Best Peptides for Circadian Rhythm

Orally active ghrelin receptor agonist (not a peptide). Boosts growth hormone and IGF-1. Known for improving deep sleep, increasing appetite, and gradually improving body composition.

One of the cleanest GH boosters. Stimulates growth hormone release without affecting cortisol or prolactin, meaning fewer side effects than other GH peptides.

Longevity peptide from the pineal gland. Activates telomerase to protect DNA caps and restores melatonin production. Russian studies showed 11-16% lifespan increase in animals.

Brain peptide that promotes deep delta-wave sleep. Normalizes disrupted sleep patterns and reduces stress without next-day grogginess.

Pre-mixed Ipamorelin + CJC-1295 combo. Works through complementary pathways for strong, clean GH release. The gold standard starter stack for GH optimization.

One of the most prescribed GH peptides. Copies the first 29 amino acids of natural GHRH, triggering physiological GH pulses from the pituitary.

Long-lasting growth hormone booster. The DAC modification keeps it active for days, producing steady GH elevation for muscle growth, fat loss, and recovery.

Stronger GH release than GHRP-6, with more moderate appetite increase. Raises both GH and IGF-1, though it can slightly bump cortisol and prolactin.

Critical molecule for cellular energy and DNA repair. Levels may drop ~50% by middle age. Activates sirtuin longevity genes and powers PARP DNA repair enzymes. Injectable form bypasses oral absorption issues.
