I order my hydro from US ops and don't worry at all when using them. I have used IOP's a few times and have been nervous about getting my packages seized from several posts I have seen here on db. Also, since they are overseas, who knows what is going on. I have only used imported for cheaper zanaflex and haven't had a problem yet (one order should be here soon...in transit), but those are the ones that I worry about.
