Terms of Use
Last updated September 7, 2026.
Educational use only
Educational use only. This database summarizes published research. It is not medical advice and contains no dosing protocols or recommendations for personal use. Nothing on this site is medical advice, a diagnosis, a treatment recommendation or a dosing recommendation. The calculator and tracker do arithmetic on numbers you enter and keep records you create. They never suggest an amount, a schedule or a compound.
You are responsible
You must be 18 or older to use the tracker or the AI Coach. You are responsible for the decisions you make and for the legality, sourcing, identity, purity and handling of any substance you record. The Longevity Archive does not verify any of those things and makes no representation that any compound is legal, safe or appropriate for you. Talk to a licensed healthcare professional before acting on anything you read here.
Accuracy
We cite published research and review profiles on the dates shown, but research changes and errors are possible. Calculator results depend entirely on the numbers you enter; check them against your label and your syringe. Level charts are simple illustrative models, not measurements.
Your data
Tracker data is stored on your device and is yours. Keep a backup; we cannot recover data you lose by clearing your browser. See the Privacy Policy for details.
Limitation of liability
The site is provided as is. To the fullest extent permitted by law, The Longevity Archive and its operators are not liable for any loss or harm arising from use of the site, the calculator, the tracker or the AI Coach. Where liability cannot be excluded, it is limited to one hundred US dollars.
Acceptable use
Do not use the site to facilitate the illegal purchase, sale or distribution of any substance, to scrape or overload the service, or to attack other users. We may limit or block access to protect the service.
