Melatonin and Sermorelin: what the published research says

PubMed indexes 3 records that name Melatonin and Sermorelin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Melatonin and Sermorelin. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

3 studies naming Melatonin and Sermorelin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Effect of oral administration of melatonin on GH responses to GRF 1-44 in normal subjects.

Clinical endocrinology · 1987 · PMID 3115632

Clinical TrialRandomized Controlled Trial

“In contrast we did not observe any effect of either 10(-9)M, 10(-7)M melatonin on in-vitro basal GH release and GH responses to 10(-8)M GRF by rat anterior pituitary cells in monolayer culture. These data suggest that melatonin plays a facilitatory role in the neuroregulation of GH secretion, probably by acting at the hypothalamic level.”

Valcavi et al. · From the abstract

Names both Melatonin and Sermorelin in its title.

Melatonin modulates monochromatic light-induced GHRH expression in the hypothalamus and GH secretion in chicks.

Acta histochemica · 2016 · PMID 26948666

Animal study

“After pinealectomy, however, these parameters decreased and there were no significant differences between GL and the other monochromatic light treatments. These findings suggest that melatonin plays a critical role in GL illumination-enhanced GHRH expression in the hypothalamus and plasma GH concentrations in young broilers.”

Zhang et al. · From the abstract

Names both Melatonin and Sermorelin in its title.

Restoration of detectable melatonin after entrainment to a 24-hour schedule in a 'free-running' man.

Psychoneuroendocrinology · 1997 · PMID 9141150

Case ReportsHuman subjects

“This case raises the possibility that a complex interaction of light exposure with the circadian system can reversibly suspend pineal gland secretion of melatonin indefinitely. It also suggests that circadian rhythm disorders be considered in the differential diagnosis of abnormal endocrine function.”

Oren et al. · From the abstract

Names Melatonin and Sermorelin together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Melatonin, Sermorelin, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
