Selank
Cognitive · TP-7
Verdict
promisingThe promising label reflects genuine but geographically narrow human data: small clinical studies out of Russia reported an anxiety-reducing signal, and the mechanism has real research behind it, but the trials are small, mostly unreplicated outside Russia, and no large Western RCT has confirmed the effect.
Quick answer
Selank is a synthetic peptide derived from the immune fragment tuftsin, developed in Russia as an anxiolytic. It is commonly researched for anxiety, focus, and stress resilience, and early human studies reported an anxiety-reducing signal comparable to a common benzodiazepine but without the sedation in those small trials. The catch: the data is thin and mostly regional, it is not FDA-approved, and it is sold for research use only.
- Class
- Synthetic heptapeptide; tuftsin analog (anxiolytic / nootropic research peptide)
- Half-life
- very short in blood (minutes, reported); effects reported to outlast plasma levels
- FDA status
- Not FDA-approved. Registered and used clinically only in Russia; in the United States it is not approved for any use and is sold for laboratory research use only.
- WADA banned?
- No
Which form actually works?
Intranasal (nasal drops / mist)
Promising
The form used in the Russian clinical research and the one most people ask about, because a nasal route is thought to help a fragile peptide reach the brain. This is where the anxiety-reduction signal was reported, and where reported effects such as a subtle calm-focus are described. The evidence is real but small and mostly regional.
Injectable (subcutaneous)
Unproven
Sometimes sold and discussed for research, but the human anxiety data rests on the nasal form, so the injectable route carries less of the studied evidence behind it. Treat claims about it as less supported than the nasal literature, not more.
