Never had any sides previously. None. Lucky enough, I guess it's due genetics and always following strict guideline. Just took my BP (check it twice a day during cycles) and my ready was 113/50 with a Resting heart rate of 58. Anything to worry about? I've never even had to deal with high BP let alone low BP. Oh and on my 3rd week of a 5 week cycle. 30mg M-sten/ 30mg DMZ. 5-11 250 11% BF. do cardio 3 times a week with one day being a 5 mile run and another day being 1 mile as fast as possible. Usually around 6:00. Third day is just walking/stairclimber etc.
