Do you DD, most of the stuff out there is garbage.   Make sure it is not Hemp oil (cold press same as cooking oil).  Make sure when you purchase it that it comes with a testing certification  (gives you the % of CBD, and the % of Terpenes).   I take an isolate powder in the am before the gym and then take an oil before bed.  I am 50.  I do not get that sore anymore after a rigorous workout, biking and or Hiking.  My background is a chemist, so I started making it just to help myself and wife  and now a couple of years later I have working with some companies as a consultant on the different formulations.  Most peoples first experience with CBD oil is not good, because there is some much garbage out there, not much regulation yet.  It is still considered a "nutritional supplement" by the FDA, same classification as vitamins (companies can make any claim).
