BMAA (Beta-Methylamino-L-alanine) poisoning?

Around the autumn of last year (2018), I started getting a symptom that didn't make any sense, but I didn't make anything out of it at the time because it was isolated. Then, in the winter, another symptom of a related nature appeared, and upon investigating, I lighted on the possibility that a substance called BMMA (Beta-Methylamino-L-alanine: https://en.wikipedia.org/wiki/Beta-Methylamino-L-alanine), which gives rise to Amyloid Beta (https://en.wikipedia.org/wiki/Amyloid_beta) plaques, may have been used against me as a toxic substance that can cause neuro-degenerative disease. 

It turns out that such a substance would be very hard to detect, because it is a naturally occurring compound--an amino acid that is 'nonproteingeneic' and has pathogenic action by replacing the amino acid l-serine in the construction of normal proteins in the brain, giving rise to a misfolding of the proteins that generates the aforementioned plaques and tangles associated with neuro-degenerative disease. 

It is an insidious substance that causes an insidious disease, making it triply insidious for use as a poison to deliberately afflict someone with the insidious disease. More importantly, the CIA, MI6, GDSE et al. have been (and continue to) conduct psyops against me, with defendants like Roughan and Abdelsamad trying to portray me as mentally ill when I filed the lawsuit against the CIA with them as defendants.

In other words, even if you could prove that you had been exposed to BMAA, it would be hard to identify the source, on the one hand, and on the other hand, the amyloid plaques and tangles that it gives rise to are only associated with Alzheimer's disease, though BMAA poisoning is perhaps more directly associated with ALS given the research that has been conducted with respect to Guam by scientists including Paul Cox (https://www.mdmag.com/journals/mdng-neurology/2016/march2016/does-blue-green-algae-cause-als-paul-cox-phd-is-on-a-global-quest), currently affiliated with the Brain Chemistry Lab: https://brainchemistrylabs.org/overview-1.

Since I have a little background in biological sciences and do some medical translation on occasion, I contacted the aforementioned lab to see if I could participate in their study remotely, since they have developed a technology for testing BMAA in hair samples, etc. That was in April, and I didn't hear back from them, so, I decided to take measures recommended in their literature and elsewhere by ordering some L-Serine through eBay from sellers in the UK, but twice the deliveries were claimed to have been lost in the mail. 

The second seller has refused to provide the tracking information. Suffice it to say, I have yet been able to acquire the amino acid after more than two months since first ordering some, and the circumstances are suspect. I should be receiving some in the mail soon from other sellers, and have turned to other indirect sources in the interim. 

Another natural therapeutic material I attempted to acquire also resulted in suspicious circumstances. That relates to bark from the mamala tea of Samoa, which produces a substance called prostratin that is also a subject of research by Dr. Cox et al., and is being conducted in conjunction with UC Berkeley:

The only online source of that refused to answer a query I sent through their website, then proceeded to delete the website, which now gives a page saying, "Under maintenance": http://mamalatea.ph/. The company promoting itself as a vendor of mamala bark tea is:

Company Name:

Operational Address:
1012 Celesta Bldg, Manila, Philippines

Website: http://www.mamalatea.ph

Website on alibaba.com:

Most recently, I contacted the same company that claims to operate the above webpage over Chinese online retailer Alibaba, but they refuse to respond. Here is a record of the (one-sided) exchange:

Eventually, I wrote to the Brain Chemistry Lab again, and received a cordial and informative response, as follows, but have not had time to follow up with them.
