Sleep

Research compounds studied for supporting growth hormone release during sleep, restoring circadian rhythm function, and improving sleep architecture and quality.

Most researched for Sleep

Ipamorelin

The most widely used entry point for sleep-focused GH protocols. Selectively stimulates a clean GH pulse via ghrelin receptors without meaningfully raising cortisol or prolactin - making it more precise than older GHRPs. When taken 30 minutes before sleep, the GH pulse aligns with natural slow-wave sleep cycles.

Sermorelin

aka GHRH (1-29), GRF 1-29, Geref

PopularApproved

Sermorelin, sold under the brand Geref, is a synthetic peptide identical to the first 29 amino acids of human growth hormone releasing hormone, the portion responsible for its activity. It binds GHRH receptors in the pituitary and stimulates the natural production and release of growth hormone. It was FDA approved for evaluating pituitary function and for growth hormone deficiency in children, but the branded product was later discontinued for commercial reasons.

How it works: It activates pituitary growth hormone releasing hormone receptors, prompting the gland to secrete growth hormone naturally.

MK-677

aka Ibutamoren, MK-0677, Nutrobal

ModerateIn clinical trials

MK-677, also called ibutamoren, is an orally active non-peptide compound that mimics the hormone ghrelin and acts as a growth hormone secretagogue. In human trials it raised growth hormone and insulin-like growth factor 1 levels and increased fat-free mass. It is not a peptide and it is not approved for human use. Documented effects include increased appetite, fluid retention, and reduced insulin sensitivity.

How it works: It activates the ghrelin receptor in the pituitary and hypothalamus, stimulating release of the body's own growth hormone.

Oveporexton

aka TAK-861

ModeratePhase 3

Oveporexton is an investigational oral small molecule that selectively activates the orexin receptor 2. It is being developed for narcolepsy type 1, a disorder caused by loss of orexin-producing neurons. Two pivotal phase 3 trials reported improvements across wakefulness, daytime sleepiness, and cataplexy measures versus placebo. It is not approved; a new drug application is under FDA priority review.

How it works: It is a selective orexin receptor 2 agonist that restores deficient orexin signaling in narcolepsy type 1 to promote wakefulness.

Ipamorelin

aka IPA, NNC 26-0161

ModeratePreclinical

Ipamorelin is a synthetic pentapeptide that acts as a selective growth hormone secretagogue, binding the ghrelin receptor to trigger release of growth hormone from the pituitary. Unlike some related compounds it does not meaningfully raise cortisol or prolactin. It was investigated in human trials for postoperative ileus but development was discontinued after it did not show clear efficacy, and it is not approved for any use.

How it works: It selectively activates the ghrelin receptor on the pituitary to stimulate growth hormone release.

Pinealon

aka EDR, Glu-Asp-Arg

AdvancedPreclinical

Pinealon is a synthetic tripeptide of glutamate, aspartate, and arginine, also called EDR, from the Khavinson family of short peptide bioregulators. Research suggests it may enter cells and bind DNA promoter regions, influencing expression of genes tied to neuronal survival and oxidative stress. It has been studied in cell and animal models mainly for neuroprotection, cognitive function, and cellular aging processes.

How it works: It is thought to enter cells and bind DNA promoter regions, modulating expression of genes involved in neuronal survival and oxidative stress.

Sermorelin + Ipamorelin

AdvancedPreclinical

This entry is a combination of two separate peptides rather than a single molecule. Sermorelin is a synthetic analog of the first twenty-nine amino acids of growth-hormone-releasing hormone, and ipamorelin is a selective growth-hormone secretagogue acting as a ghrelin receptor agonist. They are paired in research to promote pituitary growth hormone release through complementary pathways.

How it works: It pairs a GHRH analog with a selective ghrelin receptor agonist to stimulate pituitary growth hormone release.

DSIP

aka Emideltide, Delta sleep-inducing peptide, WAGGDASGE

AdvancedPreclinical

Delta sleep-inducing peptide is a naturally occurring nonapeptide first isolated in 1974 from the blood of sleeping rabbits. Its mechanism is not fully understood, but it appears to influence sleep-regulating and stress-response pathways and is degraded quickly in blood. It has been studied in small human and animal experiments for sleep, stress, pain, and substance withdrawal, and it is not approved for any medical use.

How it works: It is an endogenous nonapeptide thought to modulate sleep-regulating and stress-response pathways, though its exact mechanism is unresolved.

CJC-1295 DAC

aka DAC:GRF, Modified GRF(1-29) with DAC

AdvancedPhase 2

CJC-1295 with DAC is a synthetic long-acting analog of growth hormone releasing hormone that carries a drug affinity complex, allowing it to bind serum albumin and circulate for days. It stimulates the pituitary to release growth hormone and raise IGF-1 over an extended period. It was tested in early human trials for its endocrine effects, but development was discontinued and it has no medical approval.

How it works: It binds serum albumin through a drug affinity complex and stimulates pituitary growth hormone release, raising IGF-1 for several days.

Cortistatin

aka CST-14, Cortistatin-14, CST-17

AdvancedPreclinical

Cortistatin is a neuropeptide structurally related to somatostatin that shares most somatostatin receptor binding while also engaging the ghrelin receptor. Preclinical research associates it with modulation of slow-wave sleep, cortical activity, and suppression of inflammatory and immune responses. It is studied as an endogenous signaling molecule rather than a marketed therapy, and human data remain limited.

How it works: It binds somatostatin receptors and the ghrelin receptor, modulating neuronal excitability, cortical rhythms, and immune signaling.

Epitalon Oral

aka Oral Epitalon

AdvancedPreclinical

This entry is an oral presentation of Epitalon, the synthetic tetrapeptide Ala-Glu-Asp-Gly modeled on a pineal preparation. It is the same molecule as the existing Epitalon row and is not a separate compound. Epitalon is studied for reported effects on melatonin, telomerase activity, and aging markers, largely in animal models and small human studies. Oral peptide bioavailability is generally low.

How it works: It is reported to influence pineal and neuroendocrine signaling and telomerase activity in preclinical work.
