What is semax spray?

It is the intranasal delivery form semax is typically sold and studied in, since the peptide has a short half life, on the order of minutes, that would not survive being swallowed or last long if delivered another way. Nasal delivery lets it reach systemic circulation and potentially the brain more directly than an oral dose would. This site's review found one human citation for semax, covering 110 participants.
