A synthetic heptapeptide anxiolytic developed alongside Semax at Russia's Institute of Molecular Genetics, studied for generalized anxiety disorder and neurasthenia. Frequently paired with Semax in nootropic-peptide discussions.

Cognitive / nootropic · Mood / anxiety

Oxytocin

Limited human data

A naturally occurring hormone-peptide best known for its role in childbirth and lactation, popularized far beyond that as the "trust" or "bonding" molecule after a famous 2005 economics experiment. A useful case study in how a single influential paper can outrun its own replication record.

Mood / anxiety

Evidence labels

EmergingMostly preclinical or early signals; human athletic data is thin.
Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
Stronger clinical signalSupported by larger clinical trials in defined medical populations.

Same color code everywhere on STACKD: green = stronger clinical/human data, amber = limited human data or mechanism, slate = emerging/anecdotal, and oxblood = an in-house STACKD summary.
