Tribulus is worthless!

[TeeD_uP]

i am currently using alpha male as part of my t-stack i think they use bulgarian?/russian tribulus wich the most potent one who knows if tribex is stronger than alpha?

[resurrected]

I was sad to read Tribulus is the top seller for natural test. boosters on bb.com.
This article didnt have much to say about Tribulus....

Dont waste your money!

and?
I have been telling this for ages, but no one listens.

[CHUCK DIESEL]

This can go on for ages.....some tribulus is worthless, usually its the cheap tribulus (1 month supply for 4.99) but unfort. most trib based products are put out by companies that dont know what trib needs to be standardized for. I can go into a "what and why" on tribulus explaining what extracts to use and why but for obvious reasons I wont. If u take these products like optimum tribulus and NOW tribulus you may see an increase in libido and NO effects at like 3-6g day (as someone stated above). There is a big dif. in tribulus from China, India and the Bulgaria region.

[big_in_japan]

It may depend on individual body chemistry. Tribulus gives me a wicked kick in the pants and definitely fires up my T levels (I have to be careful that I don't get into fights!). I read the study -- 15 subjects total, only half of which (or less, they were assigned randomly and it doesn't say how many got it) took tribulus. Plus they took only 3.21mg per kg of body weight -- I weigh 90 kg., which would give me a 288 mg dose, but I've always used between 500 and 1000 mg. And it doesn't indicate anything more about the protocol (I always take it on an empty stomach).

So maybe it doesn't work in low doses. Maybe it doesn't work at all for some people. I guess I could do a one-subject saliva test on myself to see if it is really affecting my T levels, or if it just feels like it. Either way, I've been leaner, meaner and bigger on tribulus. Just my 2 cents.

BTW It doesn't seem to matter what brand. I started off buying the expensive stuff, but gradually tried cheaper and cheaper brands, and they seem to work just as well.

[TeeD_uP]

true true to much science is no good it comes down to the individual if you think in your mind its guna work chances are you beliving that is going to make it work....train the brain and then the bulk for real gains....mind power

[dfc]

Ok to start off l am 46 and l have read all the forums comments about trib and l am presently taking trib 650, 3 tabs per day and will let you know my view at after a sufficient review time. If NOT this supp then what others do u guys use and or suggest. Note that l have in the past (4 months) gone from 90kg to 82 kg but maintained muscle and yes l eat well, however l find it difficult to reach the weights that some of you guy may be reaching.

Example

Bench 70kg

Squat 80kg

Pull up 87 kg

db curls one arm 12.5 - bb 30kg

What the secret - If anyone knows???????

By the way like all the comments given thus far as trib is a supp well know and taken by many.

[TeeD_uP]

im no expert on the matter i can only tell you from expierince that trib does work, i cycle reguarly with but allso u should take zinc with it especely on your off days as zinc helps you repuduce t again naturualy after the trib as maxed your levels out...allso if you get acne from it i find zinc allso helps clear my skin....

zinc is a natural anti-aromatase and increases LH so it works well with Trib....well it is nec. for optimal LH production.

[javyn]

I can't wait to get my hands on some trib! Excited to see if it makes my erections even harder than zinc and soy lecithin do by themselves.

Should I take it every day? Or only when I'm getting ready to rock my woman...to the break of dawn?

[Juke n Move Jason]

No doubt, if your 19--TRIB is worthless, especially so if you take the weak saponin form. It's all about the protodioscin content that determines whether a trib product is junk or gold. It's the top seller on the site for obvious reasons--people use it and they buy it again, then tell their friends and they buy it. Pub med (the site sourced in the original post) has great empirical articles, but some of their studies are less than conclusive.

[knockoutartist]

first off for the yes or no people the answere is absolutely, tribulus works.

Now, for me im 22 years old and have been taking tribulus off and on for the past 3 years. I believe i've looked through and read every bit of info out there. My experience though tells the real story, I first want to point out herb form of tribulus is the worst, concentrate is good, and Liquid trib is the best. Secondly, the concentration of protosconoid and sapponis is vital. for an herb form you would need to take atleast 2000mg-3000mg a day for results. Problem is herb form caused me intestinal aching i would say, limited results but impact was there, for concentrated form i was taking 3- 1000mg tablets per day, if not 4 tablets some days. Results were good at this point, mentally i believe it helps, lets not forget test production starts in the diencephalon aka hypothalamus and pituitary gland house here. Muscluarity did increase as far as hardness and overall look. More sexual determination you could say as well. For liquid tribulus, results were best, most likely because it is easily absorbed in the small intestine compared the other two. Nutrex's vitrix is the only form i know of and have received better results with 1000mg as directed than with 4000mg of concentrate. With no side effects. The results were greater in all three categories, mental, physical, and sexual.
Now, i have also taken vitrix along with an extra 1000 mg of concentrate tabs which had awesome results or even herb form too!! The combination was amazing, Vitrix has the anti-estrogen which works so well i think its ok to take more tribulus herb style because Vitrix didn't need a high dose (only taking 1000mg a day as directed). I do not post much but i am a pre-med student with a 3.5 who does not go out very much and used to be a bodybuilding phene until i gave it up to pursue school and other activities. My research and experience is thorough so your choosing to trust my post is your own will, but make no mistake it is correct according to expereince and hours of research on this herb considering it is my favorite herb dietetically speaking. Yes i think marijuana should be legal..another story another day. Anyway bottom line is tribulus does work! I promise. If you do not think your suffering from low androgens then my advice is find another good supplement to take to fit your needs.. Supplementing is for finding an answer to the problem. So take creatine, it works too!! Now, Vitrix is the best tribulus on the market, adding in a 1000 mg concentrate or herb tribulus with it will give astonishing results. and those 2 forms can be found on bb.com for cheap. I reccomend the brand "Now" for that. Combine em and you'll love them. Furthermore, I have conducted clinical trial research via internet and have found great evidence on milk thistle!! Which i take as well!! Actual clinical trial evidence inside U.S labs on hepatitis and cirrohsis patients..amazing results. Vitrix is the thing to remember with tribulus until i find a competitor to beat it but the fact of the matter is they have done clinical research for years and now their newly released supplements are ahead of the game my friends. And remember i have taken atleast 6- or more brands of tribulus. I will not buy herb tribulus. I will buy concentrated form though if its cheap! to stack with vitrix or take solo. Safe and effective your muscles will look hard and lean and dryer. This is true. My supplement value chart would go as follows (whey protein, Tribulus, creatine, milk thistle, ginseng-sick vascularity,) Arginines are a joke when it comes to permanent gains and too much vitamin B-6 can cause PERMANENT nerve damage. And the average U.S. citizen has enough B-12 stores to last them over a year(these two are commonly found in high amounts with N-O supps.) The buzz you feel is actually a toxcicity side effect mainly excluding the caffeine which is ok. Sorry, off topic but i am a smart motha****a and feel i must express my findings and important info. The rep power is mis-leading because i am too concerened with my own studies to have time to post. As right now im taking a study break. Tribulus buy vitrix or take 4000mg of concentrate or for best results stack them... Peaceout men or "maybe" women- do they take tribulus, i guess so i would think it could cause masculinity. Oh yea the coolest thing about tribulus is that it increases interstitial cell activity which are the nurse cell to your testes, the creators of your androgens, this is proven so scientifically speaking if the form your taking is absorbed it will work. It's all about quality with suppelments, there is far too much **** out there on the market to even walk through without stilts and quite frankly its starting to piss me the **** off. If the the FDA is gonna take away our prohormones- which i don't take by the way. Then they need to make sure what we are taking is safe and free from toxic agents and disease which is highly possible and scary, on top of that more than half of the "supplements" are either unhealthy or simply do not work at all while we just keep shoveling our money out for em and stressing. I believe clinical evidence needs to be performed for content , accuracy , and safety. Especially when half the supplements if not almost all are created overseas in unknown conditions...but people like me and you, obsessed with fitness and physical appearance- me not so much any more, my genetics are adequate, don't think about serious illnesses or permanent damage from taking drugs because that thought slip right passed the frontal lobe(conscious thought) into the epiosodic memory(Long term memory) if not the semantic...Damn way off topic but very good thoughts and i gave my yes answer at the very beginning for all the haters. once again peace playa's n hata's

Idiot. "Vitamin B6 is usually safe to take for up to 200 milligrams per day. Intakes of more than this recommended dose can lead to neurological side effects." http://www.nutritional-supplements-h...e-effects.html

Sports (megadose) vitamins have 30mg (ast32x), 50mg (gnc) B6. 3 scoops of no-xplode has 75mg. So unless you're obviously pushing things, then you have nothing to worry about.

Saying arginine (vasodilator) is useless is like saying caffeine is useless since it doesn't contribute to protein synthesis. What a crock. That's not what it's used for. Use it for the intended purpose and you won't feel like a misled sheep.

And free form BCAA/EAA are usefull for us non-perfectionists who can't seem to get 4 scoops of whey in per day (be it lactose issues, work/school schedule, etc) or meat with every meal. There's also something to be said for instant effects if you didn't manage to consume protein 2-3h ago.

Oh, and tribulus studies where the experimental group gains no weight is like people being told to sit on the couch and then measuring their muscle gains. Why would you control for a variable which is required for the dependent variable to change?

This is exactly why our company won't sell supplements to people without a screening process and account approval first. All it takes is one person like the OP to make asinine assumptions about a supplement in general from a narrow study and BOOM - word spreads. This stuff isn't a drug! Its not going to get a guaranteed effect out of everyone. But to say its "worthless" makes you look like a jackass. Citing a weak study predetermined to slam the "alternative medicine" smacks of manipulation.

I'll say that its not at all necessary for a normal and healthy teenager or young adult, but I CAN say that a pure extract works VERY well, even for these younger people. I'm the nicest person in the world, but I got flat-out MEAN taking this stuff... I wouldn't recommend it for anyone that doesn't need it due to the cost, but its worked wonders for every single person I have EVER talked to that's used it.

WALL OF TEXT

[eazy57]

Longtime lurker here. Thought I'd chime in.. I just turned 40 and started taking tribulus on advice from a friend. Dosages definately make a difference, as well as type of tribulus you take. For me I am taking tribulus from Ultimate Nutrition.. I take 2 a day 1500mg. .I weight 145lbs.. It gives me energy.. and increases my virility. Thats about it.

Does it make you big.. not a chance.. but like me who would start to crash 3/4 into my workout.. it gives me the extra energy I need.

Like creatine that may or may not work for some, or any supplement for that matter.. if you don't do your research, and take it properly.. no supplement will work. And they can't possibly work without proper diet.

But as a newb poster.. I'm likely preaching to the choir.. Start with a good diet.. and supplement it intelligently...

[ptwa9]

and overestimating statistical bias of placebos, convenience being God.

[dirkwright]

I never get the wood anymore Seriously, this is no joke. I've been wanting to start a thread but was scared of getting bashed. I'm only 16 but I think my test levels are low. I'm gonna get them check'd next time at the docs office next month. Any suggestions? Help..

At 16 you should be nothing but wood in your sleep... I would see a doctor right away.

[valier]

In 18th Century there was a guy named Antoine Laurent Lovoisier, who changed chemistry by introducing his Law of Conservation of Mass. In short, the matter (mass) could not be made out of nothing. It is obvious that jdeity skipped his chemistry lessons. It is also obvious that he somehow believes that, in order for supplement (in this case tribulus) to wor, it is enough to just take it, while changing nothing else in training/nutrition regime. While it is true concerning training, it is obviously not true with nutrition. If you just take two or three tablets, or five or ten, while you consume the exact amount of food as always, how could it change you body mass? And yet jdeity thinks just that, that you could put on pounds of muscle out of nothing.
I'll tell you what happened after I started with this new tribulus. Before it, I was taking in around 220 g of protein a day. I tried to take more, and I did, but all the added stuff went to the toilet. Regardless of spreading it across 6 meals, I couldn't digest it. About week or so after I started using tribulus, I tried to increase the amount of proteins I consume. And it worked - I can take in around 300 g a day, without any of disturbances noticed earlier. The pure logic dictates that tribulus itself couldn't do anything if I haven't upped my protein intake. But before using tribulus, I was unable to assimilate so much protein. I could only take one scoop of WPC in 0.4 l of milk. I now can take two scoops in 0.5 l, three times daily, inbetween soild meals much denser in proteins.
And in the gym, my lifts were heavier. For months I pretty much stayed with the same weights, and then... This is the date from my gym log:
Deadlift:
October 5th - 162.5 kg X 8 reps;
November 4th - 180 kg X 8 reps.
Front squats:
October 12th - 135 kg X 6 reps;
November 7th - 150 kg X 8 reps.
So, if such uppings of poundage are a result of my good day at the gym, as would be noticed only by an ignorant person who assumes that I (or someone else) doesn't have a clue what I'm talking about. It's not just adding 10 pounds for a rep in a session, but adding 10 pounds for 8 reps.
And quite a placebo effect it is - I convinced myself to assimilate my food better. And there's a word I'd use to name your conclusions - but this is a place where it is expected of you to be polite.
Chemistry doesn't work that way, buddy - the cells and tissues are working in their own way.
So next time, instead of reading useless reviews and flawed studies, remember Lavoisier, and don't expect your supplement to work by itself.
And, by the way, read an interview with Dr Greg Ellis by Mike Mahler, in which Dr Ellis sums it perfectly - studies and their results.
jdeity, this is my final post on this topic, so you now may write whatever you like. I'm sure the members of this forum are analitical enough to try and see for themselves.

analitical??

[jamesyong]

I tried a box of Twinlab Tribulus Fuel Extreme, compliments of BB. It does increase libido but just a little. Nothing like tongkat ali which makes me leaner and skyrockets my sex drive.

[RMA08]

jamesyong,Does Tongkat ali really work that good?

[Riz]

I take NOW tribulus 1000mg... maybe 3 tablets (3000 mg total) per day. pretty much a year round thing along with my multi.

test levels were above the maximum end of the range last physical i got, but my test has always been near the max end of the range.

definitely feel greater 'weight' in the junk area when taking it tho. idk how to explain it... and the random boners never get old.

[RMA08]

Anybody else try Tongkat ali ?

[jamesyong]

yeah, it really worked for me. I felt leaner with the same diet and routine. Libido also went thru the roof. It really depends on quality, i tried the SciFit's Eurycoma 1500 EX but ti didnt do anything for me.

[jonnyboy92110]

None of these studies are really that credible, IMO, b/c

(1) 321mg for a 220 pound man is a low dosage.

(2) From the abstract, I can't see what type of tribulus. The key is to get a kind of tribulus with a high % of steroidal saponins. It could be a low % or the % listed on the label could be bunk.

So there's two issues right there. Maybe it works, maybe it doesn't. There's no definitive answer. Here's the most comprehensive write-up I've seen:
-----------------------------------------------------------------------

Before the September 1996 issue of Muscle and Fitness came out, few Americans knew of puncture vine, more commonly known by its Latin name, Tribulus terrestris. Used by Eastern European world-champion and Olympic strength and power athletes since the mid-'90s, the herb is purported to build muscle by increasing testosterone production.

Even today, only a small group of scientists, herbalists and doctors trained in Oriental and Ayurvedic medicine are knowledgeable about the plant, and little research has been done on it. The research that has been conducted is sketchy. Nonetheless, tribulus is becoming increasingly popular among athletes.

Arguments for the herb's effectiveness are based largely on a few inadequate studies and traditional use. Ancient Greeks used it as a diuretic, a mild laxative and a general tonic. Ayurvedic physicians have long valued the plant for its diuretic properties as well as its aphrodisiac qualities and include it in rejuvenative formulations for treating sexual problems.

In China, the herb is frequently used to treat a variety of diseases affecting the liver, kidneys, urinary tract (including urolithiasis, or urinary stones) and cardiovascular system.

Cross-culturally, tribulus is most often used to treat infertility, impotence and libido problems. The herb contains the steroidal saponins terrestrosin, dioscin, gracillin, kikuba saponin, protodioscin, neohecogenin glucoside and tribulosi. According to one paper, the saponins may be responsible for the herb's aphrodisiac properties.1

Some companies claim that tribulus can decrease fatigue, based on the results of an Indian clinical trial. Researchers investigating tribulus' tonic effects gave a preparation of the herb to 50 men and women who were fatigued and lacked interest in daily activities. Symptoms improved by 45 percent among subjects after taking the herb.2

But it was the search for safe, non-hormonal treatments for infertility and other reproductive disorders that inspired scientists at the Chemical Pharmaceutical Research Institute in Sofia, Bulgaria, to investigate tribulus in the mid-'70s. Based on the study results, Eastern European drug companies began releasing standardized tribulus preparations to treat sexual disorders as early as 1981.

The Bulgarian study, now out of print yet oft quoted by supplement makers, demonstrated that tribulus boosted blood levels of luteinizing hormone, a pituitary hormone responsible for regulating testosterone levels.

Luteinizing hormone "turns on" natural testosterone production in humans. Researchers didn't study muscle strength, however. Because the study is out of print, it is impossible to verify important details such as how much luteinizing hormone levels increased and whether it increased testosterone.

Another study, first published in the Russian journal Farmatsiya and mentioned in the 1996 Muscle and Fitness article by James Wright, M.D., reported that 750 to 1,500 mg oral doses of tribulus administered daily for 30 to 60 days increased testosterone levels of men suffering from impotence and infertility.3

The increase was not clinically significant and, again, researchers were studying only whether testosterone levels increased. They did not examine changes in muscle strength.

Tribulus on Trial
Some supplement company researchers are concluding that tribulus can influence muscle strength based on the Bulgarian and Russian studies. The problem with making this jump is that it is unclear how long either luteinizing hormone or serum testosterone was elevated and how much variation occurred among study subjects.

That is, did some men's levels increase a lot while others increased only a little? Did they all increase to the same extent? Unless an individual reaches pharmacological or above-normal levels of serum testosterone, increases in testosterone after taking tribulus may be meaningless. Thus, tribulus may lack the physiological punch to have a significant, long-term effect on testosterone levels.

To put it into perspective, serum testosterone levels also rise after a hard sprint workout or a weight session in the gym.

To get around this enormous obstacle, manufacturers are combining tribulus with other hormone supplements that purportedly enhance testosterone production. The steroid precursors DHEA (dehydroepiandrosterone) and androstenedione are promoted as testosterone enhancers, but they work differently than tribulus.

Both DHEA and androstenedione provide the raw material for testosterone formation, while, as mentioned previously, tribulus increases luteinizing hormone levels and therefore may affect testosterone production.1,3

Assuming a combination of the three works better than any one ingredient on its own, several supplement companies are producing "stacked" products that combine DHEA, androstenedione and tribulus.

The manufacturers claim that each compound's testosterone-inducing effects have been studied separately and have all been shown to potentiate testosterone production to varying degrees and by various mechanisms. This is a stretch, however, since published research on stacked supplements is nonexistent. Whether these stacked products yield better results remains to be seen.

DHEA and androstenedione are potent male hormones, and people should be cautious about using them. Anyone taking either DHEA or androstenedione should have regular blood tests and discuss the therapy with a health care provider. The assumption that DHEA, androstenedione and tribulus are effective training aids for bodybuilding and fitness training is, at this point, sheer speculation.

Is It Safe?
No significant adverse effects in humans were noted in the three tribulus studies that have been conducted. However, pregnant or lactating women should avoid this product, as should children, since it has the potential to significantly alter hormonal chemistry. Men with enlarged prostates should consult their physicians before taking the herb.

According to C.A.B. Enterprises, a tribulus importer based in Visalia, Calif., both acute and long-term studies in which rats were given more than 10 mg of tribulus per kg of body weight indicated extremely low toxicity.4

The bottom line? Despite the anecdotes, there is no conclusive evidence that tribulus enhances muscle growth or strength. For now, it is merely a fad. More research must be conducted on healthy people who have no libido or hormonal problems to see if tribulus truly affects muscle. It must be evaluated both as a stand-alone supplement and in combination with other supplements. And finally, the study results must be peer-reviewed.

This can go on for ages.....some tribulus is worthless, usually its the cheap tribulus (1 month supply for 4.99) but unfort. most trib based products are put out by companies that dont know what trib needs to be standardized for. I can go into a "what and why" on tribulus explaining what extracts to use and why but for obvious reasons I wont. If u take these products like optimum tribulus and NOW tribulus you may see an increase in libido and NO effects at like 3-6g day (as someone stated above). There is a big dif. in tribulus from China, India and the Bulgaria region.

can you expand more? i believe what you say. but i want to know more... are you saying NOW tribulus is bad or good?? what kind of diff. benefits are there from trib in china india and bulgaria??

Ok to start off l am 46 and l have read all the forums comments about trib and l am presently taking trib 650, 3 tabs per day and will let you know my view at after a sufficient review time. If NOT this supp then what others do u guys use and or suggest. Note that l have in the past (4 months) gone from 90kg to 82 kg but maintained muscle and yes l eat well, however l find it difficult to reach the weights that some of you guy may be reaching.

Example

Bench 70kg

Squat 80kg

Pull up 87 kg

db curls one arm 12.5 - bb 30kg

What the secret - If anyone knows???????

By the way like all the comments given thus far as trib is a supp well know and taken by many.

you still are at noob gains. Obviously you can cut and gain size. When you get to 175kg+ in bench and 225kg+ in squat is when it's hard to cut and lose fat. And you only cut 16lbs in 4 months, nothing crazy, still a good step but trib isn't what's doing it.
I feel it when I take it though, at least I get more "active" So I don't doubt it could work.

i take trib before i workout always...i feel that it makes my veins really pop out....is this the placebo effect????? might be but i like and will continue to use it

What's better of the three Tribulus or nettle root or even Aveva sativa for increasing Free Test?
