It is detected in brain and peripheral tissues and is noted for crossing the blood-brain barrier and for low toxicity in experimental systems. Despite its name, reported sleep effects have been inconsistent and its precise endogenous receptor remains incompletely defined. Areas of interest (largely from animal and small human studies) include slow-wave-sleep modulation, neuroendocrine signaling, stress responses, thermoregulation, and antioxidant effects. Research applications Probe in preclinical sleep and circadian research Neuroendocrine / stress-hormone signaling studies Thermoregulation and oxidative-stress research Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
