On the original research that started this poll; Young pig blood fractions called E5 (which do contain the EVs from the above post) led to a 10-20 percent increased lifespan in the test rats (versus controls); and rejuvenated the rats as well. Similar tests by another group using mice and neonatal mouse plasma also show rejuvenation effects, but was not carried to aging death.)
Waiting for the preprint - any time now.
