I've been feeling really tired lately, so I've been looking into treatments and searching for posts about the longevity of stem cell injections. However, opinions vary more than I expected, so I'm getting confused. Some people say the effects last quite a long time, while others say you need to get them every few months to feel the results, so I'm really conflicted. I'm curious to know how long you actually felt the effects last. I also want to know if it feels like a one-time treatment or if I need to manage it periodically. The cost is also a factor, so I can't make a decision easily.
