NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells. It is essential for cellular energy production, DNA repair, gene expression regulation, and calcium signaling. NAD+ levels naturally decline with age, and research focuses on restoring levels through supplementation with NAD+ precursors (NMN, NR) or direct IV administration.

Oxytocin is a naturally occurring nonapeptide hormone produced in the hypothalamus. FDA-approved (Pitocin®) for labor induction and postpartum hemorrhage management. Research also explores its roles in social bonding, trust, anxiety reduction, and various neuropsychiatric conditions.

Selank is a synthetic analog of the naturally occurring immunomodulatory peptide tuftsin, developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. It has been studied for anxiolytic (anti-anxiety), nootropic (cognitive-enhancing), and immunomodulatory properties. It is approved in Russia as a nasal spray for anxiety and neurasthenia.

Semax is a synthetic peptide derived from ACTH (adrenocorticotropic hormone), specifically the fragment ACTH(4-7) with the addition of Pro-Gly-Pro. Developed at the Institute of Molecular Genetics, Russian Academy of Sciences, it has been studied for neuroprotective, nootropic, and neurotrophic properties. It is approved in Russia and Ukraine for stroke, cognitive disorders, and optic nerve diseases.
