i use a weekly pill box set up to taste test new flavors. No reason to make an entire 5ml, or 10ml when just .3, and .2 of that will do for a mix to test vape.
I'd never considered this! I'm constantly rewashing bottles as it is, thanks.
I mix my FlavorArt flavorings at 5% and my TPA flavorings at 10-15% (those are all I have so far, only started DIYing last week). When I'm doing a test batch of, say, one flavor, I'll do like 18 drops of 0 nic pg/vg at the ratio you want, and 2 drops of the flavoring.
Be aware that you'll probably place another order of flavorings pretty soon after the first one shows. My wife's really gotten into DIYing and has whipped up a green tea we both really enjoy. Her tastes in vapes is nothing like she expected, so it's been good to have some options.
