Sermorelin (also known as GRF 1-29, GHRH 1-29) is one of the earliest GHRH analogs, historically used to assess GH function. This page covers what the published research does — and does not — establish about it in relation to sleep quality and recovery.
Sermorelin is researched for Sleep quality — which is why it appears in discussions of sleep quality and recovery.
Research status: Historical clinical use; well-characterized pharmacology.
How Sermorelin is thought to work
Sermorelin consists of the first 29 amino acids of GHRH — the active core of the hormone. It stimulates natural growth-hormone secretion and has a long clinical history, having been used diagnostically to evaluate pituitary growth-hormone function.
What it does not establish
Endocrine-active. Should only be considered under medical supervision.
Nothing on this page is a recommendation to use Sermorelin, and Selpho publishes no dosing, reconstitution or sourcing information. Read how we decide what goes in the library.

Supporting the body's own growth-hormone production, with interest in sleep quality and age-related GH decline. It has historical diagnostic use.
Both are GHRH analogs; CJC-1295 is engineered for a longer duration of action. Both are endocrine-active and should be used under medical supervision.
