Let's just cut straight to the point, you want to be a rampaging junkie and I'm here to give you that hit with the knowledge of how the Syringes work!

Note: I've had odd results ingame and when comparing with the actual data when it comes to the HP Values on Adrenaline so bear that in mind.

Note 2: Keep in mind that the 1 and 2 second(s) Regen Penalty applied by Hard/Extreme Difficulty are applied AFTER the Regen Delay Reduction from Adrenaline.
