Goals / Sleep

Goal guide

Sleep

Growth hormone release is tied to deep sleep, which is why sleep comes up in growth-hormone peptide research. Direct sleep evidence is limited.

Foundations first

No peptide replaces these. They drive most of the results.

Peptides researched for sleep

Ranked from strongest to earliest-stage evidence.

GHRH analog

Sermorelin

A short GHRH fragment with a long research history.

Human clinical trialsLong-acting GHRH analog

CJC-1295

A modified GHRH analog engineered to last longer in the body.

Early human researchGrowth hormone secretagogue

Ipamorelin

A selective ghrelin-receptor agonist that stimulates growth hormone release.

Early human researchSynthetic tetrapeptide

Epitalon

A four-amino-acid peptide studied in aging research, largely by one research group.

Mostly animal research
