Has/ is anyone using melanotan?? I am torn between this and spray tan!?

I tan very well but I have recently been getting really paranoid about photo aging so I want to pick a method of sunless tanning. I've been reading up on this melanotan stuff that I recently heard about but I am a little scared to use it.... I have also considered spray tanning at home but I don't know the first thing about spray tanning bc I've never done it and I'm scared I would mess up and look dumb for a week. I also don't want to end up making a mess and getting spray tan all over the place. Does anyone have any suggestions?? Melanotan or spray tanning??
