Is Zenzedi even in Los Angeles area pharmacies?

Hi, I'm hoping to find a pharmacy that carries Zenzedi (or other non generic dextro) in the Los Angeles area. I've been trying to fill my prescription for Desoxyn for a month, and it's honestly a nightmare. My regular pharmacy says it's unavailable. They say they're "trying" to order it but it's out of stock. The way I've been treated when I call around to ask is unbelievable.

So I'll be refilling my dextro 10mg soon. But I keep hearing that the brand name is much more effective so now I'm trying to get that. Any suggestions for a legitimate pharmacy solution in Los Angeles would be greatly appreciated. Please don't DM me with some telegram handle for an overseas pharmacy. Supportive or useful comments, please. I really do appreciate this sub.
