Russian intranasals, neurotrophic peptide complexes, and sleep peptides — what the clinical data actually shows.
Most nootropic peptides have a Russian clinical research base, dating from Soviet-era pharmaceutical development. Semax and Selank are intranasal heptapeptides approved in Russia for cognitive enhancement and anxiety. Cerebrolysin is a porcine-brain-derived peptide complex approved in 50+ countries for stroke and dementia. Dihexa and P21 are American academic spinouts targeting Alzheimer pathways.
Oxytocin is the most-studied of the cognitive peptides — investigated for social anxiety, autism, and PTSD with mixed but interesting data. DSIP, P21, and Pinealon remain firmly in the research-chemical category with sparse human evidence.
Pitocin · Syntocinon
The bonding hormone. Used investigationally for social anxiety, autism, and PTSD.
ACTH(4-10) Pro-Gly-Pro · Semax NA
Russian intranasal nootropic. ACTH(4-10) fragment. BDNF up-regulator. Best-studied in stroke.
Cerebrolysate · FPF-1070
Porcine-brain-derived neurotrophic peptide cocktail. Approved in 50+ countries for stroke and dementia.
TP-7 · Tuftsin analogue
Russian intranasal anxiolytic. Non-benzodiazepine. GABA-modulating without sedation or tolerance.
Delta Sleep-Inducing Peptide
9-aa neuropeptide. Investigated for chronic pain, alcohol/opioid withdrawal, and sleep architecture.
PNB-0408 · N-hexanoic-Tyr-Ile-(6) amino hexanoic
Hepatocyte growth factor mimic. Oral, BBB-permeable. Investigated for Alzheimer disease.
CNTF (148-163) · P021
CNTF fragment peptide. Investigated for neurogenesis and memory in Alzheimer models.
Glu-Asp-Arg · EDR
Pineal tripeptide. Khavinson bioregulator — sparse human data, used for neuroprotection.

Semax targets BDNF/NGF upregulation — useful for focus, motivation, and recovery from stroke. Selank targets GABA/serotonin modulation — useful for anxiety without sedation. They are sometimes stacked.
Cerebrolysin has decades of clinical use in Europe, Russia, and Asia. The most rigorous meta-analyses show modest but consistent benefits in stroke recovery; the dementia data is more variable.
Intranasal oxytocin shows acute effects on trust, social cognition, and stress reactivity. The clinical-trial literature in autism and PTSD is mixed — promising acute studies, less impressive long-term outcomes.
