I did Google it and found nothing. The closest articles I could find weren't
ScienceDaily, and weren't saying that racetams were adulterated but rather complaining that they are understudied drugs, which is a completely different issue. Hence why I asked you for a source.
Most drugs we're taking here are highly engineered synthetics with the potential for odd reactions from us non-standard reactors. Again, you're not really distinguishing between nootropics and other pharmaceuticals, and I'm not sure why you are so vehemently criticizing my suggestions.
Yes, you're right, I missed it, though I feel like you're going out of your way to criticize every element of my original comments. If you're not careful you might give the impression you have it out for me, or something.
I also feel like a recommendation of skullcap is apposite for a person who has already decided to bear the risks of benzodiazepines, considering skullcap is widely regarded as being weaker (and in the same category of risk).
It's fine if nootropics are not an acceptable risk for you, but the proportion of people here using unconventional treatments is pretty high. Almost any suggestion on this forum is to be taken with a grain of salt - there are always potentials downsides to treatment options for this disease, and I did mention some of them in my original explanation of fasoracetam.
The two are nothing alike. I am not attempting to write off people's experiences of CFS as psychological. I am saying we don't really know what physical basis the disease has, and in what ways that basis connects with the disease's subjective experience. This is not controversial. If we knew these things we'd be that much closer to an effective treatment and perhaps we wouldn't be here having this discussion. When it comes down to it, you cannot reliably know whether excitotoxicity is occurring and to what extent without some sort of objective marker. I am not saying it's not happening, I'm saying we don't know if it is. Sometimes people suffer excitotoxicity with no subjective ill effect (generations of casual amphetamine users might attest to this). Sometimes people have horrible, agonizing experiences from a drug that are in no way correlated with excitotoxicity.
Excitotoxicity is a really specific phenomenon, where neurons are stimulated excessively by glutamate leading to excessive calcium ion influx. Any drug which sufficiently blocks glutamate or calcium channels can prevent excitotoxicity. Plenty of drugs do that - gabapentinoids, NMDA antagonists, memantine (if you need an authority,
here's a good link explaining memantine's anti-excitotoxic properties). However, excitotoxicity is only one subtype of neurotoxicity in general, and any disease state which results in excitotoxicity probably involves multiple forms of neurotoxicity, or other systemic issues which cause the subjective symptoms people often attribute to excitotoxicity.
I agree that excitotoxicity is a contributing factor in ME/CFS but as with many aspects of the disease, I think it is easy to misunderstand one's own pathophysiology. I do it all the time - I think 'boy, it seems like my adrenergic system is acting up', but then I try beta blockers, and alpha blockers, and none of them seem to help, and then I am forced to come up with an alternative hypothesis and admit I was mistaken. All I'm pointing out is that it makes sense to be open minded and not get sucked into the excitotoxicity idea too strongly. Especially when glutamate (the perennial target for us excitotoxicity investigators) has some other really important roles in the body.
Also, separately, if you have a problem with the content of my posts, feel free to message me personally so we're not cluttering up someone's thread.
