Buy NAD+ in Canada: A Researcher’s Guide
The first thing to get right about NAD+ is that it is not a peptide at all. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular energy metabolism, and it is studied in that context rather than as a signalling peptide. It is grouped with research peptides because researchers who follow cellular-energy work order it alongside them. For Canadian researchers the practical questions are format, sourcing, and what to verify first.
Two formats: vial and nasal spray
Vistara Labs stocks NAD+ two ways. The NAD+ 500 mg vial (lyophilised) is reconstituted with bacteriostatic water for research handling. The pre-mixed NAD+ nasal spray ships ready to use in a metered atomiser. Both are third-party tested with the purity figure on the product page.
Why researchers source NAD+ domestically
Cross-border orders are routinely held or seized at customs. Both formats ship from within Canada, third-party tested, with e-transfer and credit card accepted, same-day dispatch before 3 PM PST, and free shipping over $150.
What to check before you buy
- Purity documentation on the product page.
- Format, vial reconstituted with bacteriostatic water, or the ready-to-use spray.
- Research-use framing, sold for research only; see our legal overview.
Where it fits
We explain why NAD+ is a coenzyme and not a peptide in NAD+ is not a peptide. It sits within cellular-energy research alongside SS-31 and MOTS-c; the full set is on the Cellular Energy & Mitochondrial Research page. It is also one of the six pre-mixed nasal sprays we carry.
Frequently asked questions
Where can I buy NAD+ in Canada?
From domestic research suppliers. Vistara Labs stocks NAD+ as a 500 mg vial and as a pre-mixed nasal spray, both shipped from within Canada.
Is NAD+ a peptide?
No. NAD+ is a coenzyme, not a peptide, though it is commonly grouped with research peptides.
Is the NAD+ nasal spray pre-mixed?
Yes, it ships ready to use in a metered atomiser, supplied in saline.
Is NAD+ legal in Canada?
It is sold for laboratory research use only. It is not sold for human use, and nothing here is medical advice.
All products discussed are for laboratory research use only and are not for human use. Nothing on this page is medical advice, and no statement about any compound is a claim of therapeutic benefit.
