I can not find any information about the clinic in Ukraine, no witness, a lot of criticism on the internet.Are you able to find out if any of these clinics have other patients you could speak with? Have any of them done any studies or follow up on patients? It's not a good idea to just blindly accept their word that the treatment will help you and is safe. Start doing some research into these clinics and the types of therapy they offer by doing an internet search. There is a risk with these types of stem cells, however, some companies such as Nu-Tech have been using embryonic stem cells for years with apparently no safety issues.
If you are satisfied that the treatments are safe and have the money without going into great debt or causing a hardship on you, then you may want to go ahead with treatment. Also, you should ask questions about the infusions. Are they intranasal, spinal, IV, or what?
