What This Study Did, in Plain Language

What Was Tested

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

Overnight blood sampling for repeated growth hormone (GH) assays, regarded as the most physiological assessment of GH status, may induce some disturbances in patients' sleep and then in the evaluation of GH secretion.

Who Took Part

The abstract describes 12 volunteers taking part.

By PubMed's age tags, the people studied were children, teenagers and adults, both men and women.

How the Study Was Run

The design is described as double-blind, placebo-controlled, crossover and parallel-group.

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.

A placebo (an inactive look-alike) gave the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) group a baseline to be compared against.

Each person switched between Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and the comparison at some point, usually with a gap in between.

Groups ran in parallel: each of the volunteers stayed in one arm throughout.

What Was Measured

Overnight blood sampling for repeated growth hormone (GH) assays, regarded as the most physiological assessment of GH status, may induce some disturbances in patients' sleep and then in the evaluation of GH secretion.

PubMed files the paper under topics including Circadian Rhythm, Growth Hormone, Hypnotics and Sedatives, Pyridines, Sleep and Zolpidem.

What This Means in Plain Language

The paper is a double-blind, placebo-controlled and crossover study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 12 volunteers.

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 1991 (Hormone research), a journal based in Switzerland.

Our Notes on the Compound

Exogenous HGH, sermorelin & older GHRPs (why they're passed over): Constant levels suppress the body's own GHRH, raise somatostatin and dull pituitary response.
