Steeping time for milk and doughnut flavours?

[MentholMan]

Hey guys

I've been mixing for over a year but mostly mix menthol fruit combos which are normally shake and vape.

I've mixed a load of cereals too which I find usually take a good three weeks or so to fully develop.

I've recently bought a load of flavourings to mix milky and doughnut flavours but have no idea how long these usually take to steep. I'm assuming they'll take around the same amount of time as my milky cereals (two to three weeks) but could do with some advice from someone more knowledgeable in these flavourings than myself.

Cheers

Milks creams and custard is usually 4-6 week steep buddy and I find donut 3-4 weeks
