Question Extraction from Ephedrine pills

[Jxll]

Hello, I'm a beginner chemist and want to cook my first batch soon while using the "Ephedrine extraction method".
I'm wondering, which Ephedrine pills should I use and where I can get them.
Should I use Ephedrine HCI/L? Or Ephedrinium Hydrochlorid? And if it is the latter which one(D6/D4/etc.)
Now where to get them.. Ephedrine(HCI/L) is a prescription drug where I live so I thought about ordering them online. I don't know which sites to trust and what exact product to look for so I hope ya'll can help me with that.
Thanks in advance!

There is also the option of getting psuedoephedrin however the pills also contain cetrizine.
