Questions (9)

What is Melanotan II?

Melanotan II (Melanotan II (MT-II)). Synthetic non-selective melanocortin receptor agonist. Stimulates melanogenesis (MC1R) producing skin tanning; also has appetite and sexual-function effects via MC4R.

What is Melanotan II used for?

Commonly discussed uses: skin tanning (cosmetic, research), libido (anecdotal). There is both human and animal/preclinical research, though the depth and quality vary by indication. Note: most uses are not approved indications.

How does Melanotan II work?

Mechanism: Synthetic non-selective melanocortin receptor agonist. Stimulates melanogenesis (MC1R) producing skin tanning; also has appetite and sexual-function effects via MC4R.

Is Melanotan II safe?

Reported considerations: nausea, facial flushing, spontaneous erections, darkening of moles/new nevi, concerns re: melanoma surveillance. There is both human and animal/preclinical research, though the depth and quality vary by indication. Subject of explicit safety warnings from TGA/FDA/MHRA, particularly regarding skin cancer/mole monitoring. Not approved anywhere. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of Melanotan II?

Commonly cited ranges (educational reference, not a recommendation): low loading 250mcg/day, typical loading then 500mcg-1mg 2x/week maintenance, high 1mg/day (higher side-effect risk). Administration: subcutaneous. Half-life: ~hours.

Is Melanotan II legal in Australia?

Australian status: Prohibited import without authorisation; not ARTG-registered; TGA-warned product. Subject of explicit safety warnings from TGA/FDA/MHRA, particularly regarding skin cancer/mole monitoring. Not approved anywhere. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.
