Ultra penetrating formula. Fast acting. Greaseless. Effective. Arthritis. Bursitis. Muscle pain. Tendonitis. Maximum pain relief. As a violent storm interrupts the rhythm of life, physical pain jolts the body of its natural energies to perform. The sheer presence of physical pain distracts. Until Thera-Gesic, no vehicle existed that would allow more than minimal penetration. Thera-Gesic is a topically applied analgesic. Its unique penetrating delivery ensures maximum effectiveness against pain. Some say Thera-Gesic works like fire, some say it works like ice. Some feel a tingly sensation. But everyone agrees: Thera-Gesic works. And the persistent sensation of pain is quickly replaced by the feeling of relief. The Thera-Gesic difference is a difference worth feeling.
