T. terrestris is now being promoted as a booster for the purpose of increasing sex drive. Its use for this purpose originated from a Bulgarian study conducted in the 1970s, which found effects on free testosterone and lutenizing hormone in men belonging to infertile couples. A research review conducted in 2000 stated that the lack of data outside of this study prevents generalizing to healthy individuals.
The extract is claimed to increase the body's natural testosterone levels and thereby improve male sexual performance and help build muscle. Its muscle-building potential was popularised by American IFBB bodybuilding champion Jeffrey Petermann in the early 1970s. T. terrestris has consistently failed to increase testosterone levels in controlled studies.It has also failed to demonstrate strength-enhancing properties.However, many supplement brands claim effects of products that combine various herbs with T. terrestris.

Tribulus has been shown to enhance sexual behaviour in an animal model.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.
