Effect of growth hormone replacement on bone mass in adults with adult onset growth hormone deficiency.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

Previous studies of the effect of GH replacement on bone mass in adults with GH deficiency have produced conflicting results.

Who Took Part

The abstract describes 10 men taking part.

The age groups tagged for this paper are adults and middle-aged adults, both men and women.

Twenty-two adults (10 men, 12 women), aged 41.5 +/- 2.1 years (mean +/- SE, range 23.6-59.5), with adult onset GH deficiency.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

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.

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.

Single-energy quantitative computed tomography was used to measure vertebral trabecular bone mineral density (BMD), single-photon absorptiometry (SPA) was used to measure forearm cortical and integral bone mineral content and BMD and dual-energy X-ray absorptiometry (DXA) was used to measure lumbar spine, femoral neck, trochanteric and Ward's triangle integral BMD.

What Was Measured

The subject headings attached to it are Bone Density, Femur Neck, Forearm, Growth Hormone and Lumbar Vertebrae.

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 10 men.

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.

Its findings take up roughly 6 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 1995 (Clinical endocrinology), a journal based in England.
