Growth hormone replacement does not improve psychological well-being in adult hypopituitarism: a randomized crossover trial.

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.

Who Took Part

According to the abstract, 20 adults were involved.

The age groups tagged for this paper are adults, middle-aged adults and older adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and crossover 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 adults received a placebo instead of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), giving a reference point.

In the crossover set-up each of the adults took both Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and the comparison in turn, acting as their own control.

What Was Measured

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 20 adults.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1998 (Psychoneuroendocrinology), a journal based in England.
