Write a compounding worksheet and record that reproduces the preparation exactly and survives inspection — formula, calculations shown, components with lot numbers, in-process checks, and the beyond-use date with its basis. Use when asked to document a compounded preparation, write a master formulation record, create a compounding worksheet, or prepare compounding documentation for inspection. Produces the master formula, the batch record, the component and lot table, in-process checks, labelling, and the beyond-use-date rationale. Documentation only; standards and stability data must come from current official references.

What to give it
▸The preparation — final product, strength, dosage form, and total quantity
▸The formula — ingredients and amounts, and the source of the formula
▸The components — actual products used, with lot numbers and expiry dates
▸Equipment and environment — what was used and where, including any controlled environment
▸The standards you work to — your jurisdiction's compounding standard and the reference used for beyond-use dating
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓Master formula and batch record are separate documents
✓Every calculation is written out, not just its result
✓Independent verification is recorded where the standard requires it
✓Every component has a lot number and expiry
✓In-process checks were recorded at the time, with the checker named
✓Actual yield is compared against theoretical, and any discrepancy is investigated
✓The beyond-use date cites the specific basis it derives from
⚠️ What it refuses to do
**A result with no working.** Uncheckable, and the first thing an inspector asks to see.
**Components without lot numbers.** Makes a recall impossible and is a serious finding.
**A beyond-use date by habit.** '30 days' with no cited basis is written up every time.
**Reconstructing in-process checks afterwards.** A check recorded later is not a check.
**One document for formula and batch.** The recipe becomes unreproducible once it is entangled with a single day's numbers.
