Best Peptides for Cognitive Function Research: What the Studies Actually Show
Cognitive function is the least evidence-backed corner of peptide research. Unlike fat loss — where approved drugs have completed Phase 3 trials — the cognitive field is almost entirely preclinical, concentrated in Russian-language literature that is difficult to evaluate by international standards, and thin on human data. One entry on this list isn’t even a…

Selank Peptide Research: Benefits, Studies, and Evidence
Selank is a synthetic heptapeptide researched for its relationship with anxiety biology, GABAergic signaling, and neurotrophic and immune modulation. An analog of the naturally occurring immunoregulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended with a Pro-Gly-Pro tail, it emerged from the same Russian peptide-pharmacology program as Semax — and shares that program’s distinctive literature profile: deep, decades-long, and…
