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 Metaphysics provides hope and focus


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


For believers, and even for those who are just sympathizers, Kreutz Metaphysics gives hope, focus, guidance, goals, and a tremendous amount of energy. It does so if the perspective is the reminder of one’s conventional, physical life, and if the perspective is the existence of one’s soul after a person’s physical death.

For the reminder of one’s physical life, the focus is the desire for optimal sexual experience. Even in the most miserable conditions, illness or incarceration, we fight to stay alive because wee want to experience at least once more, or even just once more, the soul-building bliss of an all-engulfing orgasm.

In difficult times, we are immune to depression because we know what we are living for. We fight along, and we hope along, for never mind how hard life may be, there always is a reason, a good reason indeed, to struggle on. No, not for our children, and certainly not for mankind overall, and not the future of planet earth. Also not in order to please any almighty, who isn’t just invisible but whose existence is unreasonable, much more unreasonable than the concept of a soul generated by orgasmic power.

We struggle on in the most complicated of circumstances because we long for, hope for, work for the best sex of a lifetime.

Adherents to Kreutz Metaphysics never give up.


Buying tongkat ali


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


So you have decided to try some tongkat ali. But before buying, some important decisions are to be made.

Do you want tongkat ali roots, or do you want tongkat ali extract?

If you buy roots, the cost of shipping will be much higher than the roots themselves.

Brewing your own tea will also be time-consuming.

If you want extract, you first have to decide whether you want genuine tongkat ali or fake tongkat ali?

Unfortunately, more than 90 percent of all tongkat ali extract on the market is simply fake.

There are two kinds of fakes:

1. those that are any root powder or plant, mostly tribulus terrestris. These simply have no effect at all.

2. powders laced with sildenafil analogues, often at high dosages. These have an effect, just like Viagra has. But it's not the hormonal effect of tongkat ali. It's an effect of sildenafil, tadalafil, or vardenafil. And unfortunately, these fakes regularly kill users.

xxxxxxxxxx

Tongkat ali is a root, and as such, it consists mostly of cellulose. Cellulose is not a pharmacologically active substance. The pharmacologically active ingredients only form a very small part of the root.

The raw root, whether powdered or chipped, is not fit for human consumption. This is not just the case because humans cannot digest cellulose but also because the raw root often is infested with fungi and bacteria, some of which are harmful. This is absolutely normal for anything that grows underground. Is there anything humans would pull out of the soil and consume uncooked?

Raw root powder is commonly sold in Malaysia as well as in the US, both in brick-and-mortar shops and by Internet retailers.

There is, of course, nothing wrong with root powder or chipped root, as long as you know how to handle it.

If you do not buy a ready-made extract, you have to prepare the root powder or chipped root as your own extract. This can be a liquid extract or a dry one. If you prepare a liquid extract, you will have to consume a lot of fluid to get a proper dosage. Producing your own dry extract will take a lot of time.

Root powder in capsules is nonsense because one should not ingest raw tongkat ali root, even not if it is packaged in gelatin capsules. The most likely effect of ingesting raw root powder is diarrhea, caused by salmonella bacteria. And if you are unlucky, you get a strain that causes typhoid fever.

Tongkat ali is so bitter, and tastes so lousy, that the only way one can ingest a proper dosage is to get it down as quickly as possible. Capsules of dried tongkat ali extract are a good solution because extract is concentrated, and you can swallow the tongkat ali without tasting it.

The only problem with dried extract in capsules is that you are easily cheated. It is very difficult to check yourself whether you actually get tongkat ali extract, or just tongkat ali root powder, or something else altogether.

Tongkat ali root has to be boiled, and before being boiled. Use about half a liter of water for 50 gram of root powder or chipped root. 50 gram of root powder or chipped root will yield about 2 normal dosages, or a single dosage for an experienced user or a bodybuilding athlete.

I know what I’m talking about because I did make my own extract. I did so because I am a suspicious character, and so that I could write about it.

I used 500 gram of chipped root, soaked in 5 liter of water for 24 hours. I brought the whole thing to a boil, and then filtered the water. I then left the 5 liters of water for almost 2 days on an electric stove with heat control (about 50 centigrade) until I got a thick sap. I further heated the sap in an electric oven (about 40 centigrade) and then got a rather hard crust. Working this crust through an electric coffee mill, I ended up with about 10 gram of powdered extract. Which means: an extract of the strength 1:50. 10 dosages out of 500 gram.

I discussed this extraction process with two German pharmacists and the assistants of a plant analytical laboratory of a university. They all assured me that mine has been a proper extraction process.

There isn’t much technology to preparing water-based extracts. The solvent has to be water, and just water, otherwise the result would not be an aqueous (water) extract. In proper extracting facilities, they have integrated machines that speed up the evaporation by doing it under high pressure, or by other means. Some companies that sell such evaporating equipment have patents on these machines.

But if a website claims that they have patented the extraction by water of tongkat ali, then that’s bulls. They just want you to believe that their extract is special (so that you won’t buy somewhere else), and that it justifies an inflated price.

Tongkat ali has been researched well, though not in full. But one thing is certain: the traditional use is as an aqueous extract (extraction by water, as in tea or coffee), and that way, it has been used in Southeast Asia for hundreds of years.

Other extraction possibilities would be by ethanol (alcohol) or chloroform, and a plethora of other chemical solvents. But such extracts have only been tested recently, and only one thing is clear: their LD50 values are much worse than those for aqueous extract. I would not experiment with tongkat ali extracts in which the solvent has been anything but water.

Extract strength is another critical topic. I know from my own experiments that 100 grams of root yield a dried extract of 2 gram. So, 1:50 seems to be genuine strength of an aqueous extract.

Of course, 1:100 sounds much sexier. But who is to check on such claims? Even if a new trader should decide to proclaim that his extract is 1:1000, who is going to examine whether the claim is true?

A 1:100 extract, or one that is proclaimed to be 1:1000, doesn’t necessarily contain more active ingredients. In order to turn a 1:50 extract into one that is 1:100, I really just have to discard half of the 1:50 extract. I can do so by passing it through a smaller mesh, which will just remove the coarser part of the ground crust I got from drying the aqueous extract.

Thus, turning a 1:50 extract into a 1:100 extract means just that they sell half the extract, probably for double the price. It says NOTHING about the efficacy of the extract.

Furthermore, there are justified suspicions that what is sold as 1:100 extract may only be root powder. I have seen documents on the FDA website (www.fda.gov) that show that people marketing 1:100 extract capsules have just applied for a registration of tongkat ali powder in capsule form, not of extract in capsules. To see these documents on www.fda.gov, please use their search engine and enter the search term “eurycoma”. The scientific, Latin name of tongkat ali is eurycoma longifolia, and official documents deal with the plant under this name. Do not search for “tongkat ali”, as this will not get you to the FDA correspondence about the product which is sold as 1:100. A search for the combined name, “eurycoma longifolia”, doesn’t seem to work well on the FDA site. It is best to just search for “eurycoma” only.

I also cannot recommend purchasing from Internet spam sites.

Their expertise is not tongkat ali but Internet marketing. They know how to force their own site(s) to the top of search engine rankings, and then hunt sales commissions from the manufacturers whose products they promote. This is why the information they provide is not their own but just taken from other sites (like mine) and then more or less reworded.

I believe that it makes sense to buy tongkat ali or tongkat ali extract at the origin. From a company whose product is tongkat ali, and not from a company whose product is Internet marketing, and who will sell any merchandise for which they can get a high search engine ranking.



Tongkatali.org's integrated male relationships success


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


Tongkatali.org provides an integrated service for male success, with a focus on East and Southeast Asia. Male success has a lot to do with male sexual success. Tongkatali.org sells sexuality-enhancing herbals with a proven scientific track record. This is our core operation.

But apart from that, Tongkatali.org is dedicated to the sexual success of our customers on a much wider scope.

Tongkatali.org, for example, offers consultation to customers on dental work and cosmetic surgery in Southeast Asia. This service is free for our customers, and can save them a lot of money and protect them from some bad experiences as well.

We often refer to our customers as members. For more than a decade, we have run formal memberships via sergekreutz.com. There were sexual function memberships and sexual opportunities memberships, both priced separately at 250 US dollars each. We have discontinued these, because there simply are too many phony consultation services around which use the same language.

As it stands now, anything related to information is free for members of Tongkatali.org (membership is automatic for those with an order history of 1000 US dollars or more for tangible items, mostly sexuality-enhancing herbals.

Some men are in lifelong exclusive sexual relationships. We respect and congratulate customers to whom this applies.

Most men are not made of such timber. Most men, and a large number of our members, have a profound interest in sexual variety.

For these men, if they are Westerners, East Asia has a lot to offer. Not only is the East Asian approach to physical relationships much more down-to-earth and open to negotiations. The age of men is also of much less relevance, if of any.

Tongkatali.org and Serge Kreutz started out in the early 1980s (around 40 years ago!) with travel guides on Southeast Asia. Unlike standard travel guides, these travel guides already did cover physical relationships. Travel guides nowadays never touch this topic.

Little has changed in Asia in 40 years. Of course, there are better roads, and now there is Internet. And immigration has become more complicated. But the mentality of the people up-country has changed amazingly little.

For members, Tongkatali.org provides free lifestyle advice, tailored for Western men considering moving to East Asia to achieve better physical relationships.

There is more. Tongkatali.org also trades domain names, and our members can rent unique motorhomes designed for Southeast Asian weather and infrastructure. These motorhomes are suited for couples or families going for extended holidays in Southeast Asia, and also for unattached men roaming isolated areas for physical adventures. Mind you: in Asia, the further away you get from modern, urban centers, the better your relationships will be.

Yohimbe combined with bromocriptine or deprenyl


By Serge Kreutz
Follow Serge on Twitter@serge_kreutz


I have tried combining yohimbe with deprenyl and/or sildenafil citrate, as well as with arginine, and occasionally with bromocriptine. I tried these combinations over several weeks (though not every day).

Yohimbe plus bromocriptine

Bromocriptine in itself can have an effect on desire. However, with small doses, the effect wears off after just a few uses – and with larger dosages, nausea will eliminate any pro-relationships effect.

While nausea can be avoided when taking bromocriptine in very small dosages alone or with sildenafil citrate, the trick does not work when combining bromocriptine with yohimbe. When on yohimbe, I have never managed to avoid the nausea caused by adding bromocriptine. If nausea occurs when using bromocriptine alone, I can sometimes escape the discomfort by going to sleep. After ingesting bromocriptine with yohimbe I may get to sleep more easily than on yohimbe alone, but sleep quality is nowhere near what it would be without the yohimbe.

I do not recommend combining yohimbe with bromocriptine. And I do not recommend either alone. Both substances mess up relationships quality, and especially bromocriptine does damage to relationships parameters. This is in contrast to tongkat ali which improves long-term relationships health.

Yohimbe plus deprenyl

I have also tried deprenyl (selegeline, Jumex) with yohimbe. Deprenyl is a MAO inhibitor, and I had read that MAO inhibitors don’t go well with yohimbe, so I was careful with the dosages. I had previously tried deprenyl alone, and found it to have an amphetamine-like effect at dosages of more than 2.5 milligrams (half a standard Jumex tablet). I don’t feel the amphetamine-like effect anymore with up to 5 milligrams. But for me, deprenyl also detracts from the yohimbe when combined with it.

I have always found deprenyl’s pro-relationships effects overrated. It’s a dopaminergic substance, and dopamine is, to a certain extent, responsible for relationships desire. But dopamine overstimulation strongly interferes with erectile function and leads to a (reversible) shrinkage of the male organ. That’s why cocaine, and amphetamines may make you horny, but also make erections and orgasms more difficult to achieve.

Deprenyl is not as bad as amphetamine and methamphetamine in making erections more difficult. It may even be that a 25-year-old would not feel any erectile impediment. But for a man of about 50, the anti-erection effect is stronger than the pro-libido effect, unless there is a clear dopamine deficit (as with Parkinson’s patients).

One can counterbalance the anti-erection effect of deprenyl with a phosphodiesterase inhibitor. In fact, I have been told that drug users now regularly mix cocaine with sildenafil citrate to avoid shrinkage.

But why combine yohimbe and deprenyl when this is no better than yohimbe alone, and definitely worse than the combination of yohimbe with sildenafil citrate?

As deprenyl is an MAO inhibitor, it may possibly aggravate the negative side effects of yohimbe. Yohimbine is an alpha-2-receptor blocker; it frees systemic adrenaline and noradrenaline. Adrenaline and noradrenaline (epinephrine and norepinephrine) function as hormones and as neurotransmitters. The adrenaline and noradrenaline displaced by the yohimbe from alpha-2-receptors lead to mental agitation as well as increased heart rate.

This effect is countered by the enzyme monoamine oxidase (MAO), which breaks down adrenaline and noradrenaline, leading to relaxation after states of agitation. MAO inhibitors interfere with monoamine oxidase’s capability to deaminate and destroy adrenaline and noradrenaline. In combination with yohimbe, this means that the agitated state lasts until the yohimbine has cleared from the alpha-2-receptors. With unimpaired monoamine oxidase, the agitation caused by the displacement of adrenaline from alpha-2-receptors should be countered by the breakdown of free adrenaline and noradrenaline.

Combining deprenyl with yohimbe will likely prolong the negative side effects of yohimbe, such as heart palpitation, nervousness, and sleeplessness, while doing little or nothing to enhance the pro-relationships effects.

What we would really like with yohimbe is increased MAO activity, not diminished MAO activity, so we could go to sleep after having enjoyed yohimbe’s pro-relationships effects. Therefore, we don’t want deprenyl, but some sort of ‘anti-deprenyl’ .
