CJC-1295
Limited human dataA 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 dataA selective growth hormone secretagogue (ghrelin-receptor agonist) discussed for GH pulses with a relatively favorable selectivity profile in older literature.
Muscle / GH axis · Recovery · Sleep / recovery adjunct
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
EmergingA 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.
Same color code everywhere on STACKD: green = stronger clinical/human data, amber = limited human data or mechanism, slate = emerging/anecdotal, and oxblood = an in-house STACKD summary.
