The short answer
What is Selank?
Selank is a synthetic peptide based on the natural immune-regulating peptide tuftsin, developed in Russia and studied as an anxiolytic, meaning a calming agent, that does not carry the sedation or dependence associated with benzodiazepines. Research links its effects to GABA and serotonin signaling and to BDNF (Vyunova et al., 2018; Filatova et al., 2017), and a Russian clinical study compared its anxiolytic effect and tolerability with the benzodiazepine phenazepam in anxiety disorders (Medvedev et al., 2014). Outside Russia it is treated as a research compound, because the large independent Western trials common to approved drugs do not exist for it, which is the central caveat here. Published protocols describe intranasal and subcutaneous use in short courses, reported in units rather than mL, and those figures are what studies used, not a dose for anyone.
The Science
A Neuropeptide for Calm
Selank is studied for its influence on GABA, serotonin, and BDNF signaling, the systems involved in anxiety and mood. As with Semax, most of the research comes from Russian groups, so we frame it as promising rather than proven.
GABA & Serotonin
Studied for effects on the neurotransmitter systems that regulate anxiety and mood.
No Sedation
The studied profile is anxiolytic without the sedation associated with traditional anxiolytics.
Non-Dependence
Studied for a calming effect without the dependence profile of benzodiazepines.
Applications
Common Use Cases
Everyday Stress
Stress-response endpoints in generally healthy populations are the studied research area.
Focus Without Edge
Attention endpoints appear alongside the anxiolytic ones in the published work.
Semax Stack
Paired with Semax to balance focus with calm.
Sleep Wind-Down
Evening administration is described in reported protocols; it is not a studied endpoint of its own.
Dosage, as studied
What doses and routes did Selank studies use?
Published Selank protocols describe two routes, intranasal and subcutaneous, given in short courses rather than continuously. Intranasal, as drops or a spray, is the route most commonly described in the Russian literature (Medvedev et al., 2014). The table below summarizes how studies frame each route. It is a record of what the research describes, not a dose for any person, and every figure is reported in units rather than mL.
| Route | How studies describe it | Schedule |
|---|---|---|
| Intranasal | Drops or spray; most commonly described route | Short, pulsed courses |
| Subcutaneous | Injection; also appears in the literature | Short, pulsed courses |
We do not publish a milligram dosage chart for Selank: specific human dose figures are not well established in the limited independent record, and picking a dose is a clinical decision, not something to copy from a protocol. The reconstitution calculator works the concentration math for a 10mg vial so a studied amount can be read in units.
Comparison
Selank vs Semax: how do they compare?
Selank and Semax are sister peptides from the same Russian research tradition, and they are often studied and stacked together. The short version: Selank leans toward calm and reduced anxiety, while Semax leans toward focus and mental clarity. Selank is an analog of the immune peptide tuftsin studied as an anxiolytic acting on GABA and serotonin signaling (Vyunova et al., 2018); Semax is a fragment-based analog of the hormone ACTH studied for attention, memory, and BDNF.
| Feature | Selank | Semax |
|---|---|---|
| Parent molecule | Tuftsin (immune peptide) analog | ACTH(4-10) fragment analog |
| Studied focus | Anxiolytic (calm), GABA and serotonin | Attention, memory, BDNF |
| Common research angle | Calm and reduced anxiety | Focus and cognition |
| Routes studied | Intranasal, subcutaneous | Intranasal, subcutaneous |
| Evidence base | Mostly Russian research groups | Mostly Russian research groups |
Because their studied profiles complement each other, the two are frequently paired so calm does not tip into dullness and focus does not tip into overstimulation. See the Semax page for the focus side of the pairing. Neither is an approved drug, and any protocol is a decision for a licensed clinician.

What it is
Selank is a synthetic analog of the endogenous peptide tuftsin, studied for anxiolytic endpoints without a sedative profile.
Routes studied
Both intranasal and subcutaneous routes appear in the published work, with intranasal the more commonly described.
Pulsed courses
Published protocols describe short courses rather than continuous administration. The site reports those ranges and picks no schedule for anyone.
Evidence base
Most of the published clinical work comes from Russian research groups; large independent Western trials are limited. That gap is the central caveat on every figure below.

product arrived fine and both vials look good but my tracking number wouldn't load in the carrier's app at first. had to paste it into a browser search instead of scanning or typing it into their tracker. ended up working out, just an extra step i didn't expect. box itself was clean with no dents

one thing i want to highlight is that their team actually walked me through the research side of pt141 instead of just selling it to me. showed me the study, told me where the data was weak, answered every single question i threw at them over two days of back and forth before i committed to buying

i found them through a friend of a friend who does travel medicine and just happens to keep a running list of peptide vendors that actually publish their own lab sheets instead of linking out to somebody else. first order, arrived in about the window they quoted which felt reasonable for an international haul like this one

the tray had a small burr on one edge where the plastic did not get cut all the way through. nothing sharp enough to actually do anything but you could feel it running your finger along the rim, which is not how these should come out of the mold i would think. vials both fine otherwise and the rest of the packaging was solid

my yoga instructor mentioned them offhand once while we were chatting about recovery after class and i totally forgot until a week later. went home and searched for their third party lab results, found the reports, ordered from here to be safe on timing. package arrived in four days, box clean no dents, vials clear with proper cap seals
