I just lowered the tone with you because you always try to say the same thing about what I say. Copy those scientific words and put on Google and You will find out the whole scientific study showing How panax ginseng is estrogenic.
Regarding tribulus acting on Androgen Receptors
Effect of Tribulus terrestris on nicotinamide adenine dinucleotide phosphate-diaphorase activity and androgen receptors in rat brain. - PubMed - NCBI (Study in rats. There are studies in humans But I imagine you don't read portugueses nor italian so I would not waste my time)
Dietary supplement
T. terrestris is now being promoted as a booster for the purpose of increasing sex drive. Its use for this purpose originated in Eastern Europe in the 1970s. It was popularized in America by 1970s strongman Jeffrey Petermann. Independent studies [5] have suggested that Tribulus terrestris extract slightly increases hormone levels, though leaving them in the normal range.
The extract is claimed to increase the body's natural testosterone levels and thereby improve male sexual performance and help build muscle. T. terrestris has consistently failed to increase testosterone levels in controlled studies.[6][7][8] It has also failed to demonstrate strength-enhancing properties.[9] However, many supplement brands have sold products that combine various herbs with T. terrestris, with debatable effects.
Tribulus has been shown to enhance sexual behaviour in an animal model.[10] It appears to do so by stimulating androgen receptors in the brain.
Some body builders use T. terrestris as post cycle therapy or "PCT". After they have completed an anabolic-steroid cycle, they use it under the assumption that it will restore the body's natural testosterone levels.
