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 randomized controlled trial.

GH is an important regulator of fat metabolism at rest, but it is not known whether it regulates fat metabolism during exercise.

Metabolic studies, at rest, during and following exhaustive exercise were carried out at baseline and at the end of the 3 months.

Who Took Part

PubMed indexes the participants as adults, middle-aged adults and older adults, both men and women.

Changes in body composition were assessed using dual-energy x-ray absorptiometry scanning and anthropometric measurements.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

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.

Neither the participants nor the staff measuring them knew who was on Exogenous HGH, sermorelin & older GHRPs (why they're passed over), so expectations could not easily colour the readings.

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

The rate of appearance of glycerol (glycerol Ra, an index of lipolysis) and free fatty acids (FFA, FFA Ra) and the rate of disappearance of FFA (FFA Rd) in the plasma were measured using infusions of (2)H(5)-glycerol and 1-(13)C-palmitic acid.

What Was Measured

Topics PubMed links to this paper include Absorptiometry, Photon, Adipose Tissue, Aerobiosis, Body Composition, Body Constitution, Carbon Isotopes and Deuterium.

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).

The publication is from 2003 (The Journal of clinical endocrinology and metabolism), a journal based in United States.

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.
