Questions about the calculator, a correction to a formula, or a suggestion for a new guide? Send us a message below.

We read messages about calculation errors first — if a formula, table or worked example on this site looks wrong, please include the page name and the numbers you entered so we can reproduce it.

Contact by email

Prefer your own email app? We are moving the site to its own domain, and our contact email address will be published on this page as soon as that move is complete. Until then, the form above is the way to reach us — and please remember it confirms on screen only, without storing or transmitting anything.

What we cannot help with

We cannot advise on doses, protocols, sources or whether any peptide is right for you — those questions belong to a licensed healthcare provider or pharmacist. Messages asking for medical advice will be pointed to the Medical Disclaimer rather than answered individually.
