Is Tribulus A Testosterone Booster… Or Not?

Brace yourselves - It's time to reveal the truth about this elusive supplement!

Supplement bottle opened with some capsules spilled

Questions my friends, these bloody questions! They play a significant role in our daily lives as we constantly question everything, even things which are question-proof and solidly undeniable. Delivering on point answers is always a delight – I shall do my best to deliver!

As we’re on a testosterone boosting topic here, I’ll be poking at our common pal, the legendary Tribulus Terrestris, and my task at hand will be to provide an answer to the simple question: Is Tribulus a testosterone booster? Quite simple, yet ridiculously complex query – although giving it a single word answer IS possible!

I hope you’re already familiar with the fact that I simply love quotes from wise people. In this regard, It just couldn’t be any more appropriate to insert the brilliant phrase from “Hamlet” by Mr. Shakespeare himself:

“To be, or not to be: that is the question”

– William Shakespeare, Hamlet

Undeniably we can relate this quote to good old Tribulus. So much controversy surrounds this herb, unlike bananas, which are very testosterone-friendly. No, really, just ask two different bodybuilding enthusiasts or just general gym goers and the chances are that they’ll have different opinions about Trib. First and foremost though:

NOW Sports Tribulus 1000 mg,180 TabletsWhat Exactly Is Tribulus Terrestris Anyway?

Tribulus Terrestris is a flowering, annual plant and you can find in a lot of places all over the world. It’s got an awful lot of a.k.a’s such as Goat-head, Puncture vine, Cat’s head etc.

Some of these nicknames probably come from the fact that by the end of spring, the fruits of Trib dry out and transform into solid seeds with little but troublesome spikes. And so on, and so on… until we collectively fall asleep from boredom!

I’m positive that none of this can help you on your T boosting endeavors, however, It was something I wanted to give some attention to. After all, you have to be familiar with what exactly this herb is, especially when it’s linked to higher values of The King of Hormones.

Nonetheless, Tribulus is one of the more well-known ingredients, used in various products and dubbed as one of the most popular, natural T-enhancers. Chances are that you’ve heard about it already – it’s that popular, really. Or at least the bodybuilding community wants it to be that way!

Enough with all the general info about this plant, want to move onto something more specific when it comes down to boosting your testosterone levels naturally? Same with me!

Does Tribulus Increase Testosterone?

In short – no! Everything about the main ingredient of MANY testosterone boosters out there just seems so vague. But above all, scientific evidence clearly shows that there’s 0 (zero) correlation between supplementing with Tribulus and experience an increase in testosterone levels.

Also, there’s contradicting data all over the web, as well as different folks who have contrasting opinions about its alleged ability to optimize our masculinity.

Now, there’s now something that’s really puzzling you – who do you believe after the massive piles of conflicting information concerning this plant? Let me throw some info on research was already done on the subject:

  • Twenty-one fellows from 20 to 36, one controlled group, one placebo. Conclusion? No direct or indirect link between Tribulus and it’s supposed androgen-activation traits (1);
  • Test subjects ranging from 30 to 50 years of age – no relationship between Trib and an increase in testosterone (2);
  • Young men exposed to resistance training plus a supplement which contains Tribulus Terrestris extract. Results were crystal clear – no elevation in serum testosterone concentrations (3).

Anyone with the slightest amounts of common sense would realize that this is some HUGE evidence, that our friend called TT (you know what this stands for) might not be the best option for natural testosterone optimization. Although I think they should’ve used Chuck Norris as a test subject – anything would work on him!

In all seriousness though – the scientific data is conclusive. I mean, come on now… at least ONE of the guys that participated should’ve at least had a tiny, little spike in testosterone production. Haven’t these people heard of placebo, or what?

But hey, let’s flip the coin and take a look at the other side of things…

Are There Any Studies To Suggest That Tribulus Can Actually Increase Testosterone Levels?

Interestingly enough, there are. Research conducted on monkeys shows that Tribulus can indeed boost their testosterone production. And this exact study is most likely what those defending Trib will show you to convince you that it works.

As for the actual study, in 2008 researchers (4) decided to research this mysterious herb by using animals as test subjects (no idea if any of them got hurt during the study). No clue whatsoever why anyone would consider such weird research, but there you go!

Firstly, they used Trib Terrestris intravenously. Secondly, the mammals tested did experience some elevated T levels with the help of Tribulus Terrestris. Thirdly, hmm if something sounds too good to be true, It’s because IT IS!

Tribulus could work for mammals (in this case, monkeys), but human data is controvertial at the very best

Unless you are a baboon… actually I congratulate you with all my respect if you are, because you are clearly on the internet, reading through my post about the worth of TT while ordering dinner through your mobile app. Salute!

So if you are a human being, chances are this study means jack shit to you, because it’s completely IRRELEVANT! I doubt you would want to inject yourself with Tribulus even if you want to duplicate the conditions of the research conducted on animals.

Does That Mean That Tribulus Is 100% Worthless At Boosting T Levels?

Yes, I believe so. Sure, it might be used in certain parts of the world as an aphrodisiac, but according to science, It’s safe to say that this herb will most likely not make you more masculine.

However, leaving relevant scientific data aside, there are probably guys out there are happy with the effects of TT. If you’re so curious and would like to know if it’ll work for you (most likely not), then by all means – do give it a try, just for the sake of it (at least it’s safe to use).

Maybe you know guys personally, who swear by Tribulus Terrestris. People who have past experience with taking Trib and making all kinds of gains, achieving firmer erections, feeling more manly, shredding lard plus a lot of other factors associated with an increase in androgenic activity in the system.

What works for you, might not work for others (or vice versa)

Repeating the same old cliche that everybody is unique, what works for you might not work for another person and so on could very well sound over-used, but guess what? It’s the truth itself! Some folks really do SWEAR by the effectiveness of that stuff.

Anyway, my position will remain the same towards dubious T boosting ingredients (as opposed to ingredients like D-Aspartic Acid that I’m personally a fan of) as I want to share with you only the most valuable compounds that you can buy, so that you can reap the most benefit from testosterone increasing supplements.


From a personal perspective and according to science (5), Tribulus Terrestris might only be useful if you want to help your little fellow stay stiffer during late night encounters. Do I consider it an effective testosterone booster? NOT by any stretch of the imagination!

I’ve used Tribulus on a few occasions myself with mixed feelings. I’m talking about both stand-alone products which contain only this herb as well as combined supplements with different components, one of them, of course, being Trib. To make it fair I would only judge my past experiences with those only containing the aforementioned herb.

Basically, everything positive about it can be wrapped up in the fact that I didn’t receive any unpleasant side effects from using it. As a MOST welcome bonus though, I do remember that my bedroom weapon was being more powerful than usual – also sperm count was definitely on the rise.

In fact, my all-time favorite testosterone booster (read my review about it here), used to have Tribulus in it when I first tried it and I felt superb in every possible way (including the bedroom). Besides, There’s a study which suggests that a potential libido-stimulating aspect of Tribulus does indeed exist.

A stiffer rod could be well-worth it when it comes to utilizing this herb. Yet the T-boosting side is surrounded in a shroud of mist.

Overall though in terms of more alpha male attitude, more gains (muscle mass) and/or strength and even the slightest adjustment in body fat percentage it was a disappointment for me. Honestly guys, after all the HYPE about Tribulus I’m sure that my strong mental desire for it to work (placebo) could’ve saved the day… but to no avail.

And if any of you who has a success story (or just any story) with this mega-popular herb, feel free to share it by leaving a comment!

  1. I too am a gym rat searching for a legal testosterone booster.I have suffered unpleasant side effects from taking free products offered over the internet that were suppose to boost my testosterone. When you say tried Tribulus a couple of times are we talking taking the supplement for 3 days or 30? Did you hit the gym 2 times a week or 5? If you do find a legal supplement to boost testosterone that is not expensive as hell I would love to hear about it.

    • Welcome to my site Larry!

      Sorry to hear of your misfortunes related to garbage T boosters. I would never use anything for free personally – quality comes at a price.

      My Tribulus experience has been mostly using bottles which are generally a 1 month supply. I was very active in the gym in every case where I was supplementing with Trib so you I got that covered.

      Be sure to check my site regularly as I will be posting personal reviews of testosterone boosters which I had tried myself and trust me – there are some that do WORK and will not cost you a fortune.

  2. Hey Simon,

    I love your writing style! Way to drop a Rambo reference in there, too.

    Reading your article, I can see why there may be so much confusion over certain products and what they do, or what they DON’T do. Your site is going to be a big help with that.

    Keep up the great work!

    Best wishes,


    • Hey there Kevin and welcome on board!

      Thanks for the kind words. Haha, always been a Rambo fan so I couldn’t resist.

      Indeed, I certainly hope this site is of help to anyone struggling with the mythical “optimal testosterone levels” voyage.

  3. Hello Simon,

    Very interesting article and I’m glad to hear that you even tried the product and gave us your review. It’s good to hear that there’s no side effects. Your articles will be very helpful in making informed decisions on what to buy and what not to buy. Should people who take diabetes medication use this product?

    • Welcome, Rich!

      In the case of Tribulus – there are no side effects, but more accurately I must say that there is NO effects period. At least from my personal experience.

      About taking prescription drugs and using a Tribulus-based supplement at the same time… I don’t see why it would be a problem if it’s only Tribulus in the product that is. This herb doesn’t mess around with insulin or insulin sensitivity so there should be no correlation whatsoever.

      Cheers and God bless,

  4. Hi Simon,

    Great site and such a polemic topic to tackle – Tribulus is it or is it not a T booster. I have actually read a lot of data relating to the herb and its relationship with testosterone.

    My own view (based on reading a lot of clinical trial reports and the data to back that up is there if you look for it) is that this herb does not enhance testosterone, however, it most certainly enhances the number and density of androgen receptor cells in the brain helping users to experience the effect of increased testosterone “as if” it was actually increased. helping the body to make better use of the pre-existing test that is already in the body.

    That for me explains the T boosting effects experienced by Tribulus Terresteris users.

    Nice one Simon, rather polemic topic well handled!

    • Hi Derek.

      Good to see a well-informed fellow joining the action! I’d guess it’d be pointless to repeat my stance on Tribulus, so instead, I’ll just say that YEAH, I agree with you, buddy. The whole subject is polemic indeed, but this is where truths are born out of, right?

      I’ve been told that Bulgarian Tribulus is the best one out there simply because it boasts a bigger number of steroidal saponins than any other product containing this herb. I’m yet to try so can’t report about its effectiveness, yet!

      Cheers and God bless,

  5. This is a very interesting article. I must admit that I have never personally considered trying any of these products. However, I am very glad that you have shed some light on this type of supplements.

    It is good to know that all the hype is not necessarily what it appears on the surface. I think many middle aged and older men fall pray to the ads without doing any real research into the products.

    You have gone a long way here to do that for the rest of us. Thank you for sharing this information.

    • Hello and welcome.

      Not only middle-aged or older folks but EVERYONE in general fall victims to commercials. It’s just how it is – ads are created in a certain way so that they can lure us in.

      I’m glad you feel more confident about Tribulus now – this is why I’m writing and sharing this information with you guys.

      Cheers and God bless,

  6. Hey, Simon

    There are so many of these type of products on the market and all claiming to be from natural stuff. Tongkat Ali (therapeutic herb native to the Malaysian rain forests) is the most popular stuff here. Some claimed to its potency while others had not been too lucky. I guess they could have bought the diluted stuff.

    Anyway, back to your awesome review, I have not heard of TT and I must admit I will not be trying TT or any of these products. BUT if a reader is keen to buy, can you put the link to direct them to a site (Amazon?).

    Thank you for sharing this interesting and fun review.

    • Hello!

      Good mention about Tongkat Ali, kudos for that! Something that I should try in the near future and expect a spicy review of it.

      Tribulus is a very debated ground and you’ll likely run across various opinions about this herb. My personal view is obvious and I wouldn’t change it. However, if you consider it sometime in the future, do keep in mind that its way better to utilize it in a multi-ingredient testosterone booster, as opposed to just taking Tribulus Terrestris on its own.

      As for a link to a TT product on Amazon – NOW Sport’s Tribulus is VERY decently priced and it has 90 tabs. Sounds like a bargain for anyone interested in trying TT personally.

      Cheers and God bless,

  7. Awesome read!
    I became interested in low-t because of my age. I am 45 years old and I understand that testosterone lowers as a man ages. The fact is that I’m doing and eating things that are helping the process along instead of fighting it. I always heard that a man’s muscle mass lowers with age and I have noticed that happening. The truth is that I haven’t been doing enough to fight the problem. I assume all of the information on fighting low t becomes more important as we get older, Is this true? It seems difficult to change my way of living just because I became another year older but it seems like it is inevitable.

    • Hey and welcome to the site.

      You’re spot on about the fact that we men do experience a steady decline in testosterone levels as we grow older. The rate of decline is about 1% every year after we hit thirty – not a huge amount, but it can become noticeable as the years roll on.

      And it is of vital importance to do what you should (except steroids) in order to keep your masculinity as optimal as it can be. So motivate yourself and start adjusting and tweaking bits and parts of your lifestyle so that you can be as manly as possible, for the longest time possible.

      You can do that with the help of this website – feel free to read every single bit of info here.

      Cheers and God bless,
