Cognitive & Longevity Research

RetaPep’s Cognitive & Longevity Research category brings together compounds studied for neuroprotection, cognitive enhancement, and cellular aging mechanisms. Products include Semax, Selank, Epithalon, NAD+, DSIP, and the Semax + Selank combination stack — all supplied at >=99% purity with CoA documentation.

Semax, an ACTH(4-10) analog, has been extensively researched for its role in BDNF expression, memory consolidation, and neuroprotective signalling. Selank, a tuftsin-derived heptapeptide, is studied for anxiolytic mechanisms, GABAergic modulation, and stress response pathways. Epithalon, a synthetic tetrapeptide derived from the pineal gland, is researched for its effects on telomerase activation and circadian rhythm regulation.

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical cellular coenzyme studied for mitochondrial function, DNA repair, and aging biology. DSIP (Delta Sleep-Inducing Peptide) is investigated for sleep cycle regulation and stress adaptation mechanisms.

All compounds are lyophilised, research-grade, and dispatched fast from Byron Bay, NSW. For in vitro laboratory research use only — not for human consumption or therapeutic application.
