Well, I do appreciate your trial but I must tell you that Mestinon is not necessarily made in the U.S. The syrup is made in Puerto Rico. My last batch of syrup tasted like pesticides. Not that I've ever tasted them but it tasted like they smell. I have reported that, plus sent samples back to Valeant. I might file a complaint with the FDA but I doubt they'd do squat.

Anyone know where they make the Mestinon brand pill by Valeant?

The generics don't go through the same rigorous clinical testing and, as you must know being a chemist, that they are not the same exact formulation.

Thanks for sharing your results with everyone. A lot of people have problems with the tablets crumbling, especially in the summer when "cool, dry places" are at a shortage. It's too bad that the brand Mestinon is not as inexpensive as the generic. That's a concern for a lot of people.

Take care.
