In the meantime, here's the website for the oral formula I take. And I understand there is always some sujectivity to these things. But I do know I was limping, walking with pain, and knees sounded like shotguns! Whether it's the FlexEasy or some of the other ingredient I'm taking, I can't conclusively say. My only complaint to him was the carbs - about 9 per dosage. You can check the ingredients on the website as obviously I didn't remember them all.
I'm on the auto plan which runs about $26 per month which includes Prioity Mail shipping.
