I've been using this for about two years now and first started a little before COVID, I really noticed improvement in my sore pulleys after drinking it for about two weeks. I didn't write an review back then because I wanted a little more testing.
Since my come back from the COVID break, I've been consistently using the supercharged collagen and my pulleys have been all good and strong! And I've been bouldering harder too! Wish there is a way for me to systematically demonstrate the effectiveness of this stuff, but based on my anecdotal experience, it works :) Thanks a ton to coach Hörst for sharing all the training/rehab tips and for creating this magic formula!
