Melanotan II is a synthetic analog of α-MSH promoted for skin tanning and libido. It is not approved by the FDA or, to our knowledge, any major regulator.

What the evidence shows

EVIDENCE GRADE · LIMITED · NOTABLE SAFETY CONCERNS

Melanotan II is unapproved and has been associated in reports with nausea, blood-pressure changes, and effects on moles/melanocytes; regulators in several countries have warned against it. Its FDA review is scheduled for the separate meeting before the end of February 2027.

Is it legal?

Melanotan II is not FDA-approved. In April 2026 it was removed from FDA Category 2 but not moved to the approved Category 1 list, so legal compounding is not authorized; the PCAC reviews it on before end of Feb 2027.

Will Melanotan II become legal in 2026?+

Not automatically. The committee meets before end of Feb 2027; a favorable vote is a recommendation only — the FDA must then issue a final rule, which typically takes months. Realistic legal compounded access is late 2026 to Q1 2027, and only if both steps go through.

Is “research-grade” Melanotan II the same as a medicine?+

No. Material sold “for research use only” is not made or tested to pharmaceutical standards, is not authorized for human use, and carries no guarantee of identity, purity or sterility. This site does not link to or evaluate these sellers.
