How should I schedule the stem cell injection cycle?

I recently became interested in this while looking into immune system management and improving my condition.

Since the explanations vary slightly from hospital to hospital, I am most curious about the stem cell injection cycle.

Some places recommend a short interval, while others suggest intervals of several months.

So, I am curious how those who are actually undergoing treatment manage their stem cell injection schedules.

I would like to know if getting just one injection is sufficient, or if I need to follow the injection cycle and continue treatment consistently to feel the effects. Haha.
