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.

The aim was to compare the impact of raloxifene and tamoxifen on GH-IGF-I and gonadal axes in healthy men.

Why It Was Studied

In men, the stimulation of GH and inhibition of LH secretion by testosterone requires aromatization to estradiol.

Tamoxifen, a selective estrogen receptor modulator (SERM), possesses central estrogen antagonistic effect but peripheral hepatic agonist effect, lowering IGF-I.

Who Took Part

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

How the Study Was Run

The design is described as randomized, open-label and crossover.

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.

Being open-label, the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study did not mask who received what.

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.

The researchers conducted a randomized, open-label crossover study.

What Was Measured

In men, the stimulation of GH and inhibition of LH secretion by testosterone requires aromatization to estradiol.

PubMed files the paper under topics including Androgens, Arginine, Follicle Stimulating Hormone, Growth Hormone, Insulin-Like Growth Factor I, Luteinizing Hormone and Raloxifene Hydrochloride.

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.
