How it works once Selank is available

  1. 1

    Share your health history

    Every treatment gets its own online clinical questionnaire — your history, medications, and goals.

  2. 2

    A licensed provider reads it

    A real person goes through your history and takes the time to get it right before anything is decided.

  3. 3

    They prescribe — or they don't

    If a treatment isn't right for your history, you'll hear that plainly. That review is the whole point.

  4. 4

    Your pharmacy compounds it

    Made for your prescription by a licensed U.S. pharmacy and shipped in temperature-safe packaging.

  5. 5

    You choose whether to continue

    Your care team checks in after it arrives. Adjust with your provider, or cancel at any time.

How Selank will be offered

Selank will be offered as a nasal spray. Your provider decides whether it's appropriate — including whether a different treatment would serve you better.

A tuftsin analog

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.

The literature is largely Russian-language

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.

Nasal, prescribed and reviewed

Selank is coming soon to Promise as a nasal spray. When visits open, a licensed provider will read your history, decide whether it fits, and may decline.

In brief.

Selank is coming soon to Promise as a compounded nasal spray — add me to the list. The standalone contains one peptide; Semax / Selank combines both peptides in one preparation and is listed separately. A licensed provider reviews every request and prescribes only when Selank is appropriate.

What Selank is

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 sits alongside DSIP, which comes at rest and recovery from an entirely different direction.

What the evidence base actually looks like

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.

The nasal formulation

Selank is coming soon as a nasal spray. The bottle strength is a product fact, not a public dosing schedule, and the provider sets any protocol after reviewing your history.

The standalone and Semax / Selank are different compounded preparations. The blend is not automatically stronger or better; a provider considers why one compound or the pair is being requested and whether either makes sense.

How a provider approaches it

One clinical question is why someone wants Selank without Semax beside it. The pair brings two different research pathways together, while the standalone narrows the formulation deliberately. A provider wants to understand that 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.

What treatment looks like

If Selank is prescribed, a licensed U.S. pharmacy compounds and dispenses the nasal spray. The provider sets the protocol, and follow-up check-ins keep the decision connected to your response.

The same gate applies as everywhere else on Promise: an intake written for the compound, a licensed provider reading it, and a prescription only when it genuinely fits.

Common questions

What is Selank?

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 coming soon to Promise as a compounded nasal spray.

Is this real Selank, or a research chemical?

A real prescription. Selank is coming soon to Promise, and when visits open, a licensed provider will review your history before deciding whether to prescribe it; if it is prescribed, a licensed U.S. pharmacy will compound the medication for you. It will not be a product labeled for laboratory use.

Does starting a visit guarantee a prescription?

No. A licensed provider reviews every Selank request and prescribes only when it is appropriate for you. If it isn't, you'll be told plainly — that review is the point.

How is standalone Selank different from Semax / Selank?

Standalone Selank contains one peptide in a nasal spray. Semax / Selank combines both peptides in one injectable preparation. A provider considers the clinical reason for using one compound or the pair rather than treating the blend as a stronger version.

Is Selank FDA-approved?

No. Selank is not FDA-approved. It will 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.

Do I need a prescription for Selank?

Yes. Selank is prescription-only, as everything on Promise is, and it is coming soon. Once visits open, a licensed provider reviews your intake — your health history, current medications, mental-health history, and what you are trying to address — and prescribes only if Selank is 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.

What does the evidence for Selank show?

Selank was developed in Russia, and most of its human literature was produced and published there. The studies exist, but many are small, difficult to appraise independently, and rarely replicated under contemporary Western trial standards.

How is this different from Selank sold online?

Selank sold online without a prescription is usually labeled for laboratory use, with no provider, no pharmacy, and no one accountable if something goes wrong. Promise uses a licensed provider review, a patient-specific prescription when appropriate, and a licensed U.S. compounding pharmacy.
