About Tan Lines

If you searched for Melanotan II, you probably found two kinds of pages: sites selling unregulated vials, and thin warnings telling you nothing. This site is the third thing — the actual story.

Melanotan II is an unapproved compound with a genuinely remarkable history: born from legitimate melanoma-prevention research, escaped into a global gray market, and ancestor to two FDA-approved medicines that have nothing to do with tanning. We cover that history the way a science journalist would — including the harms, the hype, and the open scientific question underneath it all.

The editorial rules

We do not sell Melanotan II or anything else on this domain. We do not publish sourcing information, dosing guidance, or usage advice for unapproved compounds — not framed as harm reduction, not framed as history. The cautionary tale is the point, and it stays a tale.

Every article is dated, grounded in published research and public records, and honest about uncertainty. When the evidence is thin, the article says so. When popular claims are wrong, the article says that too — including claims made by people selling things.

Where we're openly opinionated

We think the world still needs what the original researchers were chasing: a rigorously tested, approved medicine that gives human skin durable protection from ultraviolet damage, delivered in a form ordinary people would actually use. We call that position what it is — hope, clearly labeled — and we analyze what standing between here and there. Nothing on this site is medical advice.
