Editorial policy

Our calculators convert numbers readers enter. Some pages also explain information from medicine labels. This policy describes how we check and present that information.

Math only

• Reconstitution calculators convert numbers the reader enters; they do not prescribe a dose, frequency or dilution.
• Vial-size buttons set the amount in the vial only. Water and dose fields always start blank.
• Calculators don't decide how much to take, how to increase a dose, or how to prepare, store or obtain a product.
• Schedule pages describe doses and timing in specified product labels. They are educational references, not individualized schedules; the prescriber decides the patient's dose and any changes.
• Worked examples are labelled as arithmetic, and use numbers chosen to show the formula.

Accuracy

• Every formula is defined once and shared by every calculator and table on the site.
• Automated tests check each formula against hand-worked values, round trips (dose to units and back), unit conversions, blend calculations and capacity warnings.
• Every number in a generated table is recalculated by the tests before release. A mismatch blocks the release.
• Results are worked out from the vial amount and volume directly, not from a rounded concentration, so repeating decimals don't add error.
• All syringes on this site are U-100: 100 units = 1 mL. Barrel size (0.3, 0.5 or 1 mL) is capacity, not a different scale, so a smaller barrel is never labelled as if it used different units.

Sources and regulatory status

• Pages list their sources at the bottom, including prescribing information, FDA pages, peer-reviewed papers or clinical trial registries where relevant.
• Each compound's status (approved, investigational or not approved for human use) is stated where it matters and rechecked against current sources.
• Clinical trial information, where it appears, describes what participants received in a supervised study. It's never presented as a schedule for anyone else, and it's published only after the numbers are checked against the trial papers.
• Company press releases and news reports are labelled as such when they're used, and aren't treated as peer-reviewed evidence.

Independence

The site sells nothing, has no affiliate links and accepts no sponsorship from peptide sellers. Pages never link to sellers. If the site ever carries advertising, ads will be kept apart from calculator controls and results.

Corrections

If a number, formula or statement is wrong, please report it to ezra@peptidedosecalculator.org with the page and the details. Calculation errors are prioritized. When we make a substantive correction, we will add a dated note to the affected page explaining what changed, and update its date. Minor spelling and formatting edits do not require a correction note.
