Evidence for sleep

Each row is an outcome related to sleep from a published study, strongest design first. Animal and cell results are labelled and are not human results. User reports are not counted as evidence here.

HGH for sleep: outcomes in published studies
OutcomeResultStudy typeSource
Sleep architectureSleep period time and the intensity of slow-wave sleep were lower after rhGH than after placebo in GH-deficient adults (479 vs 431 min; 559 vs 794 uV2).Human RCTn = 14European journal of endocrinology 2013, PMID 23447518
Night and daytime sleepGH replacement did not affect night sleep or daytime sleep propensity in GH-deficient adults.Human RCTPsychoneuroendocrinology 2005, PMID 15358440
Sleep (well-being scale)The Nottingham Health Profile improved (energy, emotions, sleep), but a similar change also occurred on placebo.Human RCTn = 148Clinical endocrinology 1997, PMID 9404448

PubMed records for HGH and sleep: 153 human, 6 animal (search counts, not studies we reviewed). Grades follow our evidence scale.

How strong is it?

Strongest evidence:Human RCT evidence, 4 of 4European journal of endocrinology 2013, PMID 23447518

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.

Common questions

Does HGH help with sleep?

The strongest study we summarise for sleep is human rct evidence, across 3 studies with an outcome for sleep. A trial result is not an approval; see the legal status.

Is HGH approved for sleep?

HGH is FDA approved (prescription only). Which conditions that approval covers is set by the label; use for anything else is off-label.

What is the best peptide for sleep?

There is no single answer. Our sleep overview compares each candidate by evidence grade and legal status rather than by popularity.
