DESCRIPTION
A serum that instantly grants the Adrenal Reaction mutation: +5% weapon damage for every kill in a kill streak.
The bonus builds with your kill streak up to 10 stacks, for a maximum of +50% weapon damage. The downside is -50 maximum health, which the Class Freak perk reduces, and the serum itself suppresses the negative effect for an hour after injection. Adrenal Reaction used to boost damage at low health and was a staple of Bloodied builds until it was reworked around June 2025. Its effects are suppressed while Rad-X is active.
One serum is delivered with this order.
