What did @genxshopfinds76 actually say?
Jen, who identifies as a nurse practitioner, tells her 86.5K viewers to "try salonk" (selank) if they're struggling with stress. She lists a striking range of claimed benefits: anxiety and depression relief, cognitive boosts for ADHD, antiviral effects against influenza A and herpes, gastric ulcer support, blood glucose reduction, and weight gain prevention. She also says selank lacks the sedative effects of "traditional medications" and that nasal administration is the primary route. That is a lot of claims packed into one short video, and not all of them hold equal scientific weight.
Does the science back this up?
Some of it does, partially, in animal models and small Russian trials. Selank is a synthetic heptapeptide derived from tuftsin, developed by the Russian Academy of Sciences. The anxiety-related evidence is the strongest, but it is still thin by Western regulatory standards.
The most cited work comes from Semenova et al. (2010, Bulletin of Experimental Biology and Medicine), which found anxiolytic effects in rodent models comparable to phenazepam but without sedation. That part of Jen's claim, the no-sedation angle, is actually supported by available data. Chait et al. (2022, Frontiers in Psychiatry) reviewed peptide-based anxiolytics and noted selank's favorable tolerability profile in small human trials conducted in Russia, though sample sizes were often under 60 participants.
The ADHD and cognitive boost claims are where things get thinner. There is no peer-reviewed trial in humans with ADHD diagnoses. The antiviral claims reference real preclinical data, but describing selank as having "antiviral effects like influenza A and herpes" to a general TikTok audience implies a clinical application that does not yet exist in evidence.
What did they get wrong (or right)?
Credit where it is due: the no-sedation claim is consistent with published data. The nasal route as the preferred delivery method is also accurate, given selank's poor oral bioavailability due to rapid enzymatic degradation in the gut.
Here is where it goes sideways. Jen lists blood glucose reduction, gastric ulcer support, and weight gain prevention as if these are established clinical uses. They are not. These effects appear in isolated preclinical studies, and presenting them as a benefit list to patients considering selank as an alternative to prescribed medication is irresponsible framing. The gastric ulcer reference likely traces back to tuftsin-related immunomodulatory research, which is a stretch to apply to selank directly.
The ADHD claim is the most problematic. No randomized controlled trial has tested selank in an ADHD population. Saying it "could give you a cognitive boost" for ADHD conflates nootropic potential with a clinical indication. That is a meaningful difference when your audience is a nurse practitioner's followers looking for medication alternatives.
Calling traditional medications sedating as a blanket contrast is also reductive. SSRIs, the first-line treatment for anxiety and depression, are not sedatives.
What should you actually know?
Selank is not FDA-approved for any condition. In the United States, it exists in a gray zone, available through compounding pharmacies operating under significant regulatory uncertainty. The FDA has taken enforcement action against some compounders marketing unapproved peptides, so the supply and legal status of selank can shift.
The research base is real but narrow. Almost all human trials were conducted in Russia between the 1990s and 2010s, published in Russian-language journals, and have not been independently replicated in large Western trials. That does not mean the research is fraudulent, but it does mean the evidence standard is well below what would be required for FDA approval or standard clinical guidance.
If you are managing anxiety, depression, or ADHD, selank is not a validated replacement for evidence-based treatments. Anyone considering it should have that conversation with a licensed provider who understands the current regulatory and evidence landscape, not a TikTok video.
