There are some vague parts of the analog act, but it is very clear that it only applies to analogs of Schedule I and II substances. All scheduled benzos are Schedule IV Federally, so any analog would not fall under the analog act.
Caveat: Rohypnol (flunitrazepam) is Schedule I in a few states. So nonscheduled benzos and similar molecules would fall under the state analog law in those states only.
There may also be state or local laws regarding imitation controlled substances, and police will likely harrass you about any pill not in a regular pill bottle with a label that is up to standards (blister packs from India, even if unaltered, may not be considered proper packaging under laws of certain states). The charge might not stick in court, but still.
