Found this info about trib on the net. Important to note -
"Be sure to choose an extract standardized for at least 30-45% steroidal saponins (furostanol)."
It is my understanding that tribulus is only effective at high levels of standardization. Thus the best trib is the one which has the highest percentage per mg of the active furostanol.
Tribulus Terrestris
This herb used in Ayurvedic medicine that’s also known as puncture vine, has been shown to boost testosterone levels naturally through a unique mechanism. Basically, it stimulates leutinizing hormone (LH) production from the anterior pituitary gland, which in turn stimulates testosterone production. Some clinical studies have shown that tribulus can enhance LH and free testosterone levels in healthy subjects by 70 and 40 percent, respectively. A Bulgarian study revealed that more than 200 men suffering from impotence—which is often caused by low testosterone levels—showed improved testosterone and LH levels as well as sperm production after the subjects supplemented with a preparation of tribulus terrestris. The research also shows it to be very safe. The LD50, a measure of an ingredient’s lethal toxicity, for tribulus in rats was more than 10 grams per kilogram of bodyweight, which is an incredibly high dose. The active compounds of tribulus terrestris that may be responsible for its anabolic and aphrodisiac properties are the furostanol saponins, including protodioscin. It works at a divided dose of about 750 to 1500 milligrams per day. Great times to take it are first thing in the morning and one hour before a workout.
Supplement Tribulus Terrestris
Description Tribulus (puncture vine) is a vine that has been used as a general tonic (energy) and herbal treatment for impotence, but is found primarily in dietary supplements marketed for increasing testosterone levels in bodybuilders and power athletes.
Claims Increased testosterone production
Increased muscle mass/strength
Theory The idea behind tribulus is that it may increase testosterone levels indirectly by raising blood levels of another hormone, luteinizing hormone (LH). LH is a hormone produced by the pituitary gland and plays a role in regulating natural testosterone production and serum levels.
Scientific Support The active ingredient in tribulus is unknown, but is though to be a component known as furostanol saponins. There has been very little research conducted on the effectiveness of tribulus in elevating testosterone levels – the main claim made by body building products which contain the herb. In some cultures, the tribulus terrestris plant has been used as a "tonic" to in crease energy levels and treat sexual dysfunction (usually in males). In animals, tribulus may stimulate "mounting" behavior. Some European studies suggest that tribulus extract can increase testosterone levels 30-50% above baseline levels – but still well within the normal range. Unfortunately, however, these same studies also suggest a similar increase in estradiol levels – not exactly what the hardcore muscle builders should be interested in boosting
If tribulus extract does indeed elevate testosterone levels somewhat, but keeps them within normal ranges, it may be an effective supplement for individuals with reduced testosterone levels such as athletes at risk for overtraining syndrome and in those individuals on a prolonged low-calorie diet. It will not, however, cause you to start sprouting muscles from all parts of your body, as many body building mags would have you believe.
In one of the few well-controlled studies to examine the effects of tribulus terrestris on body composition and exercise performance looked at 15 resistance-trained males. Subjects received either a placebo or a large dose of tribulus (1.5mg per pound of body weight per day for 2 months). Results showed no changes in body weight, percentage fat, total muscle mass or muscle strength related to tribulus supplementation.
Safety Although no significant side effects should be expected at doses of tribulus contained in commercial dietary supplements, animal studies have suggested the possibility of locomotor (muscle coordination) disturbances following ingestion of tribulus in high quantities. In sheep consuming tribulus plant for several months, neurological disease was characterized by an irreversible, asymmetrical, weakness of the hindlimbs.
Value Products containing tribulus are typically marketed to bodybuilders and athletes concerned with increasing muscle mass and strength. Although such products are typically combinations of ingredients which include tribulus, rather than tribulus alone, the scientific evidence for product effectiveness is typically lacking. At this time, Supplement Watch does not view tribulus extract (on its own) as a valuable dietary supplement for muscle building. As a support ingredient contained in a wider supplement blend, tribulus may provide some benefits to those individuals interested in maintaining testosterone levels in the normal range (overtrained athletes and dieters).
Dosage A typical dosage of 250-1500 mg of tribulus per day is fairly common. Be sure to choose an extract standardized for at least 30-45% steroidal saponins (furostanol).

That study is a bit of a joke because depending on the delivery system of the supplement you need to get at least 1000mgs for a very efficient product to up to 3500mgs for a not so efficient product. You have to get enough of it for it to take effect because the main compound protodioscin is in such small quantities that it's necessary to get enough so that it works like it's supposed to.
Now tell me, how are you supposed to get any positive benefits from it when you're not even tkaing an effective dosage to see results. At 1.5mgs per pound of bodyweight, that's only 300mgs a day. That is nothing. No wonder no positive benefits were shown lmao.
Makes you wonder how smart these supposed scientists really are....

Yes, you are right about the active compound being usually found in small quantities. This is why recommendations are varied. Dosage is dependent on the active saponins. The active compounds of tribulus terrestris that may be responsible for its anabolic and aphrodisiac properties are the furostanol saponins, including protodioscin. Recently, two new saponins have been isolated from tribulus terrestris: Terrestrinins A and B.
I maintain my point about the high concentration of active saponins being very important: Different samples of tribulus have been analyzed, with significant differences in the composition of saponins observed depending on the origin and plant part used. One analysis of products showed considerable variations of 0.17 to 6.5 % in protodioscin content.
For all intent and purposes, this is why I have
according to Rehan Jalili, the head of the supplement research foundation trib works at a divided dose of about 750 to 1500 milligrams per day. "Great times to take it are first thing in the morning and one hour before a workout"
However, because of variations in active saponins, these reccomendations are sketchy at best, and probably apply only to a trib, which has the required high concentration of saponins.
For anyone thats interested, here are some abstracts purtaining to trib:
Effect of Tribulus terrestris on nicotinamide adenine dinucleotide phosphate-diaphorase activity and androgen receptors in rat brain.
J Ethnopharmacol. 2005 Jan 4;96(1-2):127-32.
Tribulus terrestris L. (Zygophyllaceae) have been used as an aphrodisiac both in the Indian and Chinese traditional systems of medicine. Administration of Tribulus terrestris extract increased sexual behaviour and intracavernous pressure both in normal and castrated rats and these effects were probably due to the androgen increasing property of tribulus. The objective of the present study is to evaluate the effect of tribulus on nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) activity and androgen receptor (AR) immunoreactivity in rat brain. Twenty-four adult male Sprague-Dawley rats were divided into two groups of twelve each. Group I was treated with distilled water and Group II was treated with tribulus terrestris at the dose of 5mg/kg body weight orally, once daily for 8 weeks. Following treatment transcardiac perfusion was done with Ringer lactate, 4% paraformaldehyde and 30% sucrose. The brain tissue was removed and sections of the paraventricular (PVN) area of hypothalamus were taken for NADPH-d and AR immunostaining. There was an increase in both NADPH-d (67%) and AR immunoreactivity (58%) in tribulus terrestris treated group and these results were statistically significant compared to the control. Chronic treatment of tribulus terrestris in rats increases the NADPH-d positive neurons and AR immunoreactivity in the PVN region. Androgens are known to increase both AR and NADPH-d positive neurons either directly or by its conversion to oestrogen. The mechanism for the observed increase in AR and NADPH-d positive neurons in the present study is probably due to the androgen increasing property of tribulus terrestris. The findings from the present study add further support to the aphrodisiac claims of tribulus terrestris.

Study of antihypertensive mechanism of Tribulus terestris in 2K1C hypertensive rats: role of tissue ACE activity.
Life Sci. 2003 Oct 24;73(23):2963-71.
Tribulus terrestris is a natural herb used for treating many diseases including hypertension. According to previous reports, aqueous extract of tribulus fruits may have some antihypertensive effect with an unknown mechanism. The present study investigated the antihypertensive mechanism of tribulus in 2K1C hypertensive rats by measurement of circulatory and local ACE activity in aorta, heart, kidney and lung. Four groups of rats were selected; control, sham, operated or hypertensive and tribulus treated hypertensive group. Hypertension was induced using silver clip on renal artery by surgery. Four weeks after surgery, a single daily dose of 10 mg/kg of lyophilized aqueous extract of tribulus fruit were given orally to rats for four weeks. The systolic blood pressure (SBP) was significantly increased in 2K1C rats compared to control rats. The SBP of tribulus fed hypertensive rats was significantly decreased compared to hypertensive rats. The ACE activity in all tissues of 2K1C rats including: aorta, heart, kidney, lung as well as serum were significantly increased compared to normal rats. The ACE activity in all tissues of tribulus fed hypertensive rats was significantly lower than that of hypertensive rats, which was more pronounced in kidney. These results indicated that there is a negative correlation between consumption of tribulus terrestris and ACE activity in serum and different tissues in 2K1C rats. tribulus terrestris tribulus tribulus side effects tribulus terrestis.

Experimental Tribulus terrestris poisoning in sheep: clinical, laboratory and pathological findings.
Vet Res Commun. 2003 Jan;27(1):53-62.
Eleven native sheep, 1-2 years old, of both sexes were randomly divided into two groups, 6 sheep being allocated to the experimental group and 5 serving as controls. The sheep in the experimental group were fed 80% Tribulus terrestris and 20% alfalfa hay and wheat straw, while the control sheep were given a mixture of 40% alfalfa hay and 60% wheat straw. Clinical signs of hepatogenous photosensitivity were observed from day 11, including reddening and crust formation on the muzzle, nose, ears and eyelids, depression, weight loss, icterus, conjunctivitis, and yellow discoloration of the urine. Laboratory findings on weekly samples indicated significant differences in white blood cell count, total plasma protein and fibrinogen, total and direct bilirubin, blood urea nitrogen and creatinine concentrations. There were no significant differences in the packed cell volume, in the neutrophil, lymphocyte or eosinophil counts, or in the serum calcium, phosphorus, potassium, sodium or chloride concentrations. At necropsy of the animals consuming tribulus terrestris, there were various degrees of generalized icterus and the livers were swollen and discolored by bile pigment. Histopathological examination revealed varying amounts of crystalloid material in the bile ducts and renal tubules, hepatocellular degeneration, biliary fibrosis and proliferation, renal tubular necrosis and focal necrosis of cardiac muscle. bulgarian tribulus tribulus and terrestris and linn tribulus terestris canada terrestris tribulus extract tribulus extreme fuel tribulus product tribulus terristris tribulus.
Aphrodisiac properties of Tribulus Terrestris extract (Protodioscin) in normal and castrated rats.
Life Sci. 2002 Aug 9;71(12):1385-96.
Tribulus terrestris has long been used in the traditional Chinese and Indian systems of medicine for the treatment of various ailments and is popularly claimed to improve sexual functions in man. Sexual behavior and intracavernous pressure (ICP) were studied in both normal and castrated rats to further understand the role of Tribulus terrestris containing protodioscin (PTN) as an aphrodisiac. Adult Sprague-Dawley rats were divided into five groups of 8 each that included distilled water treated (normal and castrated), testosterone treated (normal and castrated, 10 mg/kg body weight, subcutaneously, bi-weekly) and Tribulus terrestris treated (castrated, 5 mg/kg body weight, orally once daily). Decreases in body weight, prostate weight and ICP were observed among the castrated groups of rats compared to the intact group. There was an overall reduction in the sexual behavior parameters in the castrated groups of rats as reflected by decrease in mount and intromission frequencies (MF and IF) and increase in mount, intromission, ejaculation latencies (ML, IL, EL) as well as post-ejaculatory interval (PEI). Compared to the castrated control, treatment of castrated rats (with either testosterone or Tribulus terrestris extract) showed increase in prostate weight and ICP that were statistically significant. There was also a mild to moderate improvement of the sexual behavior parameters as evidenced by increase in MF and IF; decrease in ML, IL and PEI. It is concluded that Tribulus terrestris extract appears to possess aphrodisiac activity probably due to androgen increasing property of Tribulus terrestris (observed in our earlier study on primates).

The effects of Tribulus terrestris on body composition and exercise performance in resistance-trained males.
Int J Sport Nutr Exerc Metab. 2000 Jun;10(2):208-15. tribulus terrestris extract
The purpose of this study was to determine the effects of the herbal preparation Tribulus terrestris (tribulus) on body composition and exercise performance in resistance-trained males. Fifteen subjects were randomly assigned to a placebo or tribulus (3.21 mg per kg body weight daily) group. Body weight, body composition, maximal strength, dietary intake, and mood states were determined before and after an 8-week exercise (periodized resistance training) and supplementation period. There were no changes in body weight, percentage fat, total body water, dietary intake, or mood states in either group. Muscle endurance (determined by the maximal number of repetitions at 100-200% of body weight) increased for the bench and leg press exercises in the placebo group (p <.05; bench press +/-28.4%, leg press +/-28.6%), while the tribulus terrestris group experienced an increase in leg press strength only . Supplementation with tribulus does not enhance body composition or exercise performance in resistance-trained males. tribulus research, tribulus terrestris.

None of them use enough total tribulus.
From my experience, 2500 to a maximum of 4000mgs a day is best to achieve optimal results, at least from what I've used. I've gotten decent results from as little as 1500mgs a day, but definitely feel that amount is suboptimal. Despite these studies which all use too little tribulus, again making me question just how intelligent these scientists are, my own personal experience shows that a fairly high amount is needed to get optimal results and that it should be cycled either 5 days on, 2 off, or up 8 weeks on, and 2-4 weeks off.
Tribestan may be the strongest tribulus supplement on the market if all their advertising and research isn't just bulloney.
I would guess Biotest Tribex and Nutrex Vitrix being a close second as far as potency is concerned.
I am basing my amounts of tribulus used off cheaper products, or less potent I should say like Optimum Nutrition and MRM brands which are supposed to contain 40-45% saponins.
I am sure Tribestan, Tribex and Vitrix are all significantly more potent and do not require as many mgs to get an optimal effect due to the quality of the Tribulus used and delivery system.

I just got Ultimate Nutritions "Bulgarian tribulus" it was only like 14.95 online and it has 45% steroidal saponins, one of the highest ive seen for the cheap cost. Been taking it for a couple of weeks and is way stronger than the 25% im used to.
