“The products must be available to all menstruating students in restrooms regularly used by students in grades 4 to 12 according to a plan developed by the school district”

That’s all the law specified. It didn’t state any the about “boys rooms” or “girls rooms”. If a school determined that a “boys room” will not be regularly used by menstruating students, they didn’t seem to need to stock them.

The law was neutral and didn’t seem to even be thinking of trans one way or another.
