Also be aware many of the "Made/Maufactured in/Product of the [INSERT COUNTRY]" claims are also false. Email some of the companies, ask them in depth questions about the products they sell. Chances are most of them;
will know next to nothing (resellers of Chinese peptides trying to make some quick money at the expense of people and know nothing of what they're selling)
will know a bit but speak in broken/incorrect English (Chinese resellers with an English front OR just somebody will little/no education - not someone you want to buy peptides off)
will not reply to your emails in a reasonable time frame (either of the above or don't care about customer service - also not someone you want to give your money in case there's an issue with the order)
