Cognitive & Neuroprotection

Dihexa

Dihexa (PNB-0408)

Research

A brain-focused compound studied for its dramatic effects on nerve connections in rodent models. Despite peptide-adjacent origins, it's chemically a small molecule — and it's never been tested in humans.

N-Acetyl Semax

N-Acetyl Semax Amidate

Research Phase

A chemically modified, longer-acting version of Semax, engineered for extended stability while aiming to preserve its cognitive and focus-supporting effects.

Oxytocin

Oxytocin

FDA Approved

The well-known 'bonding hormone' — and also a long-approved medication used in childbirth. Its social and emotional effects are studied separately from its approved medical use.

Pinealon

Pinealon

Research

A tiny three-amino-acid peptide from the same Russian research family as Epithalon, studied for protecting brain cells from age-related oxidative damage.

Selank

Selank (TP-7)

Approved (Russia/Ukraine)

A calming, non-sedating anxiety peptide from Russia. Eases stress and sharpens focus without the mental fog of typical anti-anxiety drugs.

Semax

Semax

Approved (Russia/Ukraine)

A Russian nootropic peptide that sharpens memory and focus, originally developed to help stroke patients recover.
