"Tribulus is effective in only about 40% of the people who try it, and the effect is mild at best. It's also been shown that Tribulus does next to nothing in men with suppressed HPTA's such as steroid users, older men, or men with naturally low testosterone"

The aphrodisiac herb Tribulus terrestris does not influence the androgen production in young men.

OBJECTIVE: The aim of the current study is to investigate the influence of Tribulus terrestris extract on androgen metabolism in young males. DESIGN AND METHODS: Twenty-one healthy young 20-36 years old men with body weight ranging from 60 to 125 kg were randomly separated into three groups-two experimental (each n=7) and a control (placebo) one (n=7). The experimental groups were named TT1 and TT2 and the subjects were assigned to consume 20 and 10 mg/kg body weight per day of Tribulus terrestris extract, respectively, separated into three daily intakes for 4 weeks. Testosterone, androstenedione and luteinizing hormone levels in the serum were measured 24 h before supplementation (clear probe), and at 24, 72, 240, 408 and 576 h from the beginning of the supplementation. RESULTS: There was no significant difference between Tribulus terrestris supplemented groups and controls in the serum testosterone (TT1 (mean+/-S.D.: 15.75+/-1.75 nmol/l); TT2 (mean+/-S.D.: 16.32+/-1.57 nmol/l); controls (mean+/-S.D.: 17.74+/-1.09 nmol/l) (p>0.05)), androstenedione (TT1 (mean+/-S.D.: 1.927+/-0.126 ng/ml); TT2 (mean+/-S.D.: 2.026+/-0.256 ng/ml); controls (mean+/-S.D.: 1.952+/-0.236 ng/ml) (p>0.05)) or luteinizing hormone (TT1 (mean+/-S.D.: 4.662+/-0.274U/l); TT2 (mean+/-S.D.: 4.103+/-0.869U/l); controls (mean+/-S.D.: 4.170+/-0.406U/l) (p>0.05)) levels. All results were within the normal range. The findings in the current study anti____te that Tribulus terrestris steroid saponins possess neither direct nor indirect androgen-increasing properties. The study will be extended in the clarifying the probable mode of action of Tribulus terrestris steroid saponins.

Steroidal saponins from Dioscorea panthaica and their cytotoxic activity.

Dong M, Feng XZ, Wang BX, Ikejima T, Wu LJ.

Department of Cell Biology, Neurobiology, and Anatomy, University of Cincinnati, Ohio, USA.

A new steroidal saponin, dioscoreside E (1), and a known compound, protodioscin (2), were isolated from an ethanol extract of the rhizomes of Dioscorea panthaica. The structure of 1 was established as 3-O-[bis-alpha-L-rhamnopyranosyl-(1 --> 2 and 1 --> 4)-beta-D-glucopyranosyl]-26-O-beta-D-glucopyranosyl-20(R)-methoxy-25(R)-furosta-5,22(23)-diene-3beta,26-diol, on the basis of spectral and chemical evidence. Compounds 1 and 2 showed cytotoxic activity against a panel of tumor cell lines

its quite likely that any aphodesiac properties of tribulus are due to phytoestrogenic chemicals.

i am not sayin ur wrong but can u prove this i am reallty curious.

Yup, I sure can. I took it ED for 6 weeks @ 1500mg and went to get a blood test the next day after my last dose and my total testosterone was 66 points lower than the pre-test done before supplementation.

really interesting is the same for all tribu products. i've taken vitrex by nutrex after an m1t and did noticed i helped a little nothing like clomid or hcg. i started getting more acne on my face

[roccodart440]

Imiust add that I id feel and see some results for about the fis=rt 2 eweeks but the end result was sad. A worse...me.

[Deep-Squats]

Agreed. I also tried tribulus about 6 months ago for 3 months. My T levels went down 10% post tribulus. I posted a thread when this happened. Weird. Oh well at least now I know.

triubulus can also decrease natural production after a continueos use.750mg increases test levels by about 44%.i dont know how long it stays elevated for.but what i do know is that because its a stimulus after a long term of usage it will suppress testosterone levels.It is the herbal form of hcg which you should also have a break from after several weeks to stop dependance on it.
