How To Find The Most Potent Tongkat Ali

It is hard to find powerful Tongkat Ali from a trusted source.

It's is even harder to find powerful Tongkat Ali that works every time.

Here's the deal:

Before we found it, we tried it. A lot of it...for over 15 years!

We compared powders to tinctures, and capsules to tablets.
We compared roots from Indonesia and Malaysia and China and Thailand.
We compared the top Tongkat Ali and Longjack brands sold online and in stores.

What did we learn?

It is hard to find powerful Tongkat Ali from a trusted source.

This guide explains everything to know when you are searching for the the most powerful Tongkat Ali on the planet.

The Most Powerful Tongkat Ali

When we started our search for the most powerful Tongkat Ali, we weren't sure where to look.

We made a ton of mistakes. We wasted a ton of money. But we learned where to find the goods and how to avoid the bad stuff.

We should probably get the bad stuff out of the way now...

Our journey has taught us:

  1. GNC and most other retailer brands have a habit of pushing profit more than protecting their customers. 1
  2. The highest-rated Tongkat Ali brands on Amazon are hard to trust. (See #1)
  3. Most “testosterone booster” formulas and "natural" blends online use really low quality and toxic ingredients.
  4. Not enough brands test their Tongkat Ali to prove it is pure, powerful, and actually real Tongkat Ali!

After so much frustration and disappointment, we decided to just go to the source:

Southeast Asia.

Tongkat Ali grows in Southeast Asia

We knew that Tongkat Ali only grew in a small area of the world, so we looked there to find the best.

We narrowed our search down to four countries:

  • Indonesia
  • Malaysia
  • Thailand
  • China

We spoke to growers and collected powder samples from suppliers for testing. Every sample from China that we tested had high levels of heavy metals and contaminants. So we scratched them off our list early.

We devoted the next 12 months testing and trying Tongkat Ali from 5 different growers in two different countries: Indonesia and Malaysia.

By the end, it was clear which Tongkat Ali was the best.

There were three things we focused on to find it.

We call them the 3 Ps:

  1. The Plant
  2. The Power
  3. The Process

Let's start with the plant...

Closeup of a natural eurycoma longifolia plant

The Plant:
Is It Eurycoma, Longjack, or Tongkat Ali?

Actually, all three names refer to the same plant.

Tongkat Ali and Longjack are just the common names for the eurycoma longifolia plant.

It is a skinny tree that grows in the lush rain forests of Southeast Asia, mainly Indonesia and Malaysia.

There are four “official” species of Tongkat Ali, but many include a fifth, called Jackiopsis ornata or Red Tongkat Ali. However, most researchers and even the Journal of Applied Science do not consider it to be a member of the family.

The Five Species of Tongkat Ali

1. Eurycoma Longifolia Jack

This is often called Longjack. It is the most studied Tongkat Ali species with the best results, which is why we use it in our supplements...and because it works for us.

2. Polyathia bullata

This is known as Black Tongkat Ali but also has King or Gorilla in its names. It is dark brown, almost black, on the outside and white or very light tan on the inside. It is used in extracts but not as much as eurycoma longifolia jack. Probably because there is very little research on this species.

3. Eurycoma apiculata

This is a super rare species that is barely found outside of Southeast Asia. We have heard it is far weaker than eurycoma longjack, so we have ignored it in our quest for the most potent species.

4. Goniothalamus sp

This Tongkat Ali species is similar to Eurycoma apiculata, with limited use or studies about it.

5. Jackiopsis ornata

Many will say this is not a species of Tongkat Ali but it’s becoming more popular in Malaysia. It is also known as Merah or Red Tongkat Ali because it has a pinkish-red color after it is harvested. It tastes similar to ginseng and is less bitter than eurycoma longifolia jack.

Right now, Eurycoma Longifolia jack is the best Tongkat Ali to use because it is the most sustainable and is proving to be the most effective.

Organic Tongkat Ali From Indonesia

We also think it’s important to choose Indonesian Tongkat Ali only.

Here’s why:

Research by the University of Malaysia shows that almost half of the Tongkat Ali from Malaysia had levels of mercury and arsenic that were not safe to consume. 2

Heavy metals naturally occur in most soils but these these numbers are very high.

These heavy metal levels can lead to serious health problems.

Clean soils matter when you want the roots.

But getting to the "root of the matter" is not an easy job. Extracting Tongkat Ali roots can take hours.

Imagine driving for over an hour in an old farm truck, deep in the mountainous jungles of Southeast Asia, until you reach a clearing full of tall, skinny trees.

They first look like thin palm trees or very old tree ferns. Some are over 40 feet high.

Tongkat Ali plants look like trees with berries

It takes time and patience to extract the plants from the ground. For starters, the roots grow very deep in dense, forest soil. Only after the root is clearly exposed on all sides, can it be cleanly pulled out of the ground.

It’s a backbreaking process.

Extracting Tongkat Ali Roots is backbreaking

But there’s a big reason why this root has been pursued and used by the local people for hundreds of years.

It’s powerful.

The Power: Eurycoma Longifolia Jack + Tongkat Ali + Longjack

Tongkat Ali has been used for hundreds of years to help men and women.

Most consider it a strong aphrodisiac that helps with erectile dysfunction and improves physical strength.

But its power goes beyond that.

New research is proving that Tongkat Ali:

  • Boosts testosterone
  • Burns fat and adds muscle
  • Powers you with extra energy
  • Gets you horny and up for sex

Check this out...

Tongkat Ali Helps Testosterone

Most of Tongkat Ali’s benefits are directly related to a boost in testosterone.

This is a good thing.

Testosterone is vital for motivation and confidence, as well as the metabolism of fat, carbohydrates and proteins...ENERGY! 3

Normal testosterone levels in men generally range between 300 ng/dL and 1050 ng/dL.

However, most men experience a drop in testosterone every year starting around their 40th birthday.

In fact:

40% of men over 45 years old have testosterone that is too low.4

And they don’t even know it.

Chart showing the natural testosterone decline in men
  • Low testosterone can cause low energy.
  • Low testosterone can cause low patience.
  • Low testosterone can cause you to lose focus.
  • Low testosterone can cause you to forget things.

Even worse:

While your mood and memory are slipping, your body is too.

Low testosterone can cause you to lose muscle but gain weight as muscle tone is replaced with fat and flabby skin.

The worst part:

You start to feel little to no sex drive and have weaker erections.

5 Early Symptoms of Low Testosterone

  • Softer Erections
  • Lower Sex Drive
  • More Body Fat
  • Less Muscle Tone
  • Feeling Tired - ALL THE TIME

Some men choose testosterone replacement therapy (TRT) to get a testosterone boost. This also helps treat a condition known as testosterone deficiency syndrome (TDS).

TRT is good at giving them higher levels of testosterone, but the small positive changes can lead to big negative side effects.

Testosterone replacement treatments, like testosterone creams, patches, and injections, can slow down your body’s natural testosterone production.

These same testosterone prescriptions can also boost your body’s testosterone levels too high. This can lead to estrogen rebound and the extra testosterone gets converted into estrogen.

Too much estrogen leads to belly fat and man boobs.


If testosterone declines naturally, then why not choose a natural solution to the problem?

Tongkat Ali is one of the most popular natural testosterone boosters because it works. Well, the most powerful Tongkat Ali works.

Not all testosterone boosters do the same thing.

Many supplements raise your testosterone levels but not your free testosterone levels.

Free testosterone floats freely through the body, unattached to proteins, making it more available for your body to use. Free testosterone can provide you with even more strength, more stamina, and less stress.

To better understand how Tongkat Ali helps to naturally raise testosterone, it's important to understand how testosterone is produced in the body.

Science is always evolving and growing. We are still learning new things about hormones, especially estrogen and testosterone.

Here’s what we know:

Testosterone is regulated by a process known as the Hypothalamic Pituitary Gonadal axis. The hypothalamus is the area in the brain that directs hormones in the body.

When testosterone levels are low, a chain reaction occurs in the body:


Step 1
The hypothalamus secretes Gonadotrophin-Releasing Hormone better known as GnRH.

Step 2
GnRH triggers the pituitary gland to release a luteinizing hormone into your blood, better known as LH.

Step 3
LH moves through the bloodstream to the testicles where it stimulates Leydig cells to produce testosterone and release it into the bloodstream.

You're probably wondering:

How does a skinny tree make testosterone like this?

Well, it doesn’t.

Your body does.


Tongkat Ali helps your body make testosterone when it slows down.

Remember Step 1 of testosterone production?

The hypothalamus secretes GnRH

Research shows that Tongkat Ali can stimulate the hypothalamus gland to release more GnRH, which kick starts the natural process of testosterone production.5

This is the starting point for testosterone.

Testosterone creams, patches, gels, and injections can cut corners.

These testosterone treatments often replace your natural hormones with synthetic versions, that simply trick the Leydig cells into producing more testosterone.

It's a fast solution.

BUT it skips the first 3 steps of natural testosterone production!

And it can throw your body out of balance.

Even worse:

After taking testosterone for too long, the testes can start to rely on it too much and slow down natural testosterone production.

This can lead to serious medical conditions, like diabetes and cancer, but usually it usually starts with more belly fat and less boners.

In other words:

Stop taking it. Start making it.


Tongkat Ali is not a testosterone replacement.

It activates the body’s ability to make testosterone.

This is why many researchers believe Tongkat Ali can be a healthier alternative to testosterone replacement therapy. 6

This healthy boost of natural testosterone has many benefits.

Let’s start with the best one...

Tongkat Ali Improves Sex

The most common side effect of low testosterone is a shrinking desire for sex.

Sometimes just the idea of having sex sounds exhausting.

Sometimes you are feeling too depressed, stressed, distracted or anxious to get in the mood.

Sometimes the boner is missing.

Erectile Dysfunction can be a serious consequence of low testosterone.

Tongkat Ali can help.

Research shows that Tongkat Ali can improve: 7

  • Sexual desire
  • Erectile function
  • Sexual satisfaction

Tongkat Ali can be a natural solution for Erectile Dysfunction, or ED, for some people.

ED can lead to worse problems when it is ignored:

  • ED can cause anxiety.
  • ED can lead to depression.
  • ED can ruin your intimate relationship(s).

This all just adds up to a pile of extra stress that you don't need in your life.

Tongkat Ali Lowers Stress

Cortisol is your stress hormone.

When you feel stress, your adrenal glands release cortisol.

Cortisol gives you quick energy and sharpens mental focus.

It’s great for escaping danger. As long as that danger isn’t happening every day.

Constant cortisol production, caused by chronic stress, can lead to adrenal fatigue and serious health problems.

Tongkat Ali has shown it can help lower cortisol levels and stress.

One study in the Journal of the International Society of Sports Nutrition determined Tongkat Ali to be a safe and effective stress reliever. After 4 weeks of cycled use, 63 participants had lowered their cortisol levels, increased their testosterone levels, and claimed to feel less anger or tension. 8

So … Tongkat Ali can help you relax AND improve your sex life.

And there's even more it can do...

Tongkat Ali Burns Fat And Adds Muscle

Aromatase is an enzyme responsible for the biosynthesis of estrogens.

The more aromatase your body makes, the more fat you can gain.

Some sports nutrition doctors believe Tongkat Ali helps slow down aromatase production, so the body is able to burn fat more efficiently.

This would also help create a more natural hormonal state for increasing muscle.

The increased testosterone running through the body can also improve the function of natural Human Growth Hormone, or HGH.

This combination of low aromatase and higher HGH helps to create an anabolic environment in the body for increasing muscle mass.

A study published in Phytotherapy Research found that Tongkat Ali may help boost muscular strength in older individuals whose strength has naturally declined due to their age. 9

It’s not just men over 40 and bodybuilders who take Tongkat Ali.

Endurance athletes use Tongkat Ali too...

Tongkat Ali Gives You A Natural Energy Boost

Research has shown that Tongkat Ali improves energy and endurance by increasing ATP production.

ATP is the energy in your body. During heavy exercise, you use up ATP faster than you can replace it. This leads to fatigue.

So if you increase your ATP, you increase your energy and endurance.

A placebo-controlled human study published in the Journal of International Society of Sports Nutrition showed that Tongkat Ali can increase ATP by creating a positive anabolic state that builds up muscle strength while suppressing a catabolic state when muscles break down to exhaustion. 10

The Biggest Side Effect Of Tongkat Ali

This may all sound good but there is one bad thing about pure Tongkat Ali:

It tastes horrible. The purest Tongkat Ali root powder is very bitter.

In fact, Tongkat Ali supplements that do not taste bitter are probably not authentic Tongkat Ali root.

Tongkat Ali roots are bitter because of quassinoids.

Quassinoids hold the real power in Tongkat Ali.

The Real Power of Tongkat Ali

Quassinoids are one of the most bitter chemicals found in nature, but they also hold some of the most potent medicinal properties.

Over 150 quassinoids have been identified to hold anti-inflammatory, anti-viral, anti-malarial and anti-proliferative effects on various tumor cell types.11

Eurycomanone is the most powerful bioactive quassinoid in Tongkat Ali.

New research is showing that eurycomanone may be what’s behind all of the health benefits of Tongkat Ali. Even more important, the most effective Tongkat Ali root samples have had the highest eurycomanone levels. 12


The higher the eurycomanone, the more effective the Tongkat Ali.

The Process: Tongkat Ali Root Extract

Most Tongkat Ali brands never measure their eurycomanone level.

This is probably why so many of the highly-rated Tongkat Ali brands were not effective for us. We expect all of them had low eurycomanone levels, less than 3%.


How do you get Tongkat Ali with high eurycomanone levels?


Let's explain…

All eurycoma longifolia plants grow differently.

Different soil, different sunlight, different water, and different air can cause the plants to vary in size and strength. Even trees next to one another will have different eurycomanone levels.

Consistency is impossible.

Most Tongkat Ali and Longjack brands don't think of this when they add Tongkat Ali root powder to their products.

They go the traditional route...

Traditional Tongkat Ali Root Extract

Traditional extract measures its strength by the amount of root used to produce a single gram of extract.

So when Tongkat Ali brands use ratios like 50:1, 100:1, or 200:1, this means it takes 50, 100, or 200 kg of roots to make 1 kg of powdered extract.

These ratios do not guarantee any level of quality or potency.

The numbers trick you into thinking the higher the number, the stronger the product. But it really just tells you how much of the plant matter was removed during the extraction process.

The traditional method is really ineffective because the active ingredients of Tongkat Ali root extract vary depending on the age and quality of the root that is used.

So you don't really know what you are getting.

Standardized Tongkat Ali root extract is different...

Standardized Tongkat Ali Root Extract

Standardized root extract guarantees an equal amount of eurycomanone - the most important active ingredient - throughout the final powder.

Pile of Longjack Tongkat Ali Root Extract powder

Eurycomanone levels in Tongkat Ali are accurately measured and standardized by a lab technique called High-Performance Liquid Chromatography, or HPLC.

The best part about this process is the consistency. HPLC offers a the same, high-quality standardized Tongkat Ali root extract powder every time, regardless how much root is used.

Here's how HPLC works:

  1. Tongkat Ali roots are peeled and cleaned.
  2. The clean roots are heated in liquid.
  3. The roots are reduced to mush and removed.
  4. The last of the liquid is evaporated until only the root extract remains.
  5. The root extract is then freeze dried into a fine powder.

Standardized extracts can be measured and closely monitored during the liquid phase so the finished product has the desired potency.

Standardized Tongkat Ali Root Extract can be montiored to increase strength

HPLC also ensures the same potency can be repeated, batch after batch.

Consistency matters when you expect results every time.

This is why most research on eurycoma longifolia jack, or Tongkat Ali or Longjack, uses STANDARDIZED ROOT EXTRACT.

Only STANDARDIZED Tongkat Ali has been proven to help:

  • Energy
  • Strength
  • Endurance
  • Muscle Mass
  • Sexual Health
