Hi @peggyn...I have posted on a couple of topicals. The one I was able to order was PEA Cream. I do not have it yet but did get the 100% pure PEA from a company in the Netherlands. I was available on Amazon. The PEA cream I ordered from Vitalitus LLC. It has not arrived yet. It's brand name is Soothamide - PEA 2% Topical Cream. I have not been able to find Phenytoin cream which has positive studies. BTW PEA is abbreviation for Palmitoylethanolamide. You can read about it in a brief study in the British Journal of Clinical Pharmacology. This study covers the PEA capsules, not the topical. I am working up to 1200 Mg/day. I cannot post link on this site but look up "Palmitoyethanolamide for the treatment of pain: pharmacokinetics safety and efficacy" Revised May 20019. The authors are from Sweden. This paper is based on 16 clinical trials. Onepaper on the topical PEA was pucblished by the HIH. Look up "Therapeutic utility of palmitoylethanolamide in the treatment of neuropathic pain associated with various pathological conditions: a case series" Published 2012. I'll be posting more on this in the future I am certain...Pam
