In the last 5 days I've had 25 minutes worth of sunbed I dose 500mcg daily and have NEVER burned at all once in that time. I'm a skin type 1 naturally I'm just wondering will I ever burn while on this stuff? I find it incredible I NEVER burn, it's always a stand up solarium I go in 9 mins at a time or 6 mins it depends how hot it is outside. My colour is coming on but I want faster results so I'm going to be more aggressive and dose 500mcg 2 times a day - when I go to the solarium and a few hours after that I will do it again I'm going to test this once and for all
