Ammonia Smelling salts for weight lifting have been used for decades in boxing, lifting, and other professional sports.  Smelling Salts are safe and effective if used properly. Smelling salts deliver a high potency of ammonia gas, opening the blood vessels and creating a rush of oxygen to the brain which creates an instance sense of clarity and focus.  

Zone Smelling Salts come in a powder form (ammonium carbonate ((NH4)2CO3H2O)) and is activated by adding 12.5 milliliters of water (about a tablespoon).  When water is mixed with the ammonium carbonate, ammonia gas is released.

Due to its delivery form, Zone last longer than other brands and can be used as needed.  It also prevents the possibility of leaking out in your gym bag. 

Give Zone smelling salts a try and hit that PR.
