Peptides
Cerebrolysin
Cerebrolysin
Cerebrolysin is a mixture of small peptides and amino acids derived from pig brain tissue, given by injection. It is approved in several countries for stroke and dementia, but large independent reviews have found the evidence mixed and often low quality.

PE-22-28
PE-22-28 is an experimental peptide derived from spadin, studied in animals for possible antidepressant and neuroprotective effects. There are no published human trials, so its effects and safety in people are unknown.
Read profileSelank
Selank
Selank is a synthetic peptide developed in Russia and studied there as an anti-anxiety agent given by nasal spray. Most evidence comes from Russian-language research, and there is little independent, well-controlled human data elsewhere.
Read profileSemax
Semax
Semax is a synthetic peptide developed in Russia, where it is used as a prescription nasal spray for stroke and cognitive issues. Most of the supporting research comes from Russian-language studies, and there is little independent, well-controlled data in other countries.
