Are The NAD and Vivere the same company?

No, they're separate UK brands with no connection to each other. Both sell at-home NAD+ injections; the format is what differs, a pre-mixed vial from us against Vivere's 1000mg cartridges.

What's the difference between Vivere's cartridges and The NAD's vial?

Vivere's pen takes reusable 1000mg cartridges. Ours arrives pre-mixed in a single vial and is given with a reusable metal auto-injector rather than a cartridge system.

Does The NAD's testing match Vivere's UKAS-accredited lab?

Both are independently tested, though the labs aren't named the same way. Vivere states its NAD+ is tested in a UKAS-accredited laboratory; ours is tested to ≥99% purity, with the Certificate of Analysis for that batch in the box.

What's in Vivere's kit that isn't in The NAD's?

Vivere's box adds a travel case with a reusable cool pack and a sharps bin. Ours keeps to the vial, the auto-injector, needles and wipes.

Vivere vs The NAD

Comparing Vivere's cartridge pen with The NAD's vial kit.

Vivere makes a UK NAD+ pen that runs on reusable 1000mg cartridges, tested in a UKAS-accredited laboratory. We make the same 1000mg dose differently: a pre-mixed vial, given with a reusable metal auto-injector rather than a cartridge system. Below is how the two kits compare, using only what Vivere publishes on its own site.

The comparison covers delivery and provenance, not effect, and NAD+ is sold in the UK as a food supplement, not a licensed medicine.

Which one fits

Where each kit has the edge.

Vivere may suit you better if
you want a cartridge system you slot into a pen, plus a travel case with a reusable cool pack and free next-day delivery.
The NAD may suit you better if
you'd rather draw from one pre-mixed vial with a reusable metal auto-injector, and want a Certificate of Analysis in the box by default.
