NAD+

NAD+, also published as Nicotinamide adenine dinucleotide, is catalogued here as: Coenzyme (not a peptide), redox and energy-metabolism research. NAD+ is nicotinamide adenine dinucleotide, a coenzyme rather than a peptide. Cellular redox chemistry is not evidence of improved energy from a purchased vial. A coenzyme, not a peptide, that helps transfer electrons in the chemical reactions behind cellular metabolism.

A reviewed evidence summary for NAD+ is still in progress, so this page does not summarize study findings yet.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people. The reconstitution calculator converts vial content and diluent volume into concentration for laboratory preparation.

Proof Line Peptides lists NAD+ as a vial in 1000 mg and 500 mg, with pack sizes of 1, 3, 5 and 10. Prices are shown in Canadian dollars, and orders ship from Toronto by tracked Canadian service.

The matched PPB Analytical Inc. report for NAD+ 1000 mg (report 2026030610-02, dated Mar. 27, 2026) records 100.00% purity. It documents the supplier sample sent for testing, not every shipped lot, and the original PDF is linked on this page.

Shipped lyophilized (freeze-dried) and stable at room temperature in transit. Store sealed vials in the fridge or freezer on arrival. Once reconstituted, refrigerate. Anything not right? Our guarantee covers it.

Each Proof Line Peptides listing shows the catalogue name, strength, format and CAD price, and links lab documentation only when it matches the exact compound and strength. The lab reports index lists every report currently on file.

Why order from Proof Line Peptides: lab reports are published for matched compounds and strengths, prices are in Canadian dollars, orders paid Monday to Friday normally ship the next business day from Toronto with free shipping from $250, and every order arrives right or we make it right.
