Cognitive changes during growth hormone replacement in adult men.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

The present study evaluates the effects of 2 years of growth hormone (GH) replacement therapy on psychological well-being and cognitive performance in adults with childhood-onset growth hormone deficiency (CO-GHD).

Psychological assessments were made every 6 months.

Who Took Part

According to the abstract, 48 men were involved.

By PubMed's age tags, the people studied were adults, men only.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

Because people in this Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The comparison arm used a placebo, so changes seen with Exogenous HGH, sermorelin & older GHRPs (why they're passed over) could be set against what happens without it.

What Was Measured

The present study evaluates the effects of 2 years of growth hormone (GH) replacement therapy on psychological well-being and cognitive performance in adults with childhood-onset growth hormone deficiency (CO-GHD).

Psychological assessments were made every 6 months.
