Can peptide therapy improve sleep quality during recovery cycles?

Growth hormone releasing peptides such as CJC-1295, ipamorelin, and sermorelin have been shown to enhance sleep architecture by increasing time spent in slow-wave deep sleep, which is the stage where most tissue repair and recovery occurs. Sermorelin specifically supports natural growth hormone rhythms, and GH secretion is closely tied to Stage 3 sleep responsible for physical restoration and immune repair. BPC-157 may indirectly support sleep by reducing neuroinflammation and supporting the gut-brain axis, which influences serotonin production. These peptides should only be used under medical supervision as they are not FDA-approved for general performance use.
