NAD+ vs Vladonix

NAD+ is a coenzyme central to cellular energy metabolism, serving as an electron carrier in glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a required substrate for sirtuins (SIRT1–7) and PARP enzymes, which regulate DNA repair, gene expression, and mitochondrial biogenesis. NAD+ levels decline measurably with age; IV or subcutaneous delivery aims to restore intracellular pools more directly than oral precursors such as NMN or NR.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell, central to energy production, DNA repair, and sirtuin activation. While not a peptide in the traditional sense, it is widely administered by functional medicine and longevity providers via intravenous infusion or subcutaneous injection. Research interest centres on its role in mitochondrial health, cellular resilience, and neurological function as NAD+ levels decline with age. NAD+ IV therapy: intravenous NAD+ infusion is the administration route that has attracted the most clinical interest, particularly in longevity and functional medicine contexts. IV NAD+ therapy delivers the compound directly into the bloodstream, bypassing digestive absorption — a route considered relevant given that oral NAD+ precursors (NMN, NR) have variable bioavailability. NAD+ IV therapy cost typically ranges from $200–$1,000 per session depending on the clinic, infusion volume, and geographic market; treatment frequency in clinical settings commonly ranges from weekly to monthly maintenance infusions following an initial loading protocol. NAD+ IV therapy clinics operate across major US markets including Houston, Los Angeles, New York, and Las Vegas. For those researching where to find NAD+ IV therapy providers, PeptideBase maintains a directory of verified clinics and telehealth platforms offering NAD+ protocols.

Short peptide complex penetrates cell nuclei and modulates gene expression in thymic and T-lymphocyte cells. Promotes T-cell maturation, normalizes CD4/CD8 ratios, and supports cytokine balance.

Vladonix is a Khavinson-class peptide bioregulator derived from thymus tissue, developed as part of Vladimir Khavinson's systematic organ-specific bioregulator research program at the St. Petersburg Institute of Bioregulation and Gerontology, and proposed to restore immune function in aging subjects by modulating gene expression in thymic epithelial cells and thymus-dependent lymphocyte populations. As a thymic tissue-derived bioregulator, Vladonix shares its mechanistic framework with thymalin, the better-characterized Khavinson thymus compound; both are proposed to interact with chromatin regulatory elements in thymic cells to reactivate gene expression programs that decline with immunosenescence, potentially restoring T-cell maturation and peripheral immune competence. Published research from the Khavinson group on thymus-derived short peptides, including thymalin, has demonstrated human hematopoietic stem cell differentiation activity, immune modulation in aged subjects, and class-level evidence for thymic peptide bioregulation, providing biological plausibility for this compound class. Vladonix has no FDA approval and no approved indication in any Western jurisdiction; it is the commercial thymic bioregulator product distinct from thymalin but sharing the same class evidence framework, with no independent published clinical trials specific to this formulation, and its use is confined to the Russian integrative and anti-aging medicine context.
