Exercise timing around the stimulant peak. Before the dose or after?

There is no official protocol that exercise must sit before the dose or after the stimulant peak. Stimulants can raise heart rate and blood pressure slightly, which CADDRA discusses in cardiac safety material and which product monographs also list. People with chest pain, fainting, unusual shortness of breath, or a relevant cardiac history need clinical review rather than a gym-timing tweak. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.

Lunch workouts were when I felt the most wired on my long-acting tablet, which I hated. I switched to evenings for a while and then slept worse. I told the clinician about palpitations once and they asked about caffeine too. I did not skip the morning dose for the gym. Just my calendar and a sweaty watch, not advice.

I used to run before the capsule because a thread said the peak would wreck my heart rate. The run was fine. The science in my head was not. I still get a higher pulse on gym days and I mention it if it feels weird. I did not move the dose to match spin class. Only my lunch-hour panic, not a peak protocol.
