Selank and anxiety: what peptide TikTok gets wrong

What did @alexfraysse_coaching actually say?

The creator claims that selank, a synthetic peptide, works on "GABA receptor modulators" in the same way as benzodiazepines and SSRIs, and that it can replace those medications for people who struggle with anxiety. They say it "exerts a calming effect" and makes users feel like they have "more space in your system to breathe and to operate." They also mention it can be used subcutaneously or as a nasal spray.

There are real pharmacological threads here worth examining. But the framing, specifically the implication that selank is a functional equivalent to prescription anxiolytics, outpaces the actual evidence considerably. Let's break it down.

Does the science back this up?

Selank has real preclinical and limited clinical data behind it, mostly from Russian research institutes. The GABAergic mechanism is partially supported, but the SSRI comparison is not accurate at all.

Selank is a synthetic analogue of tuftsin, a naturally occurring tetrapeptide. Russian researchers, particularly Seredenin and Voronina, published work in the 2000s through the Russian Journal of Pharmacology showing selank modulates expression of GABA-A receptor subunits and influences serotonin metabolism in animal models. A 2001 study by Seredenin et al. in Eksperimental'naya i Klinicheskaya Farmakologiya reported anxiolytic effects in rodents without the sedation or dependence profile typical of benzodiazepines.

A small human trial published by Zozulya et al. (2001, Bulletin of Experimental Biology and Medicine) found selank reduced anxiety symptoms in patients with generalized anxiety disorder. The sample sizes were small, the trials were not blinded to modern standards, and almost none of this research has been replicated in large Western randomized controlled trials. That gap matters enormously when you're telling 2,200 people this is a solution for debilitating anxiety.

What did they get wrong (or right)?

The creator got the nasal spray delivery route right, and the general idea that selank has some GABAergic activity is not completely unfounded. That's where the credit stops.

Calling selank a GABA receptor modulator "the same thing as benzodiazepines" is misleading. Benzos are positive allosteric modulators of GABA-A receptors with well-characterized binding sites. Selank's influence on GABA signaling appears indirect, likely through gene expression changes rather than direct receptor binding. These are not the same mechanism.

The SSRI comparison is simply wrong. SSRIs work primarily by inhibiting serotonin reuptake at the presynaptic terminal. That is not a GABA mechanism. Selank does appear to influence serotonin metabolism in some animal studies, but lumping SSRIs into a "GABA receptor modulator" category misrepresents how antidepressants work at a basic pharmacology level.

The framing that this peptide "may be the solution" for people with anxiety severe enough to keep them housebound is the most concerning part. Presenting an under-studied compound as a substitute for evaluated treatments, without any mention of consulting a clinician, is a disservice to viewers who are actually struggling.

What should you actually know?

Selank is a legitimate research compound with an interesting pharmacological profile, but it is not an approved medication in the United States, the EU, or most Western countries. It is approved in Russia under the brand name Selank, primarily for anxiety and cognitive enhancement.

If you are dealing with anxiety that prevents you from leaving your house, that is a clinical situation. Selank has no Phase III trial data in large, diverse populations. The studies that exist are small, mostly Russian, and mostly older. That does not mean the compound has no value, but it does mean you cannot responsibly tell someone it is "the solution" for their anxiety disorder.

People who are avoiding SSRIs or benzos often have legitimate reasons, including side effect concerns or a preference for non-traditional approaches. Those preferences deserve serious engagement, not a TikTok that replaces one set of unanswered questions with another. Any exploration of selank or similar peptides should happen with clinical oversight, not a nasal spray ordered from a website after watching a short video.

The bottom line on selank and anxiety

Selank is a plausible research compound for anxiety with a modest evidence base and a reasonable safety profile in short-term studies. The mechanism claims in this video are partly grounded in real science but significantly oversimplified and in one case flatly wrong. The broader message, that this peptide can replace prescription treatments for severe anxiety, is not supported by current evidence and could discourage people from seeking appropriate care.

• The GABAergic activity claim has some basis in animal and small human studies.
• The SSRI mechanism comparison is pharmacologically inaccurate.
• No large, blinded, Western RCTs exist to support the efficacy claims made here.
• Selank is not FDA-approved and is not a substitute for evaluated anxiety treatments.
