... All true IDJoel. I would add that I don't know of any source where there is general agreement on the use of MF flavors. Especially compared to what we know with the flavors we already use. There was a handful of folks on reddit who were working with MF but that died off. Some lost patience quickly and dropped out because of the PITA. Open Source Vapor offered open source recipes using MF but they shut down a while back. They were able to figure out how to cut down steep times. Someone archived their recipes on ELR. If you are curious look up user Anonymiss and see the "Open Source Vapor- " recipes. There are 26 or so recipes from OSV there. I did a one off 60ml single flavor test using MF strawberry and thought it was the most realistic of any strawberry. I did not dilute on the recommendation of someone I trust. I tested it after a few days steep and it tasted artificial. A week later it still tasted artificial and the same after two weeks. I found it developed into a realistic strawberry after three weeks. Someone I know doing the same 60ML side-by-side swore their single MF strawberry to be solid after five days. ??? We broke down our 60ml bottles into smaller bottles with the intent of developing something decent. We tried mixing with known flavors and both found we had no patience for it. MF to me means serious time and commitment. Learned a lot but in the end said no thanks. PITA. I would never recommend MF flavors for DIY when there are so many wonderful flavors by the flavor companies we all use. You cannot think of MF in the same sense as TPA, CAP, FA etc. You would need to devote a lot of time in order to develop something decent. To my knowledge Virgin Vapor is the only retail juice company using MF. VV does this for a living. The PITA reputation is very real. I ended up using my MF strawberry to flavor drinking water.
