FYI: I also confirmed that Watson 387 is hydro 7.5/750 which is generic vicodin ES.

I wonder how long it sat on the shelf or the 150 degree storage locker (years?). I still don't trust these OPs and think their pharmacies (Clinical Solutions in this case) buy expired medicine in bulk from some shady grey/black market and dump it on unsuspecting fools (like me) who buy from them over the internet at outrageous prices. I had their Watson 540 hydro 10/500s a few months back and also found them weak compared to what I had gotten from legitamite local drugstores. I could eat them like M&Ms with little effect. oh yeah, that reminds me of a random wish - why don't they make pure hydro without APAP like hydrocontin?

Here's another reason your pills may be weak: Most people try to get as much hydro as possible per pill at the prices these rip-off artists charge and I am sure the bulk of their hydro orders are for 10/500s (since I don't think they sell generic 10/325's), giving another reason why your 7.5/750s may be sitting around even longer once they get them out of the 150 degree storage lockers.
