The main brand of Nube that was being distributed in TJ was Astra Pharmaceuticals Nalbuphine HCL, and it has been discontinued by the Company. NOTHING in TJ that can be gotten in a Farmacia is TOTALLY regulated by the Mexican Government bro, so that was most likely some guys excuse for not having it or something to that effect. It can still be found in 10mg 1cc amps in SELECT places as Nubain SP though, but is more expensive than the Multi-use Vials, as amps usually are.
