I take Vyvanse, so not directly the same. In fact I'm not sure if it and Adderal have the exact same effects on BP since they work differently. I'm definitely considered obese at 6'4" and 280lbs, but there's been literally no movement of my BP up or down since I've been on it. To agree with your point though: 1. Every physical I've ever had has had my vitals in good ranges (minus the weight) 2. I get strenuous physical excercise at least 4x/wk so I'm a spry tub of love I was worried about any possible issues with BP/HR during lifting sessions if I took it before workouts in the morning so I avoided it for a while until my doc reassured it should be fine. As with anything if I felt off, just back down the activity and don't do it tomorrow. I'd say if anything it allows me to run longer on the treadmill or elliptical because I don't get so god damn bored and ready to do something else.

The difference in the brain for Adderall v. Vyvanse comes down to the concentration of which enantiomoers are (how much of which mirror image of amphetamine there is). It's all amphetamine, it all affects the same receptors. The real difference comes down to how long it stays available. Vyvanse sticks around in the blood longer than "plain" amphetamine, but amphetamine crosses into the brain much faster. Both of those are because the liver has to first cleave off the extra molecule tacked onto the amphetamine that makes it Vyvanse. That can only happen so fast, and until it does it's too big to cross the blood/brain barrier or get otherwise disposed of.
