Putting aside the ookiness factor, the science here seems pretty tenuous. "Self-reported improvements that scientists have been unable to replicate in clinical trials" are what's behind every questionable medical practice from homepathy to crystal healing.

Especially given the time and money involved in having to get regular transfusions, I'd think the practitioners would be better off using the time to spend an extra hour in the gym.

I'm not sure where this quote comes from or even if it's a quote, but over the last couple of years I often read about studies proving just what this controversial startup claims. Reversing aging in mice and better healing through younger blood. The ability to use pre existing stem cells through transfusions of "younger blood" and such. I'm not sure what to think of it especially since it was only tested on mice and I didn't check the credentials of the researchers, but a quick search turned up multiple hits:

I remember another article that I couldn't find right now, but claiming a non reproducibility seems wrong.

Again wouldn't go to this startup and think that many things are wrong here, but plausible at least.

Plus the small but non-zero risk when receiving a transfusion. Disease screening isn't perfect and there are other risks too.

I wonder how much of the improvements are attributed to having more red blood cells in your body that normal, which would allow you to carry more oxygen. This is the theory behind blood doping in sports.

i.e. medical researchers know how to add control groups for placebo effect, amateurs do not.
