Ownership
We're telling you this up front because it's material. A calculator site run by people in the industry it serves could be tempted to steer readers. Our rules below exist to make that impossible on this site.
Independence rules
- No seller links. No page links to a place to buy a compound.
- No rankings, scores or ratings of vendors or products.
- No sponsored content. Nobody pays to appear on or influence a page.
- The arithmetic is neutral. Calculators work the same for any vial from any source, and vial sizes are aggregated from many catalogs without naming them.
Partner links
Peptide Vial Math has no partners today, so no partner boxes appear anywhere. If that changes, every partner link will be labeled Partner, marked rel="sponsored", carry a disclosure next to it (commission, or the owner's financial relationship), and be listed on a partners page. Partner links will never change a calculation or rank a vendor.
Affiliate links
Peptide Vial Math currently has no affiliate links. If we ever add them (for example, to general lab supplies), each will be clearly labeled where it appears, this page will be updated first, and they will never be used for peptides or peptide sellers.
Advertising and data
There's no advertising on Peptide Vial Math. Calculations run in your browser; the numbers you type aren't sent to us. A share link contains your inputs in the URL, so anyone you send it to can see them. Your light/dark theme choice is stored only in your browser.
We count visits with Google Analytics 4. It loads on every page but never receives your calculator inputs (only the page address without its query string); the calculator itself runs in your browser.
