On our English pages, you often see the word "relationships". This is just sanitized language. On our English pages, "relationships" refers to what couples, when not sleeping, do in bed. Or, if so inclined, on the kitchen table.

English is a rather hypocritical language. Many words for natural bodily functions and processes have dirty connotations, and polite speakers like us have to go to considerable length to communicate meanings without naming them. But we nevertheless hope you get the point.


Kreutz Religion and universes


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


It’s not just that you and me, we live in the same universe. We, you and me, too, are separate universes in ourselves, hosting a plethora of organisms and phenomena.

Organisms for which each of us are an universe, or biome, that is as diverse as earth is outside ourselves. Not just viruses, bacteria, and fungi, but also events of nature. And like galaxies, the biomes we call humans do have a death.

Isn’t it funny, from the perspective of viruses and bacteria, that they live in a universe that has consciousness?

And why should this funniness not also apply on a larger scale. How can we be sure that we ourselves do not live in a larger dimension which has its own consciousness.

It’s logically obvious that the physical universe in which the earth circles the sun, isn’t the whole world, and cannot be the only universe. Our universe has set points of time and space, the big bang, and is traveling on a time axis, and steadily expanding. This can be observed and measured.

But plain logic dictates that a start point of time can only exist when there has been time before the start point, and space can only expand within space. Thus, our universe, from the big bang until now, can only be a small part of a larger world, one of an unlimited number of universe. The number of universes must be unlimited because this is the only mathematical construct that escapes the logic that deliminated space can only be in larger space.

Microorganisms for which humans are a biome have no means of being aware that they live in an environment that has feelings and consciousness, even though many of these feelings, and even human consciousness are modified by them and result in specific behaviors, and even accompanying rationalizations.

As a striking example, dogs afflicted with rabies bite, even if previously, they were docile like sheep. This behavior, of course, is what the virus needs for its own survival, long beyond that dog is dead.

And why will humans, when they have a cold, likely sneeze. The most plausible explanation is that it’s helpful for viruses to get from one biome, or universe, to the next.

Humans are proud of their free will because they don’t grasp the extent to which their behaviors, and their thoughts, are manipulated by the populace within them.

Humans think of human sexuality as a means of human reproduction. But beyond that, human sexual intercourse is also the preferred avenue for a large number of microorganisms to secure their own prevalence.

And these microorganisms have the distinct evolutionary advantage of a generational turnover rate measured in minutes, not decades.

In line with this train of thought, the jury is still out on whether or not a particular strain of herpes wouldn’t be the must efficient treatment of erectile dysfunction, premature ejaculation, or low libido.

And if humans ever will succeed to expand their individual lifespans to 500 or 1000 years, infecting individuals with appropriate strains of microorganisms may just be the right technology.

From the perspective of the living beings within us, we, each of us, are an environment. Microorganisms within us have no means to realize that we humans are entities who generate feelings, art, and philosophies, even though these microorganisms do shape our feelings, and ultimately, our ideologies and religions. From the perspective of these microorganisms, they just modify a material world, which happens to be we.

But if microorganisms can produce human behavior, and, ultimately, what we consider rational explanations for such behavior, it is not inconceivable that human behavior on its part also generates something that is as distant from human everyday behavior as human libido may appear distant from the evolutionary advantage-taking of the herpes virus.

And this justifies the perception that human orgasmic release generates karma which is there, somewhere, outside and beyond our physical existence.


Genuine tongkat ali is no health risk, even at a generous dosage

But fake tongkat ali kills.

Just consider the news of the past few month. 40,000 sachets of fake tongkat ali coffee seized in Malaysia, Zambia has it's own scandal of fake tongkat ali, and in the US, another fake tongkat ali coffee from Malaysia / Singapore has been recalled.

Most fake tongkat ali is a root powder, which may or may not be tongkat ali, laced with a sildenafil analogue.

Mind you, Pfizer's Viagra is sildenafil citrate. Analogues may be other salts of sildenafil, or a sildenafil, altered on a side string without clear pharmaceutical effects.

Analogues of sildenafil have been around from the time when sildenafil citrate was still patented.

But when you shop for tongkat ali you probably don't want a phosphodiesterase inhibitor.

Sure, phosphodiesterase inhibitors cause erections alright.

But genuine tongkat ali enhances testosterone, with a great positive effect on mood and general well-being.

And these are effects that are clearly felt with our genuine products, but never with fakes.

Yohimbe and sleep


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


For me, the worst side effect of yohimbe is that I cannot go to sleep for at least 20 hours after having ingested even just a small amount of the herbal.

This is not the case for all those who try yohimbe. Some people sleep perfectly normal, even after ingesting yohimbe just two or three hours before retiring. It’s the same group of people on whom yohimbe also doesn’t have much of a relationships effect.

However, in those subjects in whom yohimbe (the root) in dosages equivalent of 5 to 20 milligram yohimbine (the active ingredient) has a pronounced pro-relationships effect, the dosage needed for sleep avoidance is considerably less than the one for pro-relationships effects.

If yohimbe is taken daily, the sleep problem typically is worst on the first day.

My own approach is to take yohimbe on one day, and on the next day not to take any, as I really feel that I need yohimbe-undisturbed sleep in the second night.

Another approach (which I think is inferior because it diminishes the pro-relationships effect of yohimbe) is to take it every day for about a week or two, and then to take a few days off. When I followed this approach, I slept a lot on the off-days, up to 12 hours. On the first off-day, it may even have been 16 hours.

By taking yohimbe in cycles of a week or two, I achieve an almost normal sleep pattern after two or three days. In the first night of such a yohimbe cycle, I usually did not sleep at all. When I was lucky, I did get some sleep before noon on the next day. On the second day, I took my daily yohimbe dosage directly after having had a little sleep (as little as two hours). The next night, I got to sleep at 2 or 3 in the morning, and actually slept for five or six hours. On the third day, I would ingest my yohimbe only a few hours after waking up, to have the ingestion time closer to the most likely time for relationships intercourse. Sleep would still be light, but I could be quite sure that I would get some sleep. On following days, I would have an almost normal sleep pattern, so sleep would be light.

The crux with this approach is that I during such a course, the yohimbe loses its pro-relationships power. This of course defeats the logic of any yohimbe regimen.

I have tried everything I could think of in order to force sleep after taking yohimbe when not having ingested any on the previous day. Nothing really works.

The worst has been melatonin. After having ingested yohimbe, melatonin does nothing to get me to sleep. It just makes me feel drowsed until it is cleared from my system.

Kava-kava doesn’t induce sleep after yohimbe. But it does make me feel more relaxed while still being kept awake by the yohimbe.

A tea that contains valerian helps a little bit in falling and staying asleep after yohimbe usage. It doesn’t work all the time, though. But unlike melatonin, it doesn’t make me feel drowsed when it doesn’t induce sleep.

Valium, on the other hand, does make me feel typically valium-drowsed. It may force sleep for an hour or two, but I don’t find the Valium-induced sleep sufficiently regenerative. I prefer not sleeping for 20 hours after yohimbe ingestion over two hours of Valium sleep.

I have tried one herb that on the occasion of trying it did induce sleep. It also reverted the pro-relationships effect of yohimbe, so I do not see much wisdom in pursuing its use. I cannot even recommend it for inducing sleep, if just for the reason that this stuff is outlawed in many countries (but not the Netherlands). I’m talking about marihuana.

I have seen reports that actually promote marihuana as an aphrodisiac. But I have also read reports on alleged pro-relationships capacities on almost every herb, even such strong anti-relationships herbs as saw palmetto or pygeum. It’s usually obvious why claims to pro-relationships activities are made: people want to sell their wares.

In the case of marihuana, those who seek the weed’s legalization increasingly take the route of promoting the benefits of “medical marihuana” the use of marihuana to treat specific conditions, ranging from eye pain to epileptic seizures.

Wouldn’t it be great if marihuana also were of use to treat relationships dysfunction? As a viable alternative to sildenafil citrate, who would dare to prohibit its pharmacological use?

Fewer people would be enticed to support marihuana legalization if its pharmacological use shall be to dampen a patient’s libido. There are already enough dampeners on the market. Unfortunately, marihuana’s effect on relationships function is exactly this: to dampen it, which is not surprising for a sedative.

After marihuana use, a certain dumbness will engulf one’s body, described as being “stoned”. This dumbness also extends to the primary reproductive organ, making its proper use (and the enjoyment to be derived from that) more difficult.

But, as mentioned above: marijuana has some efficacy in putting you to sleep after yohimbe ingestion. (Don’t plan another round of pleasure after your smoke.)



Sirih leaves to restore virginity, not just the hymen


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


However, I want to bring the attention of the reader to a relationships supplement which is not consumed orally: Indonesian sirih leaves.

Sirih leaves are boiled and then used as a genital wash, not by men, but by women. Indonesian women use it widely after giving birth, and they do so explicitly to make their husbands happier.

Sirih leaves cause genital shrinkage in women, as well as genital dryness. Western medicine of course deals with vaginal dryness - as a problem of post-menopausal women.

However, for women in their late twenties and thirties, the problem is not so much vaginal dryness but vaginal wetness - not for their own pleasure but for the pleasure of their partners. Many women in their twenties and thirties, when they are properly aroused, get rather flooded.

Now, this may be OK for their own pleasure. But a lack of friction reduces both the physical pleasure of the male partner, and, even more so, impacts negatively on his psychological excitement.

I think that Asians, by and large, have a more mature approach to relationships pleasure. Asian men greatly value relationships conduct with women who have no or little relationships experience. Western men are largely ignorant about the pleasure one can have with a woman who had no or little relationships experience, because Western culture dictates that the male and the female partner be of approximately the same age.

However, boys in their late teens cannot value a female relationships partner who has had no or little relationships experience. Boys in their late teens typically ejaculate too fast. They are also too nervous, or too excited, to enjoy the finer points of a relationships encounter. It has long been my opinion that the best partners for boys in their late teens are women around 30 who take the initiative.

The relationships which mature men can have with virgins or women with very little relationships experience is different. It is slow-paced. There is no need to hurry. Such relationships is very gentle, even careful, so that the girl is not hurt.

However, such relationships is only possible if there is proper vaginal tightness, and even a certain degree of vaginal dryness. That mature men so easily fall deeply in love with virgins or women who had very little relationships experience has a lot to do with the physical constellation of the vagina of such relationships partners.

No mature woman, with a long history of relationships conduct, can give a man this explicit pleasure of reaching orgasm with almost no movement, caused by a female partner's vaginal tightness and dryness.

Unless she uses sirih leaves.

What sirih leaves can achieve is simply magnificent. In women who respond well, it practically reinstates virginity… not through the presence of a hymen, but because the vaginal canal just feels and reacts as if the woman were a virgin (inclusive the pain).

How are sirih leaves used? Some 10 to 20 leaves are brought to a short boil. The water is then left to cool down. This water can then be used to simply wash the female genitals. However, more effective is to have the water in a small basin, and then to sit inside for 15 to 30 minutes.



Tongkat ali, mucuna pruriens (velvet beans), testosterone, and dopamine


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


Natural Dopaminergic Research, 2019


I started with relationships enhancement some 30 years ago. My first attempts were with amino acids, and my first successes with yohimbe.

My next phase were dopaminergics. I have written extensively about the use of dopaminergics in relationships enhancement.

Before, after, and in between the above, I had tried, off and on, all kinds of hormonal therapies. I didn't have any success with them.

I have been using only a combination of tongkat ali and cheap Indian sildenafil citrate (generic Viagra).

This doesn't mean that I would have turned against yohimbine and dopaminergics. These medications do work (though I recommend dopaminergic velvet beans in a stack with mildly dopaminergic tongkat ali, rather then dopaminergic pharmaceuticals). But they all work in different ways. And I assume that it lies in the dialectical nature of our sexuality that all relationships enhancement medications loose some of their kick as we get used to them. Just as routine can be a grave for relationships excitement, routinely used relationships enhancement medications tend to loose their effectiveness.

I mentioned that relationships enhancement medications like dopaminergics, hormones, or tongkat ali work in different ways. First of all, one has to differentiate between medications that work on penile plumbing and those that work on the neurological wiring.

Erectile failure in most cases is a localized vascular problem: blood vessels have to supply a sufficient amount of blood to the corpora cavernosa and the corpus spongiosum, and drainage has to be avoided. This is all rather mechanical, and it can be achieved pharmacologically either by sildenafil citrate or yohimbine, or generous dosages of krachai dam in a tongkat ali stack. Krachai dam is a low-affinity phosphodiesterase inhibitor.

When Viagra was not available yet, yohimbine was the only oral drug to specifically treat erectile shortcomings. Another option was injectable prostaglandin E1 (alprostadil). Alprostadil is now available as cream.

Other medications were (and are) useful for relationships enhancement only when there were (or are) no erectile but only neurological relationships problems. If the problem is vascular, no dose of a libido enhancer will induce an erection.

A large number of people are not sufficiently aware of the duality of penile plumbing and neurological wiring. And except for yohimbine, there is no relationships enhancement medication that would work on both components.

Yohimbine does, as the adrenalin which yohimbine displaces from abdominal alpha-2 adrenergic receptors (which, among other things, regulate penile blood flow) reoccur systemically as neurological stimulant.

However, the strong sympathetic impulse caused by systemic adrenaline (in the form of norepinephrine) makes it difficult for the parasympathetic nerve system to take over at the point of orgasm, which, with regular usage of yohimbine, makes for weak ejaculations and orgasms that are no match for the pre-orgasmic excitement. Also, side effects are much worse than with tongkat ali.

But relationships with a firm erection aided by yohimbine is still better than no erection, which normally means: no proper relationships.

Therefore, Viagra (and generic sildenafil citrate), or any other medication that fixes penile plumbing, is a necessity for many men above 40, and for most above 50 or 60.

And only when there are no plumbing problems do other medications (those that work on libido) become relevant.

By and large, there are two groups of pharmaceutical agents that work on libido: those that effect neurotransmitters, and those that target the endocrine (hormonal) system. I say "by and large" because the two systems are intertwined. Drugs that elevate the neurotransmitter dopamine (dopaminergic pharmaceuticals or velvet beans, mucuna pruriens) also suppress the hormone prolactin. Prolactin not only regulates lactation in women but also keeps testosterone in check in men and women. Typically, less prolactin means more testosterone. Furthermore, some hormones can act as neurotransmitters and vice versa; norepinephrine, C8H13NO3, is both a hormone and a neurotransmitter.

The neurotransmitter system reacts much faster than the hormonal system, and you feel this when you take pharmacological agents, or dopaminergic food like velvet beans that act on it. When an effective dosage of any neurotransmitter modifying medications kicks in, you feel it. With most dopaminergics, there is a slight nausea, or at least a desire to lie down. And there is a clear window of opportunity for improved relationships, which usually is the first few hours during which a neurotransmitter drug is active (for apomorphine, this window of opportunity is the shortest; for cabergoline, it is the longest).

When you use neurotransmitters to improve relationships (even L-dopa from mucuna pruriens), you always know that you have taken something.

This is not the case with drugs or herbals like tongkat ali that work on the endocrine system, unless a huge overdose is consumed (for example when women take a testosterone dosage that was formulated for men). Usually, endocrine medications cannot be felt directly. Whether you use growth hormone injections, testosterone cream, Andriol capsules, Proviron, methyltestosterone, anastrozole, or clomiphene, and even with a tongkat ali stack that also incorporates butea superba, mucuna pruriens, and krachai dam, there is no clear onset, and now clear end-of-efficacy time.

In me and many other users, any testosterone-raising medication can cause an outburst of anger (if there is an event that triggers it). The outburst may happen after 2 hours, or after 4, or after 8 or not at all, if nothing happens that would give me reason to get angry. But let me drive a car in a Third World country where people typically do not follow any traffic rules, and not even traffic common sense! If I have taken testosterone-raising medications, I will have a harder time to keep my calm.

The case is similar, but still more erratic with libido. Medications that work on the endocrine system can be extremely sexualizing, but it is very hard to plan this effect. This also applies on a tongkat ali stack with butea superba, mucuna pruriens, and krachai dam.

You can have a relationships schedule when you take yohimbine or dopaminergics. I will reliably have an erection some one-and-one-half hours after ingesting some 10 to 20 mg of yohimbine. I just have to scratch my member, and voila, here we go.

Likewise, when on apomorphine, bromocriptine, cabergoline, or Thai mucuna pruriens, I will feel more excitement during intercourse than when in a sober state. The dopaminergics usually only exert their effect when already at it; at the dosages that I use, they do little for pre-intercourse desire. But Parkinson's patients who use much higher dosages, and do so constantly, often are in a constant state of relationships alert.

Viagra isn't as reliable for erections as yohimbine. When I take Viagra without dopaminergics (including mucuna pruriens) or endocrine agents (including tongkat ali), I may not have the libido impulse to cause a hard erection. I may just have an enlarged but still flaccid organ, and not much drive to pursue intercourse.

Tongkat ali is an endocrine agent, not a vascular modifier. Endocrine agents have a subtle effect on libido. To describe it, I have to reach back a few decades.

I remember the time when I was 12 or 13 years old. Often, before falling asleep, I could daydream along for half an hour or an hour, just imagining relationships scenarios. There was a girl, two or three years my senior, and heavy-bodied, and I imagined I were to abduct her to an old farmhouse, and lock her up, and just observe her through a peephole until she were to pee.

I could just recall this fantasy, night after night, and imagine and re-imagine explicit details, and the excitement wouldn't wane. Night after night, week after week. Never bored.

I could still get lost in masturbation fantasies until the end of my 20's, but in my 30's and 40's, they were no more. As I grew older, relationships moved from between the ears to between the groins. While at a younger age, erections came from imagination, they later required physical sensation.

Enter the tongkat ali.

What I first noticed was that during routine relationships with an established partner, my mind began wondering off to strange ideas. That I was a perverse school headmaster who would punish pupils arriving delayed by squeezing some private parts. Or that I was a cruel Chinese emperor with a harem of 1000 concubines. Those who couldn't bring me to orgasm would be executed. And I really had them work to save their lives. All of that during standard intercourse with a dear lady with whom I otherwise have a rather practical relationship.

Now, this has been going on for weeks. The settings of my fantasies change, but what remains the same is that I really can indulge in them for about half an hour, while at intercourse with a routine relationships partner who is completely absent from the scenario that I imagine.

This is how I feel tongkat ali's impact on my endocrine system. And I love it.

Or rather: this is how I feel a gram of the 1:200 extract from Sumatra Pasak Bumi. I had earlier tried other tongkat ali products, but their effect had been nondescript. Please see my article on tongkat ali dosage for what I consider effective and non-effective amounts.

Because tongkat ali is not a switch-on switch-off relationships stimulant, I believe it is best to take it on a daily basis for about two or three weeks, and then to rest it for about a week. I usually take it some time around noon, as a single 1-gram dosage. Initially I felt a specific hotheadedness after about an hour, but this effect has since subsided.

I cannot say that after 2 hours, or 4 hours, or even after 8 hours I would have great relationships. I cannot willfully switch it on. Great relationships on tongkat ali comes sporadic. Could be later in the day, or even just the next morning.

I always take the tongkat ali with sildenafil citrate (generic Viagra, 50 mg). I don't have the blood vessel stability to go without it. I tried, after another participant in our tongkat ali trial reported that the tongkat ali allows him to go without the Viagra, but when I left it out of my cocktail, my erection clearly wasn't of the usual sildenafil-aided quality.

By all indications, tongkat ali is a hormonal stimulant, and hormonal stimulants, including testosterone, have a weak track record when it comes to aiding erections. Tongkat ali is no exception.

I have a good number of girlfriends. I enjoy variation, and I do not intend to go without it, especially as it has taken me a lot of efforts to arrange everything in a manner that would allow me this lifestyle.

But I believe that the greatest benefit from tongkat ali will be enjoyed by people who are in a rather steady and monogamous relationship. If I have enough imagination, I don't need variation. As a matter of fact, my imaginations blossom brighter with a routine partner who knows my physical preferences and doesn't need verbal attention before or during intercourse. With a routine partner, I just can dive into an ocean of fantasies, without need to resurface for rather practical matters.

On the other hand, when on tongkat ali, the strangeness of a new partner, too, can be turned into relationships excitement. In that case it's not so much the indulging in fantasies but the idea of conscious role play. The roles may not be as weird as my fantasies with a routine partner, but they are still different from normal, sober life.

So, whatever the setting, tongkat ali clearly supports the imaginative part of relationships interaction.


Tongkatali.org Butea superba doping


Butea superba improves athletic performance in humans. This has been well established, even in research by the Thai Doping Control Center at the Mahidol University in Bangkok. See scientific study here:

https://pdfs.semanticscholar.org/12f9/c34f3def0c87f0c968df48d1c6c334e712f9.pdf

Article continues below printscreens:





However, butea superba is not yet on the list of prohibited substances of the World Anti Doping Agency, WADA.

It's not that they wouldn't like to prohibit it. But they don't know how to test for it.

Butea superba affects the whole hypothalamic-pituitary-gonadal axis. Thus, ratios of hormonal metabolites are not skewed as they would be with outright testosterone or anabolic steroids doping.



Cytotoxic effects of the root extracts of Eurycoma longifolia Jack

M. Y. Nurhanan L. P. Azimahtol Hawariah A. Mohd Ilham M. A. Mohd Shukri

Abstract

The methanol, n‐butanol, chloroform and water extracts obtained from the root of Eurycoma longifolia Jack were assayed using methylene blue assay to evaluate its cytotoxic effect against KB, DU‐145, RD, MCF‐7, CaOV‐3, MDBK cell lines. The results showed that all the root extracts except the water extract of E. longifolia produced significant cytotoxic effect on these cell lines. However, no significant cytotoxic effect was detected on MDBK (kidney) normal cell line. 9‐methoxycanthin‐6‐one, an alkaloid, was detected in each extract with different intensities by reversed‐phase high performance liquid chromatography.
