r/peptidesupplier What separates a peptide supplier worth sticking with from one that's just easy to find?

Been consolidating my sourcing after using five different vendors over the past two years. The ones that were easiest to find through forum searches and Google were rarely the ones that ended being worth it. The two sources I've stuck with both came from specific community recommendations tied to actual test results, not general reputation or review counts. Review volume and search visibility seem to correlate more with marketing budget than product quality in this space. The vendors doing the least promotion are sometimes the ones with the most consistent third-party testing history. And the one I ended settling for was Dragon Pharma through pctshop.com because of the consistent per-batch COAs and enough community run independent tests posted over time. What criteria do you use when deciding a supplier is worth a long term relationship rather than a one off order?"
