Email [email protected]. Include a link to the page that proves the correct fact.

What we act on quickly

• A supplier has closed, changed domain, or been named in a regulator's letter.
• A fact sheet field is wrong and the supplier's own page shows the right value.
• A supplier that sells research peptides and publishes certificates is missing from the table.

What we do not do

We do not change scores on request, remove accurate negative facts, or add suppliers that do not publish any testing. Supplier representatives are welcome to write; say so in the first line.
