The secret to making any decision is to narrow your choices, not expand the search. Expanding the search does not lead you to a decision.
What you do is:
1.) Choose the type of stem cell treatment: cord, human, etc. and the infusion method that you want to have done.
2.) From #1 you will have a list of possible clinics.
3.) Pick possible clinics from #2 and narrow the choices based on cost, location, or other factors important to you.
4.) At that point, you will have one possible clinic, maybe two, and THEN you make your final choice based on what you have read or been told by others.
Keep this in mind when reading ANYTHING negative about ANY company, product or person on the internet:
That it appears on the web DOES NOT make it true!!!!
I shop every day for computer products, and read thousands of reviews about the product, the company, etc. Every product normally receives damning reviews and wonderful reviews. I don't decide to not buy something because I read a few bad reviews or even a few horrible ones. If there are an overwhelming amount of negative comments, then I pay more attention, and try to go with a better rated product.
For example, an internet merchant that I order almost everything I buy from has a lifetime rating of 9.85 out of 10 with 32,460 people voting. Is that good enough for me??? YES, IT IS, without doubt.
When it comes to stem cell clinics, the number of people going is such a small number that statistically, it will be very, very difficult to know who are the bad providers. All you can do is make the best decision you can, pay the money, and take a chance. It is nothing but a chance to begin with, anyhow.
I wish you the very best!
