Unfortunately TEI has an agreement with some new company "XY" in germany so its only possible to do it with them.
I bought one of my hairtest from "XY" , but they are more than 2x expensive and you dont even get supplement recs. So I dont recommend "XY" at all.
(Hairtest without recs for over 160€ ) You basically pay 100€ just for translation.
ARL is only possible with some kind of practitioner in Germany and there are very little. You have to ask ARL to get a list of german practitioner. And I guess its going to be expensive that way.
My go to is thenaturalchoice dot co.uk but last time they had to cancle because of the agreement of that new company and TEI. So they cant take orders from Germany anymore. So I had to order and send my hairtest from abroad. Results nevertheless will go to your email.
(Hairtest without recs for 60€ and with recs for 85€)
I think you can order it from germany, but you need a post stamp from out of germany to not get in trouble when this company "Naturalch..." sends it to TEI. As TEI are the ones blocking tests from other companys out of Germany besides that partner-company.
Cant unfortunately give you any easy solution
Only overpriced or difficult ones.
Thank you for this detailed answer. I send you a PM, too.
