Blood Specimen (Reversible)

Blood Reports Room (Level 1 door inside the Blood Lab): small medical trolley to the north-east, with the Victor's Journal Entry file and Empty Injector #1.

Steroids and Stabilizer recipes (Empty Injector + Infected Blood).

4-step puzzle: the bottom-left corner cube, the middle cube, the top-right cube and the second cube from the top (Game8). The recipes cost 110 blood or more: without the Override Manual (capacity 150) you can't craft them. It is in the collectibles list.
