I definitely know where that protein recipe is. I didn't think it was a recipe, so much as just lore.
The Mainframe PC is what I can't access anymore, but I did hit it before I got transformed, so maybe if I get the protein recipe it'll help.
The Site Zeta is the one you reach going from the arc trees, to the purple tree, right?
I know there's some data at the computer but they want a level 3 or 4 key, which I don't know how to get from the lab to the forest.
The Orange one is upwards from the forest hut stand on top of it (very important)from there follow the Page direction and stand on top of the red one after following the the diary directions again you will be teleported after set distance ( its a trial of error there are no slimes along the path so its safe to try)
Note: there are 2 red tree one bring you to the Void forest(following real life magnetic direction) the Other to the Painted forest(following Looped Forest magnetic directions)
