I was recommended intravenous stem cell injections at the hospital because of fatigue and a weakened immune system.

I was told that I need multiple injections rather than just one to see results.

However, I'm confused because the number of injections varies so much from hospital to hospital.

I'm wondering if the effects are maintained better as the number of injections increases,

or if I should focus intensively at the beginning and then space out the sessions later.
