Testosterone boosters are a class of herbal or otherwise legal supplements that aim to increase levels of testosterone in the body. This page discusses all compounds either marketed as or investigated for their usage as testosterone boosters or pro-androgenic compounds. For this reason, entries below may not actually boost testosterone. Many of the compounds below do indeed boost testosterone levels in some studies, but others either require hypogonadism or are just aphrodisiacs.
Note on Aromatase Inhibitors
A novel mechanism of increasing testosterone in men is through inhibiting the aromatase enzyme (also known as CYP19A1). This enzyme serves many purposes, one of which is to convert androgens (like testosterone) to estrogens. For more, see: anti-estrogen/aromatase inhibitors.
Inhibiting the enzyme itself can increase testosterone and lower estrogen. Aromatase inhibitors can be useful as single supplements to take in order to switch the body to a more androgenic state.
Increasing testosterone by other means, such as hypothalamic stimulation (see: D-Aspartic Acid and possibly Anacyclus Pyrethrum), can yield more testosterone independent of this enzyme, and the enzyme's activity may be increased to compensate. In this scenario, supplementation with an aromatase inhibitor may be prudent to avoid the increase in estrogen caused by the increase in testosterone. It may not be needed (in the truest sense of the word) with nutraceuticals, but would still be a good idea regardless.
