I’ve had the exact opposite reaction to this product. I bought 2 when introduced to give it a solid try. I just finished the first bottle and have decided to make it part of my supplement regiment. I use a td joint support alongside it and been using this product for months, it works. However, by introducing the joint support xt all soreness in both my knees and elbows has recently gone away in the past week. Even better an injury to my sciatic which left me unable to squat for wayyyyy longer than I was ok with has not returned this past month. This is a solid product and I will be recommending it to anyone who listens haha.I'm sorry to hear that. Overall feedback on it has been great and it has multiple clinically researched ingredients; but different things work differently for different people. I'm surprised with the # of things in it and the different mechanisms of action that you feel it didn't work at all for you though.
