Higher levels of testosterone, they found, made the students both more reluctant to give to others and more demanding that others give to them. Here’s how the study was conducted: On varying days, the researchers had 25 male students apply a gel containing placebo; testosterone gel that roughly doubled the level of the hormone in their blood; and a third cream that pushed their testosterone levels even higher.
