From malaysia here: Took a course on botany back in Uni and was told by researcher there that the non toxic part of the Tongkat Ali plant is the root, which has the characteristic walking cane shape, thus tongkat (walking stick/cane). However, manufacturers sometimes use the entire plant to save on cost, hence the toxicity.

I started taking tongkat Ali and ashwaganda and instantly felt less depressed and sluggish, felt better in the gym, and my body felt bigger and stronger and my workouts felt like they were actually building my body vs just staving off catabolism. The BEST thing I noticed was my energy levels were STABLE! I didn’t necessarily GAIN more energy, but I STOPPED CRASHING, I always feel good and normal. Which if your someone who has gone so long with seemingly low T levels, this is a HUGE benefit

I started taking it 3 weeks ago and my life has literally changed it's insane. I was always sleepy during day and now that issue is gone completely. My muscles look also somewhat bigger. I didn't do blood work but I am 100% sure my testosterone has gone up.

Been using it for years in Indonesia, always had great effects and zero negative effects at all.

I am 31 years old. It certainly increases and likely works through DHEA. I have done multiple bloods after taking. For me, LH doesn't move much, DHEAs surpass the range and total T increases between 20-30%, free testosterone hardly increases. Glad that there is finally good research on this to confirm what I thought. I am also not surprised that your body 'adapts' to Tongkat, it does this with most things as it attempts to maintain homeostasis. I have found that small cycling 5 days on a 2 days off has prevented tongkat from losing its impact and I have been taking it like this for a year now. We need good human research now on Fadogia Agrestis now, the combination of both these plants is very promising for increasing testosterone.

Considering testosterone itself is considered "toxic" and masculinity in general considered "toxic" I won't be taking this study seriously.

Very comprehensive review of the literature on Eurycoma / Tongkat Ali. I used to do product R&D for a company about 20 years ago, and one of the products I did included both LJ100 Tongkat Ali and a high protodioscin content (>40%) Bulgarian tribulus extract. Protodioscin is useful for increasing luteinizing hormone and, thus, testosterone, but Tongkat Ali was particularly useful for keeping that increased testosterone free / unbound. They seemed to work synergistically.

Tongkat Ali work effectively to boost testosterone and DHEA if it's taken with regular exercises (or ideally weight training + cardio). That is why Tongkat Ali remains as a dietary supplement, and should not be seen as a medicinal drugs. The misconception by most Tongkat Ali users is that they expect testosterone gain just by taking supplements, and assume their peak testosterone levels stay there forever! The reality is, our testosterone levels fluctuate throughout the day. And these caveats were not covered in any videos. Don't expect taking Tongkat Ali like putting fuel additives in your car, and expect the car to perform at its peak torque or BHP every time. Most studies on testosterone studies and clinical trials on Tongkat Ali in the last 20 years have sufficient evidence to show it may boost testosterone across men in various age-groups. There are more benefits than just testosterone, but the overall effect of Tongkat Ali is compounded by other hormones as well. The key is to manage the expectations of the end result of taking Tongkat Ali on overall men's health - measured by strength, energy, sexual desire, fertility, mental state and overall well-being.

Takeaway: should cycle T. Ali but no prescribed protocol as of yet. 4 weeks on, 2 weeks off seems like a good idea, buffering the off period with Ashwghanda, Fadogia Aggrestis, Zinc, etc.

Very informative, thanks. I have been taking the following: I'm 67, workout with kettlebells 5 days/week (40m each workout) and walk 30m x 3 times/week, try to keep a healthy diet on a 16/8 protocol (@60% plant based) and no alcohol except for an occasional glass of wine or a beer and 7 hours of sleep daily. My present cycle is: Tongkat Ali (Horbaach)1800mg/week + DHEA (various) 100mg/week + Tribulus (various) 1600mg/week. I started Tongkat @2015-16 but didn't have a rigorous workout plan and wasn't as healthy as I feel now. Therefore, I have become my own guinea pig. Results since 2019: increased lean mass and fat loss, higher levels of stamina, pleasant mood, better sleep, and active libido. In other words, I feel like when I was 40 something but leaner and stronger. My cycle goes on a 5/2 basis AND take a full month off everything every semester. I must add that I work as a data analyst online and my mind is alert all the time......

Educational video, thank you. I'm downvoting only because of the highly misleading title completely overblowing Tongkat toxicity for which you report that there is zero evidence at anywhere close to ordinary doses. The title is clickbait - it got me to watch but though I've watched other videos you've produced in the past I'm less likely to do so in future if basing my decision solely on what might be implied as subject matter from the title of any videos.

I've been supplementing with 600mg Fadogia Agrestis & 400mgTongkat Ali, for the past two weeks. I must say that I'm not as tired (during the day), as I was prior, and have no adverse side effects. I have low testosterone (tested), and will be anxious to get re-tested in another couple of weeks. I'm 72, weigh 150lbs, for reference.

instead of doing 4-8 week cycles you can do 5-2 day cycles, 5 days on and 2 days off and that will help to do so your body dont get used to the product :)

For me tongkat ali + creatine together have been game changer. However, I wasn't doing cycling but now I am going to. Thanks bro for this great info.

At 63, very few supplements help my energy levels. B-Complex helps but so does Longjack (Tonkat). I just don't take it everyday, I take it when I need it. Subscribed.

Ashwaganda fucked me up badly dude... Caused hyper sympathetic activation and my mind raced like crazy. I thought I was having a mental break of some kind and was worried I might end up in hospital. This was after one dose. I tries it again a couple weeks later and the same thing happened. Plus there is evidence it causes liver failures. So yeah be careful out there.

Hey, I had a blood test the 19th August done where my testerone was at 339 ng/dL. I have now been using Tongkat Ali for around 3 weeks and I will be getting another blood test the 1st of November. I am for reference 20 years old and relatively active. I will be doing a update when I get the blood result (if I don't forget it)

Tongkat Ali’s is the single best supplement for our endocrine system. In my 12 months experience with Tongkat Ali, I benefitted most from libido, sperm count and testosterone. Arguably, in order to maintain your testosterone peak levels, you need to take Tongkat Ali with regular exercises, avoid smoking or reduce alcohol consumption. And I agree that for Tongkat Ali to work optimally (and just like any other herbs), you need to cycle 4 weeks ON, and 1 week OFF. There are plenty of clinically tested Tongkat Ali brands with premium extract out there such as AKARALI.

My experience with Tongkat was I felt awesome and seen an increase in stamina, drive and muscle growth. But after a few months, my hair started thinning and falling out, which has never happened and hair loss does not run in my family. So a really bad side effect of this otherwise awesome herb. I am not taking it anymore.

Thanks for this. Everything in moderation is what I get from this. I may start cycling Tongkat Ali, I've pretty much reached a peak after having some initial improvement on taking it.

I would be interested in watching a video where you put together a list of what products you would take and in what cycles. For example, four weeks of Tongkat ali followed by four weeks of ashwaghanda etc.

That’s why Gorilla Mind recommended 3 weeks on, one week off to avoid any negative side effects.

I been taking tongkat/fadogia for a month and been feeling Tony the Tiger great. But after another month I'll switch to ashwagandha & shilajit for 2-4 weeks. Thanks for the tip!

if you think tongkat ali is toxic let me tell you about pharmaceuticals...

One insight for all, for all who does strength or even cardio training* (*everything less then 60 min, 100-15000m). start with leg exercises like squat, death lifts etc. It will trigger your natural testosterone level. Sow now you've for around 45min a incline curve of testo's available. No sex/mastrubation will enhance your testo level for 400%. and the last thing i only use is motivation, your dark/shadowside pain/suffering aggresion. Always focus on your healthy intake of food, focus on raw veggies, read green ones because oxygen is allowing THE POWER in your blood.

I’ve been taking tongkat Ali for 6 days now. Even by day 3 I felt a huge difference. My energy has never been higher, my diet and sleep have stayed the same. Lifestyle hasn’t changed but I have energy all day, more drive I feel on top of the world to be frank. I’m 17, I’m taking tongkat Ali on top of ashwaganda, cod liver oil, butter oil, creative, d3 and started smth else as of yesterday. The other things I’ve been taking for quite some time but nothing has had the amount of change tongkat Ali has on my energy

Guys. My levels are at 1,400 Ng/dl natural on Tongkat Ali. I have always been 800-1200 since my mid 20’s I’ve tested every year and I’m 33 now. Have been using tongkat for about a year.

I’ve used Fadogia and Tongkat for a year and I’ve had zero side affects. I finally took a break from them recently and still felt fine. I have my Fadogia and Tongkat on the way right now. I’m excited to get back on it.

Dude, i’m pretty sure it’s all the chemicals and plastics we’ve been exposed to all these years

As others have said, TKA is just fantastic for avoiding those energy crashes and it genuinelly was a game changer for me to consistently go to the gym on a regular basis, placebo or not it is working.

Please notice that toxicity concerns come from the extraction method used by companies….What I mean that the toxicity and DNA damage is related to the ethanol extraction not water distilled extraction

Excellent video! Great research and breakdown of the science. I have only made anecdotal reviews but this stuff really effects my performance in many areas and I feel effects that can't possibly be placebo! The title had me thinking I was killing more than my gains! Lol. I hope ppl don't take the title as the information, as they often do unfortunately!

Fastest click of my life. Good to know that the toxic dose seems unreasonably high. I really ought to cycle my Tongkat but I start to feel weak and lazy every time I take a break. Thanks for the summary!

thanks again for your work to deep dive into this material

I’ve tried all of the “natural” test boosters. None of them work.. except Tongkat Ali!!! I experienced effects after just 3 days, boosted libido, semen became much thicker, and I seemed to have a permanent “mild semi”, so was as if I had gained an inch while flaccid. Friends who I recommended it to also noticed pretty dramatic results. Definitely worth a try* although I did take double the recommended dose by accident, but I am 200 lbs, and pretty jacked, so my tolerance to most things is higher than your average person.

I’ve been taking Tongkat and Fadogia for around a month now and it’s helped a lot. I’m 30 but it’s definitely given me more energy during my training. Hopefully all stays well haha

I stopped taking tongkat ali because it gave me chubbies at the worst times. It definitely works in that regard. Had to do a sneaky belt tuck at the DMV

Most underrated KZfaq channel right here

No ums, no ahhhs, just pure information, absolutely marvelous

I take 1 Sigma pill after 4-6pm, 3-4 days a week. Best damn dreams, a small kick in libido, and puts me in chill mode. Reason for taking later in the day, cuz it will make me a bit lazy and i like my mornings to be productive. I do not recommend taking two pills a day, 3-4 days a week; which lead me to gaining 5 lbs. lost all 5 lbs taking less Sigma.

I'd like to share my feedback. I am 46 years old and was diagnosed with low testosterone. Initially, I declined TRT (testosterone replacement therapy). I have been regularly going to the gym for many years, but I am overweight. I have been taking it under medical supervision for three months now. After one month, my testosterone levels improved to 440. However, after three months, my levels dropped to 360. Over these three months, I adjusted the dosage a few times. I also took Fedogia A. for a few weeks. I supported all mineral and vitamin deficiencies with supplements. Well... I felt significantly better after one month. However, relatively soon after, I started experiencing headaches. After about two months, I had muscle and joint pain, and some occasional disorientation. So, I have now stopped taking it and will pause for a month before having my levels tested again. I strongly recommend listening to your body and not dismissing any symptoms.

Worked exceptionally well for anxiety, confidence, energy and mood overall. Stopped taking Tongkat Ali after one month cause it lowered my testosterone and spiked my estradiol and prolactin. Unfortunately, after stopping, all good effects went away. Same happened to my friend. Doesn't make sense but that's how it went for me and my buddy.

Great vid. Subbed just for your ability to present the facts without an agenda 👌

im 32yrs old and have had depression for my whole life. I am taking tongkat along with a bunch of other natural things. Im trying to go the plant and herb route rather than the ''chemical'' route(i just hate the way they make me feel). Tongkat doesnt help with depression but i can personally say i feel a very noticeable difference in my energy when i take it...

After taking Tongkat Ali + Fadogia for 4 weeks, I can confirm - it does absolutely nothing... nada.. I never changed any of my routine, diet or exercising, and after 3 weeks in, I even started feeling sluggish and somewhat slow.. I honestly do not think it does anything at all.

Unfortunately I was one of the ones that starting getting all over joint pain as time went by. Had to keep dropping the weight and increasing the reps which ended up making things worse. Had to take ibuprofen all the time. Stopped the T/A and joint pain went away. Try it but be aware of how you feel on it. Good Luck.

After 14days, go 5 days on 2 days off. This helps alot with the things you mention, like test going back to baseline after 8 weeks etc! Just because its all natural doesent mean you should take it nonstop forever without looking back. The body does not «adjust» as well when you cycle, this comes down to literally ANYTHING, coffee, ADHD meds, nootropics you name it.

Im 39 n just got a bottle. Not that cheap even im from south east asia(singapore) $60 a bottle of 60 tabs but for the first time i felt a tingling sensation "down there" n got a "morning wood" for the first time in weeks

i had no idea cycling it was beneficial i’ll definitely incorporate that info. thanks!

This was really interesting for me! I've tried Tonkat Ali a few times. I never experienced increase in strength or libido (though have had that happen with other herbs), but weirdly, it made me more extroverted! It also gave me insomnia.

Of course they'll say it could be a replacement for TRT, the current recommend levels of testosterone have been declining over the years. Soon they say water is a great alternative to TRT

Tried 200mg 2% by nootropics. Horrific gas, like diarrhea smelling gas for days. Spiked libido for 2 days then tanked Libido completely. Didn’t Make any difference to workouts. Creatine and whey protein will continue to be my daily, but tongkat did not work for me.

Absolutely effective. Can’t speak on toxicity. Much bigger during workouts. On the fertility side. Yep was bigger and thicker. Just giving my experience not trying to drive up prices.

My main issue with Tongkat Ali has been for prolonged periods I seem to have started to feel negative impacts and benefit from time off it. I also read it works by suppressing estrogen which is partly how you get higher free T elevation. I don’t know if this is true, but some people who have taken it say the estrogen suppression can lead to aching joints amongst other things. I am therefore going to be fairly respectful of it and only cycle onto it for a couple of weeks at a time and couple back off again too.

Thank you for posting this video. You have a new subscriber. Keep up the great work..

Very well done, it seems like moderation is key, and cycling on/off works best.

I love the way you explained it. Having said that, I prefer Tongkat Ali over TRT. But you need to know how to use Tongkat Ali to optimize the gains. TRT, despite being overly promoted by paid doctors, has severe side effects that cannot be tolerated - eg: permanent fluid retention that makes you look bloated after 2 years, stimulation of prostate tissue which is common, increased risk of blood clots, worsening of sleep apnea, decreased testicular size and others. Given the risk vs rewards, I would give Tongkat Ali a score of 10, vs a score of 4 for TRT.

Now that i look at it , this channel is not so bad as i have presumed well done

Addressing the point around the 6 minute mark about tongkat ali increasing T but not increasing LH. This is strange. Physiologically, as far as I know, there is no way to increase T production without an increase in LH. However, testosterone could be increased via suppressing aromatase, BUT, decreasing aromatase and thus decreasing estrogen, should also result in increased LH output. So this is definitely a strange phenomenon.

I consume 3grams at a time, and seem to be getting some good results. I also take it with stinging nettle root capsules, as they are an aromatase inhibitor.

Hey man I would greatly appreciate if you could make a video on your top vitamins/minerals everyone should be taking for overall health and fitness. I haven’t been able to find a lot of good science based ones.

From my understanding from listening to huberman. Tongkat Ali mimics or is an agonist of the LH receptors. So you wouldn't see an increase in LH on blood test results.

Fantastic video. Could you do a video about Fadogia and its potential toxicity as some discussions have been circulating about that.

After using tongkat Ali regularly for 4 months the only side effect I had was pain in the right upper abdominal area , mostly in the liver region just after consuming tongkat Ali. So now I will try cycling it

I'm taking the AKARALI brand. I'd call it life changing to say the least. I've cycled it for 4 weeks on 1 week off throughout a cut and its mitigated the catabolic effects; I went from 240lbs to 223lbs and i'd say visually I look similar in muscle content but have obviously decreased my body fat percentage by a lot. I'm even able to see veins once again all over. As far as the effects it's made my libido go up especially the first few days of a cycle, energy improved, better recovery and strength gains despite being on a cut. The only side effects have been occasional sensitivity in the nipple, like uncomfortable amounts; this only happens for the first few days and with no visual gyno development i've seen no reason to discontinue it.

I have tried a couple of different types of Tongkat Ali both at all sorts of doses but have found it gives me a Negative effect on libido and my man hood in general etc.. Fadogia I found taking it every other day helps improve all of that and even my energy levels.. and certainly helps with the amount of semon production etc too!.. and I have been doing this for a couple of weeks now and it seems like the same effects still! I do seem to get a tolerance very quick for most supplements! So fingers crossed I have worked out something now with Fadogia that will stay the same! 🤞

Even if they’re toxic it don’t matter so is all the food they feed us at Walmart it can’t be any worse at least we get a test boost😂

Hey Zach, Love the informative videos that you are providing for everyone on all the different types of supplements out there. Although, I was wondering if you could do some videos on different supplements that would be recommended for women. Looking forward to these type of videos for all females out there and also to recommend the females in my family.

I took 50 doses only on workout days and my irritability and anger went through the roof. I had sleep disruption, and nerve pain. I had to stop taking it immediately. I did see weight room increases and and body composition improvements, so it wasn’t all bad.

Tongk Ali works ( the main pathway) by increasimg the free hormone level by reducing the link with SHB. So, the ideal would be to use Tongk Ali with some other substance that stimulates LH and FSH, avoidind, this way, the negative feedback that the free testosterone would cause in the brain.

At 75 years old I start using it and it seems to work, And cycling on and off seems to make it more effective for me anyway

I was taking some but had some wierd brain fog, so I just take Shilajit now. Definitely feel clear headed and a strength boost with it

Yea i think shilajit is the move for a natural T booster , it seems to have the lowest possibility for substantial side effects

From my research, it's important to cycle Tongkat Ali (5 days on, 2 days off) because you will otherwise have negative side effects from estrogen deficiency.

Hi Zach, thanks a lot for all these inputs! I've already tried the 2% powder from ND (I bought 2x30grams jars) 200mg per day , nothing, then tried 400mg per day... for several weeks... not much obvious results (but not blood test, that's true) I've hence started 10 days ago another trial with the 10% version , still from ND. Nothing magical so far. I read that maximum results occur after 2 weeks, so I'll be patient... anyway... I would appreciate your views on cistanche ? it seems that it can be stacked with Tongkat quite nicely ? Thanks again ! 🙂

Tongkat Ali really, really works. But I notice negative, withdrawl like effects if I take it for more then 2 days in a row. I once took it 2 weeks in a row (1g of 1:100 extract per day in 2 doses), and the negative effects were quite noticeable. I would compare it to a weekend of heavy drinking and partying. I also think that Tongkat also notably increases dopamine production, which is a important factor in its "crash" negative effects.

10 days on 5 days off. This is the ideal cycle.

I will boil it tomorrow & drink if I find one. It is toxic in high doses. Just take the normal dose. Will make a video on it when I have time.

Can you please explain the difference in dosing and effectiveness with using the 2% and 10% eurycomanone?

I'm a 41yr old woman and I started taking it because of my super low T level. I've been on it a month and I've noticed a big difference in my libido for sure. I'd tried compounded Testosterone and it worked for like 2 months and then stopped.

I got the 10% from ND. It's effective, feels like it helps me with bigger lifts. Probably the only decent supplement outside of creatine.

I know topics are often nuanced, but given how people seem to act online, glancing over things, short watching videos, etc. It may be good to offer some timestamps and a conclusion

I read so much anecdotal feedback that seems to indicate low-estrogen side effects. If it's mechanism of action involves robbing Peter to pay Paul (in a hormonal sense), I wouldn't see it as a very good supplement except for people suffering from high estrogen.

The ending was epic, I’m glad it turned out to be good news. I’ve been taking it for 4 days already, 400mg, and I love that it gives me energy, and it makes me motivated to do even the most basic things like go to the gas station and grocery shopping lol and for some odd reason it kinda changed my mood? I seem more happy and less worried about certain issues. I don’t even know if that’s related to Tongkat. I do have a question, the brand I got says to use it for 5 days straight, then take a 2 day break.. then continue for another 5 days, and repeat that cycle. Can I just take it every day?

The matrix calling herbs/roots as toxic, but seems to be that none of the pharma drugs aren't toxic

Gave me suicidal depression. Stopped taking it immediately.

Hello Zach! Congrats for the amazing content! One question: You mentioned cicling Tongkat ali with other herbs, such Fadogia agrestis. However, in another video you said it's toxic. Have I lost another video? It has changed or it is not safe to take for long periods? What's the catch?

Hello Zach. Thank you for this video. You said that the toxicity of Tongkat Ali could start at 30,000mg per day. But the study shows 2,000mg/kg bw. Nobody, but a low age child weighs 15kgs or less... And in a lot of products, we have 200:1 concentration with a 200mg or 600mg dose (so 40,000mg and 120,000mg of active ingredient!) Or maybe i missed something😐

Tongkat Ali has been getting a lot of attention over the past year or so, and for good reason. It appears to be one of the more promising supplements that may actually increase testosterone, even in young healthy men. However, there is some recent research that has surfaced over the past year that is worth diving into.

Could you recommend using tongkat ali + Ashwagandha or SHILAJIT at the same time for workout purposes and increase testosterone levels?

Been taking ND's Tongkat 10% for 2 months, no side effects at all for me, I feel amazing on it, no need to cycle it says ND and Andrew Huberman. :)

Worked great for 3 days. I felt like I had superpowers but my body adapted extremely fast and by day 4 or 5 all benefits were null

i using this Tongkat Ali about 30 years already and still good to go. Nothing happened to me till now 🤷 and this roots is for regain your energy same as Ginseng roots too.

Been trying to dig into these herbs a bit. Sometimes it seems like it would be easier to go on trt. Such a tough decision to make though

Very interesting, thanks for the info. I also saw on another video that TA frees up more of your testosterone and keeps it from binding, I'm not sure what the exactly mechanism is that causes that but I just thought that I'd point that out. Personally for me I just started taking it a few days ago because I can't do trt because I have a blood clotting disorder trt raises your hematocrit so I'm hoping that TA will help me raise my T levels even if it's a few hundred points but I will still follow up with blood labs after 2 months on TA.

That was very interesting and well presented. Thank you.

Great channel, just discovered it!

thank you for this great video, I have been following your videos on testosterone optimizing videos religiously. I have a quick question, a bit out of topic though. Can alpha gpc be taken everyday? I have heard a 25 to 75mg dose per day for maintenance is not a bad idea; or you are of the view that it should be cycled?

Thanks for the video. For me I think tongkat was blowing out my estrogen immune response (also a problem with armistane) and I had severe cold sore breakouts every 2 weeks. It should be noted that I was also on nicotine so the anti-estrogenic effect was possibly stacked.

Age 70 here, think I will try tongkat ali soon
