Warning for Seniors
Growth Hormone Injections


WASHINGTON (UPI) -- As many as 500,000 otherwise healthy seniors are getting injections of synthetic human growth hormone each year.


Some seniors swear the hormone reduces fat, makes them more active and increases libido, but some researchers say this practice, that can cost as much as $10,000 a year, can have serious and potentially deadly side effects, USA Today reported.

FDA Warnings

The U.S. Food and Drug Administration has approved the use of synthetic growth hormone for boys likely to become adults shorter than 5-foot-3 and girls likely to be shorter than 4-foot-11. However, when growth hormone is prescribed for adults, it's considered "on-label," and a doctor can prescribe the hormone for no specific condition except that a doctor feels a patient will benefit.

There's a better way than injections to get the benefits of increasing growth hormone, high-intensity exercise!

Exercise does the trick

Researchers compared growth hormone levels in several ways — resting, after a single 6 second cycle sprint, and after a 30 second cycle sprint. They also measured growth hormone for hours afterwards to see how long HGH stayed in participant’s bodies after exercise. (The time course of the human growth hormone response to a 6s and a 30s cycle ergometer sprint, 2002, Stokes).

Research results

The 6 second sprint method did move HGH some.  But it didn’t come close to the body’s potential to release this powerful hormone. As Ready, Set GO! Synergy Fitness reported, it takes at least 8 seconds of high-intensity to typically reach lactic acid (a mission critical HGH release benchmark).

The 30 second all-out effort sprint experiment increased growth hormone by 530% over resting baseline.  And the 30 second sprint produced a response 450% greater than the lesser intensity sprint. (A summary of this study can be seen at the National Institutes of Health, link below.)

Like earlier research studies, growth hormone stayed elevated for 1.5 to 2 hours after the sprint program.

Why middle-age and senior adults need more
than 30 seconds of an all-out sprint

The Ready Set Go Workout

The Ready Set Go Sprint 8 Workout is a progressive, 8 repetition, build-up sprint program (to help avoid injury). The one 30 second sprint version may be okay for a young, elite athlete who can hold maximal effort. For most of us however, it will take a build-up sprint program to achieve 30 seconds of maximum effort during a workout. In fact, there’s research showing absolute peak effort can only be held for 4 to 6 seconds.

There are additional cardio benefits with the Sprint 8 Workout. The Sprint 8 Workout will keep the heart rate above cardio target heart rate for most of the 20 minute workout, which multi-tasks and accomplishes two workouts (aerobic and anaerobic) in a short amount of time. If time-crunched adults can find a way to squeeze in 20 minutes, they'll get two workouts in one - with this method.

The take home

If you want the wonderful benefits of exercise-induced growth hormone, this workout is the NATURAL choice.

Spread the word. Tell your friends and relatives about these new research discoveries and how they can get the benefits of increasing growth hormone naturally through high-intensity exercise.

Have a great day!
