It doesn't surprise me, from them. Last year, I emailed them to get precise informations for someone from my entourage who wanted to go there. I used medical and technical terms, and they never answered. It seemed to me that they use superfluous things.
Well, they seem to prefer dealing with lay, credulous, not forwarned patients, with people who are impressed by their "sophisticated" protocols, "modern", "latest fashion" treatments. Well, it's a swiss clinic, they have to "justify" their high (indecent) prices with "high" technology, "modern" rooms, etc. As always, business!
Something I often notice, whatever the domain, the matter: the simpliest things are often the best ones.
Another point: it's about stem cell. Stem cells become adult cells in order to accomplish their function then die, as all cells. They don't stay in your body all your life. So, you'll pay a huge amount of money for only 1 session (1 stay) in their clinic. Will you be able to undergo the process every month, for example? Maybe it's a question you can ask them.
In all fairness, the fact that you did not get a reply to an involved email is not a surprise considering how busy they are there. I mean, you have to be there to understand that those doctors and nurses are really working hard, constantly. They have clerical people who only have a modest amount of knowledge, but who have a list of protocols etc, to answer emails.
Also, it is only "Swiss" in name - the owners/operators and most of the medical personnel are Russian. They hire nurses and orderlies and lab people from the local environment, and they all must be super good and super professional and speak English. I don't think I've ever been around such good nurses before.
It seems to me that they are trying to make their protocols available to people who have been abused or abandoned by the Western medical system. The prices are high by most EU standards where socialized (and often deficient) medicine is the thing. But compared to prices in the West in general, what you get for your money is a LOT.
On the other hand, you are right about stem cells - they have to become adult cells, and if the problem is protracted, you have to get more of them repeatedly. For that purpose, they freeze a batch of your own cells, and culture them for "refills".
Having said that, what I noticed is that particular conditions are the main focus and some of the mystery diseases and conditions of the West are just not within their purview, I don't think. I'm also not so sure that just loading up on stem cells willy nilly is the right solution; it seems to me that stem cells might need to be "guided" in some way, and they don't appear to be doing that. I'm not sure about that, but I seem to remember something about it.
I learned a LOT from them, and got some really good ideas and guidance in certain things, but after working my way through the fallout, I think there are a few things they could add to their bag of tools, including teaching people/family members of patients, to do AHT on an ongoing basis in order to give support to the stem cells. Another thing would be teaching people about light therapy that can also do a lot to activate and support stem cells.
Another thing, when we asked if Dr. Gaby could accompany us, they were happy to have her and she was allowed to go wherever she liked, to see all the equipment, techniques, etc, as they did their rounds and such. They don't have much in the way of spare time, but they accommodated her as best they could, answered questions "on the job", so to say, and were generally very welcoming.
