NeuroEpo (Cuba)

A nasal spray from Havana after which my sense of smell improved right away.

NeuroEpo (Cuba)

What is it?

NeuroEpo (brand name NeuralCIM) is a variant of the body's own hormone erythropoietin, or EPO for short, which is best known as a doping agent. The Cuban form was modified so that it hardly stimulates blood formation anymore and is mainly meant to protect nerve cells: against cell death, oxidative stress and inflammation. It is given as a nasal spray so that it reaches the brain as directly as possible through the olfactory nerves.

NeuroEpo is made at the Center of Molecular Immunology (CIM) in Havana, and treatment takes place at CIREN, the International Center for Neurological Restoration. It is not approved outside of Cuba.

What does the research say?

The evidence is thin and comes almost entirely from Cuba:

My experience

From November 14 to December 5, 2022, I was at CIREN in Havana. I received NeuroEpo three times a week, plus four hours of physical therapy every day for two weeks. I had no side effects.

My sense of smell improved clearly after the very first dose, my left arm swung along again when I walked, and my walking became smoother. How much of this came from NeuroEpo and how much from the physical therapy cannot be separated. My neurologist also noted that my sense of smell and motor function improved once more afterward.

In September 2024 I spent a second two weeks at CIREN. I still take NeuroEpo today, partly with breaks. My supply will last until about early 2027. Whether I can get more after that is uncertain.

Effort and costs

Calculated over three years, with treatment, travel and ongoing NeuroEpo, Cuba costs about as much as my stem cell therapy, or more.

My conclusion

NeuroEpo is not a miracle cure, but for me it is an important building block, right after the three most important ones. Its effect is barely proven scientifically, and the route through Cuba is expensive and a lot of effort.
