Larry says that these injections, in conjunction with human growth hormone, are one of the most important elements in his longevity program. In fact, Larry was an early adopter of HGH injections, though he does not use it continuously. He'll typically use it for a month or two to coincide with his marathon-training periods, then take one month off. With 53 marathons and two ultramarathons under his belt, Larry has noticed a big difference in his performance since beginning his regime. That was about an hour faster than the first one I ran 30 years earlier.
Antioxidants play a critical role as well.
Larry loads up on CoQ10, vitamin E and grape seed extract, which he has found especially helpful in preventing the soreness and stiffness that often follow a strenuous run. In fact, he now takes it at regular intervals during marathons. We find that we feel so good after one race that we can run another marathon the next day. Larry originally took up long distance running to keep weight off, then became hooked on it as a lifestyle. One of his most rewarding workouts is a grueling series of sprints, which helps with both balance and reflex.
