It took approximately six weeks after harvesting for the stem cells to be prepared for my first round of injections, which was done in South Korea.
The injections themselves were administered in Japan over two days per session: a spinal injection on the first day, which takes around 10–15 minutes (followed by about 2 hours of lying flat without raising any part of the body), and an intravenous injection on the second day, which takes approximately three hours (or vise versa).
