The latest research and researchers in Australia have just published medical data showing a positive and beneficial influence of human growth hormone (HGH) therapy on sprint capabilities and abilities in athletes. The effect was even more pronounced when androgenic hormone or testosterone was co-administered.

Athletes using HGH experienced a 0.4-second enhancement in a 10-second sprint.

“This improvement could turn the last place finished in the Olympic finals into a gold medal winner,” Ken Ho, MD, head of the department of endocrinology at St. Vincent’s Hospital in Sydney, said in a press release.

These information make a case for Growth hormone being a banned substance, despite the fact that evidence of its overall performance-increasing impact has been poor until now, in accordance to researchers.

The study included 96 recreationally skilled sports athletes, which include sixty three men (mean age, 28 years). Dr. Ho and colleagues arbitrarily designated athletes to a placebo, Gh 2 mg per day, testosterone 250 mg per week for men only, or combined Growth hormone and testosterone.

Spring capability significant upgraded for men and women who obtained human GH (combined improvement, 0.71 kJ; 95% CI, 0.1-1.3), for a relative increase of 3.9%.

Males assigned to Gh and testosterone encountered greater advancements in sprint capacity (0.71 kJ; 95% CI, 0.5-3.0), equal to a relative increase of 8.3%.

In a 6-week follow-up, spring capacity improvements were not maintained, according to the scientists.

Combination treatment in males was additionally associated with considerably decreased fat mass and increased lean body mass through an improvement in extracellular water and body cell mass.

The researchers observed hardly any substantial modifications in other overall performance procedures such as endurance and stamina, strength and power.

Athletes in all treatment organizations reported swelling, joint/muscle pain, paresthesias and acne breakouts; however, adverse consequences were more frequent in those assigned to Human growth hormone, particularly joint pain.

“In our study, we used doses of GH on the low end of what is believed to be abused in sports,” Ho said. “For that reason, we think that the real effects of GH could be far greater than what is reported in our study. Equally, the side effects could be much more serious, as well.”


The analysts suggested long term investigation to address aerobic performance, energy and ability responses to Gh treatment at increased amounts for extended periods and an assessment of the biochemical components that trigger growth hormone growth of anaerobic capacity.
