Changelog
You'll find every shipped change to the calculators, the log and this site here, each with a date. The peptide calculator changelog lists real changes only, so you can see when a formula or screen changed.
Latest changes
Entries cover formulas, screens, accessibility fixes, tests and corrections. Each entry has a date, and math changes also show the engine version. Nothing appears here unless it shipped.

How entries are written
Each entry is one plain sentence, and corrections are marked as Correction. If a change was reverted before release, you won't see an entry here.
For page and screen details, see the accessibility statement.
Read this first. Math based on your entries. This page describes arithmetic on the numbers you type. It does not recommend an amount, a schedule or a product. Check every result against your label and talk to your prescriber or pharmacist. 18+.
