Serum leptin concentrations during short-term administration of growth hormone and triiodothyronine in healthy adults: a randomised, double-blind placebo-controlled study.

What Was Tested

The paper reports a study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), published as a randomized controlled trial.

The regulation of adipose tissue mass and energy expenditure is currently subject to intensive research, which primarily relates to the discovery of leptin.

Leptin is a peptide, which is the product of the obese (ob) gene expressed in adipose tissue of several species icluding humans.

Who Took Part

The age groups tagged for this paper are adults, men only.

How the Study Was Run

In design terms this was a randomized, double-blind 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.

As a double-blind Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study, the assignments were hidden from both participants and investigators until the end.

Some participants received a placebo instead of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), giving a reference point.

What Was Measured
