How do I report a wrong number?
Email corrections@peptidevialmath.com with the page URL, the inputs you used (vial mg, water mL, amount, syringe) and the result you expected. A share link from the calculator carries the inputs for you. We recompute it with the formulas on the methodology page and, if the site is wrong, fix it and update the page's date.
How do I send a privacy request?
Email privacy@peptidevialmath.com. The privacy policy explains what the site handles: calculations run in your browser and nothing you type is sent to us.

What we cannot answer
We do arithmetic. We can't tell anyone what amount to use, how often, or where to buy anything, and we don't reply to those questions. See the disclaimer.
