Has anyone had any success using Glucosamine for knee/joint pain?

I know that overall from what I’ve read regarding medical studies, it seems that Glucosamine Chondroitin either doesn’t work or maybe helps some people a little. Yet, many doctors still recommend it for sufferers of joint pain and osteoarthritis, saying it doesn’t hurt and it MAY help. Additionally, there are just endless reviews online with people saying they believe it really helps them. I’m just wondering if any of you guys have tried it for a good 8-12 weeks and if so, what was your experience?

For reference, I have a relatively minor but still annoying issue with my knees from time to time. I’d say about every other month I will have to stop exercising for 5-7 days because it gets achy and is clearly worsened by HIIT. I stop, let it heal and then have another good while before the familiar ache returns. I think I’m going to give GC a whirl and see if it helps at all. I’d love to hear other’s experiences, whether positive or negative. Thanks guys :)
