"Discovery" is actually Discovery Experimental Development, Inc. (DEDI) They attempted to produce an ephedra plant extract containing
selegiline citrate in liquid form. Somerset pharmaceuticals attempted to sue DEDI to prevent them from marketing selegiline
citrate as a dietary supplement. They lost. DEDI in turn countersued Somerset, claiming that Somerset deliberately marketed
selegiline HCl contaminated with methampetamine in 1990, that this contaminated selegiline caused the death of countless patients,
and that Somerset deliberately attempted to cover this up. The suit names the FDA and the State of Florida (where Somerset is located)
as conspirators, deliberately allowing a controlled substance to be marketed and delivered to unsuspecting patients.

My take on the situation is that DEDI is full of crap. That there might be trace amounts of methamphetamine in a selegiline preparation
is not suprising, given its chemistry. Unless there were large amounts of this drug present, I doubt a patient taking Eldepryl would even
experience any effects. People take enormous amounts of D-methampetamine all the time as a street drug, and it's rare that it kills
them outright, or even after repeated usage. Anyway, selegiline is metabolized into L-methamphetamine by the body, regardless of the source.
DEDI makes other specious and patently erroneous claims. One is that scientists have been attempting to purify selegiline from ephedra for 30
years, failing all the while to produce a stable and marketable form, and in 1991 only DEDI was ultimately successful because they used a
"citra gel" in their preparation. Absolutely ridiculous, contradicting decades of clincal and laboratory research on selegiline prior to this.
Another is that their product is fundamentally different and somehow safer because it contains "citrate" instead of "chloride". This is absurd.
Both are harmless conjugate bases of hydrocholric acid and citric acid, respectively. In selegiline HCl, a molecule of HCl forms a complex with
a molecule of selegiline and aids in stabilization and solubility. Since your stomach is full of concentrated HCl, the minute amounts added by
ingestion of Eldepryl are not worth worrying about. A solution containing either acid in reasonable concentrations, or citrate or chloride salts
will not in any way change the nature of selegiline dissolved in it. Clearly these people feign zero knowledge about chemistry.

DEDI also offers up the results of a 1995 study published in the British Medical Journal, where Parkinson's patients taking Eldepryl and L-dopa
were twice as likely to die as patients taking L-dopa alone in a given time, as evidence of Somerset's criminal conduct. While this is indeed a
disturbing finding, it does not follow that it is a result of methamphetamine contamination, or that selegiline citrate would necessarily fare any
better. A 1998 article in the same journal, and another in the Journal Neurology that same year report findings that do not support the results
of the 1995 study. It's certainly something to think about, but hardly incrimiating evidence.

DEDI wants to market liquid selegiline citrate as an over-the-counter supplement, and did so for a short time in Mexico. They claim the FDA wishes
to prevent them from doing this because the FDA and Somerset are conspiring together to drive them out of buisiness. Again, rubbish. If DEDI has managed
to produce a suitably pure and active extract of selegiline, the idea that this could be sold without a prescription or the close supervision of a
physician is outrageous. Being a chemical capable of acting as an irreversible and non-specific inhibitor of monoamine oxidase as sufficient doses,
it would be dangerous and potentially deadly to market it without the proper controls, and it certainly would never gain such approval in this country
under any circumstances.

I wouldn't assume that all pharmaceutical companies behave ethically 100% of the time. But DEDI's claims are pure fantasy. I wouldn't buy anything from
them just out of principle, but I also would have serious doubts about any product made by a company capable of making such assinine claims.

A web page on the subject is here:

It is a libertarian screed (in counterpoint to my own ;)), but worth reading for a laugh, I guess.
