Effect of modafinil on plasma melatonin, cortisol and growth hormone rhythms, rectal temperature and performance in healthy subjects during a 36 h sleep deprivation.

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.

Modafinil is an alerting substance which has been used successfully to treat narcolepsy.

Nothing is known about its effect on hormone secretions.

Who Took Part

PubMed indexes the participants as adults, men only.

How the Study Was Run

In design terms this was 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.

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.

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.

What Was Measured

The subject headings attached to it are Benzhydryl Compounds, Body Temperature, Central Nervous System Stimulants, Health Status, Human Growth Hormone, Hydrocortisone and Melatonin.

What This Means in Plain Language
