I'm somewhere between a 2 & 3 on the skin type... I started at a low does & gradually worked up to the dose that works for me which is 1ml I usually take it daily...sometimes I miss a dose which is no big deal... I personally find taking it a few hrs before a tanning bed session or in the morning before a beach day works best for me... seriously I get nice and brown from a beach day... also I noticed it works better injecting into my belly rather than just under my skin on my hip... but this stuff really works great...I didn't tell my wife I use it just to see if it really is noticeable..
. Just the other day she told me she's never seen me so tan! 😂😂😂
