Does anyone know if Pirenzepine is on a schedule controlled list in the US? I'm asking because I've noticed an irregularity in the normal path my packages takes just before arriving (its almost to my front door) when using the tracking number I was given. I've never seen a package take this path before. I've googled every possible way I could such as "Is Pirenzepine a schedule controlled substance" with no results saying it is. Anyone know? Thanks in advance for any and all info.
