A synthetic tuftsin analog developed in Russia and studied around anxiolytic signaling, offered on Promise today only inside the Semax / Selank combination rather than on its own.
Coming soon
You are on the list. We will email you if Selank becomes available — and nothing else. Joining is not a medical request, and no prescription has been issued.
That did not go through. Check the address and try again.
Standalone Selank is not available yet; joining the waitlist tells us there is demand, and any prescription would still come from a licensed provider.
How it works once Selank is available
Every treatment gets its own online clinical questionnaire — your history, medications, and goals.
A clinician reads your history and takes the time to get it right before anything is prescribed.
Compounded for your prescription and shipped cold-chain, with care-team check-ins after.
Selank is easy to find online and hard to trust there. Promise works the way medicine is supposed to work — a clinician decides, a licensed pharmacy fills, and someone stays accountable to you.
Prescribed for you specifically, after a real look at your health history — never pulled off a shelf.
Your prescription is compounded for you by a licensed U.S. pharmacy — not a mystery vial from an unregulated website.
Temperature-safe shipping, follow-up check-ins, and a care team that answers — before and after your medication arrives.
Selank is built from tuftsin, a naturally occurring immune-active peptide fragment, with a short tail added to slow its breakdown. Research interest centers on GABAergic and serotonergic signaling.
Selank was developed in Russia and most of its human research was published there. That work is real, but it is thin by Western regulatory standards and hard to appraise independently.
Standalone Selank cannot be prescribed through Promise today. Anything in this category is a provider's call after reviewing your history.
Selank is not available on its own through Promise. Today it reaches patients one way only, inside the Semax / Selank combination, where both peptides sit in a single compounded preparation. This page is for the standalone, which does not exist here yet.
There is no intake questionnaire for it, no price, and no date. What follows is a description of the compound and an honest account of what is known about it.
Selank is a synthetic analog of tuftsin — a short peptide fragment that occurs naturally in the body and has a recognized role in immune signaling. The analog keeps the tuftsin sequence and adds a small proline-glycine-proline tail, which slows enzymatic breakdown and gives the molecule enough working life to be studied.
Research interest centers on anxiolytic signaling: how the peptide appears to modulate GABAergic transmission, and separately on serotonergic and neuropeptide activity. It is not a sedative and it is not a benzodiazepine, and the research does not read it as either. It is studied as a modulator, which is a much more modest description than it sometimes gets online.
Within our calming and stress relief category it would sit alongside DSIP, which comes at rest and recovery from an entirely different direction.
This is the part worth reading carefully. Selank was developed at a Russian research institute and the great majority of its clinical literature was produced and published there, in Russian. Those studies exist and some of them are human trials, but they are small, they are difficult to appraise from outside, and very few have been replicated in Western settings under contemporary trial standards.
That is not a claim that the work is wrong. It is a statement about how much weight it can carry. A compound with a plausible mechanism and a thin, hard-to-audit evidence base is exactly the kind of thing that belongs behind a clinician.
We will not describe Selank as a treatment for anxiety, because that is not a claim the available evidence supports and not a claim we are permitted to make. Anxiety is a real condition with real treatments, and a person who has it deserves a proper clinical assessment.
A treatment goes live on Promise only when three things line up: a pharmacy willing to compound that specific preparation, a clinical intake questionnaire written for it, and a provider network prepared to prescribe it. The combination has all three. The standalone has none of them, because it is a different formulation with a different clinical question behind it.
So we are not taking requests for standalone Selank, and we are not going to name a date we cannot keep. The waitlist measures one thing: whether enough people want it separately to justify building the formulation, the questionnaire, and the review process from scratch.
If the standalone were ever offered, the interesting clinical question would be why someone wants Selank without Semax beside it. The pair was assembled to work along two different axes at once; separating them is a deliberate narrowing, and a provider would want to understand the reason.
They would also want your full picture — current medications, particularly anything acting on serotonergic pathways, and your mental-health history. A licensed provider reviews every request and prescribes only when treatment is appropriate.
For now, the honest position is straightforward. Selank is available here only as part of Semax / Selank. The standalone is an idea with a waitlist attached, nothing more, and we would rather tell you that than let the page imply a treatment is waiting for you.
If it does become available, the same gate will apply as everywhere else on Promise: an intake written for the compound, a licensed provider reading it, and a prescription only when it genuinely fits.
Selank is a synthetic analog of tuftsin, a short naturally occurring peptide fragment with a known role in immune signaling. The analog adds a small tail to the sequence, which slows how quickly enzymes break it down. Research interest centers on anxiolytic signaling and on modulation of GABAergic and serotonergic pathways. It was developed in Russia and is not available on its own through Promise.
The published intake and the compounded formulation we currently offer are for the pair. [Semax / Selank](/products/semax-selank) is prescribed as one preparation, with both peptides in the same vial, because that is how the combination was sourced and how the clinical questionnaire was written. A standalone Selank preparation would need its own formulation and its own intake, and neither exists yet.
There is no committed date, and we are not taking requests for it. A treatment goes live here only once a pharmacy will compound it, a clinical intake questionnaire has been written specifically for it, and the provider network is willing to prescribe it. The waitlist exists so we can gauge whether enough people want the standalone to justify building all three.
No. Selank is not FDA-approved. It would be prepared as a compounded medication, and compounded medications are not reviewed by the FDA for safety, effectiveness, or quality. Selank has never been through a U.S. approval process, and the research supporting it was largely conducted and published in Russia.
Yes. Selank would be prescription-only, as everything on Promise is. A licensed provider would review your intake — your health history, current medications, mental-health history, and what you are trying to address — and prescribe only if Selank were appropriate for you. If your answers point toward a diagnosable anxiety or mood condition, the right response is care from a clinician who can treat it, not a compounded peptide, and a provider will say so and decline.
