I'm hoping there is one cuz I have no idea how to combo the right items to make stuff as there are tons of items on here :P Thanks! :D

It's not on the forums here, but on Subetalodge you can look for "Genetech lab combination" in the notes, and then you get a (I assume) full list here.
Someone's starting a list of formulas for the new jars here if you're looking for those.
There's also a list here which shows the completed versions, click to find out the combinations to make it.
