What is erythropoietin and what stimulates its production?
Erythropoietin (EPO) is a hormone that is produced predominantly by specialised cells called interstitial cells in the kidney. Once it is made, it acts on red blood cells to protect them against destruction. At the same time it stimulates stem cells of the bone marrow to increase the production of red blood cells.
What is erythropoietin and where is it produced?
Erythropoietin (EPO) is a hormone produced primarily by the kidneys, with small amounts made by the liver. EPO plays a key role in the production of red blood cells (RBCs), which carry oxygen from the lungs to the rest of the body. This test measures the amount of erythropoietin in the blood.
What is the function of erythropoietin?
Erythropoietin, also known as EPO, is a hormone that the kidneys produce to stimulate production and maintenance of crucial red blood cells. The hormone does this in two ways: First, it stimulates bone marrow cells to produce red blood cells.
How is erythropoietin production stimulated?
Recombinant erythropoietin drugs are known as erythropoietin-stimulating agents (ESAs). These drugs are given by injection (shot) and work by stimulating the production of more red blood cells. These cells are then released from the bone marrow into the bloodstream.
How quickly does erythropoietin work?
How soon after starting EPO medication will I feel better? It will take time for EPO medication to work in your body. Most people take 1 to 2 months to feel better.
Why is erythropoietin banned?
The drug erythropoietin, often called EPO, is banned from sports because it is believed to enhance an athlete’s performance and give people who use it an unfair advantage over unenhanced competitors. EPO thickens a person’s blood, which can lead to an increased risk of clots.
Is EPO bad for you?
It is well known that EPO, by thickening the blood, leads to an increased risk of several deadly diseases, such as heart disease, stroke, and cerebral or pulmonary embolism. The misuse of recombinant human EPO may also lead to autoimmune diseases with serious health consequences.
What are side effects of erythropoietin?
Common side effects
- Allergic reaction. Rarely, some people have an allergic reaction to erythropoietin.
- Feeling sick or being sick. You may feel sick during treatment with erythropoietin.
- Diarrhoea.
- Blood clot risk.
- Headaches.
- High blood pressure.
- Muscle, joint or bone pain.
- Flu-like symptoms.
How much do EPO injections cost?

How long does EPO last in the body?
In addition, EPO is short-lived, remaining in the body for as short a time as two days.
Can EPO be detected?
EPO, or erythropoietin, is a natural substance produced within the kidneys that stimulates the creation of new red blood cells. Blood-boosting drugs like EPO, if injected, are only detectable in the urine or blood for a short window of time.
How good is EPO?
Improves 3-K time by 6%; effects last at least four weeks. A new and nicely designed study of EPO’s effect on distance runners has shown that four weeks of every-other-day injections improves 3000-meter running time by an average of 6%.
Has anyone died from EPO?
Has anyone died as a result of blood doping? Despite anecdotal evidence surrounding a number of untimely deaths it has proved difficult to conclusively attribute them to EPO. Between 1987, shortly after athletes are believed to have begun using EPO, and 1990, 20 young Belgian and Dutch cyclists died.
Does EPO actually work?
The answer, in short, is that EPO didn’t do anything to muscle fibers and blood vessels. Training (with or without EPO) increased fiber size, capillary density, and several other parameters; EPO didn’t make it better or worse.
Do EPO supplements work?
How quickly does EPO-Boost work? In clinical studies, EPO-Boost active ingredients were shown to significantly increase circulating EPO levels in seven days. Significant increases in endurance and VO2 max were observed at 28 days of use.
What supplements increase EPO?
Echinacea is an herbal supplement used by endurance athletes for its performance boosting properties. It is thought that Echinacea improves the blood’s oxygen carrying capacity by increasing production of erythropoietin (EPO), a glycoprotein that regulates red blood cell formation.
