Pre-workout contains Caffeine.
Caffeine increases cortisol and epinephrine levels both at rest and during periods of stress. Although cortisol levels will diminish over time, they stay elevated above baseline all day, even if you take it in the morning.
Caffeine enhances the stress response in both men and women.
Exercise that is of short duration and moderate intensity may not activate a cortisol response if glucose levels remain normal. long duration and intense exercise will increase cortisol output to high levels as a function of metabolic demands on fuel homeostasis.
