"Every night when you sleep, your pituitary gland, a kidney-bean-size gland at the base of your brain, goes to work, squirting out HGH, a polypeptide consisting of 191 amino acids.
HGH flows into your bloodstream and binds to specific cell-surface receptors found throughout your body, including your brain, where those receptors are especially dense in the regions responsible for learning and memory."
(...)
It also binds to fat cells, causing them to release part of their cargo, and stimulates your liver to produce a powerful hormone called insulin-like growth factor 1 (IGF-1), which promotes the growth of bone, cartilage, and muscle.
HGH surges during childhood and adolescence, but by the time you’re 40, you’re producing only about half as much as you were at 20.
Still, even that small amount is critical for body maintenance.
The FDA approved the use of recombinant HGH in 1985 for one thing: extreme deficiency, mostly among the 15,000 children at risk of being unusually short. It was later cleared for HIV/AIDS patients who suffer from muscle wasting, and for people with a condition known as short bowel syndrome."

"“The problem is that growth hormone is almost always used in conjunction with anabolic steroids, and anabolic steroids clearly do work.” So it’s hard to know what portion of the muscle gain, if any, comes from growth hormone."

VERDICT: No to muscle gains, yes to fat loss; but it is expensive

"Crank Up Your Cardio
Nothing makes HGH levels rise like cardio training, says Arthur Weltman, Ph.D., chair of kinesiology at the University of Virginia. But intensity, not duration, is the key to a big “pulse” of growth hormone, he says.
Whether you’re into cycling, biking, or running, your goal should be 45 minutes at a pace you consider difficult, Weltman says. Try to fit in at least two high-intensity cardio workouts a week."

"Grab Heavier Weights
Intensity is your goal with resistance training too, says Weltman. Circuit training—moving from one exercise to another without giving your body a break—is a great way to pump up HGH at the gym.
Weltman suggests using weights that allow you to reach failure at 8 reps. That corresponds to roughly 75 percent of your 1-rep max and it’s a good target to ensure that your intensity is high but not dangerous, he says. Aim for two sessions a week.
