no, there is no data to back it up other than the paranoid ramblings of drug abusers. in the last year I have had ethex, mallinkrodt, and barr and there is no fucking difference between them.
Begging your pardon, but in the last year I have also had ethex, mallinkrodt and barr and there is a big fucking difference between them. A bunch of other users taking them medically who are neither drug abusers nor paranoid seem to agree with me. So please, if you wish to speak insultingly of other peoples opinions and experiences, please realize that you are not God's sole gift to the universe in the respect that only your opinion counts on things.
For me, ethex and mallinkrodt worked smoothly and effeciently and I loved 'em. Barr feels awful to the degree that I won't continue taking dex if that is all that is available. The problem is not the quantity of active ingredient - it seems plenty strong enough - it just makes most people feel like crap.
Every person is different, and you may experience no difference. Other users however, find the barr brand to often cause headaches, be abrasive on the stomach, and generally feels to be a much "dirtier" drug than either of the other two listed. This may be in part to the way that the raw d-amphetamine that they are using is manufactured and processed, and it is certainly aided the different fillers and binders, the chief one being colloidal silicon dioxide. This is an abrasive material that has no place in food materials
Besides being used as a gelling agent, it also has the following uses:
Refractories
· High temperature binders
· Investment casting - used in moulds
· An abrasive - for polishing silicon wafers
· Carbonless paper
· Catalysts
· Abrasion resistant coatings
· Increasing friction - used to coat waxed floors, textile fibres and railway tracks to promote traction
· Antisoiling – fills micropores to prevent take up of dirt and other particles into textiles
· Surfactant – used for flocculating, coagulating, dispersing, stabilising etc
· Absorbent
This is not a good product to put in one's body and there have been links establishing it as a source of tissue damage by having the abrasive particles mix in with tissue and reside in nodes beneath the skin.
I believe that it also finds its way into the blood and irritates the nerves running throughout the affected tissue and is at least partially responsible for the "dirty" feeling you get from taking this drug. To me, it feels like my blood has sand and acidic chemicals in it.
