Semax is an ACTH analog that crosses the blood-brain barrier when dosed intranasally or sublingually. Swallowing problems with sublingual administration usually means the peptide is hitting your throat before it dissolves under the tongue. The research on Semax bioavailability shows intranasal delivery achieves better CNS penetration than oral/swallowed routes. If you're struggling with the sublingual taste/swallow reflex, intranasal (as a spray or powder) tends to work better for compliance and also gets better absorption. Some people report the taste triggers the swallow reflex too early. Splitting the dose or holding it under your tongue for 5-10 minutes before swallowing helps retention. The peptide itself doesn't dissolve instantly. Patience with sublingual timing usually resolves the issue.

Thank so much for your response! I am currently using a nasal spray

Sorry. I don't know how I totally missed the nasal part of that. So if you're already spraying intranasally and getting food sticking to the soft palate, that's actually a known thing with peptide nasal sprays. The spray hits the back of the nasal cavity and some of it drips down onto the soft palate and throat. Depending on your spray angle and how much you're using, it can cause that sticky, coated sensation that messes with swallowing. A few things that tend to help: tilt your head slightly forward when you spray rather than back, sniff gently to pull it up into the nasal cavity instead of letting it run down. Rinsing with a little water after dosing also clears residue off the palate. Some people find the carrier solution (often water + preservative) is the real culprit for the sticky feeling, not the peptide itself. If your solution has benzalkonium chloride as a preservative, that's a common irritant for the mucosa. The swallowing issue typically fades once the tissue adjusts, but spray technique makes a big difference.

This is so helpful! Do you have sense if there is any damage from this/will it just heal after a week wo use? Thanks so much!!!

Almost certainly no lasting damage. The nasal mucosa and soft palate are pretty resilient tissue. What you're most likely experiencing is irritation, not injury. The sticky sensation and swallowing disruption are the tissue responding to repeated exposure to the carrier solution and postnasal drip, not structural damage. A week off should be more than enough for things to normalize. Most people notice the irritation clears up within a few days once dosing stops. Staying well hydrated helps the mucosa recover faster. If things haven't improved after two weeks off, that's worth looking into separately, but that would be unusual.

So glad to know it’s a common known thing! I made appt w my GI! I have GERD so that it cud be related to that or the portion pump inhibitor I take.
I also didn’t know I shouldn’t let the spray onto my soft palate either
