My two cents:
I am not certain, nor do I have proof. But i am pretty sure the last two times I got 10/325 (Watson 853) from .... with my (ahem) TJ prescription. They worked OK, but not the same.
The imprints looked just slightly off. That was over 2 months ago. I am not sending that kind of money for fake meds.
The Cartels could be cooking them themselves and that is fine. I am just not buying.
