I am still alive. I bought my N back in January (I now have three bottles two for myself and one extra, just in case) and I have helped several others by meeting them in Tijuana, Mexico and helping them by translating for them. I DO NOT sell N. I DO NOT have N to sell to any one.
Since October of this year finding N, even in Tijuana, Mexico has become near impossible. The shop that I have used in the past can not seem to get it any more. From information on this site, it looks like Peru would be your best option, IF you are fluent in Spanish. You can't just buy N over the counter, at least in Mexico. The shop I used is run by a family where the parents run the pet supply store up front and the daughter (an actual veterinarian) ran the small clinic at the back of the shop. The daughter would write the prescription so the shop wasn't doing anything illegal.
You will most likely need to tell a story to the owner of the shop about " your very sick Saint Bernard whom you have owned since it was a puppy. YOU want to be the one to administer the shot to your beloved pet that will put it to a peaceful and stress free sleep forever." All in Spanish! You can't just walk into a pet supply shop and say, "I want to buy N because I want to CTB." Sadly some people on this sight seem a bit delusional and think the process is that simple... It isn't. In the past, I have not charged for my help, but I have asked that the people whom I have helped pay for my expenses (flights, hotel, food, taxis) and give me a tip, if they want to provide a tip. I am not rich and I will not be traveling and translating for people out of my own expenses, but I am willing to help other people out if they can pay for my expenses.
I wish you good luck in your search for peace.
