House of Gains Smelling Salts (Skull F*ck) is an ammonium carbonate inhalant used before max-effort lifts for an alertness jolt - ships as a powder activated with a small amount of water, not ready-to-use out of the bag.
Fitness AccessoriesSmelling salts work through simple chemistry: ammonium carbonate releases ammonia gas that irritates the nasal and lung membranes, triggering a reflex that sharpens breathing and alertness for a short window. They're a long-standing fixture in powerlifting and strongman specifically for that pre-lift jolt right before a max attempt, rather than something used throughout a workout. This particular product ships as a powder (to avoid leaking) and needs to be activated with about a capful of water before use. Worth knowing for the shelf: the brand itself flags this as not for beginners, with effects that fade quickly and can be followed by a short energy dip - it's a specialty, occasional-use accessory rather than a daily supplement.
