@walkerfitmuscle: If you're over 50 and dragging through every day, it's probably not your age. It's usually four things nobody wants to hear. Not enough sleep. Not enough protein. No resistance training. And blood sugar bouncing all over the place. Fix those four before you touch a supplement or ask for a prescription. Most guys feel like themselves again within weeks. If you're still gassed after that, then it's time to talk to your doctor. Comment "ENERGY" and I'll send you my Energy Reset Checklist.
