Selank and Semax for ADHD and anxiety: what the research actually shows

What did @tukhatua actually say?

The creator walked viewers through reconstituting and injecting Selank and Semax at home, sourcing vials from a vendor called Flawless, and using a 31-gauge insulin syringe to draw what they describe as "5 units" of Selank and "6 units" of Semax daily. They claim Semax "is great for ADHD" and has helped them focus significantly, while adding the standard legal boilerplate: "I am not a doctor. I am just a researcher and a lab rat." That disclaimer does not change what the video is actually doing, which is instructing viewers how to inject unregulated peptides for neurological effects.

The video also covers sharps disposal, air-pressure equalization in vials, and drip-along-the-wall reconstitution technique. Some of this procedural content is actually reasonable harm reduction. The neurological efficacy claims are a different story entirely.

Does the science back this up?

For Semax and ADHD specifically, the answer is: not in any meaningful way for human clinical use. The evidence base is thin, Soviet-era, and almost entirely preclinical or conducted in Russia with limited external replication.

Semax is a synthetic heptapeptide analogue of ACTH(4-7) developed in the 1980s at the Institute of Molecular Genetics in Moscow. It is approved in Russia and Ukraine as a nasal spray for stroke recovery and cognitive impairment, not ADHD. Studies like Eremin et al. (2005, Neuroscience and Behavioral Physiology) and work by Dolotov et al. (2006, Journal of Neurochemistry) show Semax increases BDNF and influences dopaminergic pathways in rodents, which is the mechanistic basis for ADHD-adjacent interest. But rodent dopamine effects do not reliably translate to human ADHD treatment outcomes. No peer-reviewed randomized controlled trial in humans has established Semax as an ADHD therapy.

Selank is similarly a tuftsin-derived anxiolytic peptide with some Russian clinical data for generalized anxiety disorder (Zozulya et al., 2008, Bulletin of Experimental Biology and Medicine), but again, the research is predominantly Russian, small-scale, and not replicated in Western regulatory-grade trials. Calling this combo "top tier" for ADHD and anxiety overstates the evidence by a considerable margin.

What did they get wrong (or right)?

Wrong: The claim that Semax has "no bad side effects" is unverifiable and almost certainly false as a universal statement. Side effect data on subcutaneous Semax in uncontrolled home-use settings simply does not exist in any systematic form. Reported anecdotal adverse effects in online communities include anxiety spikes, irritability, and fatigue, particularly with Semax at higher doses. Saying there are no bad side effects because you personally haven't experienced them is not how pharmacology works.

Wrong: The "research only, not for human consumption" label is a legal fiction that the video immediately contradicts by showing the creator injecting these compounds and describing personal daily dosing. Regulators and courts have been increasingly skeptical of this framing.

Right, actually: The reconstitution technique itself is largely sound. Dripping bacteriostatic water down the vial wall rather than directly onto the lyophilized peptide cake is standard practice to avoid degradation. The rotation-not-shaking instruction is correct. The sharps disposal advice, including bringing full containers to a pharmacy, is responsible and worth crediting.

Right: The pressure-equalization step before drawing doses from a freshly reconstituted vial is a legitimate practical tip that reduces frustration and potential contamination from repeated needle insertions.

What should you actually know?

These peptides are not FDA-approved for any indication. They are not available through licensed U.S. pharmacies as finished drug products. Purchasing them from research chemical vendors like the one mentioned in this video means you are getting compounds with no guaranteed sterility, potency, or purity verification by any independent regulatory body. A 2023 analysis of research peptide vendors by Valisure found significant concentration inaccuracies and contamination in a substantial proportion of samples tested.

The ADHD framing is particularly concerning because people with ADHD are already a population that has historically been targeted by unproven treatments. If you are managing ADHD symptoms, there are well-studied, FDA-approved pharmacological and behavioral options. Self-injecting an unregulated Russian neuropeptide because a TikTok creator says it helped their focus is not a reasonable substitute for an evaluated treatment plan.

The "lab rat" framing is also worth examining critically. It sounds humble and self-deprecating, but it normalizes the idea that self-experimentation with injectable compounds is a reasonable consumer activity rather than something that carries genuine risks, including infection, dosing errors, and interactions with other medications or conditions the viewer may have.
