Questions, answered.

Three pieces: the reusable Elixir Pen, the protective Case, and the insulated Cooling Bag for temperature-sensitive vials. You can buy each on its own, or together as the kit.

Yes. The Pen is precision-engineered to be kept and reused — a matte finish, beautifully weighted, and simple to handle every day.

The Cooling Bag is insulated to keep temperature-sensitive vials cool away from the fridge — on travel days, commutes and warm afternoons. The exact cold-retention figure is confirmed and printed at launch, not estimated before.

The Case keeps the pen and its companions cushioned, organised and discreet — at home or in a weekend bag. It's embossed with the Elixir mark and built to be kept.

Medical-grade, durable materials chosen to last and to be cleaned easily. Full material and care details are printed with each piece at launch.

No. Elixir sells hardware and accessories only — the pen, the case and the cooling bag. We make no medical claims. Any prescription medicine is obtained separately from an independent, licensed UK clinic.

NAD+ is a prescription-only medicine. It starts with a short eligibility check, reviewed by a licensed UK prescriber who decides whether it's suitable. If it is, a regulated UK pharmacy dispenses it after a consultation. Elixir simply makes the hardware that keeps a supervised routine organised and cool. Read more on the NAD+ programme page.

No — and by law you shouldn't be able to. NAD+ can only be supplied on a licensed prescriber's order through a regulated UK pharmacy after an assessment. Anyone selling an injectable like it over the counter, with no consultation, is not doing it properly.

Adults, 18+, in the UK. Suitability for any medically-supervised programme is always the clinician's decision.

The kit is new for 2026. Join the list and we'll tell you the moment ordering opens and prices are confirmed. UK only, 18+.

Yes. Everything ships in plain, protective packaging, and the Case is designed to keep the pen tidy and private — at home or in a bag.

Every Elixir piece is covered by our 90-day promise. Try it properly — if it isn't right for you, we'll make it right. Full terms are printed at launch.

Wipe the pen with a soft, dry cloth; keep the cooling bag clean and dry between uses. A full care & travel guide comes with the kit and lives in our Journal.
