The suggestion is to let it steep for 2 to 3 weeks?? I vaped it the day I got the bottle in the mail and its phenomenal! Definitely an all day vape for me. I can see I need to order more than one bottle at a time as I have had it 24 hrs and have vaped 1/4 of the bottle already. MAYBE I'll be able to let the next bottle steep, but I can't see how it can get much better. You will not be disappointed with this juice!
