What is Tongkat Ali Extract?

Tongkat ali extract

If you haven’t heard of Tongkat Ali extract, you are probably like what the *$#% is this guy talking about. A powerful herb surrounded by mysticism? Sorry for being dramatic, but I had to capture your interest.

Tongkat Ali is really not that much of a mystery, the only confusion comes from the mass marketing that surrounds it. With scientific advances, we now know what Tongkat Ali truly does and how to use it for whatever benefit you want.

So what is it?

Tongkat Ali is a Southeast Asian herb that grows in the jungles of Malaysia, Thailand & Indonesia. It is commonly known as Tongkat Ali, Tung Saw & Pasak Bumi, depending on which country you are in (respectively). It is also known to some as herbal Viagra, but we’ll get into that a little bit later.

For centuries, this root has been used by natives as a potent aphrodisiac, a health tonic, and an energy enhancer. And now, it is available to you to use at your discretion. So what does this magic herb do exactly?

Let’s find out.

Uses & health benefits of Tongkat Ali Extract

Usage of tongkat ali extract

The list of Tongkat Ali’s health benefits is a long one. But we are going to go through everything.

1) Increase in testosterone levels

Listen closely because we’re about to delve into some serious man talk. And no, we’re not discussing your favorite IPA or the latest NFL scores – we’re chatting about something that’s really going to spice up your life: Tongkat Ali extract. 👌💪

So, let’s set the stage here. Tongkat Ali, also known as Eurycoma longifolia Jack, is like the Rolls Royce of testosterone boosters. It’s not your run-of-the-mill, over-the-counter synthetic testosterone booster. Oh no, this stuff is the real deal! It’s like nature’s own little secret weapon for us dudes, especially us middle-aged male rats wanting to stay in the game.

Here’s the lowdown:

most testosterone boosters are like that dodgy car salesman who sells you a lemon. Sure, they’ll pump up your Leydig cells (those are the cells that make testosterone, by the way) to produce more testosterone levels, but eventually, these cells will tire out and stop producing. But Eurycoma longifolia Jack is not about burning out your engine. Instead, it’s about fine-tuning what you’ve already got. It’s more of a testosterone “optimization” system. 🚀
Sean Russell
Founder, CEO | Menprovement

Stay with me, this is where it gets a bit sciencey. 🧪🧬 Your body has this hormone, sex hormone-binding globulin (SHGB), that’s like the clingy partner of your testosterone—it binds to it and won’t let go, making your testosterone levels essentially useless. But here’s where our star player, Tongkat Ali Supplement, comes into the game.

Herbolab tongkat ali

eurycoma longifolia Jack is like the best wingman you could ask for. It steps in, breaks up this unhappy union, and lowers your levels of SHGB.

In simple terms, this means that your body gets to use more of its naturally occurring free testosterone levels. So, the longer you’re taking this supplement, the more free testosterone you’ve got in your system. That’s what we call winning! 🏆

And, unlike other testosterone boosters, you don’t have to worry about the infamous rebound effect with Eurycoma longifolia Jack, which means your body keeps producing its sex hormones as per usual. This stuff is like a marathon runner, it’s in it for the long haul, it’s steady, reliable and only gets better over time.

The gist of it is this: Tongkat Ali supplement helps control your stress hormones and up the ante on your testosterone levels in a way that’s natural, safe, and effective. And who wouldn’t want that, right?

Just remember, guys, knowledge is power. So, take what you’ve learned here, harness the health benefits of Eurycoma longifolia, and let’s keep leveling up. 👊🔝


a) Here are some AST testosterone tests after 4 weeks and 8 weeks of being on Tongkat Ali. Compare these to normal testosterone levels here.

b) Here is another study from 2012 out of Malaysia on seventy-six men with hypogonadism. Before the trial, 35% percent of the men had abnormally low testosterone levels. After the trial, 90% of the men’s testosterone levels had jumped to the normal range.

2) Increase in Libido

One of the most popular reasons guys buy Tongkat Ali extract is for its proven strength as a natural aphrodisiac. This has been so commonly proven over and over, predominately on animals.

“Tongkat Ali Extract turns lame male rats into sex-crazed beasts.”

Yes, you read correctly. In numerous studies, Tongkat Ali extract turned old lame rats into sex-crazed animals, often licking their own genitalia in need of release.


a) In this study middle-aged retired breeder mice were dosed with Tongkat Ali extract for 10 days. The group being dosed with the Tongkat Ali extract showed a large increase in mounting frequency with female rats. Also, the rats displayed an increase in licking and general genital sniffing towards the female rats. Along with that, the rats not dosed were noted to be exploring the cage naturally while the rats who were dosed were constantly hanging around the female rats.

Sean’s note:

There are a lot of these rat studies, I am not going to bore you with them. You can find them all at the bottom of the page.

Cool, but does it work on humans?

You bet.

Here is an account of a 76-year-old man’s experience with the herb. He started it due to a lack of sexual desire with his wife. After 10 days on the herb, he describes his experience as:

“Sexual fantasies all day long, semi-erection, fullness in testicles. Wanted sex in the worst way.”

3) Increase in Sperm Count And Quality

Sperm cells

Increased sperm quality is one of the most noted and desirable health benefits of Tongkat Ali extract. In a world where most modern luxuries are against your sperm count (cell phones, GMOs, etc.) it’s good to know Tongkat Ali has got your back.

Herbolab tongkat ali


A study of 75 men who consumed Tongkat Ali extract every day experienced significant improvements in sperm count and quality that lasted for months after the study ended. In fact, follow-up semen analyses in these patients showed significant improvement in all semen parameters.

4) More Powerful Ejaculations

Along with having better sperm, Tongkat Ali extract will actually allow you to shoot it stronger and farther.

In the end, one test subject states:

“As ejaculatory function has been the most difficult to enhance over many years, I was, of course, quite pleasantly surprised when I found out that on 1 gram of 1:50 Tongkat Ali extract obtained from Sumatra Pasak Bumi, I was able to produce shooting ejaculations. This, I consider quite an achievement.”

The stuff we link to below is the same stuff this test subject used.

Herbolab tongkat ali

5) Better Sex

Better sex? How?

While Tongkat Ali won’t turn you into a porn star, it will help you come close. Users commonly notice a reduced refractory period means more back-to-back sessions.

Others have reported fewer problems with erectile dysfunction, due to Tongkat Ali Extract and some men have even reported the refractory period being so low they can achieve multiple orgasms.

With harder erections,  a higher libido, more sperm, and more firing power – it’s hard not to have a better sex life.
Sean Russell
CEO, Founder | Menprovement

6) Increased Fertility

It is also common sense that with a higher libido, better sperm, and more shooting power – you are going to have an increased chance of infertility.

Most of you guys are probably not buying Tongkat Ali extract with the goal of pregnancy. But if you are, you’re in luck!

Herbolab tongkat ali


The same study about the semen volume that we talked about above resulted in 15% of the participants reporting new pregnancies. This is staggering if you think about it. But it makes sense, being that better sperm, more concentration, and higher mobility is a key factor that impacts male fertility.


Be careful with this stuff – If you are not ready for children, invest in some protection before your hormones are raging.

7) Male Enhancement (Penis Enlargement)

I bet this headline got you excited. Well, it should. Penis enlargement is a cool thing. There have been some claims floating around the internet that Tongkat Ali can actually increase the size of your penis and testicles.

While there is no doubt that Tongkat Ali extract will increase your libido, volumize your sperm and increase the power of your ejaculations – there is not too much to prove that it can actually increase the size of your dick. But – there is hope.

In reality, it is increased stimulation in the Leydig Cells in pubescent boys which sparks penis growth. Tongkat Ali has been shown to activate these same Leydig Cells which in turn increase testosterone levels.

Does this translate to penis growth?

It just may. The evidence below shows the promise of the Tongkat Ali extracts working in terms of penis enlargement. Even if it doesn’t work miracles, it definitely can be a great addition to any PE routine.


Here is a study on rats where dosing of Tongkat Ali actually did produce a 50% increase in the size of the levator ani muscle.

There are no human studies, but I found some great articles where guys claim to have an increase in size from Tongkat Ali alone.

8) Mood & well-being enhancement

Okay, so now that we are done with the staggering sexual health benefits of the Tongkat Ali extract, we can move on to the other stuff.

First is that Tongkat Ali extract has been proven to provide mood enhancement, reduce stress hormones and boost in well-being. (Be careful though – too much can cause insomnia and agitation – see side effects section below)


In a study on Tongkat Ali’s effect on stress hormones and psychological mood state in moderately stressed subjects, the Tongkat Ali group was found to have an 11% decrease in tension, a 12% decrease in anger, and a 15% decrease in confusion.

It is also important to note that in this study about the assesses stress hormones, the same group was recorded to have reduced (stress hormone) cortisol exposure (−16%) and increased testosterone levels (+37%). More test-boosting evidence.

9) Muscle Gain and Fat Loss

For the athletes, if you are not interested in the sex part, which you probably still are, Eurycoma longifolia jack also has been shown to increase muscle and boost fat loss.

It is common sense that when your cortisol drops and your testosterone rises, you are going to shred fat and lean up. You are putting your body in the perfect muscle-man homeostasis.

Also, this boost in testosterone and reduction in cortisol will benefit anyone who is under intense stress. Essentially anyone who is training their ass off.

By the way, if you are looking to get some fat off, get some pills.

Herbolab tongkat ali


The British Journal of Sports Medicine reported that in a double-blind placebo-controlled scientific trial, the use of Tongkat Ali extracts resulted in a 5% increase in lean body mass in the user group, while no significant changes were observed in the placebo group. 5% of lean muscle mass in only 5 weeks is huge.

That can equate to 20% in just 20 weeks.

Among other interesting facts, the journal article states:

“The mean arm circumference of the treatment group increased significantly by 1.8 cm after the supplementation, from 30.87 (1.88) to 32.67 (1.96) cm (p = 0.011), but there was no significant increase in the placebo group.”

The boost in vigor and hormone support may be just what you need to meet your fitness goals.

10) Athletic Performance

Black athletes sprinting

I am inclined to say that eurycoma longifolia jack will help athletic performance. The increase in tests and the energy boost will no doubt make you a beast on the field.

But I also want to say that it is known to increase your heart rate and body temperature, so it may not be the best combo for people doing intense aerobic training on a hot day.

It is great for weightlifting and working out, no doubt.

But I wouldn’t pop it before your next half marathon. You would probably be fine! There has been nothing reported. But I like to edge on the safe side.

And the manliest herb on the planet award goes to..! Seriously this stuff crushes me. But before you go run out and buy it, keep reading because there is a lot of stuff you need to know. Plus, we will let you know where we get ours so you Don’t get duped.

Proper Use and Dosage of Eurycoma Longifolia Extract

Sexy doctor talking to a man

It is important to know how to properly take eurycoma longifolia before you start. It’s not like other supplements where you can just pop one in every day for 3 months. Well, you can, but it won’t work as well.

You Have to Cycle it

To get the most out of your investment, it is recommended that you cycle it and run a break period of about 40% of the length of your cycle.

So for example, this could mean taking Tongkat Ali Extracting it for 8 weeks, and then breaking it for 3.5 weeks. Or taking Tongkat Ali extract for 5 days and then taking off 2 days. I highly recommend the second cycle as it is more for people looking to boost their sex drive and will allow you to keep taking it long-term.
Sean Russell
CEO, Founder | Menprovement

Why do you have to do this?

Simply because if you don’t, your body builds up a tolerance to the herb. But by simply adding in this cycling, the body stays receptive and the effect of the Tongkat builds up over time. You are not starting back at square one after each weekly cycle. See each one as another step up.

As far as how many pills to take and when. That will be listed on your manufacturer’s recommendations. They will also have more information on how to cycle etc.

What Extract to Buy?

A shop with different herbs and eurycoma longifolia jack

Eurycoma longifolia jack comes in a lot of different forms. You can even buy it in root powder form (don’t!). So before we talk about dosage, we have to talk about the different extracts available.

The most common extracts you will see are 1:50, 1:100, and 1:200. These extract strengths mean that for 1:50 for every 1 part of the Eurycoma longifolia jack, you get 200 parts of the Eurycoma Longifolio Jack extract (Tongkat Ali extract).

  • Natural testosterone booster

  • Muscle gain & fat loss

Some people say that anything above 1:4 extract is bullshit and there is no way to tell exact extract counts. I don’t believe them, because if you do as I did, and read everything that I link to at the bottom of this page, you will see that most people who have tried the root extract and lower extracts did not have the desired effect.

And once they went on a more concentrated extract, it worked for them.

Sean’s Tip:

I recommend that you go with an extract strength of 1:200, as this is the strongest. I also recommend that you start slow (we talk more about this below) because, at high extracts, it is harder to find your exact dosage.

Everyone is different. And why works for some, maybe too much for you. You will know if you have taken too much. Insomnia, agitation, aggressiveness, and other mild symptoms will be present.

So start slow, maybe only 1 pill a day the first week and work your way up. This way you will find the perfect amount that works for you.

What Tongkat Ali Dosage to Take

So when it comes to dosage my only recommendation is this:

Look to buy 1:200 extract from a reputable brand (we will list some below) and follow your manufacturer’s dosage guidelines. Work your way up to your first dose slowly. If you feel any symptoms before the recommended dose, you have gone too far, take less. If you reach the recommended dose, just keep taking that.

What to Expect When You Start a Tongkat Ali Extract Regime

eurycoma longifolia jack

Well for starters, expect good things. But saying this, there are a lot of things that you need to know and everybody is different.

In week 1 you shouldn’t expect any crazy results. Tongkat Ali extract takes time to kick in.

By week 2 you should start to notice an increase in your sex drive and better recovery after workouts.

By week 3 you should start to feel the Tongkat Ali extract coming on strong. Sex drive, better ejaculations, some more drive and vigor, and a better sense of well-being may be present.

After a month you will have a significantly higher level of testosterone coursing through your blood. This will result in some fat loss, muscle tone, and everything else we mentioned.

Just keep cycling it and doing your thing. Just be patient.

Safety and Precautions When Buying

It’s important to know that Tongkat Ali is one of the most easily faked products on the web. You need to know what you’re doing when ordering the stuff because there is a lot of garbage out there.
Here’s what to look out for:

1) Buying on The Web – What You Need to Know!

As I mentioned above, there are a lot of different Tongkat Ali’s sold out there. The internet is full of them, and sadly it is one of the easiest herbs to fake. And people do it all the time.

  1. So for starters, don’t buy Tongkat Ali root powder. You want tongkat ali root extract. Important.
  2. Some Tongkat has been found to have high mercury levels. Don’t let this scare you, just take it seriously. A well reputable distributor, like the one we list below, will check mercury levels so relax. Just don’t cheap out and buy from anywhere sketchy.
  3. Then, follow the guidelines below to differentiate between and real and fake Tongkat Ali extract distributors.

2) Real vs fake tongkat ali extract

a hacker selling tongkat ali extract on the deepweb

There are some great tips you can use before you purchase eurycoma longifolia that will help you avoid eating the wrong stuff.

a) Find out if they are a registered business

If you find somewhere where you want to buy from, make sure they are a legit registered business and not some dude sitting in his grandma’s basement cutting Tongkat Ali root powder with God knows what.

b) Check out the contact page

Does the site have a contact page, with a phone number and email? And more importantly, do they answer when you reach out? If not, stay away. They may be okay, but if they don’t answer and your order is wrong or gets lost good luck.

c) Beware of outlandish claims

If someone claims to have the most super awesome 1:500 extract for $9.99, stay away. Tongkat Ali extract is an investment in your health. Don’t cheap out.

d) Search the company name online

Search the company name in Google, because if they do suck, then people are going to be on there letting you know or just buy it from the creator of the video (reputable) so you don’t have to worry about it.

Where to Buy Reputable Tongkat Ali Extract

eurycoma longifolia jack farmer

There is a lot of reputable seller of eurycoma longifolia jack on the web. Don’t let the section about precautions scare you, not everyone is out to get you, but let it prepare you!

Some people prefer to buy a mixture of a bunch of herbs that also contain some eurycoma longifolia.

I do not recommend this because it is easy to manipulate and put anything in there. I recommend buying straight Tongkat Ali extract. If you want to take other stuff as well, buy that separately.
Sean Russell
Founder, CEO | Menprovement

I have purchased eurycoma longifolia from a few different sources. I have come to know the most reliable distributors are the plantations of the Sumatra jungle in Indonesia. There are multiple suppliers to choose from.

The problem?

  • Buying it from the supplier is very expensive unless you buy it in bulk.

The solution?

  • You buy from someone who is buying in bulk from them.

While there are a lot, is the one that I use.

Why You Should Buy Your Tongkat Ali Extract At Herbolab

Herbolab tongkat ali extract compared to other brands

1) They buy straight from a supplier of the Sumatra jungle

They used to buy from, which is a big supplier of Eurycoma longifolia from that jungle, which you will find great reviews of around the web. But Herbolab was unpleased with their quality after testing each batch and now uses a supplier who performs chemical and microbiological analysis of every batch they produce. This brings me peace of mind.

2) They test every bottle

On top of that, the owner opens all bottles, tests each order for heavy metals and impurities, and then repackages them. This is important to me because remember what we said above – you have to make sure you are buying from a source that has checked mercury levels or they can be dangerously high. We don’t want that.

3) They ship from the U.S. via Amazon.

This is a safe and reliable outlet. They also ship from a center they have overseas if you are not in the U.S.

There are other resellers of and similar plantations around, but I have had zero issues with thus far and they are a company you can actually reach for customer service. That is hard to find in this industry. But I say as long as they are a reseller of that site, you are good to go.

Tongkat Ali Side Effects

A professor analyzing tongkat ali on a board

Alright, bros! We’re getting real about Eurycoma Longifolia, or as we know it, Tongkat Ali. It’s got serious benefits but let’s be clear, it’s no magic potion without side effects. Even superheroes have their weaknesses, right? So, let’s talk the potential kryptonite of taking Tongkat Ali extract. 💪

1) Insomnia

Eurycoma Longifolia can rev up your energy to an 11, leading to insomnia for some. Imagine chugging five espressos before hitting the sack—yikes! If you’re counting sheep into the wee hours, dial back your Tongkat Ali dose.

2) Agitation

A bit of the grump is another side effect of Eurycoma Longifolia. You’re not turning into the Hulk, you’re just a little edgier. If you find yourself snappier than a crocodile, it’s time to reassess your Tongkat Ali dosage.

3) Increased aggression

Taking Tongkat Ali extract can sometimes spike your testosterone, transforming you into a T-Rex with road rage. If you’re feeling more aggressive than a wrestling champ on steroids, it’s time to rethink your Eurycoma Longifolia intake. We want to be lions, not dinosaurs…

4) Increased anxiety

Even though Tongkat Ali boosts mood, Eurycoma Longifolia can intensify anxiety for those prone to it. If you’re feeling anxious, pump the brakes. No point in revving your sex drive if you’re too jittery to strut your stuff! 😨


Caffeine may enhance the side effects of Tongkat Ali. If you are feeling side effects, try cutting down caffeine levels along with cutting down your Tongkat Ali levels.

Remember, everyone reacts differently to dietary supplements. Start slowly with Tongkat Ali and build up. If you start to feel any of these side effects, you have reached a dose too high for you to handle. Cut back. Or stop completely.
