Hi all. I've been mixing some ejuice. Using VG as base 3.6% VG nicotine then my flavor concentrates. Been using mostly custard and creams added to fruit flavors. I have steeped my juice for about 2 weeks and let it breath for about 6 hrs. I'm finding my flavors very dull and muted. I have added some sweetener to them as we'll but it hasn't made an impact. Any help on how I can get my flavors to punch more. Current flavor ratio is 20%. I have uped it to 30% , but alas still not getting that flavor I'm looking for.. Thanks for the help in advance
