A Neufit is similar. The trouble is that you can't use it by yourself

It’s very expensive ($50000) with no guarantee it will work.
PONS therapy looks promising but again very expensive.

NOBODY has ever been cured as a result of stem cell therapy, many have lost 10's of thousands of dollars in desperation, many so called medical professionals have got 10's of thousands of dollars richer exploiting desperate people.
That's about all you need to know, forget about it, there's absolutely nothing in it.
It's not new, they've been regurgitating this kind of stuff for 25+ years now to give each new generation of MSers false hope.

From what I understand it’s still very experimental. I’m hopeful that they can make it safe.

No but am interested.
