I've only merely reached out to them and explained them my situation, and asked if there's any hope with their treatment. They believe there is. I'm going there for something other than tinnitus, something that has yet to be classified as an official disorder. I chose to go with StemCells21 based on the reports I've seen on this forum though. 3/4 cases was a success and these people apparently never came back on the forum again once their success story was out. It is supposedely the place to go to. The cheapest you can go infusion-wise is €6000 EUR. I haven't looked further into it than that.Are you currently in contact with them? If yes, what is the information you have been provided with regarding the treatment, price and possible results?
