What is Semax?
Semax is a high-purity synthetic heptapeptide, an analogue of adrenocorticotropic hormone (ACTH) fragment 4-10, designed exclusively for laboratory research. With the sequence Met-Glu-His-Phe-Pro-Gly-Pro, Semax is utilized to investigate neuroprotective, nootropic, and stress-regulatory mechanisms. Supplied as a lyophilized powder for reconstitution, Semax provides researchers with a precise tool to study its effects on cognitive function, neuroprotection, and metabolic regulation in experimental models.

Research Applications:
Semax is extensively studied in preclinical research for its potential to enhance cognitive performance, reduce stress-induced metabolic disturbances, and support tissue repair in cellular and animal models. Investigations focus on its ability to modulate brain-derived neurotrophic factor (BDNF) and serotonin levels, which may mitigate stress-related overeating, supporting weight management studies. Research also explores its neuroprotective and anti-inflammatory effects, which could aid muscle recovery by reducing oxidative stress and inflammation associated with exercise or injury. Its role in improving mitochondrial function and metabolic health makes Semax a key compound for research into overall health, stress resilience, and recovery processes.
