Tribulus : Does it increase Test levels in humans?

I don't care about the studies done in mice, those studies have shown false for humans.

This study you posted:
TRIBESTAN EFFECT ON THE CONCENTRATION OF SOME HORMONES IN THE SERUM OF HEALTHY SUBJECTS

has nothing to do with what I am asking.

That "study" Ross is posting isnt a study by means. Its an article written to look like a "study" by a manufacturer (Tirbestan) with false and doctored results.

I think we both know Tribulas....And thats any ****ing %, or any spectrum of steoridal sopinoins, does NOTHING for endogenous testosterone production.

The new formula has the Tribulus taken out and extra Testofen added.

A recent study on tribulus' effect on primates, rats, and rabbits. The study was done for the treatment of ED, however it did show a 25% increase in T levels. While this doesn't equate to increase strength necessarily I do enjoy the aggressive boost that I get from tribulus in the gym. A big problem I have with lots of these studies is that they use a f**king bunk amount of tribulus. 30-50mg/ kg of bodyweight isn't anything. When I take tribulus I take between 4 and 6 grams a day and definitely notice a difference. It amazes me that dbags like conciliator like to hate for no reason.

The hormonal effects of Tribulus terrestris and its role in the management of male erectile dysfunction--an evaluation using primates, rabbit and rat.

Hormonal effects of Tribulus terrestris (TT) were evaluated in primates, rabbit and rat to identify its usefulness in the management of erectile dysfunction (ED). TT extract was administered intravenously, as a bolus dose of 7.5, 15 and 30 mg/kg, in primates for acute study. Rabbits and normal rats were treated with 2.5, 5 and 10mg/kg of TT extract orally for 8 weeks, for chronic study. In addition, castrated rats were treated either with testosterone cypionate (10mg/kg, subcutaneously; biweekly for 8 weeks) or TT orally (5mg/kg daily for 8 weeks). Blood samples were analyzed for testosterone (T), dihydrotestosterone (DHT) and dehydroepiandrosterone sulphate (DHEAS) levels using radioimmunoassay. In primates, the increases in T (52%), DHT (31%) and DHEAS (29%) at 7.5mg/kg were statistically significant. In rabbits, both T and DHT were increased compared to control, however, only the increases in DHT (by 30% and 32% at 5 and 10mg/kg) were statistically significant. In castrated rats, increases in T levels by 51% and 25% were observed with T and TT extract respectively that were statistically significant. TT increases some of the sex hormones, possibly due to the presence of protodioscin in the extract. TT may be useful in mild to moderate cases of ED.

It's junk. Save your money. Besides from multivitamins, omega-3 fish oils, protein powder (with high carbs), creatine, caffeine, thermogenics, and mixed green products, it doesn't work.

It wont make up for hard work and good dieting.

The observed increase of 25% was [solely] attributed to the fact that the rats were castrated --> hence the reason why this increase was not observed in the normal rats [despite the fact that the normal rats were administered a larger dose].

It is when it's intravenous administration --> hence the significant increase of 52%.

Agreed. This is especially true with orally administered Tribulus terrestris.

Yeah ok.... so explain the observed clinical potential in various studies, for Tribulus terrestris in erectile dysfunction? *silence*

[BigKrabbe]

No Hype do you feel that tribulus could some how affect the adrenal cortex's androgen output, and not actually effect your balls? Because how is a rat with no nuts going to produce test besides the adrenal cortex's small androgen output? I would love to see a proper study on tribulus, one using true proteins 70% saponin trib I love that stuff to death!

Trib definitely increases my libido.. A definitive study would be nice to see, one using humans anyway..

Never said it would make up for hard work, lol and dieting? whats that? I'm on the see food diet and I eat everything. All these bitches who weigh 190 at 10% bf are like should I cut for summer?? NO you should eat more, quit being such a nubile pussy and not worry about that bull**** abercrombie body. I train hard as hell but don't even try to tell me that you wouldn't like feeling more amped up or aggressive in the gym. Just because I am a proponent of trying to raise my test levels doesn't mean I don't work hard. Not trying to flame, just saying. Lol and brotherwolf, just cause your hairy doesn't make you a wolf! I really love all the scientific studies not only for tribulus but for lots of different substances that use such negligible amounts of whatever they are trying to test, and are for some reason seen as "legitimate". Thats kind of like taking 5 grams of protein a day instead of 1gm per lb of bodyweight, and saying protein intake doesn't positively effect muscle building...

Great point. Just because its a study doesnt make it relevant.

There are different quality levels of trib products just like all other products. Most companies want to make it as cheap as possible and make a killing on it. If you use a quality trib product with heavy doses of Sap and Proto in it, they work and work well...in my opinion. Finding a study to prove that will be hard for the reason stated above none of them that have been published use proper doses.

Strange...your "proof" doesn't back up your claim in any way...

6 of 9 test boosters in one news article doesn't, in any way, represent all the test boosters that are out there. Please just go away.

HAHA even if they were spiked with androstendedione, it wouldn't have done nearly anything in the pixie dusted amounts it would have been in. Besides having a terrible conversion ration of what somewhere around 5.7%? And nothing about that article has anything to do with tribulus...some test boosters have them some don't. Rash generalization my friend.

no conspiracy read the article they are talking about traces/contamination

supplement companies will put saw dust in their **** before they use expensive steroids... think about it man steroids are more costly than ground herbs.. the article proves absolutely nothing , no names no product is ever mentioned . As far as we know they could be talking about protein powder
or multivitamins

[conroeguy34]

I have taken Tribulus a few times in the past and each time, about week 2 or 3, my balls start to ache. The discomfort is mostly noticable at night. I can't take the stuff, it takes a week for the feeling to subside. Anyone else have any problems with it?

[MrJacko03]

Until there is proof through clinical studies (humans) that say it works, my opinion is NO ;o)

1. If it actually worked, every single doctor would use it instead of hrt, right?

2. Why is it (in this forum) that every single time something shows a bit of results with rats, mice etc., then it automatically means that it works on humans?

I knew a woman once who was working at NOVO and she said that what works on mice, rats etc. only works on average 1-5 out of 100 on humans and that could even be a strech. She told me then, that you could under no circumstances just conclude that the effect would be the same in humans. At least not if you are a serious med company.

Isn't that what the supp.companies do all the time?

[legdoctor]

Guys, i dont want to bother you too much, its just that alot of people say it works and it doesnt, so im wondering why the hell is it banned in Ireland if its fairly safe??
Any product with trib is banned in Ireland, i brought a lot of it back from Poland last week and everyone at the gym was offering me anything from 30-40 euros for a bottle that cost me 6 euro in poland.......

Banned in Ireland..... Now im confused..is it dangerous?

banned? What an idiot could do this?
Tribulus is a 100% safe. All respected companies have tribulus or tribulus based products - NOW, Optimum, Universal...etc. The problem is that, most of them do not show the origin of the tribulus and those who do it and claim it is bulgarian, unless they show a document of it's origin can't be 100% sure.
