A brand new study published in the current issue of the Annals of Internal Medicine claims that use of hgh injections has been shown to increase the 100 meter sprint speed of athletes by 3.9%. Now we must caution that these were recreational athletes not fully trained competitive athletes.

Still the results are interesting. Most previous studies showed no proof that growth hormone increased athletic performance.

The group of athletes was only 96 in number so this is still a fairly small sampling with only about 15 males with an average age of 27.9 years getting the hgh shots. There was an equal sized group that received injections of both hgh and testosterone. The combined group had an increase of 8.9% showing that the testosterone – human growth hormone combination was the way to go.

The dosage of injectable hgh was 2 mg per day and the dosage of testosterone was 250 mg per week. The testing period was eight weeks.

The growth hormone also decreased fat mass and increased lean body mass. However, the lean mass increase was do to an increase in cellular water not increased muscle mass. So, once again, a study fails to show that hgh increases muscle mass or strength.

An additional finding was that after six weeks the gains disappeared.

The study was funded by the World Anti-Doping Agency that has a stake in there being a positive result.

It will be interesting to follow the public spin on this report. The scam hgh spray pushers will probably try to use selective quotes to push their crap.

Better than dead doctor endorsements.
