Young blood transfusion refers to transfusing blood specifically from a young person into an older one with the intention of creating a medicinal benefit.<ref name="sbm"> ,

Research
Experiments at Stanford University on pairs of old and young rodents placed into parabiosis suggest that the circulation of blood from young mice seems to invigorate older mice.<ref>,

In experiments like this, researchers found that some of these mice died quickly (11 out of 69 in one experiment) for reasons the scientists could not explain, but described as possibly some form of rejection.<ref name="sbm" /> Amy Wagers, a researcher who coauthored several mouse studies on young blood transfusion, has said that her papers do not provide a scientific basis for some of the existing human trials.<ref name="sciam"/>
Evidence from two large studies in 2017 showed that the transfusion of blood from younger donors to older people led to outcomes that were either no different from, or led to worse outcomes than, blood from older donors.<ref name="sbm" /><ref name="Garraud20172">,

Commercial development
In February 2019 the FDA warned about companies offering young blood transfusions stating: "simply put, we’re concerned that some patients are being preyed upon by unscrupulous actors touting treatments of plasma from young donors as cures and remedies. Such treatments have no proven clinical benefits for the uses for which these clinics are advertising them and are potentially harmful. There are reports of bad actors charging thousands of dollars for infusions that are unproven and not guided by evidence from adequate and well-controlled trials. The promotion of plasma for these unproven purposes could also discourage patients suffering from serious or intractable illnesses from receiving safe and effective treatments that may be available to them."<ref name=FDA2019>

Ambrosia
A startup company, Ambrosia, has been selling "young blood transfusions" for $8,000 since 2017 under the guise of running a clinical trial, to see if such transfusions lead to changes in the blood of recipients.<ref name="sbm" /><ref name="Trends20173">,

Jonathan Kimmelman, a bioethicist from McGill University, suggests that Ambrosia is running this as a trial as they would be unable to get FDA approval to sell this treatment otherwise.<ref name="Max20173" />
On February 19, 2019, Ambrosia announced it stopped testing the treatment, responding to concerns from the Foods and Drugs Administration.<ref name=ars> Mole, Beth,

Alkahest
Another company, Alkahest, was founded based on the Stanford rodent studies. As of 2017 it is collaborating with European pharmaceutical company Grifols to create a blood plasma-based experimental biologic drug which they propose to test on people with Alzheimer's.<ref name="Trends20173"/><ref>,

Young Blood Institute
As of 2018 another organization, the Young Blood Institute, promotes young blood transfusion. Like Ambrosia's, its trial had no control and charged the participants for entry, in this case $285,000 per person.<ref name="sciam" />
Dipnarine Maharaj was running the trial; he has offered both traditional treatments and nontraditional treatments such as stem cell banking in the past.<ref name="sciam" /> Additionally, he has ties to the Hippocrates Health Institute, an organization promoting unproven alternative medicine.<ref> ,
