What E5 Plasma Fraction is
A cleaned-up part of the blood plasma of young pigs, given to old rats. It more than halved the tissue age of their blood, heart and liver. No person has ever received it.
No person has received E5. There is no registered trial in people of a pig plasma fraction for ageing.
How it works: Not worked out, in any species. The paper measures outcomes, mainly tissue-age clock readings and organ function markers.
Approval history: Not approved anywhere. ClinicalTrials.gov lists no human study of a plasma extract from pigs for any ageing use. This is a research product only.
How FDA treats this kind of product
Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.
The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration listings for E5 Plasma Fraction on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
E5 Plasma Fraction in sport and the military
Whether E5 Plasma Fraction is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United States. Before you compete or get tested, look up E5 Plasma Fraction by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.

- Global DRO (check a named product)
- USADA (US athletes)
