Nasal irritation and headache from N-Acetyl Semax amidate – any tips?

Posted by ivy_mobility in Safety & Side Effects - 1 points, 0 comments.

I started a low‑dose N‑Acetyl Semax amidate spray about two weeks ago, aiming for better focus during my night shifts. I used roughly 300 mcg split into two doses, one in the morning and one early afternoon. After a few days I noticed a mild burning feeling inside my nostrils that lingered for an hour or so, and sometimes a light headache that seemed to fade after drinking water.

I also felt a bit wired if I took the second dose later than 3 pm, which made falling asleep harder. I’ve tried rinsing with saline spray before each application and that seems to ease the irritation a little, but I’m wondering if others have found a better way to reduce the nasal discomfort or if splitting the dose differently helps with the overstimulation. Just sharing what I’ve seen so far, would love to hear what’s worked for you.
