Reporting a correction
If a peptide library figure, description or source link looks wrong, please say which page and which value, and include the source you believe is correct. Corrections are applied to the shared dataset so every page updates together.
Calculation issues
If a calculation looks wrong, include the exact inputs you used (vial amount and unit, liquid volume, target amount and unit, syringe type) and the result you expected. The full arithmetic the site uses is published on the Methodology page, which is usually the fastest way to identify a unit mismatch.
Suggesting supplies
The supplies page includes a built-in suggestion form where you can submit a product and a URL.
