Notes

Both administered intranasally for direct brain targeting. Semax enhances focus and BDNF. Selank reduces anxiety while improving cognition — useful for high-pressure work. Cycle to prevent tolerance. N-Acetyl Semax Amidate (NASA) is a more potent, longer-lasting version. Start with standard Semax before trying enhanced variants.
