PAVA is a synthetic form of capsaicin, known for its intense heat and irritation properties. Since PAVA is created in the lab, it's efficacy is more consistent than the traditional pepper spray.
PAVA binds to the receptors that send pain and heat signals to the brain, causing targets to experience intense burning on the skin (as if exposed to scalding heat), temporary blindness, difficulty breathing, and extreme discomfort for up to an hour. There are no long term effects.
Projectiles remain potent up to 2 years from their manufacture date. PAVA is widely trusted and used by police, security professionals, and military around the world.
