HGH Benefits

HGH Benefits

Before we elaborate on potential HGH benefits, it should be noted that HGH is not approved for anti-aging. Studies involving growth hormone therapy (GH therapy) in older men have shown significant side effects. In addition to these side effects, other major concerns exist with GH therapy in men without growth hormone deficiency. These concerns include the following: 1) the limited scale of studies, and 2) the unknown long-term link between HGH therapy and cancer or other diseases.

While the number of studies involving HGH therapy use in men without growth hormone deficiency is limited, these studies suggest that HGH therapy does produce favorable changes to body composition. These HGH benefits include the following:

  • Increased bone mineral density
  • Decreased fat mass
  • Increased lean body mass

These HGH benefits have no doubt enhanced interest in HGH therapy for aging men. However, these same studies show high rates of adverse side effects. (See HGH Side Effects)


HGH Benefits: Extended Discussion

  • Increased Lean Body Mass – Studies show that both HGH therapy and HGH therapy plus exercise increase lean body mass by an average of approximately 5 lbs. over a 26-week evaluation period.1-14 As expected, HGH therapy plus exercise is superior to GH therapy alone for increasing muscle mass. Of note, the changes to lean body mass brought by HGH therapy do not produce meaningful increases in muscle strength or physical function.
  • Decreased Fat Mass – One of the more interesting HGH benefits is decreased fat mass. Studies show that HGH therapy and HGH therapy plus exercise both decrease fat mass by an average of approximately 5 lbs over a 26-week evaluation period.1-14 As expected, the HGH benefits of HGH therapy plus exercise produces a slightly greater decrease in fat mass than HGH therapy alone. If you combine the increase in muscle with the decrease if fat, study participants generally weighed the same weight at the end of the study. Yet, their overall body composition changed rather dramatically (5 more lbs. of muscle and 5 fewer lbs. of fat).

Fat reductions occur primarily in the abdominal region. Fat in the abdominal region is the type of fat most commonly associated with multiple significant health problems, including cardiovascular disease and diabetes. Consequently, a reduction in abdominal fat can potentially improve multiple health markers as well as overall health.

  • Increased Bone Mineral Density – Although few studies exist evaluating bone mineral density, the few studies that do exist have suggested that HGH therapy may increase bone mineral density.1,3,13,15 However, no evidence exists to show that these increases in bone mineral density decrease fracture risk in humans.
