Thanks all, pulse was down by early evening and slept fine. I had taken 2 pills in the morn yesterday. Just took 1 this morning and about to go lift.
To answer the questions: I am mid-30s, started martial arts about 6 months ago and have been doing mild cardio in addition. Adding moderate weights this week, am very heavy but doctor says I have a healthy heart, pressure, chol etc. Other than that, I am a computer programmer so I am primarily sedentary during the day.
Thought this stuff could give me a boost safely,
Thanks for the advice, it did put my mind at ease.
