Fentanyl
Fentanyl: Injected through a fentanyl syringe for pain; highest trade value of any liquid at 2000/L. In-game item, not medical advice.
Use, trade-offs and mechanics
Fentanyl is an exceptionally concentrated opioid fluid in the game. The community item entry gives one milliliter injected a reception increase of forty-two, much larger than the low-potency opium reference. That concentration makes a syringe interaction sensitive to volume. The named syringe is a container and delivery route; it does not turn every amount inside it into a single safe dose.
The wiki describes crafting, mini-barrels and fentanyl syringes as sources. It also gives a trade value of two thousand per liter, the highest listed liquid value in that entry. Its trading note separately caps the credited liquid value of a container at fifty, so a large filled container does not necessarily earn the simple full-volume multiplication. That distinction matters when deciding whether to keep it as stock, a crafting quality source or trade goods.
Opioid quality connects fentanyl to recipes including bruise kits, relief cream, naltrexone and L.R.D. Serum. A powerful liquid is consequently not only a pain-management object. Saving it for crafting or dividing trade quantities follows a different goal from consuming it.
The oral interaction is especially hazardous in the recorded mechanics: drinking one hundred milliliters produces four thousand reception and is described as lethal even with naloxone available. Naloxone is therefore not a guarantee that a mistaken route or volume can be undone. All numbers here describe the fictional item's simulation, not a real medication.
