i´ve searched with the hive searchengine sveral times for "pseudo HCI, ephdra HCI ratio,.." but still couldn´t find anything usefull.
That is because neither "HCI" or "ephdra" are proper chemistry terms. Correct spelling is "HCl" and either "Ephedra" or "Ephedrine" depending on if you want to refer to the herb or the alkaloid.
Read this: Ephedra's Role As a Precursor in the Clandestine Manufacture of Methamphetamine (https://www.thevespiary.org/rhodium/Rhodium/chemistry/ephedra.html)

Now go UTFSE again.
