Why not open up both routes , one for public funding (this group, reddit, etc enthusiast) who might donate 10-20$ each, and one for those who wants to trial on themselves and have the money to cover the whole trail cost with Dr.B even if it’s 10-15k. They will pay this amount if they did a normal Ht in the US with a reputable surgeon, so why not pay the same in a lower rate/cost country with a donor regenerative potential.
