It seems very unlikely that you would get a legit source even then. China, Mexico, and SA countries have cracked down hard.
I've only ever seen one person (in recent years) get it on a DNM (supposedly), but they never had it sent to a lab for testing and the concentration was off meaning at the very least it had been repackaged and wouldn't have lasted for long.
One user has claimed many times that it can be found under different brand names, but I am highly skeptical of this seeing as, afaik, no one has ever bought it successfully (aside from that one person who may have).
