# Expectations Desk > There are no promised timelines here. This page offers a sensible way to try a supplement, note changes and decide when to stop. ## Guides - [Set an End Date Before You Start](https://reasonable-trial-expectations.pages.dev/set-trial-end-date/): Pick a finish date before the first dose and write it down, because a trial with no end tends to run on out of habit rather than evidence. - [What Counts as a Real Change in Your Mouth](https://reasonable-trial-expectations.pages.dev/what-counts-as-a-change/): A real change is one that is noticeable, repeated over time and still there when you account for everything else you altered. - [A Baseline Checkup Before Your Trial](https://reasonable-trial-expectations.pages.dev/baseline-dental-checkup/): Book a baseline dental checkup before you take the first dose, so you have a professional record to compare with later. - [Deciding to Continue or Stop](https://reasonable-trial-expectations.pages.dev/decide-to-continue-or-stop/): At the end of a trial, look at your notes and your dental follow-up, not at hope or habit, and decide to continue or stop on what you can actually point to. - [A Simple Notebook for a Supplement Trial](https://reasonable-trial-expectations.pages.dev/supplement-trial-notebook/): A supplement trial notebook only needs a few fixed fields, filled in briefly at the same time each day, so that you can look back without relying on memory. ## About - [About Expectations Desk](https://reasonable-trial-expectations.pages.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://reasonable-trial-expectations.pages.dev/feed.xml)
