Everything i read says RSD is prevented by giving 500 mg over a few months after injury. I assume that’s orally. If so, what percentage of that is actually being metabolized and getting into the blood? I assume there is a reason nobody has been cured by that (assuming nobody has). You can take dozens of supplements a day and eat super healthy but potentially only absorb a very small amount of nutrients. And, if you are sick, there is a chance you are going to have a harder time metabolizing vitamins.
So, what happens if you take away that variable and you get it pushed right into your bloodstream? That’s 500 mg a day that you may or may not absorb vs 10-20 GRAMS (or even as many as 100 grams) injected directly into your blood for 90 minutes once a week for 8 weeks.
