Number one suspicion: Tolerance. Check against different brand. You may have built up a tolerance. Order from somewhere else more reliable and compare.

Number two: Storage. Heat and packaging can lead to degradation of benzo's. So all the way up the supply chain from manufacturer to user, it has to be handled well. In a perfect world, this means shop at home where the contols are strictest. If we are talking about concerns for quality control in manufacturing you need to find the manufacturer and check their reputation. See if they export to USA, that'll tell ya.

Number three: India has some of the only pharmaceutical manufacturers in the deeloping world that consistantly pass FDA and WHO requirements for bioavailability and quality (Cipla, Ranbaxy, Torrent, and the big names are there as well). The fact that the supply chain from these manufacturers can be hot and sticky may lead to "weak" meds. I have had no problem with the meds I have received from Indianmeds4u and find they stack up against any IOP out there. India gets a bum rap a lot from industry reviews because they don't recognize patents which pisses off many big greedy Manufacturers.

My 3 cents
