Strength at any given time is a finite measurable, a substance doesn’t give anyone more than that finite number. Steroids (in the context you’re referring to) allows your muscles to heal faster from workouts. It can make you stronger, faster, over time, with work. Adrenaline activates your sympathetic nervous system (fight or flight), but if you’re in a situation to need strength against a foe, you’ve already started producing it naturally. I understand that people on pcp seem super human, but that effect is mental rather than physical.
