Before revision: Microdosing, or micro-dosing, is a technique for studying the behaviour of drugs in humans through the administration of doses so low (" sub-therapeutic ") they are unlikely to produce whole-body effects , but high enough to allow the cellular response to be studied .
After revision: Microdosing, or micro-dosing, involves the administration of sub-therapeutic doses of drugs to study their effects in humans, aiming to gather preliminary data on safety, pharmacokinetics, and potential therapeutic benefits without producing significant physiological effects .
