They are both used for tanning, but MT2 has a 'side effect' of producing erections.
I am using it now, been 6 days and am starting to notice a difference, needs to be used in conjuction with some sun or tanning beds for best results.
I am very fair, and do not tan well, those with darker skin may not see a big increase with it.
I am taking 2mg per day, split AM/PM, the nausia was not nice for the 1st 3 days, but not a major concern. No nausia after shots now at all.
My schedual is 2mg per day for 10 days, then 1mg per day for 10 days.
I shall post when I finish if anyone is interested?
