Here are some more recent findings for those of you who might be interested.

Review

Here is a link to my review of Curranz (contains Anthocyanins), it should have an up-to-date discount code as well. I occasionally get free samples of Curranz which I use for my own sport. I don’t get paid in any way by this company.
