DOUBLE BARREL, brought to you by Skull Smash, is one of the most potent ammonia inhalants available! This enormous bottle contains roughly double the ammonia of our large-sized bottles. Besides its impressive size, DOUBLE BARREL is effectively three products combined. You can use the smaller of the two compartments on its own, scented or unscented, or the larger compartment independently, scented or unscented, or even both barrels simultaneously for an intense experience! The thrill of this product lies in using both barrels and ‘pulling the trigger’ by squeezing the bottle, readying you for a burst of intensity that will surely motivate you to tackle some heavy lifts!

• Select your scent options in the drop-down menu above.
• The left option of the / is for the large compartment, and the right option of the / is for the smaller compartment.
• We cannot ship Smelling Salts internationally.
