on optimal sex, all of it, before you die.

For a man in his 50s, 60s, or 70s, what would you pay to get back the sexual excitability of when you were 15, 16, or 17. If you are wealthy enough, and sure that the regimen will work, pretty much anything. You can’t take your money with you when you die, but sexual excitability of a degree as if you were a youngster will generate an aura of health that makes you live longer, and if you feel that you have a soul, then optimal sex will nurture it, and give it more power and potency. The key to all of this is pharmaceutical, and a combination of butea superba and tongkat ali may just be it. Butea superba is a direct phytoandrogen; it acts like testosterone without being testosterone. And tongkat ali avoids that in response to butea superba, the body reduces its own testosterone synthesis.

If you are religious in the Kreutz context, then you know that your soul, and quite possibly your eternal life, or the eternal life of your soul, or karma, is a matter of having optimal sex, and the best possible orgasms, in this life, now and here. This divine path, and not the accumulation of wealth, and not morality or doing good, is the only sensible reason for being alive, and the only valid measure of success. But so-so sex will not qualify. This is why neuropharmacological help is so important, and sexual enhancement essential.

Life is biochemistry. What ever we do, whatever we think, is just an expression of chemical processes within our bodies. Optimal sex, too, is an event in biochemistry. And this is why it can be engineered with pharmaceuticals, which includes androgenic herbals. Pharmacology just hasn’t had the opportunity yet to isolate the most orgasmic components of tongkat ali and butea superba.

The aromatase conversion of testosterone into estrogens is of great concern to bodybuilders as it can lead to gynecomastia and reduce the muscle-building effect of testosterone. The eurycomanone of tongkat ali is an effective aromatase inhibitor. This has resulted in the distribution of numerous fake tongkat ali products claiming high eurycomanone content. Tongkat ali buyers are advised to tread carefully when shopping for tongkat ali. Offers that are too good to be true, inevitably aren’t.

Depending on your inclinations, you may call it borderline science or cutting-edge science. But one way or the other, sexual excitement and orgasmic pleasure generate a form of energy which evaporates from, and reflects back on the human body that generates it. Wilhem Reich named it orgone. He propagated the concept, which doesn’t mean that he was right in every detail. Nevertheless, the healing power and the life-extending potential of the energy generated by sexual excitement and orgasmic pleasure is unrivaled. This doesn’t necessarily mean that sick children ought to be treated with porn clips. But if you are old, and you want to be younger, great sex is your best bet. And if science will ever come up with proof for a human soul, it will inevitably be tied to libido energy, of which romantic love and divine agape are just expressions. Yes, we are preaching a modern religion, here. But no, we do not discard science but firmly believe in it.

While tongkat ali primarily operates on hormonal pathways, scientific studies on butea superba indicate a more direct effect on the male vital organ. A study on male mice found that butea superba extract increased intercavernosal pressure. Intercavernosal pressure relates not just to erection size, but erection hardness. These are two different parameters. While drugs like Pfizer's Blue do a great job inducing and maintaining erections, these drugs cannot make erections glass-hard as, for example, yohimbe does.
Beyond doubt, yohimbe, and its extract yohimbine, are the most powerful herbal sexual enhancement drugs. Even better than Pfizer's Blue.

As established in a widely cited scientific report, butea superba can sharply increase sex hormone levels and sexual desire in men, even to a disturbing magnitude. While most men would just be happy with heightened libido, thank you, and not consult a physician for it, the increase of sex hormones and sexual desire from butea superba can be pathological.

Similar to yohimbe, the bark, or yohimbine, the pharmaceutical extract, butea superba can increase intracavernosal pressure. In simple English, it has a tendency to make erections harder. This obviously is a desired effect for many men. For many men, the side effects of yohimbe or yohimbine (tachycardia, insomnia) are so strong that they have to forego the desired effect of increased intracavernosal pressure. For such men, butea superba could be a viable alternative.

Dosage and cycling information for genuine tongkat ali extract

This dosage information applies only to genuine tongkat ali products of Sumatra Pasak Bumi. It does not apply to the numerous fakes of scammers whose expertise is Google manipulation in order to rank high on tongkat ali searches, but sell cheap tribulus terrestris or tongkat ali root powder, not extract. If an alleged tongkat ali product is not accompanied by photographic evidence from harvest to shelf, always assume it is tribulus terrestris.

For tongkat ali 1:50 extract, the standard dosage for men is 1.6 gram (1600 mg) to 3.2 gram (3200 mg) per day. Weight lifting athletes may go to twice or even four times that dosage. Women should start with one quarter of male dosages, and work themselves up to half of male dosages.

For tongkat ali 1:200 extract, the standard dosage for men is 1.2 gram (1200 mg) per day. Weight lifting athletes take up to 2.4 gram (2400 mg) per day. First-week dosages should just be one quarter of standard dosages, and second-week dosages should be one half of standard dosages.

For optimal results, tongkat ali should be cycled. It is also important to follow the dietary recommendations given below. If the dietary recommendations are not observed, tongkat ali may have little or no effect. Certain plant foods cancel the effectiveness of any nutritional or supplemental testosterone support and should therefore be avoided.

TONGKAT ALI CYCLES

Tongkat ali should be cycled. This means that one takes it for some time, and then, for a shorter period of time, one goes without it. A standard cycle schedule would be 2 weeks on, 1 week off. Optimal on-cycle length varies among users.

Older users often have the best results with short cycles. The cycles may be as short as 4 days on, 2 days off.

Most users on longer cycles will experience a rising phase during which effects of hormonal support build up. This means that for many users, there will be little effect on the first day or the first few days of a cycle. They then reach a high phase during which tongkat ali exerts its effect. In younger users, this phase can last several days. After that (still during tongkat ali use), one will enter a falling phase, caused by the body adjusting to the tongkat ali through negative feedback systems.

This is a normal occurrence with anybody's endocrine system. Whenever hormonal balances are influenced, the body will aim to return to genetically determined age-related set points (even if these set points are not optimal for health, and certainly not optimal for sexual conduct). Because tongkat ali itself is not testosterone or a hormone, negative feedback mechanisms are delayed.

The aim is to use nutritional measures to induce higher testosterone levels without the negative effects of steroid use, such as testicular and penile shrinkage, and libido impairment.

However, as the body has many ways to regulate hormone levels, there is a point when raised testosterone levels, even when caused by nutritional intervention or behavioral measures, will start to drop. It is best to then go into an off-cycle right away. Off-cycles typically should be about half as long as on-cycles. Thus, if one takes tongkat ali for 2 weeks, the off-cycle should be about 1 week in length.

An alternative strategy, especially for bodybuilders, is to cycle tongkat ali and butea superba. Both herbals are androgenic, which means that they increase testosterone tone. But they do so on entirely different pathways.

Tongkat ali itself is not a testosterone equivalent. Rather the opposite. Tongkat ali signals the endocrine system that there isn’t enough testosterone around. So the Leydig cells go into overdrive, synthesizing more testosterone. This works for some time, until the body recognizes the trickery, and, via the negative feedback loop, reduces testosterone synthesis.

It’s a totally different story with butea superba. Butea superba acts like a testosterone analogue, with an affinity for testosterone receptors while at the same time not subject to an aromatase conversion into estrogens.

These properties make butea superba ideal for use during tongkat ali off-cycles as it allows Leydig cells to rest, while at the same time maintaining a high testosterone tone.

However, caution is advised with butea superba as its testosterone and libido-enhancing properties are less predictable. Cases of extreme testosterone agitation, both sexual and organic, have been clinically reported for butea superba supplementation.

DIETARY GUIDELINES

Tongkat ali on-cycles and off-cycles should be accompanied by different nutritional strategies. In order to support testosterone synthesis while on tongkat ali, an on-cycle diet should include fair amounts of protein and fat of animal source.

Fish and seafood should be avoided during on-cycles because it can lead to allergic reactions.

To achieve primarily prosexual effects, it is recommended not to consume loads of carbs-rich foods during a tongkat ali on-cycle (bread, rice, pasta, potatoes).

For those who have a hard time to manage their diets for nutritional benefits only, while having to forgo the taste and pleasure rewards of food, the Serge Kreutz diet on sergekreutz.net will offer an elegant solution.

If one uses tongkat ali exclusively for bodybuilding (as opposed to pro-sexual parameters), a sufficient supply of carbs are a necessary part of the diet plan. In that case, the carbs should be eaten once a day, approximately 1 hour before training. The tongkat ali should be used after the training session, and again at the hour most distant from the training session.

Broccoli, cauliflower, soy-based foods, and garlic can have disruptive effects on natural testosterone support. One should therefore not consume broccoli, cauliflower, soy-based foods, and garlic during on-cycles.

In order to avoid overall nutritional imbalances, the off-cycle diet should be different from the on-cycle diet. During off-cycles, one’s diet should emphasize vegetables and fruit, with little meat, cheese, and eggs. Protein during off-cycles should come mainly from fish. Broccoli, cauliflower, and soy-based foods, are good dietary choices for off-cycles.

Furthermore, during off-cycles, whole-grain breads are well suited to prepare the body for the next on-cycle.

Once one is ready to again use the tongkat ali, one should stop eating whole-grain foods as well as vegetables, and switch back to a diet strong on meat, cheese, eggs, and nuts.

Strange as the proposition may sound, it is best for tongkat ali users to avoid drinking water in plastic bottles, as this may interfere with a testosterone-positive diet agenda. Water and other drinks from glass bottles are a safer bet.

DRUG AND FOOD INTERACTIONS

Please note that for legal and common-sense reasons, we never advise anyone buying our tongkat ali products to modify any drug regimen that has been decided on by the buyer’s physician. Furthermore, if you do take prescription drugs on advice of your physician, it is a good idea to ask him or her whether tongkat ali will interfere with your medications.

Tongkat ali is not a medicine in the sense that it would be suitable for the treatment of specific diseases.

Rather one should think of tongkat ali as a tonic that turns good or decent health into optimal health by providing nutritional and supplemental support for the testostetone synthesis by one’s own body.

If you take tongkat ali extract to support libido, you should not combine it with saw palmetto or pygeum. Furthermore, we suggest that people stop using the pharmaceutical finasteride (Proscar) for its vanity application, which is to slow down the rate of scalp balding. However, patients who are prescribed finasteride in the treatment of benign prostate hyperplasia should definitely not stop using finasteride without consulting their physician first.

Saw palmetto, pygeum, and finasteride all interfere with dihydrotestosterone synthesis. The enzymatic conversion of some testosterone into dihydrotestosterone is generally though to increase libido, but it is not considered the only pathway by which a body achieves this.

If taken for pro-sexual purposes, one has to be aware that tongkat ali mostly supports libido, not erectile function. For this reason, if you are above 45 and take tongkat ali to enhance libido, you may want to obtain a physician’s prescription for a phosphodiesterase inhibitor.

For a combination of tongkat ali extract with a standard erection medication, the following usage schedule works best. Some three to four hours before expected sexual intercourse, take half the daily dosage of tongkat ali extract with a full meal. For one to two hours after this meal, your testosterone levels will be below average (large amounts of food suppress testosterone). Your testosterone will see a natural rebound some two hours after the meal. This is when the nutritional and supplemental hormonal support can also start to kick in, raising your testosterone above daily averages.

It is then best not to eat again until after sexual intercourse. Eating again before sexual intercourse may cause the effect of hormonal support to diminish. About 1 or 1:30 hours before expected intercourse, one would add the Pfizer's Blue.

Please be aware that the above suggested course may cause a noticeable histamine reaction. Facial flushing and a stuffed nose are typical indications of a histamine reaction. These are also indications that sexual intercourse will likely be more exciting and satisfying than normal.

TONGKAT ALI SIDE EFFECTS

Side effects are not much of a concern with tongkat ali, especially in those who have taken it for some time. Nevertheless, if your health isn’t optimal, you may want to use less than the standard dosage for a few days, and then increase slowly. Furthermore, older people will usually have a stronger effect from tongkat ali, and side effects are more likely in older users.

Initial side effects could be facial flushing, headache, and testicular pressure. Regardless of your age, these side effects will subside after a few days. Penile and testicular hypertrophy (increased size) can be a long term side effect, especially with the use of very large dosages, and in those who use tongkat ali at a younger age. This effect can be traced back to testicular Leydig cells inducing growth of surrounding tissue. (Penile and testicular size increases during puberty, are caused by the activation of testicular Leydig cells and the subsequent increased testosterone secretion by these cells). Size increases during Leydig cell activation, during puberty, do not reverse.

AGGRESSIVENESS

Conventional wisdom is that nutritional and supplemental support for testosterone synthesis could cause a person to get carried away much more intensively during intercourse than he or she would without it. Testosterone-enhanced sex will likely be more aggressive than usual. In order to get the best (and the best sex) out of nutritional and supplemental testosterone support, it is important to accept the aggressiveness as a component of increased libido. Stop taking the tongkat ali when strange sexual desires appear. Please be aware that strange sexual desires are a potentiation of normal sexual desires, and that virtually anyone can develop aberrant sexual inclinations when testosterone levels are sufficiently raised.

TONGKAT ALI FOR WOMEN

By and large, tongkat ali has the same effect on women as it does on men. In Southeast Asia, women take tongkat ali to support fertility as well as libido. Most commonly it is used by those who take hormone-based contraceptives (the pill). Indonesian women typically have 2 complaints about contraceptive pills: that they make them fat, and that they interfere with sexual pleasure. Many of them believe that tongkat ali keeps them both slim and interested in sex (tongkat ali will not override the contraceptive effect of pills, though). The dosage recommendation for women is to take about half as much as men.

There is no use of tongkat ali for date rape intentions or machinations. Because of its extremely bitter taste, it cannot be mixed secretly into drinks.

MEASURING QUANTITIES

If you obtained our loose extract powder in pouches and want to measure exact quantities, you will need a scale. If you want to order a cheap but exact scale, you can do so through the website www.saveonscales.com. There are other sites with equal or even better offers.

On the other hand, whether your dosage is 0.8 gram or 1 gram or 1.2 gram of our 1:50 extract, or a 0.6 gram or 0.9 gram of our 1:200 extract, does not make a difference in principle. It’s not that 1 gram of 1:50 extract would be an efficient dosage, and 0.8 gram not.

It’s just like with coffee or tea. People do not use a scale to measure 3 gram per cup, but just take approximate amounts, based on their experience. In the case of tongkat ali, it’s a tip of a teaspoon. Of course, not all teaspoons are the same size. If we use our own standard kitchen teaspoons, a heaped teaspoon is about 7 gram (too large a dose). A leveled teaspoon is about 2 gram, so slightly less than a leveled teaspoon would be a single standard dose.

MIXING EXTRACT

If you have obtained loose tongkat ali extract (not capsules), it is best to dissolve your dose in half a cup of tepid water and then swallow it in one go. Because of the bitter taste, many people prefer to take a bite or two of some food right afterwards. Obviously, if you obtained capsules, you do not have to worry about the taste, and how to best get the tongkat ali down.

If you obtained loose extract and cannot “stomach” the taste, you can buy empty capsules in pharmacies anywhere in the world. Suitable capsules sizes are 00 (larger) and 0 (smaller). You can fill capsules easily by hand, though they won’t be filled entirely if you do not use equipment. If they are filled by hand, 0 size capsules hold about 150 mg of our 1:50 extract, and 00 size capsules about double as much. Our 1:200 extract is about 30 percent heavier than the 1:50 extract.

CHIPPED ROOT AND ROOT POWDER (AS OPPOSED TO EXTRACT)

Tongkat ali chipped root and root powder are intended to be boiled as a tea. It is not advisable to consume the root powder raw, or to fill it into capsules. We do want to put emphasis on this, as root powder is commonly sold over the Internet by US-based distributors (in pouches or as capsules), without advice that it must be boiled; raw tongkat ali is likely to cause diarrhea.

A standard dosage of tongkat ali tea is prepared from 25 to 50 gram of chipped root or root powder, boiled for at least 5 minutes. A first-day dosage should be half of a standard dosage.

Dried root powder is primarily cellulose; the active ingredients are a very small fraction. Thus, the amounts of root powder (or chipped root) used per single dosage are rather large (25 to 50 gram as standard dosage, boiled for at least 5 minutes).

 

Dosage information for butea superba extract


To make dosing easy and convenient, our butea superba 1:120 extract is shipped with a small measuring spoon. A levelled measuring spoon (see photo) has a weight of 40 milligrams. A heaped measuring spoon is 100 milligrams.

Our butea superba extract is potent, and on some people, the libido-enhancing effects of butea superba extract can be profound. We thus suggest that any newcomer to this herbal starts with an initial dosage of just one levelled measuring spoon (40 milligrams) on the first day. If no negative side effects are recorded, the second day dosage can be a heaped measuring spoon (see photo) . From that point on dosages can be doubled every day up to 2 grams, provided there are no ill effects..

Some people feel increased testosterone tone as a stronger heartbeat. This in itself is not unhealthy. But it would be if this increased testosterone tone were to manifest itself as heart palpitations..

We know Thai men (some of our workers, actually) who consume 10 grams of our butea superba extract on a day, and swear by its virility enhancing effects. This, however, is not recommended for users without a history of butea superba extract consumption..

Please note that our product is a concentrated extract, not the cheap root powder commonly sold. Root powder is worthless..

In an effort of window dressing this fact, some large chains sell root powder with a description saying “full spectrum” butea superba. But some 98 percent of this full spectrum is just cellulose with a potential of gastric distress. After all, the digestive tract of humans isn’t laid out to process saw dust that even ruminants refuse..

Sexuality enhancing herbals

Sumatra Pasak Bumi is a distributor of Asian medicinal herbs, with a focus on plant extracts that have been used for ages in Asia to enhance the sexual function and sexual pleasure of men and women. Our initial focus was on tongkat ali, which we have been distributing since last century. Our principal website is still named tongkatali.org, and our company is registered as Sumatra Pasak Bumi (pasak bumi is the Indonesian name for tongkat ali).

We have later added kacip fatima (a libido herb for women), and sirih leaves, kayu rapat, and manjakani, three herbs for female genital care.

By and large, there are many more sexuality enhancing herbs for women (phytoestrogens) than there are for men (phytoandrogens).

Indonesia only has one additional maleness-enhancing herbal, daun bungkos, but that one doesn’t work on the hormonal pathway but is used for penis enlargement. We source it in Papua New Guinea, some 6000 kilometers away.

We sell a whole lot of other herbals, from Indonesia and China, that support not sexual parameters but general health. However, our pioneering efforts have always been in the sexual arena where herbal enhancement is most rewarding, especially for men.

We have scouted and sourced all over Asia, but the country richest in male-supporting biodiversity is Thailand. So it’s maybe not accidentally that Thailand has long been a paradise for men in other aspects than herbal medicine.

Apart from tongkat ali, which also was common in Thailand before it was depleted, this kingdom also features butea superba and grachai dam.

Thailand isn’t integrated into the Western World to the same degree as Indonesia. Thailand never was a colony of a European power, and doesn’t use the Roman alphabet, so scientific research into Thai ethnobotany was scarce. This, however has changed, and there is now solid scientific research backing traditional knowledge that butea superba and grachai dam can revive a man’s sex life, and make good sex extraordinarily fantastic.

We have distributed butea superba more than 10 years ago, but only as a sideline. Recent research has made it a necessity to put it on a track parallel to tongkat ali.
