Flexall® pain relieving gels are invaluable in athletic training facilities. Since 1987, Flexall gels have proven beneficial in treating athletes worldwide by augmenting ultrasound, cryotherapy, T.E.N.S. and massage therapies. A clinical study verified a 25:75 Flexall / ultrasound gel mixture delivered a soothing sensation of warmth plus deep-heating results equal to 100% ultrasound coupling gel. Flexall (7% menthol) and Maximum Strength Flexall (16% menthol) are unique aloe vera gel formulas that provide penetrating relief from painful muscles and joints due to arthritis, backache, muscle strains, sprains, bruises, and cramps. Flexall gels absorb quickly and completely, are greaseless, non-staining, and gentle on the skin.
