Sorry for taking so long to reply. I just haven't been on my laptop very much. The PEA I take is Lake Avenue Nutrition PEA (Palmitoylethanolamide). They are on Amazon.... link below. These are 300mg and I take 2 of them twice per day. You can take up to 1200mg twice per day though per what I've read at http://www.arachnoiditishope.com and on the NIH website. Maybe start out at 600mg for a month and if you're still not getting enough relief go up from there. I say a month because you have to take it for awhile before notice some relief. Have you read the article on the NIH website? Here is the link for you https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5094513/ There's a bunch of scientific stuff but try to kind of skim through it. Read the article but pay most attention to the chart they have with the different doses for different kinds of pain. Please let me know if it helps you! Best of luck!
