Real UEI and FST from the creator of these two extracts contain no mitragynine or kratom alkaloids at all with the exception of the base powder in the case of UEI (FST was tested by a VERY intelligent BL'er, there's also several little birdies that have shared some valuable info on this topic)
It's suspected to contain a very potent analog 30x stronger than morphine named Mitragynine Pseudoindoxyl, with confirmed delta and mu opioid activity, no mentions of SNRI activity associated with this compound... Comparing both UEI and FST to kratom is like comparing two different drugs altogether. These two extracts are still quite the controversial mystery though... Can't speak for Gold Reserve either, shit is expensive and inferior to genuine UEI IMO.
(I can dig up and PM some links if your interested on the subject)
Mind digging those up for me? Especially how the death was determined to be by any sort of SSRI/SNRI/monoamine interaction, or any interaction that suggests SSRI/SNRI activity was the culprit? There's only been three
documented deaths (I'm sure there's more sketchy undocumented cases containing other drugs) and can't find any deaths attributed to Modafinil/kratom or MDMA/kratom. There was however a seizure when a SC dilaudid user took both modafinil and kratom in WD.
Since I don't have access to a university or library computer with access to the last article I'll just link it for those who do.
Anyways, let's take a look at the case below. You know, the case report where they try and blame kratom and propylhexadrine as the cause of death yet go on to say that the subject also morphine, promethazine, and acetaminophen in his system?

How about this report, just a bunch of deaths attributed to headshop products
laced with O-desmethyl tramadol...

Like I said, the only thing I could find on the "deaths" you speak of is a case where an older man suffers a seizure from combining modafinil and kratom. Not only do both opioids and stimulants lower seizure threshold (yes, all opioids lower seizure threshold to some extent), but kratom also contains all sorts of adrenergics in itself so it comes as no surprised that the occasional seizure may occur given the right circumstances. Not to mention this is an isolated case and seizures associated with kratom consumption are not commonplace.
The patient was fine btw, no death, no mention of serotonin syndrome either.
For some reason I don't think you understand just how dangerous it would be to mix an MAOI with an SSRI/SNRI, comparing an LSD/cannabis combination to an SNRI/SSRI/MAOI combo shows that your uninformed on serotonin in general, I would advise you do some research as there's plenty of target sites for serotonin, and just because something "works on serotonin" doesn't mean it carries the same risks with combinations as a serotonin/norepinephrine reuptake inhibitor

.
LSD is NOT an SSRI nor an SNRI, it can even be mixed with an MAOI in reasonable amounts like a good majority of serotonergic psychedelics. Find me some reports of serotonin syndrome from kratom and an MAOI consumption and maybe we could work from there, that would hint at SNRI activity, but still not be conclusive evidence... just something for us to go on.
I won't even go into the wholeSSRI/SNRI withdrawal from kratom either since again, this isn't the right place. But fyi, there are several reports of kratom doing very little for SSRI/SNRI withdrawal and after reading through just about all of the kratom megathreads, there have been no complaints of this phenomena. Seems kind of funny being that you were at one point, addicted to an SSRI, but I digress.
Here's the third documented death for anyone with university access, curious as to what this one claims
