Quick Answer
What is Selank? Selank is a synthetic heptapeptide (seven amino acids) derived from the immune peptide tuftsin. In research it is studied for anxiolytic (anti-anxiety) and nootropic pathways, including effects linked to GABA/serotonin signaling and BDNF in animal models. PrymaLab supplies it as a research-use-only 3ml pen at 1mg/ml.
This product is not for human or veterinary use; everything below describes laboratory and animal-model research only.
Selank is a tuftsin-analog heptapeptide studied in research for anxiolytic and nootropic pathways.
PrymaLab format: a preloaded 3ml autoinjector pen at 1mg/ml for reproducible, traceable measured delivery.
Selank vs Semax is a common comparison: both are Russian-developed research peptides, but Selank is tuftsin-derived while Semax is an ACTH(4-10) analog.
Research-use-only. Selank is not FDA-approved; published dosing refers to experimental models, not human protocols.
What Is Selank?
Selank is a synthetic heptapeptide โ seven amino acids โ based on the naturally occurring immune peptide tuftsin, with a modification that improves stability. It was developed by Russian researchers and is studied as a research peptide rather than an approved therapeutic in most jurisdictions.
For a laboratory, what is Selank means a defined research compound supplied at a reference concentration for reproducible in-vitro and non-human studies. PrymaLab presents Selank at 1mg/ml in a sealed 3ml autoinjector pen.
How Selank Is Studied to Work
Preclinical literature discusses Selank in the context of anxiolytic (anti-anxiety) and nootropic pathways, including interactions linked to GABA and serotonin signaling, BDNF expression, and immune modulation related to its tuftsin origin. These mechanisms are observed mainly in animal models and remain under investigation.
Why Researchers Choose the PrymaLab Selank Autoinjector Pen
PrymaLab supplies Selank in a preloaded 3ml autoinjector pen calibrated to 1mg/ml, giving laboratories a uniform, repeatable format for in-vitro and non-human research. The sealed pen supports clean handling, measured delivery, and clear record-keeping across replicates.
- Fixed 1mg/ml reference concentration for reproducible study design.
- Measured delivery for reproducible volumes and reduced variability.
- Optional glass reloading cylinder to standardize preparations between runs.
- Batch traceability linking every draw to a single reference batch.

How to Handle and Store the Selank Research Pen
Follow these laboratory handling steps when receiving and using the research-use-only Selank autoinjector pen. These describe lab handling only and are not human-use instructions.
- Receive and inspect. Confirm the Selank pen is sealed, the batch number is legible, and the solution is clear before logging it into inventory.
- Refrigerate and protect from light. Store the preloaded pen at 2-8ยฐC away from light; avoid freeze-thaw cycles that can degrade the heptapeptide.
- Record the batch. Log lot number, concentration (1mg/ml), and receipt date so each measured delivery traces to one reference batch.
- Dispense measured volumes. Use the pen’s measured-delivery mechanism to draw reproducible volumes into your in-vitro or non-human preparation, documenting each draw.
- Standardize with the reload cylinder. Where supplied, use the glass reloading cylinder to refill and keep the Selank preparation consistent across replicates.
- Track stability and dispose. Record the open date, monitor working stability per protocol, and dispose of the research material via your laboratory chemical-waste process.
Selank vs Semax: How Researchers Compare Them
Selank vs Semax is one of the most common comparisons in this category because both are Russian-developed research peptides often studied for neurological pathways. They are distinct molecules, as the table shows.
| Attribute | Selank | Semax |
|---|---|---|
| Origin peptide | Tuftsin analog (immune peptide) | ACTH(4-10) analog (adrenocorticotropic fragment) |
| Common research framing | Anxiolytic / anti-anxiety models | Nootropic / neuroprotective models |
| Typical study pairing | Frequently compared with Semax | Frequently compared with Selank |
| PrymaLab format | 3ml pen, 1mg/ml | 3ml pen, 1mg/ml |
| Status | Research-use-only | Research-use-only |
Researchers studying both often run them in parallel; PrymaLab supplies each in the same 3ml 1mg/ml pen format to simplify comparative study design.
What the Research Studies: Selank “Benefits” in Context
Searches for Selank benefits usually mean: what have preclinical studies explored? In animal and in-vitro models, Selank research has examined areas including:
- Anxiolytic (anti-anxiety) behavioral models
- Nootropic and memory-related pathways
- GABA / serotonin signaling interactions
- BDNF expression and immune-modulation (tuftsin-related) research
These are research observations, not established human outcomes. PrymaLab makes no therapeutic claims and provides no human dosing guidance; any โSelank dosageโ figures in the literature refer to controlled experimental models.
Selank Side Effects & Legal Status in Research Settings
Reported Selank side effects derive from experimental and limited clinical studies, and a complete safety profile is not established for general use. Selank is not approved by the FDA and is handled as a research compound. Confirm the legal status of Selank in your jurisdiction before purchase.
