On this page
A figure on this site is wrong
Send the page and the figure. Every price here was read off a seller’s own published page, so the most useful thing you can include is what the page says now.
A figure a seller has since changed is not an error — it is a historical reading that needs an update. A figure that was wrong when it was recorded is an error, and it is published on the corrections page, dated and signed.
You sell one of these peptides and want your listing changed
Say which listing and what is wrong with it. A listing is included because the seller prices one of the five molecules this site compares, and it is described in the seller’s own published words. A commission does not change a figure or a description. It changes one order: in the seller cards near the top of a page, a partner that sells that page’s molecules comes first, labeled under its button. What payment does and does not buy is set out on the how we are paid page.
Commercial inquiries
Terms, what is available and what is refused are on the advertise page. Read it first; it answers most of what a first email asks.
Medical questions
These cannot be answered here. Nothing on this site is medical advice — the medical disclaimer puts that in full — and whether a peptide is appropriate for you is a question for a licensed clinician who knows your history.
