Familiar with Mexico?🧐

I’m here right now, playa del carmen and I’m looking for oxy lol met a guy who said he had some and is gonna meet me tomorrow at noon. Can anyone tell me tips abt being safe, or like is this a really bad idea?😭😂 I hung out with this guy for a few hours today and idk he seemed like a good guy, but I’m not trying to bet my life on that lol he said I could buy 50 or 100, in sealed bottles. I asked if he would bring them sealed and he said yes. I told him I’m not here for long enough for that, he told me I could buy however many I wanted. I said 25. He said 3.50$ American per pill. Then after we hung out for a few hours (I bought him a beer) he said he’d give em to me for 3$ each. Opinionsssssss
