R30 or above? I only ask since some of the R10, R15, and R20 seem problematic lately with getting cloudy with Hospira, with some vendors like GYC saying in advance that PBS may be required for recon. But I recently got some R10 from a no-name vendor (more for bulk/GB orders), and it was fine.
Outside of Uther and PGB,
JEC seems to test well, from what I see, and I don't see any unusual complaints for them. No US warehouse though. They are on my radar since they are used by one of my GB groups. But not as much 3P for them for various things like endos and sterility, at least not over time compared to Uther and PGB.
