Short answer
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and not a peptide. It carries electrons in cellular redox reactions.
It also appears in the literature as nadide, NAD, beta-NAD, coenzyme I, diphosphopyridine nucleotide.

| STRENGTH | FORM | PRICE | CERTIFICATE |

What has research on NAD+ examined?
NAD+ is not a peptide; it is a coenzyme present in all living cells. Reviews cover NAD+ metabolism in ageing, based mainly on animal studies, and human trials have mostly tested oral precursors such as nicotinamide riboside. Human data on intravenous NAD+ are limited to small pilot and observational studies.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
What adverse events have studies of NAD+ reported?
In a retrospective review of clients at a commercial clinic, 500 mg IV NAD+ infusions were associated with moderate to severe gastrointestinal symptoms, increased heart rate and chest pressure during infusion (PMID 41704678). A 2026 review lists nausea, cramping, flushing and chest discomfort, and notes that long-term safety data are lacking (PMID 42787547).
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store NAD+?
Store the sealed vial frozen (about -20 degrees Celsius), dry and away from light until it is reconstituted.
After reconstitution with a sterile solvent, keep the solution at 2 to 8 degrees Celsius and avoid repeated freezing and thawing. Record the solvent, volume and date on the vial label.
BAC Water is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. The reconstitution guide and storage guide cover laboratory handling.
| STATE | TEMPERATURE | NOTES |
|---|---|---|
| Sealed vial | -20 °C | Dry and dark. Keeps to the label date. |
| Reconstituted | 2 to 8 °C | Sterile technique. Avoid repeat freeze and thaw. |
| In transit | Cold pack | Refrigerate or freeze on arrival. |
Is NAD+ legal to buy in Australia?
NAD+ is not named in the Poisons Standard (June 2026 instrument). Source: the June 2026 Poisons Standard instrument (F2026L00633).
NAD+ is not named on WADA's 2026 Prohibited List. WADA method M2.2 separately prohibits intravenous infusions or injections of more than 100 mL in 12 hours outside hospital settings.

Is NAD just vitamin B3?
No. NAD+ is a dinucleotide coenzyme with the formula C21H27N7O14P2. Cells make it from precursors that include nicotinamide and nicotinic acid, the two forms of vitamin B3.
Is NAD+ a peptide?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and not a peptide. It carries electrons in cellular redox reactions.
Is NAD+ a prescription medicine in Australia?
NAD+ is not named in the Poisons Standard (June 2026 instrument). Peptides Collective sells it for laboratory research use only.
Is NAD+ banned in sport?
NAD+ is not named on WADA's 2026 Prohibited List. WADA method M2.2 separately prohibits intravenous infusions or injections of more than 100 mL in 12 hours outside hospital settings.
What is the CAS number for NAD+?
The CAS number for NAD+ is 53-84-9. Its PubChem CID is 5892.
How long does an unopened NAD+ vial keep?
A sealed vial of lyophilised powder keeps to the date on its label when stored frozen, dry and dark. Once reconstituted, keep the solution at 2 to 8 degrees Celsius and record the date on the label.
Does every NAD+ batch have a certificate?
Yes. Every NAD+ batch is tested by [lab] before it goes on sale, and the certificate is published under the batch number printed on the vial. The current batch certificate is [pending].
Where is NAD+ shipped from?
Orders ship tracked from Western Australia. Orders placed before [cut-off] leave the same business day. Delivery estimates by state are on the shipping page.
What purity is the current NAD+ batch?
The current NAD+ batch certificate is [pending]. When it is published, it reports purity by HPLC to three decimal places and confirms identity by mass spectrometry.
Which solvent reconstitutes NAD+?
BAC Water (sterile water with 0.9% benzyl alcohol) is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. Record the solvent, volume and resulting concentration on the vial label.
