In this episode, we explore why Sermorelin is often discussed in conversations about sleep, even though it is not a sleep aid in the traditional sense. The connection comes down to deep sleep and recovery biology. One of the most important growth hormone pulses occurs shortly after sleep begins and is closely tied to slow wave sleep, the stage responsible for overnight restoration.

We break down what Sermorelin is, why its upstream signaling role matters, and how it fits into sleep quality rather than sleep onset. We also explain why Sermorelin is often stacked with DSIP and Selank, with each peptide addressing a different layer of sleep depth, continuity, and stress regulation.

The focus of this episode is not sedation, but supporting quieter, deeper, more restorative nights and more stable mornings.
