— About this compound
Nicotinamide Adenine Dinucleotide (NAD+) is a pyridine nucleotide coenzyme present in every living cell. It is not a peptide and does not fit the strict “research peptide” category — it is stocked because the cellular-pathway literature on NAD+ is deep, the reorder pattern is consistent, and many of the researchers buying Merit peptides also work with NAD+.
NAD+ functions both as a redox cofactor and as a substrate for an expanding family of NAD-consuming enzymes including the sirtuins (SIRT1-7), poly(ADP-ribose) polymerases (PARPs), and CD38.
— Mechanism
Redox cofactor in catabolic and biosynthetic pathways (NAD+/NADH cycling). Substrate for sirtuin deacetylase activity. Substrate for PARP-mediated DNA damage signaling. Central to mitochondrial electron-transport-chain function.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
