I am a former member of another forum site and while on that site many people spoke of pharmacom and I have heard mostly good reviews even sometimes about just Darius him self. I also hear that they ship in mineral oil vials like that are labeled mineral oil in a vials. I believe domestic-supply carry pharmacom, but also alpha... I would go with alpha though because I have used their product in the past until I found an even better supplier! Not going to give away another source but lets just say the best sources are the sources that don't create websites and don't advertise their gear in a webstore..
