Does it have to be R30 or higher? I'm wondering because lately a lot of the R10, R15, and R20 batches have been having issues—turning cloudy when mixed with Hospira. Some suppliers, GYC included, are even warning upfront that PBS might be needed for reconstitution. That said, I did just receive R10 from an unnamed vendor (mostly used for bulk/GB purchases), and there were no problems with it.
Aside from Uther and PGB, JEC looks good on testing based on what I've seen, and I haven't come across any odd complaints about them. They don't have a US warehouse, though. I'm keeping an eye on them since one of my GB groups relies on them. However, they don't have as much 3P coverage for things like endotoxins and sterility—at least not consistently over time like Uther and PGB do.
