Sleep Quality Peptides
Improves sleep patterns and quality
Sleep peptides improve sleep quality through several distinct mechanisms: regulating sleep architecture (the pattern of light, deep, and REM sleep stages), reducing cortisol and anxiety that interfere with sleep onset, and increasing growth hormone release during deep sleep. DSIP (delta sleep-inducing peptide) is the most directly targeted, named for its ability to promote delta wave (deep) sleep. Selank and semax address sleep indirectly by reducing anxiety and normalizing stress hormones. Growth hormone secretagogues like ipamorelin and MK-677 enhance the GH pulse that naturally occurs during deep sleep.
Poor sleep is one of the most common complaints that leads people to research peptides, and improved sleep is often the first benefit reported with GH peptides, even before body composition changes appear. The distinction between sleep peptides is whether they target sleep directly or improve it as a secondary effect of other mechanisms.

Peptides (9)
CJC-1295 (Modified GRF 1-29)
CJC-1295 without DAC (also called Modified GRF 1-29) is a synthetic growth hormone-releasing compound with a short active window of about 30 minutes. It is being studied for its effects on growth hormone release and body composition.
MK-677 (Ibutamoren)
MK-677 (Ibutamoren) is an oral (non-injectable) compound that triggers growth hormone release by mimicking the hunger hormone ghrelin. Research focuses on increasing growth hormone and IGF-1 levels, improving sleep quality, body composition, and bone density.
Sermorelin
Sermorelin is a synthetic 29-amino-acid growth hormone-releasing compound. It was FDA-approved for pediatric growth hormone deficiency and is widely used off-label for anti-aging and body composition improvement.
Epitalon (Epithalon)
Epitalon is a synthetic four-amino-acid peptide studied primarily in Russia. Research focuses on activating telomerase (an enzyme that maintains chromosome caps), supporting pineal gland function, and potential anti-aging effects.
Ipamorelin
Ipamorelin is a selective compound that triggers growth hormone release, originally developed by Novo Nordisk. It stimulates growth hormone without significantly affecting cortisol or prolactin levels. It has been studied in clinical trials for postoperative recovery.
DSIP (Delta Sleep Inducing Peptide)
DSIP (Delta Sleep Inducing Peptide) is a naturally occurring brain peptide first isolated from rabbit brain tissue. Research focuses on sleep promotion, stress reduction, and hormone regulation. It shows complex effects that vary depending on the context.
GHRP-6
GHRP-6 (Growth Hormone Releasing Peptide-6) is a six-amino-acid peptide that triggers growth hormone release through the ghrelin (hunger hormone) receptor. It is known for strong growth hormone release but also significant appetite stimulation.
GHRP-2
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic six-amino-acid peptide that triggers growth hormone release. It is considered more potent than GHRP-6 with less appetite stimulation.
Pinealon
Pinealon is a synthetic three-amino-acid peptide that may help regulate pineal gland and central nervous system function. Developed in Russia, research focuses on sleep regulation, brain cell protection, and cognitive function in aging.
