Consumers are using scientific evidence to make better decisions when comparing Tongkat Ali vs. Fadogia Agrestis. And you should too.
Tongkat Ali and Fadogia Agrestis are androgenic plants with benefits that includes increasing testosterone, libido, muscle strength and sports performance.
However, which is a better herb? And you should you combine Tongkat Ali and Fadogia?
This article shares the benefits of Fadogia Agrestis and Tongkat Ali, its side effects, safety limits, toxicity levels and whether Tongkat Ali Fadogia combo brings the best results.
Our guide will help you decide how to use Tongkat Ali and Fadogia effectively and which herb is better to achieve your health goals.
Let’s find out.
Originating from Nigeria, pairing Fadogia Agrestis with Tongkat Ali may seem like a perfect health stack.
Celebrity doctor Dr. Andrew Huberman once told his audience in 2022 how Fadogia and Tongkat Ali may be used to boost testosterone. His statement caught many nutritionists, botanists and scientists by surprise.
Further investigations revealed that Fadogia Agrestis may be another overly-hyped herbal supplement without strong clinical evidence. For example, Turkesterone failed to attract interest from users due to the lack of scientific evidence and severe side effects.
"Never fall for the Nigerian Fadogia scam.”
Eventually, some will hate us for exposing the truth.
With less than 10 research studies since 1970, there is a lack of scientific evidence and clinical tests on humans to prove Fadogia’s health benefits. In comparison, Tongkat Ali recorded more than 300+ studies and human clinical tests in the last 20 years.
Yes, you may combine Tongkat Ali and Fadogia Agrestis to gain added benefits such as energy, strength and testosterone boost too. Although much of these compounded effects are fueled by the powerful bioactive ingredients of Tongkat Ali.
Now, let’s find out which herb is better to achieve various health goals.

Testosterone Production
Multiple RCT studies and meta-analyses showed Tongkat Ali produces more total testosterone by reducing SHBG compared to Fadogia. Fadogia’s effect on testosterone is limited to animal studies. However, combining both Tongkat Ali and Fadogia may result in a substantial increase in total testosterone based on anecdotal evidence shown from the user’s bloodwork after a few weeks.
Weight Loss
Tongkat Ali works better as a weight loss supplement compared to Fadogia Agrestis as it promotes faster body metabolism and reduction of body fat. Tongkat Ali’s studies showed a reduction in body fat loss and Body Mass Index (BMI) in obese adults after 100 days. On the other hand, there are no studies on the effects of fat loss or BMI in humans from taking Fadogia Agrestis.
Mood & Stress
Tongkat Ali performs better in reducing stress and improving mood caused by hormonal imbalance compared to Fadogia Agrestis. Various studies that showed Tongkat Ali is able to reduce cortisol (i.e stress hormones), boost dopamine (happy hormone) and improve overall mood profile (Tension, Anger, Confusion and Stress reduction). Tongkat Ali is also widely used to reduce brain fog to gain better mental clarity in the morning compared to Fadogia.
Immune System
Tongkat Ali may be a better choice to boost your immune system compared to Fadogia Agrestis due to anti-oxidant and anti-bacterial properties. Randomized controlled Tongkat Ali clinical trial on humans showed improvement of the immune system after 12 weeks, with an increase of CD4+, T-cells. No study was done on Fadogia Agrestis to investigate the effects on the immune system at this juncture. Fadogia recorded no anecdotal evidence in boosting immune system.
Sports Performance
Both Tongkat Ali and Fadogia Agrestis recorded substantial improvements in stamina, muscle strength and energy. However, Tongkat Ali is more widely used and trusted as a sports supplement for pre-workouts and post-workout muscle recovery compared to Fadogia. Combining Tongkat Ali and Fadogia may improve muscle strength and growth based on anecdotal evidence by users in the fitness community.
Libido
Tongkat Ali performs better than Fadgoia in boosting libido and men’s fertility. Studies on Tongkat Ali showed longer erection time and higher sperm count and motility in men with androgen deficiencies (i.e low-T). Tongkat Ali delivers the same libido boost in young adult men compared to Fadogia Agrestis. Combining Tongkat Ali and Fadogia may increase libido due to the aftereffects of testosterone production.
Tongkat Ali is time-tested to be more popular than Fadogia Agrestis. Google data showed that consumer search interest in Tongkat Ali jumped exponentially by more than 50%, surpassing Fadogia Agrestis in Q2 to Q3 in 2022.
Our analysis revealed that the lack of user interest in Fadogia Agrestis is due to safety concerns and insufficient evidence to back its health claims.

Meanwhile, Tongkat Ali is more popular than Fadogia Agrestis due to its decades of clinical tests on humans, with rapid studies being conducted globally by independent research labs by medical professionals.
In comparison, Fadogia recorded less than 10 studies and limited to tests conducted on albino rats.
"Products should not be promoted as if they have benefits for our health when it’s never been proven that they work in humans.”
Despite the lack of scientific evidence, Fadogia and Tongkat Ali are both used by fitness community, bodybuilders and sports amateurs.
Manufacturers and brand owners are selling Tongkat Ali Fadogia supplements with aggressive claims such as “boosting more health benefits”.
That brings us to the next topic.
The best Fadogia Agrestis Tongkat Ali brands out there each has their own unique formulation to bring the best out of Fadogia.
The trick is by adding a small quantity of potent Tongkat Ali with Fadogia in a single capsule to boost its overall health benefits (eg: testosterone, libido and mood).
Following the optimal dosage recommended by Dr. Andrew Huberman, the best Tongkat Ali Fadogia Agrestis supplement contains a mix of ingredients in the following ratio:
Many reported faster gains in muscle growth and stamina after combining Fadogia Agrestis and Tongkat Ali. You may experience higher testosterone levels after four weeks.
However, most of these health benefits or gains are placebo, not verified and not clinically tested by scientists.
The real benefits of Fadogia-Tongkat Ali supplements that you buy may be fueled by Tongkat Ali’s stronger bioactive ingredients such as eurycomanone, glycosaponin and others.
In fact, you probably gain more health benefits from consuming a potent single-ingredient Tongkat Ali product that is clinically tested.
Let’s deep-dive into the claimed health benefits of Tongkat Ali Fadogia supplements.
Here is an example.
600mg of Fadogia Agrestis + 400mg of Tongkat Ali (i.e 1,000mg of Fadogia Agrestis Tongkat Ali mix) may bring similar effects on testosterone or libido compared to 200mg of Tongkat Ali.
When formulating or marketing a herbal formulation, the total net gain from combining two (or more) herbs is NOT equal to the sum of the individual gains.
Yet, most people think 1 + 1 = 2
Or, in this example; Testosterone Gain From Fadogia + Testosterone Gain From Tongkat Ali = 2
This allows further manipulation into thinking that the sum of 0.6 + 1.4 = 2
This is how we are wired to think when rationalizing the compounded effect of Fadogia Agrestis (at say 1,400mg) and Tongkat Ali (at say 600mg).
Unless it is clinically tested, combining Fadogia Agrestis and Tongkat Ali will NOT give you 2x higher testosterone gains, or 2x more libido, or the elusive 10x more muscle strength.
In fact, you can gain 2x higher testosterone gains or 2x more libido with a clinically tested potent Tongkat Ali at a lower dosage.
Now, let’s find out more facts about Tongkat Ali and Fadogia Agrestis.
Current research on Fadogia Agrestis doesn’t show enough evidence that this plant can help with any medical condition
Tongkat Ali’s benefits are amplified when combined with other herbs like Fadogia Agrestis, Maca, Horny Goat Weed and multivitamins
Whilst it is advisable to consume Fadogia Agrestis and Tongkat Ali simultaneously in high doses, you may still reap some noticeable benefits. The result of combining both Tongkat Ali and Fadogia include:
The potential benefits of Tongkat Ali and Fadogia Agresti make it popular if you are using it as a pre-workout or post-workout supplement, or by those who are actively involved in sports.
However, there is a catch.
Most of the benefits from Tongkat Ali – Fadogia combo are anecdotal and not supported by research or empirical data.
The real-world benefits from Tongkat Ali Fadogia Agrestis combo may be caused by placebo, but it could also possibly be due to faster absorption and gains that happen from a higher dosages of Tongkat Ali in the combo mix.
Some people claim that Fadogia agrestis can increase testosterone levels, which could help with sexual performance and athletic performance. But this claim isn't supported by research.
There are serious toxicity risks and side-effects on Fadogia Agrestis as reported by medical and dietary experts.
Fadogia side effects and toxicity studies are limited to animal tests (mainly rats and rabbits). Results from various studies conducted in 2008, 2009 and 2012 showed the following side-effects of Fadogia:
Common Fadogia’s side effects from consumers:
Based on nutritional and health experts’ views, Fadogia Agrestis is NOT safe when consumed in high doses.
There are limited clinical studies on humans and past studies showed an adverse effect on kidney and liver functions.
Nutrition and food science expert Zach Allison advised viewers on the risks of taking Fadogia Agrestis in his recent video.
In his review of Fadogia, Zach exposed the truth behind Fadogia Agrestis and highlighted the risks of Fadogia using data-driven facts from studies and other references.
Until we have more data (to prove otherwise), the risks on Fadogia Agrestis should be taken seriously.
He also commented on the risk vs. reward for those taking Fadogia Agrestis.
If you are taking unproven and experimental supplement to increase testosterone, you have to take into account the risk-to-reward ratio.
Despite his unpopular opinion about Fadogia, it makes a lot sense to stay away from Fadogia Agrestis until there are more research studies or clinical trials / tests on humans.
There are no research studies or clinical tests to prove the effect of Fadogia Agrestis on women’s health. There is more compelling scientific evidence on Tongkat Ali compared to Fadogia Agrestis.
Find out how Tongkat Ali may benefit women’s health.
When consuming any Fadogia Agresits-Tongkat Ali supplements, it is Tongkat Ali who does all the hard work whilst Fadogia gets the credit.
Thanks to all the false marketing hype, Fadogia Agrestis failed miserably to meet consumers’ expectations despite it claims to increase testosterone by 350%.
Joe Rogan and Dr. Andrew Huberman raved about Fadogia in past talk shows, but both did not elaborate on the scientific studies to back the potential health claims.
In fact, Fadogia Agrestis’s health benefits are seen as a pseudo-science that is not backed by any randomized clinical trials or studies on humans.
Fadogia Agrestis has no scientific evidence to support any use.
Medical professionals, nutritionists and scientists did not further comment on Fadogia’s health benefits due to lack of scientific studies in the last 20 years.
Here is the painful truth behind Fadogia Agrestis.
The perceived health benefits (or boosted effects) may potentially be due to the fact that Fadogia Agrestis act as an enabler or “booster” when combined with Tongkat Ali’s bioactive ingredients.
The added boost may come from high-protein bioactive ingredients (eg: saponin) which are available in both Fadogia and Tongkat Ali.
But as we explained earlier, the total gain from a multi-herbal supplement is NOT the sum of its individual parts (i.e 1 + 1 is not equal to 2).
As a single-ingredient supplement, a potent Tongkat Ali extract may be stronger than Fadogia-Tongkat Ali combo. It requires a modest 200mg of pure extract to deliver all its scientifically proven benefits.
On the other hand, you may need a higher amount of 600mg to 1,000mg of Fadogia Agrestis to supercharge all Tongkat Ali’s amazing benefits.
Hence why most Tongkat Ali Fadogia Agrestis supplements are formulated in high dosages – without even considering the medium and long-term negative side effects of consuming Fadogia in high doses.
Let’s take look at a popular Tongkat Ali Fadogia Agrestis supplement on Amazon. Each capsule contains 1,000 mg of Fadogia Agrestis and Tongkat Ali.
Here is the breakdown for each serving (capsule) from its Supplement Facts:
Tongkat Ali has 20 years of scientifically proven benefits than Fadogia Agrestis in areas such as testosterone, muscle strength and libido.
Given Fadogia does not have sufficient studies to claim its effect on testosterone, energy, libido and many others, is Tongkat Ali doing a perfect job to mask Fadogia’s deficiencies and weaknesses?
Perhaps it is time to take note of the potential red flags of Fadogia from Andrew Huberman’s raving podcast
The reality is, Tongkat Ali is a versatile herb that react positively with Fadogia, Turkesterone, and Ashwagandha. However, adding two different herbal extracts in a single capsule may not be a good idea.
We have learned that Fadogia Agrestis is an enabling ingredient to boost the overall effects of Tongkat Ali.
Hence that is the reason why the Tongkat Ali Fadogia supplement is so popular.
However, if you have tried a single-ingredient potent Tongkat Ali before, then adding Fadogia to your daily stack may result in marginal increase to testosterone and other health benefits.
In fact, consuming a highly potent Tongkat Ali using standardized hot water extract may add more health benefits and gains in lesser time compared to Fadogia Agrestis.
However, if you opt for generic Tongkat Ali, or Fadogia Agrestis-Tongkat Ali supplement, there are three ways in which you can supercharge Tongkat Ali’s effects.
First option: increase the Tongkat Ali dosage to 600mg to 800mg daily, which makes a significant boost to testosterone, and libido. Or you may perform kegel exercises or weight training 3-4 times a week.
Second Option: Add Fadogia Agrestis, Maca, and caffeine to Tongkat Ali to boost the effects.
Third Option: Take Tongkat Ali with multivitamins.
A clinical trial on men and women showed a phenomenal boost of free testosterone when consuming a 50mg of Tongkat Ali together with multivitamins. The test result showed an increase of 500% to 600% in free testosterone for both men and women after 24 weeks.
Before we dive in, let’s rephrase that question for clarity.
So should you consume a herbal-mix combo supplement such as Tongkat Ali Fadogia Agrestis, or stick with a single-ingredient Tongkat Ali supplement?
Here is one perspective. And food for thought.
We have demonstrated that there are ZERO ADDITIONAL health benefits of adding Fadogia Agrestis with Tongkat Ali.
And we have shown that Fadogia Agrestis has less 10 research studies to back up its claims on testosterone, libido, muscle strength, and other health benefits.
As the herbal supplement industry is not regulated by FDA, brand owners are hyping up the placebo effects through paid personalities and influencers.
Joe Rogan & Dr. Andrew Huberman failed to convince consumers of the scientific evidence behind the benefits of Fadogia Agrestis.
The scariest part is that most health claims or benefits from Fadogia Agrestis are anecdotal and not backed by any clinical tests, or peer-reviewed research studies.
And that’s the reason why both Tongkat Ali and Panax Ginseng remain single-ingredient herbal supplement for centuries.
And there are no compelling reasons to create a cocktail mix of herbal supplements into a single capsule.
All Fadogia Agrestis products on Amazon have NOT been clinically tested on humans
Yellow Tongkat Ali (Eurycoma Longifolia) is a more powerful androgenic plant than Fadogia Agrestis and its bioactive ingredients are scientifically proven to benefit male and female hormones.

According to health expert Dr. Kyle Gillet, “Tongkat helps with the conversion of multiple key steps where you synthesize testosterone,” whilst for Fadogia, “it will increase the release of luteinizing hormone from the pituitary gland”. Whilst these statements are taken from two separate studies, there are no combined studies to investigate the testosterone effects from combining Fadogia and Agrestis together.

Studies on Fadogia and Tongkat Ali have both shown increase in sperm count. Whilst Tongkat Ali is reported to higher effect on sperm count based on human clinical studies, Fadogia’s effect of increasing sperm count comes with inherent negative side effects such as irreparable kidney damage and liver tissue degeneration (necrosis) at 50 mg/kg of body weight.

An animal study by Yakubu et al from the University of Ilorin Nigeria in 2007 showed that Fadogia Agrestis (18 mg/kg) caused “mild but reversible destruction” of spermatic cells and irreversible derangement on male testicular histology.
Based on an animal study, Dr. Gillett said a safe dose of Fadogia is 300 mg per day, although aspiring bodybuilders and sports amateurs are taking a higher dosage of 600 mg three times a week depending on the body weight. Aspiring bodybuilders weighing 200 lbs are reported taking massive 700 mg to 1,450 mg of Fadogia which may have severe effects on health.
An animal study in 2023 concluded that Fadogia has adverse effects, causing irreparable damage to both the liver and kidneys. Rats exposed to 50 mg/kg of Fadogia extract showed ballooning necrosis (tissue degeneration and death) and massive inflammation in both the liver and kidneys.
A recent study on albino rats showed that Fadogia is highly damaging to kidneys and liver at low dosages of 50 mg. In addition, the safety limit and toxicity of long-term use of Fadogia have not been established in any conditions, which suggests that Fadogia is potentially highly toxic to humans.
The most severe side effects of Fadogia may cause irreparable kidney and liver damage if taken at higher dosage. Other common side effects include potential damage to vocal chord, increased blood pressure, increased heart rate, nausea, headaches and vomiting.
If your health goals demand the use of both Tongkat Ali and Fadogia, the best way is to take both herbs in moderation at lower dosages for a short duration. A daily dosage 200 mg Tongkat Ali and 300 mg Fadogia is ideal for first-timers and those who experience fewer (or no side effects) may increase the dosage after 2 weeks or longer.
It is recommended to use Fadogia Agrestis and Tongkat Ali as single-ingredient (separate) supplements based on your health goals. This allows your body to adapt to various bioactive ingredients and to monitor any reactions or side effects.
Whilst the Tongkat Ali-Fadogia supplement can be used to enhance your sports performance and boost your testosterone faster, it is best to stick to single-ingredient supplements such as Tongkat Ali that are clinically tested to benefit your health.
As long-term side effects and health benefits remain bleak, Fadogia Agrestis warrants further clinical tests to ensure its safety and efficacy.

Valid points indeed. However, how did Dr. Andrew Huberman have the confidence to put it on the spotlight more than once? He’s very careful with what he says and it does strike me as odd that he would give something with “poor research” this status. Seems like something’s off.
I believe he mentioned once that he prescribed Fadogia to military or profesionnal sports athletes, as a way to circumvene regulations about steroids. If you analyse this statement carefully, you will notice that professionnal sports have become a sort of race between the anti-doping doctors and the other doctors working with the athletes to help them win. The doctors working for the athletes have their own playbooks that are constantly in evolution to keep the athletes at least one notch ahead of the other athletes and ahead of the anti-doping tests. What we could understand is that fadogia is a page of the coaches’ playbook that has been around for long enough that it’s no longer top secret, and since it may help a lot of regular people and is easy to buy, Huberman just decided to disclose that secret. He was careful to recommend a lower dose than what other people recommend, as a protection against the risk of toxicity that is known about fadogia (but honestly, I believe that actual synthetic steroids come with a much longer list of side effects and health risks).
Looking what Dr. Andrew Huberman said his interview with Joe Rogan, I reckon he is not equipped, nor has the knowledge to talk about Fadogia Agrestis. After reading this article, I don’t think he even know that Fadogia has very few studies to verify its health benefits.
Something is off here. I doubt he is able to convince the public on the merits of Fadogia. Or is he just another snake oil seller? God knows. There are many “Doctors” with hidden agenda these days.
TBH, I tried Fadogia (by DoubleWood supplement) in high doses for 4 weeks with no effect on testosterone or libido! I took a blood test to prove there wasn’t any increase in my free and total testosterone. The Amazon world is filled with fake claims by brand owners on Fadogia. Beware of Fadogia and stay from herbs that makes too much noise and hype on social media. Thats my two cents worth.
The two cents are about what your shilling is worthy. Beside Rogan is a circus show for snake oils sales and Huberman has his routines in such venues, I think the author and the fake comments following are even worst, demostrating that people with agendas are unable to present any kind of information without giving away what they are really about.
I disagree with you Joel. I am nutritionist for 15 years and one of my areas of expertise is herbs and traditional medicine. I can honestly tell you that those playbook for sports professionals are filled with BS. Why should you roll out untested herbs like Fadogia Agrestis to military, that has only 8 research studies? And to add, Fadogia Agrestis studies ARE DONE on RATS! Animal tests are just a preliminary tests. Fadogia Agrestis ARE NOT CLINICALLY TESTED ON HUMANS! This is bad for the liver, kidney and not may cause cancer. Huberman should not be discussing, advising or promoting Fadogia Agrestis to anyone if the herb is not thoroughly tested. He did not present the usage of Fadogia clearly to the public. I hate to say this, but until Fadogia has at least 100 research studies on humans, its efficacy and safety are not conclusive. And it SHOULD NOT BE PROMOTED OR SOLD AS herbal supplement. We are risking our lives here!
A world wide mass forced use of genetic therapies without 100 published studies apart for those telling that they kill people and sterilize the rest, would give you a better understanding of how ridiculous your comment is. Science is a craft, often a craft of evil. Scientist are low hanging prostitutes that will statistically demonstrate just about anything for money. Those using $cience to avvalorate their interests are terrible people but those regurgitating that “science” deserve only to be ridiculized and be barred to speak.
My experience is better with Tongkat Ali than Fadogia. For testosterone and energy booster, I will continue to use Tongkat Ali. It’s better to use tried and tested herb IMHO. Not sure what’s the fuss is all about with this combo-mix. I found single ingredient supplements work more effectively.
Thanks for sharing your experience on Tongkat Ali vs. Fadogia Agrestis. We receive similar experiences from others. Fadogia is a popular herbal supplement for men and to enhance sports performance. However, most consumers in the US are not getting the whole truth about Fadogia Agrestis vs. Tongkat Ali. In fact, Tongkat Ali is the best testosterone supplement compared to Fadogia Agrestis. Our research showed that most of the best-selling T-boosters sold in the market today contains Tongkat Ali. Here is the link for more information about key ingredients that are used in testosterone supplements for men.

I tried both, but Tongkat Ali performs way better than Fadogia Agrestis! For those who think Tongkat Ali is mild, and you could be wrong. The strongest and most potent Tongkat Ali are clinically tested. I can vouch from my 10 years of experience is that the best Tongkat Ali on Amazon is AKARALI brand – 100% clinically tested on humans and MORE POTENT than Fadogia. Here is the link

Joe Rogan Fadogia Agrestis formulation is a scam and overly promoted. I don’t think the formulation is not tested on humans. The reason why Fadogia Agrestis is popular is because it is marketed by Dr. Andrew Huberman. I won’t buy any Fadogia (or any herbal supplements) that is marketed by “Doctors” in the USA. And I agree with you that Tongkat Ali doesn’t need doctor’s spokesperson to convince people to buy. With more than 300 studies, that what makes Tongkat Ali more authentic and real than Fadogia Agrestis.
Iam 35 and Fadogia didn’t work on me. Here is my review of Fadogia. Did my blood test and found no increase in testosterone after consuming Fadogia for 5 weeks. My verdict of Tongkat Ali vs. Fadogia is simple. If you want a significant boost of health with increase in testosterone, then choose Tongkat Ali. Tongkat Ali seemed to work better than Fadogia Agrestis for people in the age group between 35 and 70 to boost testosterone. You guys should check out some great article here on how Tongkat Ali helps you to revitalize your health and work productivity.

Fadogia Agrestis is not safe and it has inherent risks. Why are you guys still buying a risky herbal product that is not tested on humans? To top it up, Fadogia Agrestis has no significant health benefits. There are many who reported adverse side-effects from consuming Fadogia too. The problem with buying Fadogia Agrestis or Tongkat Ali in the US is that they dilute with impurities. And consumers end up enjoying placebo effects from Fadogia. Next time you buy, look out for the best Tongkat Ali from Malaysia!
