IMPORTANT Stack is a tracking and educational tool for adults 18+. It does not provide medical advice, diagnosis, or treatment, and does not sell or source any compound. Anything you choose to track, you obtain and use at your own risk — always consult a licensed physician before starting, changing, or stopping any protocol.

Vial is a clean, private logbook for tracking what you record yourself — items, amounts, times, injection sites and cycles. It's built for people who want a fast, beautiful way to keep their own administration, without the clutter. Vial is a personal log. It gives no medical advice, no dosing recommendations and no information about substances. You only record what you enter yourself. WHAT YOU CAN DO • Log in seconds — name, amount, unit, time, site and an optional note • Organise your items with your own colour-coding • Track cycles with day-by-day progress • Set gentle reminders so you don't forget • Look back over a clear history and timeline • Private by design — everything stays on your device. No account, no cloud. • Available in English, Dutch and German Vial is a logbook, not a medical device. Always consult a doctor for medical decisions.
