Sleep Quality Peptides

MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics the action of ghrelin at the GHS-R1a receptor. Research focuses on increasing GH and IGF-1 levels, improving sleep quality, body composition, and bone density.

CJC-1295 is a synthetic GHRH (Growth Hormone-Releasing Hormone) analog with extended duration due to Drug Affinity Complex technology. Studied for its effects on growth hormone release and body composition.

Sermorelin is a synthetic 29-amino acid analog of growth hormone-releasing hormone (GHRH). It was FDA-approved for pediatric growth hormone deficiency and is widely used off-label for anti-aging and body composition optimization.

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied primarily in Russia. Research focuses on telomerase activation, pineal gland function, and potential anti-aging mechanisms.

Ipamorelin is a selective growth hormone secretagogue developed by Novo Nordisk. It stimulates GH release without significantly affecting cortisol or prolactin levels. Has been studied in clinical trials for postoperative recovery.

GHRP-6 (Growth Hormone Releasing Peptide-6) is a hexapeptide that stimulates growth hormone release through the ghrelin receptor. Known for potent GH release but also significant appetite stimulation.

DSIP is a naturally occurring neuropeptide first isolated from rabbit brain tissue. Research focuses on sleep induction, stress reduction, and neuroendocrine modulation. Shows complex, context-dependent effects.

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates growth hormone secretion. Considered more potent than GHRP-6 with less appetite stimulation.

Pinealon is a synthetic tripeptide bioregulator (Glu-Asp-Arg) developed in Russia, targeting pineal gland and central nervous system function. Research focuses on sleep regulation, neuroprotection, and cognitive function in aging subjects.
