How often should I receive stem cell intravenous injections?

I've been feeling extremely fatigued lately, so I'm looking into intravenous stem cell injections, but every hospital gives me different advice.

Some places recommend injections every two weeks, while others say to do them every month, so I'm really confused.

I've heard there's a method where you get intensive injections at first and then extend the intervals later. For those of you who have actually tried it, what was your experience like?

I'm also curious how many sessions it took to feel the effects.

I'm worried that I might be pushing myself too hard, so I'm leaving this question here.
