I have the past year injected 500mcg/ED. I changed the dosage to 300mcg on days without sun, and 750mcg on beach days. Do you have other experience with this is beneficial and provides an even darker color?
I only dose on days im gonna get sun, and I get dark as fuck. skintype 1.* Obviously you have to do more if you want some hairdarkning too.
If that 36 hour rule or something is true, you could inject in the evening before, and the next day before tanning, and you would get double the dose. If you don't want to inject it all at once before tanning that is.
edit: if its been winter and i want to get tan fast, I do 0,5mg each day, and tan EOD day. But I dont see the point injecting if its more than 2-3 days till you will get sun.
