You know thinking about fading, the only flavors that I have that do not fade are from Flavor West. Single flavors like, juicy fruit, spearmint, bubble gum, skittles. In fact, they grow stronger with time if allowed to continue(storage). So does their Peanut Butter. When I first started DIY there wasn't a lot of flavorings available to the public so I just started with simple basic recipes. At least I had something to
vape that I liked well enough. Using FW's standard suggested starting %(around 15%) seemed a bit high to me but allowed me to
vape almost immediately. As time went on these flavorings kept getting stronger. So much so that I had to split in half to be able to continue to vape them. It happened around the time I was lowering my nic strength so it worked out well for me. Interesting that the new flavorings can be vaped with little steep time but seem to fade. I guess making large bottles(250+) with new flavors may not be such a good idea unless you are ok with boosting the flavor say in a 30ml bottle when transferring. Just thinking out loud....lol
