Just go buy $100 in street ketamine (still marked up 100x, fwiw, also because laws) from someone reputable, test it for fentanyl, and blow lines of it. Same deal, $1900 less cost. Breaking some dumb rules is far preferable to living with untreated depression.
You get to decide whether you want racemic or S-Ketamine, and your money is held in escrow until you've got the product and release the funds to the vendor.
