Wasn't the blood transfusion more of a one, or few, time thing just to see if they could measure any effect?

AFAIK, they didn't get any effect that they could measure. I think his bloodwork was already really good in the first place. If that's the case, then people don't need blood tranfusion to get healthy.

That's very charitable.

Afaik he only did it a few times and stopped when he didn't see a difference in his bloodwork.

Interesting, parabiosis (merging vascular systems) between young and old mice did have large benefits.
