Is Melanotan 1 Safe?

There have been no long-term clinical trials and the side effects of this chemical are unknown. If it could potentially darken or otherwise change moles it could be dangerous. Reactions to the drug vary from person to person ranging from acute allergic reactions, to dizziness, sickness and acne. Since its only available on the internet, probably from sources outside the USA, there is no way of knowing what is actually in the bottle or how it will react to other medicines.  I would not recommend injecting this into your body.

Hi Melanotan or afamelanotide or the commercial name Scenesse is FDA approved for the treatment of Vitiligo in the form of a pellet therapy.  
It can create a tan on 100% of your body.  It has been approved in Europe for 5 years.
Would have to be off label use fro general tanning 
Some compounding pharmacies are compounding the injectable under FDA supervision.
So it is available  
Hope that helps
