All UB Consumables work the same way, just having different effects on your Breedable.
You will have to feed any UB Consumable directly to a selected Breedable through the Breedables Menu.

How to feed Consumables:
- Rez the Consumable you want to feed close to the Breedable
- Choose 'Consumables' on the Breedables Menu
- Choose the Consumable

The Consumable will vanish and the effected Stats will change on your Breedable.
