tribulus = reduced sexual sides

[mooman80]

just want to publicize tribulus a bit more, since it seems to be working well for me and isn't talked about too much

bout a month ago I was just about to quit propecia after 5 years due to increasingly bad sexual side effects over the last year (libido, weak erection). so i started taking tribulus terrestris three weeks ago. libido has returned, hurray! Now i am pretty sure this is not a placebo effect, as pre-tribulus i was luckily to have had 1 or 2 "happy" dreams per month. so far this week i'm 6/7 and having morning wood , which was rare.

I'm taking 3 capsules of it per day, which amounts to 375 mg of the supposed active chemical saponins. this is in addition to 4000mg of L-Arginine/Ornithine combo per day (for weak erection). caution though, as tribulus supposedly works by increasing testosterone levels, which can be converted to DHT. hopefully the finasteride will prevent this :?

good luck

I tried tribulus a while back, and it helped me the same way. But if it raises T levels, then finasteride may not be able to stop the extra T converting to DHT. And the arginine question was raised a while back, it does help with libido but your body builds up a tolerance to it so a trick dosage or 3 weeks on 1 week off or something along those lines may help with long term usage. Look for the post, its pretty old i think Brian answered it though.

This study suggests tribulus works by increasing NO levels similar to arginine or v****.

INTRODUCTION: The objective of the present study was to investigate the effect of oral treatment of Tribulus terrestris (TT) extract on the isolated corpus cavernosal tissue of New Zealand white (NZW) rabbits and to determine the mechanism by which protodioscin (PTN), a constituent of the TT, exerts its pharmacological effects. MATERIALS AND METHODS: Twenty-four NZW rabbits were randomly assigned to 4 experimental groups of 6 each. Group I served as control. Groups II to IV were treated with the extract at different dose levels, i.e. 2.5 mg/kg, 5 mg/kg and 10 mg/kg body weight, respectively. The TT extract was administered orally, once daily, for a period of 8 weeks. The rabbits were then sacrificed and their penile tissue isolated to evaluate the responses to both contracting and relaxing pharmacological agents and electrical field stimulation (EFS). RESULTS: PTN on its own had no effect on the isolated corpus cavernosal strips. The relaxant responses to EFS, acetylcholine and nitroglycerin in noradrenaline precontracted tissues from treated groups showed an increase in relaxation of a concentration dependent nature compared to that of the tissues from control group. However, the contractile, anti-erectile response of corpus cavernosal tissue to noradrenaline and histamine showed no significant change between the treatment and the control groups. CONCLUSIONS: The relaxant responses to acetylcholine, nitroglycerin and EFS by more than 10%, 24% and 10% respectively compared to their control values and the lack of such effect on the contractile response to noradrenaline and histamine indicate that PTN has a proerectile activity. The enhanced relaxant effect observed is probably due to increase in the release of nitric oxide from the endothelium and nitrergic nerve endings, which may account for its claims as an aphrodisiac. However, further study is needed to clarify the precise mechanism of its action.
