Steep time

 * Recommended steep time depends on the kind of tea, and probably on whether it is bag tea or loose leaf tea.
 * Black tea:
 * 2-3 min per lifehacker.com
 * 3-5 min per artoftea.com
 * 3-5 min per packaging of one of the bag teas that I have
 * Thus, largely hearsay
 * Impact of an extended steep time on composition and psychoactive effect:
 * Undetermined.
