Sleep-enhancing peptides exert systemic effects by acting on circadian regulators (e.g., CLOCK, BMAL1), restoring pineal-mitochondrial signaling, and enhancing endogenous GH release (Table 3)

This pattern is consistent with what researchers would expect for a compound where placebo effects, injury variability, and administration differences all contribute noise to self-reported outcomes
