Having worked in pharmaceuticals I can tell you a couple of things.

1. You usually get what you pay for - order from an outfit that "underbids" and you will get generic junk - from an outfit probably located in Bangeldesh - with poor quality control etc etc etc.

2. There is also something known as bioavailability - but that is kind of technical to go into unless you have some background in pharmacology.

3. The "fillers" - or what they use to bind product together are usually of poor quality in the lesser generic houses - pills crumble and degrade quickly - cheap dye is used - etc etc.

4. How do you know what IOP is offering what - simple - send them an e-mail as to what "brand" they are offering. If they don't answer you - don't do business with them.

5. Yes, quality does vary very much from generic house to generic house unfortunately - many are comparable to throwing together stuff in someone's basement - others are reputable generic houses.

6. A company - example Roche - the original "inventors" of Valium - have patent on product that usually lasts 18 years - and for those 18 years ONLY that company may manufacture the product. After patent expires it is up for grabs by any generic house. Roche and many larger pharmaceutical firms have their own generic houses - gets very complicated.

Best advice I can give you is to deal with a reputable IOP - best one I have found is Our Prescriptions for Less - if you have any TYPE of a problem with anything you order from them, they are very responsive.
