Why this pen
NAD+ in solution is sensitive to pH, temperature and light. Supplying it pre-mixed in a sealed, cold-chain cartridge removes the reconstitution step in which a redox cofactor is most easily degraded, and the pen's fixed click volume removes handling variability from the measurement.

Cold chain
How we ship it
Every pre-filled pen leaves us cold and arrives in a plain box. Refrigerate on arrival at 2 to 8 °C.
Chilled
Frozen gel packs inside a sealed foil pouch hold temperature for roughly seven days in transit.
Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.
Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Tracked delivery

What is in the NAD+ Precision Pen
NAD+ is the market shorthand for nicotinamide adenine dinucleotide, a dinucleotide built from adenosine monophosphate and nicotinamide mononucleotide joined through their phosphate groups. It is not a peptide. It is a coenzyme found in every living cell, and the reason it appears in a research peptide catalogue is that the same laboratories that study peptide signalling also study the redox and enzyme pathways NAD+ sits at the centre of.
The Celyfe pen holds 500mg of NAD+ in 3ml of solution, giving a supplied concentration of 166.7mg/ml. The vehicle also contains a phosphatidylcholine complex and trans-resveratrol at microgram levels; both are listed on the label. The batch certificate reports the NAD+ result.
Pre-mixed NAD+ versus lyophilised NAD+
Most NAD+ sold for research ships as a freeze-dried powder. Powder is stable on the shelf but has to be reconstituted, and NAD+ in solution degrades quickly at the wrong pH or temperature, so the moment of reconstitution is where the largest error is usually introduced. Our pen ships already in solution, buffered and sealed, and travels cold. The trade-off is that it must be refrigerated on arrival and never frozen.
Quality: HPLC purity and the Certificate of Analysis
Each batch is tested by high-performance liquid chromatography. The purity printed on the batch certificate is the value recorded by the laboratory for that batch, not a generic figure. The certificate names the compound, the batch identifier, the analytical method, the measured purity and the test date. Read it before you order; the current one is linked on this page.
Buying NAD+ in the UK: what to check
- Mass per cartridge and the concentration it implies, not just a headline number.
- A batch-specific Certificate of Analysis that names the batch and the analytical method, viewable before you order.
- Format. Powder needs bacteriostatic water and a reconstitution step; a pre-mixed pen needs cold-chain delivery and a refrigerator.
- What is in the box. The Celyfe pen is the device and the cartridge together, not a bare vial.
- Legal status. NAD+ is lawful to buy and possess in the UK for laboratory research. It is supplied and labelled for in-vitro research use only.
NAD+ Pen: research FAQs
No. NAD+ is a dinucleotide coenzyme, not a chain of amino acids. It is listed alongside our peptide pens because the same research groups study both, and because the pen format suits a compound that is sensitive in solution.
