After viewing this products endorsement on SharkTankI purchased 5 bottles@ 199. In March of 2019 and started using product a few months later and within a couple of days noticed considerable improvement with very uncomfortable leg pain from previous hip replacement surgery. Upon finishing 1st bottle and starting 2nd bottle my leg pain reappeared and I was very disappointed. Then I realized that the contents in the 2nd bottle were a light green color in the eyedropper instead of the much darker color in the 1st bottle and so I opened a 3rd bottle and after shaking as directed noticed that the contents were a darker color and after using noticed lessen'd leg pain again.
I tried contacting Cachet on their 800 number for a couple of days with no luck but was able to finally connect with a third party that was not able to help and was not really interested with my comments.
In short I would not recommend this product.
