I’m 48 years old, very active. I go to the gym 4 times a week, spinning 2 of those days and I play hockey 2 to 3 times a week. I pulled my groin playing hockey 2 Saturdays ago, the next three days it hurt to walk, couldn’t workout or skate. I received the recovery kit on Thursday, used it that night and again on Friday night, went to the driving range Saturday morning and played hockey in the afternoon for 2 hours with just a little pain. I used it again on Saturday night just to be sure, got up Sunday went to the Cape and played golf without any pain. Today I feel great. I just put the last application I have on my 72 year old mothers bad knee. She needs a little convincing. If I had enough of the stuff I would pretty much cover my body to get rid of all my aches and pains. You have a great product.
