So I've had flu-like symptoms the last couple of days, and today I took 600mg of caffeine at 10am in one hit. I also took 3 pills of l-theanine, although an hour or so later when I felt a bit stressed.
I then measured my heart rate which was at 53, usually its around 65. I definitely had a stress response to this caffeine but a lower heart rate?!
