I, i'm skin type 1 and i use more than 60mg of mt 1 without effect so i switch to mt2. I now use 7mg of mt2 and i don't see any effect. Today i go to sun and got sunburned. I have new moles and great effect on libido so i think it's a good quality of product but no tan. Is it normal ? Is it my skin who can't tan at all or do i have to wait more?
