It's not necessarily about finding the cheapest product. Many people can't afford $300 -$1000+ per month. I source from China because I can't afford it otherwise. This is something I think big pharma doesn't understand. They seem to think everyone will run to them if they can eliminate the competition. But the fact remains, MOST people simply can't afford $1000+/month. Many can't even afford $300/month... I know I can't.
There are a whole variety of ways to get direct China peptides, some are safer and more trustworthy than others. You can run to cheap pop up vendors who don't test or you can use tried and true vendors who only supply to an elite group, have a great track record, and do extensive testing. I've seen decent improvements by vendors in the short time I've been here. Hopefully they keep improving.
And, as others said, the clientele is diverse.. there are those who would have no problem injecting something they bought from a stranger in a dark alley, all the way up to those who are skeptical of name brand peptides from Big pharma.
