Thanks for the link to the thread jaredwho. Would be interesting to know how long he were on Melanotan-I, it would be expected to have to use it for one or several months for any effect on skin type 1.
I did find a successful use case for Melanotan-I on skin type 1:
Melanotan1 and Melanotan2: Melanotan 1
Dangers: I'm sure sides are bearable. But little is known, scientifically, about long term effects from Melanotan-II, whereas pretty much is known about Melanotan-I from the Scenesse tests. I'm thinking of long-term increased risks of skin cancer etc.
