No specific receptor has been cloned, characterized, or reproducibly identified as the primary binding site… | Epithalon (AEDG; Ala-Glu-Asp-Gly) is a synthetic tetrapeptide modeled on the pineal polypeptide preparation epithalamin. Its proposed mechanism spans several parallel pathways. The human-relevant evidence is strongest for melatonin/circadian effects; the… | | Half-Life | ~7-15 minutes (IV; plasma clearance is rapid, though subjective sleep effects can outlast measurable blood levels) | Not well characterized in humans. As a small tetrapeptide, AEDG is expected to have a very short plasma half-life (on the order of minutes), while downstream gene-expression and circadian effects are thought to persist considerably longer.

The two differ in mechanism, half-life (~7-15 minutes (IV; plasma clearance is rapid, though subjective sleep effects can outlast measurable blood levels) vs Not well characterized in humans. As a small tetrapeptide, AEDG is expected to have a very short plasma half-life (on the order of minutes), while downstream gene-expression and circadian effects are thought to persist considerably longer. Any specific half-life figure should be treated as an unvalidated estimate.), and typical dose range. ### Which has the longer half-life, DSIP (Delta Sleep-Inducing Peptide) or Epithalon? DSIP (Delta Sleep-Inducing Peptide) has a half-life of ~7-15 minutes (IV; plasma clearance is rapid, though subjective sleep effects can outlast measurable blood levels). Epithalon has a half-life of Not well characterized in humans. As a small tetrapeptide, AEDG is expected to have a very short plasma half-life (on the order of minutes), while downstream gene-expression and circadian effects are thought to persist considerably longer. Any specific half-life figure should be treated as an unvalidated estimate..
