I have used Arthro-7 since I was 30 years old. 
I first heard of chicken collogen from a cassette tape titled "Dead Doctors Don't Lie," and I  had believed what I learned. Shortly after, my mother, noticed my growing knuckles  asked me to  start taking it.  She also had rheumatoid arthritis and was convinced that Arthro-7 worked for her.  She had been relieved from aching fingers and  joints within just a few weeks of taking the starting dose m. I knew well,  that previously,   she could hardly hold a pen in her hand let alone write a letter. But now she coud hold a  pen nd write with letter!  I was not only  impressed, but very thankful that a  friend had introduced her to it. 
So, convinced, that it would prevent any further malformation of my fingers and knuckles,  she introduced me to Arthro-7.  
I'm now 76  yrs old, and my knuckles  have not grown any larger than normal I'm  sold on Arthro-7 and have recommended  it many  family members and friends.  I have been on a maintenance dose for many years. If I feel pain in my joints I take the recommended dose and it's gone in a couple of days.  I know Arthro-7 works very well for me!
In my opinion,  Arthro-7  deserves a 5 🌟  rating.
Please,  don't change it !
