Showing 4 peptides tagged Sleep / recovery adjunct.

CJC-1295

Limited human data

A growth hormone-releasing hormone (GHRH) analogue discussed for GH-axis support. Often mentioned with ipamorelin in fitness forums as a commonly discussed pairing.

Ipamorelin

Limited human data

A selective growth hormone secretagogue (ghrelin-receptor agonist) discussed for GH pulses with a relatively favorable selectivity profile in older literature.

DSIP (Delta Sleep-Inducing Peptide)

Emerging

A nonapeptide isolated from rabbit cerebral venous blood in the 1970s and named for its apparent sleep-promoting effect in early animal work. One of the oldest "sleep peptides" discussed online, though its own reviewers call its biological role "a still unresolved riddle."

Sleep / recovery adjunct

Epitalon

Emerging

A synthetic tetrapeptide associated with pineal peptide research and aging biology conversations. Evidence is largely historical/preclinical with limited modern RCT coverage.

Evidence labels

  • EmergingMostly preclinical or early signals; human athletic data is thin.
  • Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
  • Stronger clinical signalSupported by larger clinical trials in defined medical populations.

Anodized by evidence strength: blue = stronger clinical/human data, violet = limited human data or mechanism, steel = emerging/anecdotal, and amber = an in-house STACKD summary.
