Nembutal has long been available over-the-counter in Peru and Bolivia. Some positive accounts from Ecuador and Columbia have also been received, and these are under ongoing investigation.
In Peru, sodium pentobarbital is known by unique Peruvian names. The most common brand in this part of the world is ‘Halatal’. A less common brand is called Pento-Hypnol. In Peru (unlike Mexico) Nembutal is sold in small 50ml bottles as opposed to 100ml bottles. However, the concentration is the same as that for the larger Mexican bottles. The concentration of both Halatal and Pento-Hypnol in Peru is 6.5gm per 100ml.
