You can. The restriction is on anyone else offering it to you. Theres a long tradition of medical researchers experimenting on themselves. Barry Marshall was so sure bacteria could cause ulcers that he consumed said bacteria, and gave himself ulcers in order to cure them with antibiotics. There’s also a FDA provision for treatment of last resort. If you’ve got a terminal condition with no approved treatment and there’s a possible treatment of unknown safety and effectiveness you can apply and get that treatment. If you or a loved one has Alzheimer’s I highly encourage you to request this treatment. You’ll be risking unknown side effects and or death, but it will generate data for those who come after and could advance the treatment of this terrible disease by a decade.
