Selank
A Russian-developed synthetic heptapeptide registered as an anxiolytic in Russia — with consistent animal data and small human trials, but no independent replication outside Russian research groups
Cognitive & Sleep Peptides
Peptides targeting cognition, mood, anxiety, and sleep. Cerebrolysin is approved in many countries for stroke and dementia; Selank and Semax are Russian-registered for anxiety/cognition; DSIP has thin modern evidence despite the name. Quality and approval status differ widely.
Peptides in this category
Semax
A Russian-developed synthetic heptapeptide registered for stroke and neurological disorders in Russia — with genuine human clinical data, but almost entirely from Russian research groups and with no independent Western replication
DSIP: Delta Sleep-Inducing Peptide
Nine-amino-acid peptide first isolated in 1977 from rabbit cerebral venous blood during delta sleep. Modest human trial evidence for sleep and stress modulation.
Cerebrolysin: Porcine Brain Peptide Mixture for Neurorecovery
Mixture of low-molecular-weight peptides and amino acids derived from purified porcine brain protein. Approved in many countries for stroke and dementia; evidence is mixed.
