Hmm, there is so many things. You only get 1 shot at the age you at and only 1 shot at this life, see how fit you can get yourself. I have a friend who went from couch potato to a comrades runner in the space of two years. If running isn't you thing, swim, surf, cycle, skate, whatever, just try see how far you can take it on a health route. I went from a bulky bodybuilder to 93.4 this morning, from only being able to walk with effort to burning 1150 calories in an hour 30 surf. I also average 12k steps a day. Be mindful of everything you put in your body, learn to delay gratification, distance yourself from negative energy as stress hormones effect your blood pressure, visualize what that you new looks like, and in 6 months reevaluate your health and I can assure you will be surprised where you at. You can't keep doing the same thing and expect a different result, no pill or injection is going to be a solution, try a different approach, the intense training will boost your endorphins and you going to see much color in your life. That's just a couple things you can do, a pill only sends signals, your body is what cures or destroys itself.
