My knees and legs were hurting really bad I did OsteoStrong twice and I feel so much stronger, energized and the best part my pain in disappearing! I can’t wait to see my OS results in 2−3months to be all set for the SKI season. For anyone with aches and pain at any age OSTEOSTRONG is the best and least expensive option with no drugs or vigorous exercise needed. LOVEIT !! Btw I’m 32(female)
