What does the evidence say about Melanotan II?

Animal & lab studies only

Small early studies and case reports do not establish a safe consumer product.

What are the risks and side effects of Melanotan II?

  • Not approved for human use. Products sold online as "research chemicals" are not made to drug standards, so identity, purity, sterility and dose are unverified.
  • Case reports describe new or changing moles and uneven pigmentation.
  • Nausea, flushing, spontaneous erections and blood-pressure effects can occur.
  • Nasal and injectable online products may be contaminated or mislabeled.

What should you ask a clinician about Melanotan II?

  • Should changing pigmentation or a mole be examined?
  • What proven sun-protection or sexual-health options fit my concern?
