For Research Use OnlyNAD+
NAD+ is a nucleotide-derived coenzyme central to cellular redox reactions, present in every cell and maintained through synthesis and salvage pathways. Supplied at 250mg for $40 or 500mg for $55 — $0.16 and $0.11 per mg respectively. That it is essential is settled biochemistry; whether administering it raises the pool inside cells, where it would need to rise to matter, is genuinely unresolved, and the two claims are routinely elided. It is not a peptide, so a certificate written in peptide terms indicates a template rather than an analysis. Research use only.
