EPO

Erythropoietin (EPO) is a glycoprotein hormone that serves as the master regulator of red blood cell production, stimulating their proliferation and survival in bone marrow. It is widely used to treat anemia and is researched for its neuroprotective and tissue-protective properties.

In the literature, EPO appears most often in work focused on recovery, neuroprotection and cellular repair. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

EPO is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
