The Clinical Trial is a primary weapon for the medic that was a Weapon of the Day. It is visually identical to the Overdose.

Using the Alt-Fire button will, if possible, remove 80% of the user's Übercharge to grant him crits to all weapons for 4 seconds, and it also deals more critical damage. However, it comes with several downsides including reduced reserve ammo, firing speed, damage done and clip size, increased reload time and switching speed and the lack of random critical hits.
