What is Melanotan II?
Melanotan I and setmelanotide are different library cards. Setmelanotide is an approved product for rare genetic obesity syndromes. That approval does not move to Melanotan II. Sexual-function and tanning stories are not cited verdicts here.
Research melanocortin receptor agonist.

What the cited papers actually measured
Older papers (including PMID 14578215) describe melanocortin activity and pigment. FDA consumer updates on tanning products and warning letters address unapproved melanotan sales. Reported harms in papers and regulator materials include nausea, darkening of existing moles, and blood-pressure changes. Those reports do not give a frequency. They also do not clear anyone to use the product.
We mark the cited papers as D. That is our label for how strong those papers are. It does not say the compound works.
How long it lasts, how you store it, listed sizes
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
The chart uses the 10 mg listing. Light-sensitive solutions should follow the printed label. That is handling. It does not write a plan.
U-100 math for listed Melanotan II sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 10 mg | 100 | 50 | 33.3 |

Questions people ask
Is Melanotan II legal to sell as a tanning drug?
FDA has warned that unapproved tanning products are not legal drugs. This page is education. It is not a sales or legality opinion for a specific seller.
Does a public figure talking about tanning peptides belong here?
Only if we quote a cited public statement on a separate people page, with no photo and no buy button next to the quote. This compound page does not do that.
