Flexoplex has done wonders for in eazing pain to my knees. I'm a basketball official for high school While doing 5-6 games per week, flexoplex has allowed me to recover a lot quicker after each game vs before I began using the product. I began feeling a difference about 2-wks after my 1st initial use. I began using flexoplex in August of 2019 with intentions of building myself for the season. It paid off! Now I'm able to train in preparation for the basketball season with little or no pain after a work out. My recovery time is a lot better these days. At age 57,I bike & do hill work in preparing for the season. I tend to train year around. Thank you. Alton Henry
