Nootropic & Brain Peptides

Evidence-focused profiles for neuroactive peptides and peptide-adjacent compounds studied for cognition, mood, sleep or neuroprotection. Regional clinical reports, preclinical work and community claims are labeled separately.

Educational research reference only, not medical advice. Evidence strength and regulatory status vary substantially between compounds.

6 research profiles

Adamax

Adamax is best understood as a modified Semax-family nootropic rather than as an approved medication. The advertised purpose is longer-lasting cognitive and neuroprotective signaling after intranasal use, mainly by…

Cerebrolysin

Cerebrolysin is not one peptide. It is a mixture of low-molecular-weight neuropeptides and amino acids derived from porcine brain tissue. That makes it different from a single-sequence synthetic peptide with one…

Dihexa

Dihexa is a synthetic angiotensin-IV-derived compound marketed as a cognitive and neurorepair peptide. For a beginner, the key point is that it is not an approved medicine and not a clinically validated nootropic. It is…

DSIP / Emideltide

DSIP stands for delta sleep-inducing peptide. The FDA name used in the 2026 compounding review is Emideltide. It is a nine-amino-acid peptide that became famous because early rabbit experiments suggested it could…

Selank

Selank is a synthetic analog related to tuftsin and is discussed for anxiety, stress resilience, and cognition. It is commonly used intranasally in community settings. Evidence lens: There is regional clinical use and…
