so far as i know fruity loops is based on orange and flakes are lemon, capella sl has a good base for fruity loops, now are you going for cereal only? or cereal with milk? if its cereal only you need that dusting of sugar if milk well more milk would be welcomed.

also the tpa version of fruit rings(non milk) is rather strong you might wanna give it a try.

Fruit rings already cover this flavor a bit but I would maybe try up to 1% lemon. It is a flavor kind of punches of the fruit loop flavor for me.

Hi. There‘s a review of Purilum Lemon (now Lemon Sicily) on Reddit. The flavor was tested at 7% and was very faint, not noticeable in mixes. It also fades. If you are looking for a few good lemons, FE (SC) Lemon and INW Lemon Mix are both great and strong. Strawberry Ripe is also known to fade. Have you looked at other fruit loop recipes?

I‘m also pretty sure that FW Fruit Rings contain sugar (corn syrup or fructose), which is not safe to vape.
