The supported programme

Exploring NAD+?

Elixir makes the pen, the case and the cooling bag. NAD+ itself is a prescription-only medicine — so it starts with a quick eligibility check, reviewed by a licensed UK prescriber who decides if it's suitable. Never an over-the-counter sale.

Elixir is not a clinic or pharmacy and makes no medical claims. NAD+ is prescription-only and supplied on a licensed prescriber's order through a regulated UK pharmacy after assessment. 18+, UK only.

Peter, founder of Elixir, holding the Elixir pen
Why we built it

The object mattered.

“Routines like this used to live in a plastic pouch at the back of a drawer. We thought the object itself should be worth keeping — engineered properly, discreet, and calm. So we built the pen, the case and the cooling bag we couldn't find.”
Peter · Founder, Elixir

Questions, answered.

See all FAQs →

What's in the Starter Kit?
Three pieces: the reusable Elixir Pen, the protective Case, and the insulated Cooling Bag for temperature-sensitive vials. Buy each on its own, or together as the kit.
Does Elixir supply any medicine?
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.
How long does the Cooling Bag keep vials cool?
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.
Is the Pen reusable?
Yes. The Pen is precision-engineered to be kept and reused — a matte finish, beautifully weighted, and simple to handle every day.
Is delivery discreet?
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.
What's your returns policy?
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.
