No, and for this reason - if it's a new flavor, I learned early on to get the smallest bottle possible, 8-10ml. Then if I liked it or used a lot of it, I'd go for bigger. I never understood new DIYers and the posts that read "Okay, I have my flavors in, tell me what to make....", and post pics of 16oz of each flavor. That's a lotta money for something you're not only clueless how to use, but don't even know if you'll like it. These are usually followed by a second post complaining that their juices all taste bad, and ultimately the third post trying to sell said flavors in the trading post here. (I've cashed in on a few of those...
