About This Desk

What this desk covers

nasalpeptides reads the published research on three structurally unrelated neuropeptides — Semax, Selank, and DSIP — organized around a shared experimental feature: each has been studied, at least in part, by intranasal administration. That is an organizing lens, not a claim that the three compounds work alike, are equally studied, or are interchangeable. Semax is researched for neuroprotection and cognition, Selank for anxiolysis, and DSIP for sleep, and each page treats its compound on its own terms.

Each compound holds its own page; a comparison page lays the three side by side; a shared FAQ answers the questions readers most often bring; and one shared reference list gathers every source drawn on across the site. None of the three peptides is FDA-approved. Two — Semax and Selank — are registered pharmaceuticals in Russia; DSIP has never been approved by any regulator anywhere despite carrying an assigned International Nonproprietary Name.

How the desk is written

Three rules govern what appears on this site.

Every factual claim traces back to a cited source. Numbered citations point to peer-reviewed, PubMed-indexed articles with DOIs and PubMed links wherever available, gathered on the references page. Where a claim comes from a review article rather than a primary study, the text says so.

Findings are reported at the scale they were studied. A rat study is described as a rat study; a six-person human pilot trial is described as a six-person human pilot trial. Where a compound's evidence is thin, old, or confined to a single research lineage — as with much of the DSIP and Semax literature — this site says so plainly rather than implying a larger or more current evidence base than exists.

Anecdote is always labeled as anecdote. Community-reported benefits and side effects appear on each compound page, clearly marked as anecdotal and not clinical evidence, and never attached to a specific human dose.

The edges of this desk

nasalpeptides is not a pharmacy, clinic, telehealth platform, or vendor of any kind. Nothing here is sold, supplied, sourced, or brokered — no compound, no research chemical — and no supplier or clinic pays for a place on this site. No clinician is on staff; nothing is diagnosed and nothing is prescribed, and no dose, schedule, or nasal-spray protocol is given for any person to follow. Where a study describes a specific intranasal dose, this site reports it as exactly that — a figure from a study, in an animal or a small trial cohort — never as a recommendation.

Anyone seeking clinical guidance on anxiety, sleep, or cognitive concerns should take it to a licensed provider in their own jurisdiction. Notes on citation fixes, stale references, or newly published studies are welcome by way of the contact page; that mail is read with care, but requests for medical advice cannot be answered.
