Different from regular strength?
I used this tincture when I lived in the Philippines for several years and ALWAYS loved it!  Never had seen the "extra strength" at the sari-sari store in the remote province I lived in so when I seen it here on Amazon I bought it immediately! (quite shocked at the price because it is less than 10% of this price in PI).  Received it pretty quick and tried it but seem to get same relief from regular strength I have been using for years.  I don't notice it to smell or feel any different also.  Unsure at this point as I am only 1/2 way through 1 bottle.  Will update if I see an pain relief improvement.
