Dr. Conrad Murray -- Propofol Still An Option

Dr. Conrad Murray has absolutely no restrictions on his ability to administer Propofol -- the drug that killed Michael Jackson.

We did some checking ... Dr. Murray still has full privileges to practice and operate at Doctors Hospital Tidwell in Houston. We're told Propofol is available for Murray's use.

As for ordering the drug ... no problemo. Dr. Murray can, if he chooses, get bottles of Propofol without special limitations.

As we previously reported, Dr. Murray -- who is seeing patients again -- is being investigated by the DEA and the LAPD in connection with Michael Jackson's death. The Texas Medical Board is also taking a look at the good doc.
