Sleep peptides

Peptides for Sleep: DSIP, Selank, and Epitalon

Sleep-related peptides are discussed across different mechanisms: sleep architecture, anxiety tone, circadian rhythm, and pineal signaling.

Mechanism

Different peptides point at different sleep problems

DSIP, Selank, and Epitalon are not interchangeable. They are discussed around different parts of the sleep system.

Some studies suggest DSIP may influence sleep architecture. Selank literature is often discussed around anxiety tone and calm. Epitalon literature is commonly linked to pineal and circadian signaling.

Use

What people track

People commonly track how long it takes to fall asleep, number of awakenings, perceived sleep depth, dreams, next-day mood, and next-day alertness.

The relevant endpoint depends on the sleep problem: onset, maintenance, circadian timing, or non-restorative sleep.
