How to Contact Me
This site is run as a free resource to help people understand their pen and dosage math. There’s no call centre, no chat team, and no guaranteed response time – but if you have feedback about the calculator or a question, you can use the form below.
Before you send a message
- I can’t give personal medical advice. Only your own doctor or prescriber can do that.
- Best-effort replies only. Messages are answered when time allows, not on a fixed schedule.
- Keep it specific. Bug reports, suggestions, and content corrections are the most helpful.
- No urgent issues. If you’re worried about your health or medication, contact your prescriber or local emergency services.
By using this form, you agree that any response is informational only and not medical or legal advice.
