Caffeine has been extensively studied for its ergogenic effects, especially in the context of exercise performance. Research suggests that doses of caffeine up to 6-9 milligrams per kilogram of body weight can enhance athletic performance. Studies have found that caffeine can improve endurance, increase alertness, and reduce the perception of effort, making it a popular supplement among athletes.

The choice indicating 9 milligrams per kilogram is supported by various scientific studies, which establish this dosage as being effective in improving performance without significant adverse effects for most individuals. In many cases, the higher end of this range (around 9 mg/kg) has been shown to provide the maximum benefit concerning performance enhancement. Therefore, this dosage is well within the accepted parameters for gaining performance advantages while remaining below thresholds that could lead to excessive side effects or negative health outcomes.

Lower dosages such as 5 mg/kg may still offer benefits but tend to be less potent than the 9 mg/kg dosage in enhancing performance results in competitive scenarios. Higher dosages, such as 11 mg/kg, while sometimes mentioned in literature, surpass typical safety recommendations and are less commonly endorsed due to the heightened risk of side effects.
