Skull Smash® products are veteran-owned, quality ammonia inhalants that are used by many strength athletes to boost intensity and focus before big lifts.

There are four labels, each with the same time-tested, popular ammonia formula: Skull Smash, Badass Bitch, Brain Grenade, and Deringer. The label design and sizes are for customer preference.

Skull Smash products are designed and made by Steve Welch, a veteran, gym owner, career coach, trainer, and long-time powerlifter and strength athlete. Skull Smash is 100% American-made.
