The effects of growth hormone replacement therapy on overnight metabolic fuels in hypopituitary patients.

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 researchers investigated whether GH replacement corrects the overnight fuel deficiency.

Who Took Part

According to the abstract, 8 women were involved.

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

The researchers measured circulating levels of metabolic fuels: glucose, non-esterified fatty acids (NEFA), glycerol and 3-hydroxybutyrate (3-OHB) and insulin concentrations over 24 h (from 0730 h to 0700 h) in hypopituitary adults before and after GH treatment in a randomized double-blind placebo-controlled trial of 3 months' duration.

How the Study Was Run

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

Random assignment meant chance, not the researchers, decided who got Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and who got the comparison, which limits bias.

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.

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

Topics PubMed links to this paper include 3-Hydroxybutyric Acid, Area Under Curve, Blood Glucose, Fatty Acids, Nonesterified, Glycerol, Human Growth Hormone and Hypopituitarism.

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 8 women.

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 abstract goes on to report its results in about 8 sentences; this page does not restate them, so read the paper for the findings and their limits.

The publication is from 2000 (Clinical endocrinology), a journal based in England.
