How Long Does Selank Last? Shelf Life & Stability
"Stable" is meaningless without saying stable against what. Selank has its own set of degradation routes, and they determine which storage precautions actually matter for it.
In plain English
Chemically this is one of the more relaxed compounds here. No light sensitivity, no oxygen sensitivity. Its real loss route is not chemical at all — material sticking to surfaces. That looks exactly like weak product in a result, while nothing has actually broken down.
What Selank actually is
Selank came out of the same Moscow programme as Semax, built from tuftsin — a tiny natural fragment released from antibodies — with the same stabilising tail added. Its research literature centres on anxiety-related behaviour and the brain signalling systems associated with it.

Degradation routes specific to Selank
- Adsorption to glass and untreated plastic — the practically significant loss route for this cationic peptide at low concentration, not a chemical degradation at all.
- Slow backbone hydrolysis over extended solution storage.
- Microbial growth if reconstituted in non-preserved water.
Selank is chemically one of the more forgiving peptides here. Its handling risk is physical loss to surfaces rather than molecular breakdown, which means the countermeasure is low-bind labware rather than light protection.
Freeze–thaw tolerance
Tolerant, but aliquoting is still the correct default for a multi-week study.
How storage addresses these routes
Practical window once reconstituted: 3–4 weeks at 2–8 °C — a longer window than most peptides of comparable size, precisely because it lacks oxidisable residues.
Full Selank storage conditionsWhat Selank is studied for
The most-populated area of the Selank literature, examined in behavioural anxiety models.
Studies have investigated interaction with both systems without the sedative profile of classical anxiolytics.
Its parent tetrapeptide is immunomodulatory, and some research follows that thread.
Investigated in learning and memory paradigms alongside its stress-response work.
