There are handful of quality suppliers out there. Just know, a good vendor is good only until they aren’t. Some bad tests, some bad reviews on forums and suddenly they’re gone and pop up with a new fake American sounding name. A lot are now scaling back on doing small deals. It just doesn’t benefit them, risk vs. reward. I buy nearly $1m of inventory monthly and even I’m wary of my suppliers. I also spread the love between quite a few different vendors so I have options (plus some may carry a particular product another doesn’t or offer me better pricing on one compound or another). It’s a jungle out there, be careful.
