After 30 minutes he finally reached the other guy and, within 15 minutes, I had 3 bottles of Halatal in my hand. I paid 162 soles in total. The seals were intact, and shelf life was [a year from the date of purchase].
This Agroveterinaria is a small place in the green and white building that also houses the “Asociacion de sub-oficiales tecnicos y especialistas de la policia nacional del peru”.
One can barely see its corner through google street view, next to the orange house. It´s quite ironic that a place that sells Nembutal freely shares the same building with police officials. The place sells all sorts of medicines, and, based on the many customers I saw while there, it´s the go-to place to buy things without prescription.
Note - the AgroSuni store is no longer housed in the Police building. Only the AgroSuni offices are co-located now with the police.
