What it is
An acetylated, often amidated Selank analog sold as a steadier anti-anxiety / focus nasal.
Benefits in plain language
What researchers and reference users usually mean when they talk about this compound. These are study themes and common claims — not a promise that it will do this in you.
- The hoped-for feeling is calmer thoughts without turning into a nap.
- Used in the same breath as Semax when someone wants “calm focus” rather than “loud focus.”
- Evidence is still the Selank family story, not a new Western approval.
If a branded, FDA-approved product exists, that label is the only dose that is actually authorized. Research-chemical vials are a different object.
Mechanism of action
Tuftsin-based immunomodulatory and GABAergic / enkephalin themes from Selank, with chemistry tweaks for stability.
Possible side effects / caveats
Nasal burn, odd taste, blandness or fatigue if the dose overshoots.
