## Questions & Answers

**Q: Approximately how far would be the expiration date?**
A: When I received my last order  I  always look at the expiration date, but I  took them all out of the boxes  to store...   BUT  every  time I have ordered them  (I get 6 bottles at a time)  they are always  way out on the date.    You are to take 2 in AM  and 2 in PM  (I had my Doctor  look at them  ...  he said there is nothing in them that will hurt you,  and to take for 30 days and if they work, continue  taking,   and if they don't work in 30 days  quit taking them.     They are the only thing  that has  stopped by  hip pain ...   I've had shots and other kinds of meds...   and  Arthri-Flex  is the only thing  that has worked for me ....   (I've never had any problems with the expiration date)     Good Luck  and hope they work for you.

**Q: This good for Inflammation?**
A: The BEST JOINT RELIEF  I have ever found.  My Doctor told me to take 2 in the AM and 2 before bed.  Said nothing  in them that would hurt me...  said to take them  for 30 days  if they don't help  quit  taking  and if they do help   keep  taking.     AMAZING   PRODUCT.    I had  tried  all kinds of things  to stop my hip joint pain  and  Arthi-Flex   does it....    I had  taken them  for about 2 years  and thought  I'd  try  to go without them for awhile...   IT WORKED...   and  when  I  did something to  aggravate my  hip  ..  I'd just start them again.....     really  works    ....      when the doctor  said to  try  for  30  days  ....  i  felt  the  relief  in about  7 days....    some people  it takes  more ....    GIVE IT A TRY,   YOU  WON'T  BE SORRY.

**Q: When is the expiry date?**
A: Usually 18 months to 2 years.
