NAD+ testing in Canada

NAD+ is not a peptide. It is a dinucleotide, it degrades readily in solution, and the question worth asking about a vial is less what it is than how much of it is still intact.

Not a peptide at all

Nicotinamide adenine dinucleotide — two nucleotides joined through a phosphate bridge. Every cell makes it. Nothing about it is peptide chemistry, and we would rather say so than let the compound sit unexplained among peptides on a price list.

Class
Dinucleotide, not a peptide
Formula
C21H27N7O14P2
Mol. weight
663.4 Da

Nicotinamide adenine dinucleotide

What happens to NAD+ on a shelf

It falls apart

NAD+ hydrolyses to nicotinamide and ADP-ribose, and it does so faster in solution, faster when warm, and faster at the wrong pH. A vial can be genuine on the day it was filled and substantially degraded by the time it reaches you.

That makes measured content the figure that matters, and it makes the result a statement about this vial today rather than about the vendor in general.

The related compounds

NMN and NR are sold into the same market and are different molecules at different masses. So is NADH, the reduced form, two daltons away from NAD+. All four are distinguishable by mass; none are distinguishable by looking.

Ask us before ordering

Because NAD+ is not a peptide, the method differs from our standard panel. If you are considering this test, write to us first and we will confirm scope and turnaround before you pay.

What your certificate reports

  1. Identity — confirmed from precursor-to-product-ion transitions on a triple quadrupole instrument, not inferred from retention time.
  2. Purity — measured at the quantifying transition, with the method named on the report.
  3. Net peptide content — quantified against an external calibration curve and reported as its own figure, in milligrams. Why this is a different number from purity.
  4. Peak data — the chromatographic results behind each figure, printed on the certificate rather than held back.

Common questions

How much sample do you need?

One unopened vial. Detailed posting instructions arrive with your order confirmation, immediately after you pay.

Does it need to be shipped cold?

No. Lyophilised peptides travel safely at room temperature, which is how nearly all samples reach us.

Who actually performs the analysis?

An independent Ontario laboratory. Every certificate we issue names the facility that ran it — we are a testing service, not a laboratory, and we would rather say so than let you find out from the report.

What if the result comes back bad?

You get the result. We do not soften findings, and we do not charge differently depending on what the analysis shows.

Can I verify the certificate is genuine?

Yes. Every certificate carries an identifier that anyone can check against our records, including the vendor you bought from.
