About

About Light Years

Light Years is a calm companion for people taking GLP-1 medications. It has three parts: a tracker that keeps your weight trend, doses and supply on your own device; a small library of sourced guides; and a cost worksheet for the quotes you get from your pharmacy.

Who makes it

Light Years is built and run by Joshua Nichvolodoff, who also writes and edits the guides. You can reach a real person at hello@lightyears.health.

How it is paid for

For now, it isn't: everything on Light Years is free, and there is no paid plan. Light Years currently runs no ads and no affiliate links. If that ever changes, it will happen only on public reading pages, clearly labelled, under the rules in our advertising policy and affiliate disclosure — never inside the tracker, never next to your own numbers, and never using your health data.

The lines we don't cross

• No medical advice. Light Years never recommends a dose, a medication or a treatment change.
• No claims that you qualify for coverage or that anything improves your chance of approval.
• No invented numbers. Prices and policies are dated and linked to their source.
• Your health data is never sold.

How the guides are made

Read the editorial policy, how clinical review works (and that no clinician has reviewed the guides yet), and how to report a mistake.
