Kaged Ferodrox with LJ100 Tongktat Ali

Benefits of LJ100®, Patented Tongkat Ali (Longjack) Extract

Tongkat Ali is one of the oldest and most popular testosterone support ingredients in existence. It comes from the Eurycoma longifolia plant native to Malaysia, Indonesia, and Thailand and has been used as a traditional remedy for centuries.

This plant has a multitude of nicknames including Tongkat Ali, Longjack, Malaysian Ginseng, and Walking Stick.

The list of purported traditional benefits is even longer than the list of nicknames, although its well-researched effects for supporting healthy testosterone levels are arguably the most popular. Over the last few years, this has exploded in popularity as podcasters and health and fitness creators on social media have begun to talk about it more and more.

Before you go out and grab the cheapest bottle of Tongkat Ali you can find, make sure you understand that the quality of Tongkat Ali supplements can vary. 

Not All Tongkat Ali is Created Equal: Why Choose LJ100® Tongkat Ali

When you’re looking at supplements that contain Tongkat Ali, you have to look at the form. When it comes to quality, LJ100® stands out.

This form was developed in a collaboration between researchers at the Massachusetts Institute of Technology and the Malaysian government, one of the places where the plant grows natively. The result was a standardized, high-quality form that you can count on to give the benefits of Tongkat Ali that you’re looking for.

In this article, we talk about what makes LJ100® Tongkat Ali different. The undeniable advantages of this form are why we only use LJ100® Tongkat Ali in our testosterone and hormone support supplement, Ferodrox.

Key Takeaways (TL:DR)

  • Tongkat Ali has been used in South East Asia as a traditional ingredient for centuries.
  • The Malaysian Government and MIT collaborated to develop a patented form of Long Jack in LJ100®, which contains a standard amount of Tongkat Ali’s Bioactive compounds.
  • Studies on LJ100® indicate that it’s a promising anabolic agent that can positively influence cortisol:testosterone ratio levels.

Benefits of Choosing LJ100® Tongkat Ali

Here are the benefits of choosing this form over generic or other forms of Tongkat Ali.

1) Consistent, Standardized Dose of Bioactives

When looking at an array of herbal and extract ingredients, it’s not just the dose that matters, it’s also what percentage of this dose contains the potent compounds.

We see this across an array of ingredients in all kinds of supplements. When you take a supplement, you’re obviously not getting the whole plant, you’re getting an extract that’s designed to give you the good stuff of the planet, without the unnecessary parts. 

With Tongkat Ali, this means you should look closely at the percentage of the bioactive compounds. They’re called Europeptides and Glyco Saponins.

LJ100® contains a standardized amount of 22% Eurypeptides and 40% Glyco Saponins.

This way, every single capsule, bottle, and batch you’re getting a standard, effective dose. 

How do you know if that’s the case for your Tongkat Ali supplement? It’s as simple as looking at the label. If it doesn’t say somewhere that it’s standardized to contain the Bioactive compounds, it’s probably not. This means you have no idea how much of these important compounds you’re getting, which meaning inconsistency batch to batch, and uncertain effects on your body.

Here’s a screenshot of the Ferodrox label, so you can see exactly what to look for.

When you choose LJ100® Tongkat Ali, you know you’re getting a standardized amount of these Bioactive compounds.

2) Backed by Real Scientific Studies

We say Kaged supplements are “science-backed” because we choose the specific forms of ingredients that have been used in studies and the doses used in studies. That’s the case with LJ100®. 

Often, people will mention the benefits of an ingredient, but not look at which form was used in the studies and provided those benefits. If you want the same results as shown in research, logic follows, you should use the same form.

In this case, LJ100® is the specific form of Tongkat Ali backed by many scientific studies. Here’s an overview of just a few, with links to the studies in case you want to dive deeper.

Pilot Study on Active Men and Women: Testosterone Support

A pilot study investigated the ergogenic potential of Tongkat Ali among an active, elderly population.  The study had 25 physically active men and women supplement with LJ100® Tongkat Ali for five weeks. At the end of the study, the researchers noted significant increases in total and free testosterone as well as muscle force in both genders. [1]

LJ100® and Stress Support Studies

One study examined the effects of Tongkat Ali supplementation on stress hormones and psychological mood state. The researchers split 63 subjects (32 men and 31 women) into two groups.

Over the course of four weeks, one group supplemented with 200 mg/ day of Tonkgat Ali, while the other group used a placebo. 

At the end of the study, the researchers saw reduced cortisol levels, increased testosterone status, and an overall improvement in the cortisol:testosterone ratio in the Tongkat Ali group.[2]

In another study, researchers examined the effects of Tongkat Ali on testosterone and cortisol levels during intense endurance events.  Thirty male subjects participating in a 24-hour mountain biking event were assessed, whereby half of them received a placebo and half supplemented with Tongkat Ali 30 minutes prior to the event.  The researchers saw lower cortisol levels and higher testosterone levels in the group that supplemented with Tongkat Ali. [3]

Strength and Performance Increases with LJ100® Tongkat Ali Supplementation

A pilot study was conducted on 14 healthy men undergoing a strength training routine where half of them supplemented with LJ100® Tongkat Ali and half received a placebo. 

The subjects followed a circuit training routine for a total of five weeks. At week one, they performed 2 sets of 10 at 60% of their 1RM at ten different exercise stations, then increased the intensity by 10% each week.  While both groups made significant strength gains, the Tongkat Ali group demonstrated a greater percentage increase in strength compared to the placebo group (6.78% and 2.77% respectively). [4]

A 12-week study was done on 31 women to examine the effects that Tongkat Ali had on physical function and muscle size.  One group supplemented with a placebo and the other group supplemented with Tongkat Ali.  Both groups did two strength training sessions a week consisting of work done at 60% of their 1RM.  Both groups saw significant improvements in their leg press and bench press numbers, but the group that supplemented with Tongkat Ali showed increased muscle endurance and muscle size. [5]

How Does LJ100® Tongkat Ali Work?

While there are a few hormonal responses with supplementation of Tongkat, the precise details as to how and why it works are still relatively unclear.  LJ100® may increase the bioavailability of testosterone by lowering the amount of sex hormone binding globulin (SHBG) in the blood. LJ100® may also be involved in reducing the conversion of testosterone to estrogen, balancing the supply of this anabolic hormone. 

Tongkat also contains eurypeptides that have been proposed to activate an enzyme which increases the biosynthesis of testosterone. This has led some scientists to suggest that Tongkat acts more as a testosterone “maintainer” rather than a booster as it helps maintain levels within the normal range.  

Who should be interested in LJ100?

From the studies on LJ100, its most promising effects revolve around its ability to promote a favorable hormone profile. Males who are 30 years old and older would likely see the most benefits, but Tongkat studies have shown benefits among both men and women. With this in mind LJ100® may be a good supplement for anybody looking to support healthy, natural hormone production.

What’s The Optimal Dosage of LJ100® Tongkat Ali?

In Ferodrox, we used 200mg of LJ100® per serving. We chose this dosage because 200mg daily was commonly used in many of the studies which found Tongkat Ali to be significantly effective.

Again, going back to what we mean by “science-backed,” the right form is the first part, and the right dose is the second. 

Where Can You Find LJ100?

Ferodrox is one of your best sources to get LJ100®. Ferodrox contains 200 mg of LJ100® per serving.

This dosage was commonly used in many of the studies which found Tongkat to be significantly effective. 

Ferodrox also contains other scientifically tested ingredients including KSM-66® Ashwagandha and PrimaVIe® ShilaJit, which have also been found to have positive scientific research findings.

Altogether, Ferodrox provides complete hormone support. It will help keep testosterone, cortisol, and estrogen levels in the healthy range.*

What The Kaged Community Says About Ferodrox

Ferodrox is one of our most popular and highly-reviewed products, and we’re very proud to showcase the positive impact it has had on the Kaged community. 

“Added this to my routine 6 weeks ago and love the results. My training capacity has increased and my body is responding to the stress management with better sleep cycles.” - Dumont W.

Focus, Drive And Sustained Energy. I'm not sure what's happening. Been using this for about a week. My sleep habits have stayed the same 6-7 hrs average. However, I have noticed sustained energy throughout my day. It has helped get more done at work and the drive to get those late night workouts in. I am stacking this with Kaged Creatine HCl supplement as well.” - Erik W.

More Energy. It can sometimes be hard to quantify the effects of a supplement like this, without doing a T test. However, what I can say is, on the rare day I forget to take this, I notice my energy/drive/motivation is less when I go to workout. The other side of that coin is normally when I do take it, it makes it just that much easier to really push myself, or to bang out my last set to failure.” - Mark S.


If you want to maintain healthy T levels, try Ferodrox with LJ100® Tongkat Ali for yourself.
