Been on it for about a week and a half now. I'm up to 20mg a day on week 2. So far no side effects. Not tired got my bp checked Systolic Normal/High but diastolic is optimal. Both readings are the norm for me. I havent got anything else checked yet. But so Far so Good. Getting Mad pumps from this suff strengh and endurance is up too. Anyone have any suggestions/input/2 cents?
