Temporal patterns of lipolytic regulators in adipose tissue after acute growth hormone exposure in human subjects: A randomized controlled 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.

Growth hormone (GH) stimulates lipolysis, but the underlying mechanisms remain incompletely understood.

The researchers examined the effect of GH on the expression of lipolytic regulators in adipose tissue (AT).

Who Took Part

By PubMed's age tags, the people studied were young adults and adults, men only.

In a randomized, placebo-controlled, cross-over study, nine men were examined after injection of 1) a GH bolus and 2) a GH-receptor antagonist (pegvisomant) followed by four AT biopsies.

In a second study, eight men were examined in a 2 × 2 factorial design including GH infusion and 36-h fasting with AT biopsies obtained during a basal period and a hyperinsulinemic-euglycemic clamp.

How the Study Was Run

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

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.

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.

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

In addition, mechanistic experiments in mouse models and 3T3-L1 adipocytes were performed.
