“I took 400mg Tongkat Ali daily, preferably in the early morning to get stimulant effects” said Dr. Andrew Huberman during the Joe Rogan podcast. Since then Huberman Lab Tongkat Ali supplement from Momentous caught the attention of many American consumers.
But is Momentous Huberman Lab Tongkat Ali a high-quality supplement that works in the real world? Or is it a scam?
In this in-depth technical review, we’ll explore whether Momentous (Huberman Lab) Tongkat Ali is worth the hype, is it a scam and does it have any effects on testosterone, libido and muscle growth based on customer feedback and from our research analysis.
Momentous is a US-based supplement and sports nutrition company headquartered in Utah, with a focus on consumers with the highest quality and most innovative products. Through its Huberman Lab podcats led by Dr. Andrew Huberman himself, consumers may find various topics being discussed, from nutrition to well-being without touching much on Momentous supplements. It is believed that Dr. Andrew Huberman propagates pseudoscience with strong scientific evidence to back up his claims, and his Momentous supplements are “scientifically backed and the highest quality ingredients”, and have been rigorously tested by independent 3rd parties.
Our analysis showed that Huberman Momentous Tongkat Ali (60 capsules) is priced at USD 19.90, with functional health claims that it may boost testosterone, benefit libido, body composition, build stronger muscle and accelerate recovery.
However, we found that the extract was not standardized to meet the optimal bioavailability standards set by the Malaysian Tongkat Ali Standard MS2409 – a known industry standard used in premium extracts by manufacturers and suppliers. In addition, the extract was not used in clinical trials nor performance tested by athletes to warrant a wide range of health claims. It seemed like Huberman Lab Tongkat Ali is a magical pill that is too good to be true.
But again, using a non-standardized extract with lower potency does not mean Huberman Lab Tongkat Ali is a scam. It could still be legit, but the brand is shrouded by shady claims from rising credibility issues.
Being a legitimate US-based company, Momentous itself has been awarded 6 innovation contracts from the US Department of Defense to create human optimization products, with most it’s herbal ingredients such as Tongkat Ali was imported from Indonesia and manufactured in the United States.
But does it work?
We shall investigate later in this article.
According to a PR statement issued by Momentous, Dr Huberman joined Momentous’ Scientific Advisory Board in 2022. Momentous and Dr. Huberman’s Health & Fitness podcast, known as the Huberman Lab Podcast, entered into a multi-year partnership to promote the benefits of Tongkat Ali, Fadogia Agrestis and other herbs in the US.
The commercial partnership with Dr. Huberman will leverage his scientific knowledge across multiple disciplines of brain and body health to support Momentous’ growing stature in the supplement industry.
The fact that Dr. Andrew Huberman was never involved or published any research study on Tongkat Ali made him less credible on the subject.
Dr. Andrew Huberman’s commercial involvement with Momentous has attracted various controversies, debates and distrust amongst health professionals and herbalists.
Are celebrity medical and health experts like Dr Andrew Huberman a boon or a bane? His role as a science-based communicator (rather than a subject matter expert on Tongkat Ali and Fadogia Agrestis warrants a thorough review given his lack of in-depth knowledge or involvement in Tongkat Ali reearch.
Unlike the MIT-Tongkat Ali developed by a group of MIT and Malaysian scientists in the past, Huberman Momentous supplements are viewed by medical professionals as a marketing hype, by capitalizing his Stanford credentials in neuroscience to propagate Tongkat Ali on Joe Rogan podcasts.

Huberman Tongkat Ali by Momentous is formulated using 200mg of Indonesian Tongkat Ali per capsule. According to the supplement facts published on the label by Momentous, there are other ingredients such as rice flour (a form of filler), hypromellose and magnesium stearate that make it less pure, or less potent.
The addition of excessive rice fillers or maltodextrin are known to dilute the purity of Tongkat Ali, and assuming there is 100mg of maltodextrin in the 200mg Huberman Tongkat Ali, then you are effectively consuming (200mg – 100mg) = 100mg of Tongkat Ali extract.
Huberman Tongkat Ali is sourced from Indonesia, a country which lacks standardization, quality control, research and development.
Our 3rd party purity test revealed that Huberman Lab Tongkat Ali contains low bioavailable compounds, i.e eurycomanone (<1.5%), eurypeptides (<20%) and glycosaponin (<30%) due to the non-standardized extract. Whilst it is 3rd party lab tested, this low bioavailability means it may not be potent, thus requiring consumers to higher dosages (above 400mg) which may not be safe in the long run due to lower safety limits of non-standardized ethanol-based extracts.
In addition, Huberman Lab Tongkat Ali may not work to boost testosterone effectively as claimed due to low levels of saponin and eurycomanone found in the 200mg capsules. These two major bioactive ingredients must exist in a higher percentage in order to induce meaningful testosterone production in the adrenal glands.
Momentous may be a best-selling Tongkat Ali supplement in the US although premium brands such as AKARALI is deemed as a better choice amongst US consumers due to clinically tested US-patented Physta® standardized hot water root extract that delivers higher eurycomanone, eurypeptides, glycosaponin and pollysacharides bioactive compounds.
Momentous Tongkat Ali claims to source Indonesian Tongkat Ali extract from reputable suppliers. Further investigation revealed that the extracts used by Momentous are not clinically tested or used in any studies to show improvements in testosterone or libido as claimed by Dr. Huberman in his various podcasts.
This begs the question of the quality of extracts and the formulation used in Huberman’s supplements.
The addition of adulterants such as magnesium stearate in Momentous Tongkat Ali further distorts the purity and poses health risks such as the weakening of the immune system.
Our analysis showed that Momentous Tongkat Ali contains magnesium stearate, a chemical compound known to irritate the mucus lining of the bowels, triggering diarrhea and cause potential of weakening of the immune system according to health experts from WebMD.
Nonetheless, Momentous Tongkat Ali remains an affordable choice for US consumers at $19.95 for a bottle of 60 capsules. For first-time users and those seeking value for money Tongkat Ali without worrying too much on potency, Huberman Lab Tongkat Ali (200mg) offers the best Indonesian Tongkat Ali that you can buy in the US right now, outpacing established brands such as Solaray Tongkat Ali (400mg).
Despite sourcing its extract from Indonesian Tongkat Ali suppliers, the lower potency, impurities and lack of clinical trials did not deter consumers from buying Huberman Tongkat Ali. On the other end of the spectrum, more discerning US and UK consumers are choosing premium Tongkat Ali supplement brands such as AKARALI (standardized hot water extract) compared to Andrew Huberman Lab Tongkat Ali (non-standardized extract).
Many have doubted Dr. Andrew Huberman’s credentials after buying Huberman / Momentous Tongkat Ali – more so after watching hours of Huberman Lab’s podcasts, but his 1 million followers strongly insisted that he is legit despite his lack of deep-dive experience on Tongkat Ali, and myriads of personal controversies surrounding his relationship with women and his pseudoscience claims.
“He is extremely legit” said a user on Reddit, adding “however what happens in research is very different than what happens in actual doctors offices and practices”.
Our analysis showed that the collective public view of Dr. Andrew Huberman’s involvement in the Rogan-Fridman-Ferriss circle seems shady.
The fact that Dr. Andrew Huberman is not a certified medical doctor and did not publish, or wrote a single paper on Tongkat Ali means his credibility is at stake – especially knowing that he owns a stake on Momentous Huberman Supplements. Despite being a legit neuroscientist from the University of Stanford, Huberman Lab podcasts are now seen as a marketing avenue to indirectly promote Momentous Huberman Supplements.
According to a review published in Slate, “Dr. Andrew Huberman doesn’t use the responsibility as someone trained in science to be accurate and reliable.” Many Americans have now raised doubt on his limited experience on Tongkat Ali (Eurycoma Longifolia) given the Huberman Tongkat Ali is not even clinically-tested, or used in clinical trials to back any health claims associated with randomized controlled trials on testosterone and other benefits.
Leveraging on other Tongkat Ali extract studies by quoting “it boosts testosterone by couple of points” in podcasts may seem less credible for someone like Huberman, especially when the person owns a stake in the supplement business.
Traces of magnesium stearate found in Momentous Tongkat Ali is used as a solvent during the Tongkat Ali extraction process may be safe but medical experts from Healthline believe that ingesting too much magnesium stearate may cause laxative effects such as bowel irritation and diarrhea.
The long-term liver risks of taking Momentous Tongkat Ali require further investigation given the addition of magnesium stearate found in Momentous supplements as evidenced in the Supplement Facts published by Momentous in 2024.
In fact, the pricing strategy of $15.96 based on monthly subscription offers a huge value to consumers as Huberman Tongkat Ali remains popular in the US as it is enthusiastically endorsed by one of the world’s biggest health influencer neuroscientists from Stanford University – Professor Dr Andrew Huberman, who also runs his own Huberman Lab.
Tongkat Ali may work to produce noticeable improvements in energy, testosterone or mild libido effects as claimed by Dr. Huberman himself, but the effectiveness of the Momentous Huberman Tongkat Ali extract has not been clinically tested, or scientifically proven by research studies.
This may send the wrong impression after hearing Huberman Lab for hours as most of the “testosterone optimization” protocols using Tongkat Ali were perhaps wrongly recommended, or the bioavailability of various extract technologies was never discussed in the podcasts.
Momentous Huberman Tongkat Ali does not provide technical details on levels of bioactive ingredients (eg: percentage of eurycomanone, eurypeptides, glyscopsanoin) to enable further review to assess the potency or purity of the Indonesian sourced extract.
Our analysis also revealed that Momentous Tongkat Ali is produced from 100% non-standardized raw root powder extract, which may not adhere to the potency marker set by the Malaysian Tongkat Ali Standards MS2409.
Huberman Tongkat Ali extract is non-standardized, which far less potent than hot-water standardized extract.
According to Head Scientist Dr. Annie George from Biotropics Malaysia, “Standardized Tongkat Ali hot-water extract has higher safety limit and is used in preclinical trials and human studies”. Our analysis showed 7 out of 8 randomized controlled trials on Tongkat Ali use standardized extract to validate its efficacy and impact on testosterone. This could be mean, non-standardized extract found in Momentous Tongkat Ali is less potent to induce any testosterone or health benefits when consumed even in high doses.
“Standardized Tongkat Ali hot-water extracts sets a new benchmark of quality standards which are known to have more health benefits”, she added.
In short, you may not get measurable or optimal results on your testosterone levels, strength or sperm motility by taking Momentous Huberman Tongkat Ali.
The first area of concern is that Momentous Tongkat Ali is made from Indonesian Tongkat Ali roots. Dr Huberman has sung the praises of Indonesian Tongkat Ali in several instances, calling it far superior to Malaysian Tongkat Ali.
Does this notion have merit? We think not.
Given the fact that the vast majority of human clinical studies and Tongkat Ali research from around the world centers Malaysian Tongkat Ali, specifically proprietary standardized hot-water Tongkat Ali root extract, the only conclusion we can really draw is that he is promoting the interests of his own brand over the vast majority of actual clinical research on Tongkat Ali benefits.
Malaysia is the only country that has published Tongkat Ali standards known as the MS2409, which sets a new quality benchmark that is not found in Huberman Tongkat Ali supplements.
Sourcing plays a key role in the quality and potency of Tongkat Ali supplements. Any manufacturer can source Tongkat Ali from countries like Indonesia due to lax regulations in the country and there is no accounting for whether this is grown in the wild rainforests, as premium Malaysian Tongkat Ali is, or in a more industrialized and polluted setting.
Momentous Tongkat Ali is composed of 100% raw root powder. According to some sources, raw powder is neither standardized to meet the threshold of bioactive compounds that are needed to our body nor is it extracted to fine powder extract.
One of the key ways to tell if a Tongkat Ali supplement is ideal for long-term human consumption is standardization and the use of a water extraction method. As it stands, it is more likely than not that Momentous Tongkat Ali is made with raw, unextracted root powder. While this may be sufficient for use as a traditional remedy, it is far below the quality of a dietary supplement intended to promote clinically tested health benefits to a discerning consumer base.
Learn more about the different types of Tongkat Ali extracts here.
Not only is raw root powder less potent than properly standardized and water-extracted Tongkat Ali root, it is also inconsistent in providing health benefits to humans. Huberman’s raw root powder supplement is, unfortunately, the cheapest and fastest way to make a Tongkat Ali supplement: a ground up form of the whole root, including all its components such as fibers, cellulose, minerals, and other unknown compounds, including potential ground pollution from where it is grown in Indonesia.
What difference does this make? With raw root powders, the potency of bioactive compounds can vary widely, depending on factors like plant maturity, growing conditions, and processing methods.
The efficacy of raw root powder can also vary based on individual absorption rates and bioavailability of active compounds. It is a far cry from the safety, efficacy and consistency of supplements using proprietary standardized hot-water Tongkat Ali root extract, which specifically concentrates and isolates health-enhancing bioactive compounds like eurycomanone, eurypeptides, glycosaponins, and polysaccharides, from the root and is widely clinically tested on humans.
Dr Andrew Huberman’s Tongkat Ali supplement by Momentous received a mixed-bag of customer reviews; some of which may consist less-than-authentic reviews that are deemed fake or less trustworthy.
According to our analysis of Momentous customer reviews, some consumers reported that there are wild inconsistencies in both the size of the capsules and the amount of root powder contain in the Momentous Tongkat Ali capsules. One consumer even went so far as to test this on his digital scale to prove this and has pictures showing capsules of varying sizes:
Some consumers reported side effects like severe allergic reactions and acne breakouts from taking Momentous Tongkat Ali supplement caused by potential allergens, impurities and adulterants found in most Indonesian Tongkat Ali extracts. In fact, contaminants in the polluted and heavily industrialized ground soil in Indonesia could also account for unwanted side effects:
There are also those that said that Huberman’s Tongkat Ali supplement did nothing for them, with some consuming a whole bottle only to feel more tired, irritable, with lower levels of libido than before they started.
Due to Indonesian extract used in Huberman Tongkat Ali, this similar negative experience was reported in another customer review of Solaray Tongkat Ali, another best-selling US-made Tongkat Ali brand that is popular on Amazon.
This may be explained by the inclusion of adulterants, allergens and adding of fillers or binders coupled with the low concentrations of bioactive compounds found in the raw Tongkat Ali powder sourced from Indonesia.
Of course, there are also good reviews, because despite the fact that it is sourced from Indonesia and unextracted, raw Tongkat Ali root powder has been shown in traditional use to still be able to boost vigor, energy, and libido, albeit only a fraction as effectively as properly standardized hot-water extracts made with clinical testing in mind:
Find out answers, consumer insights and how to use Momentous Huberman Tongkat Ali before making your first purchase.
According to various Huberman lab podcasts, Dr. Huberman stated that taking 200mg to 400mg daily of Tongkat Ali may deliver the optimal testosterone and libido gains. Whilst the recommended dose of 200mg to 400mg assumes one is taking a pure unadulterated root Tongkat Ali extract, pro athletes and bodybuilders are taking 400mg to 600mg daily to enhance their sports performance, endurance, energy and strength. In reality, the recommended dose of Tongkat Ali required by healthy adults varies between 200mg to 800mg depending on lifestyle, age, diet, and existing health conditions.
The best Tongkat Ali supplements are single-sourced from roots hand-harvested in remote Malaysian rainforests and made with proprietary standardized hot-water Tongkat Ali root extraction. This specific extract, conceived for further medical and pharmaceutical research into Tongkat Ali benefits, is the basis of more than 300 research studies and over 26 human clinical trials, including the two studies cited on Momentous’ page.
US-based Momentous may be a good supplement brand and their best-sellers like creatine, omega-3, and collagen peptides are very highly rated. However, Momentous Tongkat Ali is not associated with premium quality due to the untested extract sourced from Indonesia which deliver inconsistent testosterone and libido gains. Despite the affordable price tag and enthusiastic endorsement from paid medical experts, Huberman Momentous Tongkat Ali is not used by professional athletes, or natural bodybuilders as it does not produce any measurable energy performance, strength or muscle gains.
Momentous Huberman Tongkat Ali may show mild testosterone gains when taken between 200mg to 400mg daily, although actual results may vary significantly across various age groups due to the inconsistent bioactive ingredients sourced from untested Indonesian Tongkat Ali extract.
However, despite making testosterone health claims based on Huberman’s Tongkat Ali protocol, there are no clinical trials or research studies conducted on Momentous Tongkat Ali extract published by Momentous or any third-party lab tests.
In comparison to AKARALI Physta-derived Tongkat Ali formulation, other premium Tongkat Ali extracts are clinically tested with results showing 50% to 500% testosterone increases from multiple published randomized controlled clinical studies in the past.
We found no evidence that Huberman Tongkat Ali is performance tested by athletes to gauge athletic performance, making it less popular when used as a sports supplement. Huberman Tongkat Ali supplement is generally accepted his strong followers as many claimed that it boosts energy. However, its Indonesian-sourced Tongkat Ali extract is clinically tested on humans, nor to improve any athletic performance.
There has been no research published by Momentous themselves to claim that it enhances muscle strength, muscle building or boosts overall sports performance.
In conclusion, Momentous Tongkat Ali supplement performs well below other premium Tongkat Ali brands such as AKARALI’s Physta MIT-formulated standardized hot water extract.
Huberman’s Momentous Fadogia Tongkat Ali combo may not be safe when consumed in high doses exceeding 600mg of Fadogia, or when taken regularly more than 30 days. Past and present toxicity clinical human studies on various species of Fadogia showed damage to testicular cells, liver damage known as necrosis and cause gousiekte, a cardiotoxicosis of heart failure. Momentous Huberman Fadogia Agrestis supplement comes in 600 mg per serving which may exceed the safety toxicity limits, with severe reported side effects on the kidneys and liver. A recent study in 2023 showed chronic inflammation of the kidneys and liver damage when exposed to 50 mg/kg body weight, which translates to i.e 600 mg of Human Equivalent Dosage (HED) of Fadogia.
Momentous offers a taste of Tongkat Ali for new customers who seek to revitalize their health for the first time. If you are a big fan of Dr. Huberman and his Huberman Lan, most likely you want to buy Momentous Tongkat Ali that is sold directly from Momentou’s official website, Amazon, and via authorized Momentous original online resellers in Indonesia and India.
Our health expert Ilan Joffee from Core Supplement LLC concluded his final assessment and review of Momentous Tongkat Ali with the following statement:
Huberman Tongkat Ali is a brand that has gained much traction due in no small part to Dr. Huberman’s celebrity status, but it may not necessarily deliver the most bang for buck as the Indonesian-sourced extract are not clinically tested to deliver the optimal testosterone or libido gains compared to more established brands such as AKARALI.
Savvy UK and US consumers are better off paying slightly higher prices for premium, high quality Tongkat Ali supplements. These premium products work consistently, are ethically sourced, made from the highest quality clinically tested and science-backed ingredients, and most importantly, the use of standardized hot-water extraction methods with fingerprinting and chromatography have raised the gold-standards of Tongkat Ali beyond what is currently offered by Momentous, Solaray and other supplement brands in the US.

I am so much impressed by your blogs , very informative and knowledgeable, I have tried Tongkat ali from AOB nutrition. It does have the effect on my energy, enhanced so well but not upon my anxiety, I have heard of magnesium glycinate that it help in reducing anxiety. I will try .
Huberman has been involved in various controversies and isn’t a Tongkat Ali specialist. With these issues, why should we trust him?
Dr. Andrew Huberman is not specialized in herbal, Tongkat Ali nor he is a research scientist involved in any clinical studies or research of Tongkat Ali. On that note, Momentous Tongkat Ali is another commercial brand that is capitalizing on celebrity experts or doctors as a form of endorsement on its products. This explains Huberman Tongkat Ali is not well received by many Amazon customers, and took a enough beating from its growing customer reviews which are deemed to be fake or fabricated by paid customers.
Save your money! Huberman Tongkat Ali didn’t work at all for me. There are better brands out there.
Akarali is a clinically and lab-tested premium Tongkat Ali, ensuring high quality and efficacy. Stay clear of Huberman Tongkat Ali for better results.
We couldnt agree more after our deep-dive analysis of Huberman supplements and its ingredients.
I’ve tried Huberman’s Momentous Tongkat Ali product a while back and it was not potent at all. Just like some of the reviews, some capsules in the bottle were differently sized and others seemed to have different amounts of extract in some capsules. His Indonesian Tongkat Ali extract isn’t even clinically tested. What a waste of money.
If you’re going to get some Tongkat Ali extract, do yourself a favor and get the good stuff from Malaysia and not Indonesia. I thought Huberman’s Tongkat Ali was nothing more than cheap, non-standardized ethanol extract, but it’s just non-extracted root powder? Shameful. It’s a huge scam and he’s just using his celebrity to promote an inferior product.
I reckon Momentous is paying Andrew Huberman a big bunch of cash to put his name on a terrible product with zero clinical testing. Gave it a try last year and felt nothing. Go for quality Tongkat Ali supplements made from hot water extract and thank me later, lads.
We received similar feedback from consumers after taking Huberman Tongkat Ali supplements, as it is mainly hype and the quality is taking a huge hit due to untested extract that is sourced from Indonesian suppliers. Most Tongkat Ali suppliers from Indonesia opt for sub-par ethanol extract which are widely sold in the US.
Ok, I’ve tried a bunch of Tongkat Ali products. In my experience, Huberman’s worked better than Solaray’s 400mg, but it didn’t even come close to hot-water extracts like Physta – you can feel the difference like night and day. The wildest part? 200mg of Physta feels so much more potent than either of the 400mg generic formulations.
Huberman’s a huge scam when it comes to Tongkat Ali supplements. Got a mild libido boost from trying this product, but the effects diminished rapidly as the weeks went on. Either it’s not very potent or just not standardized at all. Wold make sense with the spotty and unpredictable results.
Bought a bottle of Momentous Tongkat Ali last year and didn’t bother finishing it. Thought I was hallucinating when I saw some capsules didn’t look the same. Eventally checked the capsules and some of them were differently sized and were different weights according to the digital scale I used. These quality issues really put me off and I don’t recommend it at all.
This is absurd! We cannot comprehend the quality issues that users are experiencing when buying Huberman supplements.
If you’re just looking for Tongkat ALi root powder I guess Huberman’s Tongkat Ali is alright for what it is. It’s definitely not clinically tested 0r standardized. Got some mild libido and energy effects from the batch I tried, but it wasn’t consistent at all. Am much happier with the effects of the Physta extract you guys sell! Been on it for more than 8 months now and I still feel amazing.
I’ve lived in KL as an expat for years and was outraged at Huberman’s uneducated take on Malaysian Tongkat Ali. Got my friend to bring me back a bottle of his Indoneisan stuff from the US to try and it was terrible. Proved my suspicions right. If you’re going to try some Tongkat Ali, get it from a reputable source in Malaysia!
Got myself a bottle of Huberman’s Momentous Tongkat Ali off Amazon a while back, and it’s really not worth buying. Gave me stomach cramps and headaches on and off. Save your money and get something pure and potent like standardized hot-water root extract if you want soemthing consistent and effective.
Sorry to hear you bad experience. You may perform better by switching to premium pure root Tongkat Ali extract. Used by UK runners and bodybuilders with no side effects, even after long term use. Please be extra careful when shopping for Tongkat Ali counterfeit supplements in the UK or in London – most contain excessive fillers or adulterants. Check for EUROFINS 3rd-party lab tested Tongkat ali when buying online in UK shops.
Layargaming I suppose Huberman’s Tongkat Ali is good enough for what it is if all you’re looking for is Tongkat Ali root powder. It’s undoubtedly not standardised nor clinically tested.
