Selank Side Effects: Safety Signals and Warnings
Selank safety concerns are compound-specific. The main listed side effects are Generally well-tolerated, Mild fatigue in some users, and Possible nasal irritation (intranasal). The main warning signals are Most clinical data from Russian research only, Not FDA-approved or evaluated, and Limited independent replication of results.
Direct Answer
Selank is the most practical entry point for research into anxiolytic peptides with any human evidence. It has Russian regulatory approval, an RCT in anxiety/cognitive impairment, and a benign side effect profile with no dependence or sedation. The limitations are real - all evidence is from Russian sources, no Western validation exists, and the intranasal half-life is under 5 minutes. But within its approved application (anxiety-driven cognitive impairment), it is the best-evidenced option in its class in this library.
