Hey,
I've been using melanotan as a redhead, but you can find many other patents online to darken hair and skin without having to use the needles ( no dyes or sunless stains but really increasing melanin activity), what I'm currently looking for is a doctor, formulator, scientist,...that could help me on formulating those patents, calling the right people to see what kinda penetration agents they need,....
So I thought on a scientific forum might be people that could help me and all other users wanting to darken hair and skin.
If you want to have some links, just contact me...
