DOUBLE BARREL, by Skull Smash® is one of the biggest baddest ammonia inhalants on the planet!! This monster sized bottle contains approximately TWICE as much ammonia as our very big large-sized bottles. Besides its massive size, DOUBLE BARREL is essentially three products in one.

You can use the smaller of the two compartments by itself, which can be scented, or unscented, you can use the larger compartment by itself, which can be scented or unscented, or you can get very intense and use both barrels at the same time!! Now, here is where this product gets really awesome…use both barrels, and “pull the trigger” by squeezing the bottle, and hang on for a jolt of intensity that will surely get you fired up to attack some big lifts!!
