I have been taking Performance lab for almost a month - 2 pills a day. I have no complaints, but I have not noticed any difference....

Just didn't do anything for me.

I cannot offer a rating or feedback now. I purchased Flex for my wife (~69 yrs. old) who has osteoarthritis in her knees. She recently received a cortisone shot and wants to wait until its effects are gone before she tries Flex. Any recommendations or comments are appreciated. I sure do hope that this product will provide some relief and restoration of her knee joints. I put in three stars to satisfy the requirement.

I have been getting cortisone shots in my shoulder. They last about 3 months. I have been taking flex for a month and my shoulder pain is not progressing. Too early to be sure but optimistic.

Only been about three weeks and have not noticed really any difference. Maybe takes longer to work. Time to get here was stupidly slow.

After two weeks the main thing I've noticed is much faster recovery from various exertions including resistance training.
