There are legitimate trials going on about ALA

And many deal with neuropathy pains. Some are still recruiting-guess it depends on where you live? Look at the trial’s eleigibility criteria and see if you qualify? Then go from there. Sometimes other docs in other areas will participate for one of their patients [or more] but the discouraging part is they’ve got to do a heap of paperwork….as if there isn’t enuf now?
Things to think on tho, when applying, good luck!
