It's random drop from foes that drop basic mutagens. However farming it is pointless as such foes also drop Madness Mutagen which gives the same effect and more. '''Madness Mutagen = Vitality Mutagen + Strength Mutagen + Concentration Mutagen. '''So there is no point in using these unless you just use what you get or don't want the other effects for extra difficulty.
