I work a crazy scedule, sometimes nites sometimes days. allways 12 hours, I have frequent vacations to enjoy the outdoors. I am looking for a supplement that can be taken on a scedule like mine, most supplements I have seen are to be taken on a set schedule, I need something different. Not looking to hulk up just improve overall fitness and awareness. I have moderately hbp, which i want to get rid of through fitness. I am 37 years old, 230 lb, 6'3", not over weight, just corn fed as we call it in Texas. Please offer any advise that will help me in my quest.
