That said,my ex-wife worked for a Doctor that was dying of cancer and she had liquid IV vials of dolophine/methadone. This was quite a while ago so i don't know if they still make it but these were Eli Lilly and came in multi dose vials. 25 cc/ml. She would buy it by the case of 10 bottles (ten pack) and at the time my wife was her "nurse". When she died there was 4 and a half bottles left and swim got them. This stuff was clear as water and kicked ass in a major way. Not a big rush but very potent.
