As I had replied to someone earlier...
It seems like having it tested or purchasing a reagent test kit and testing it ourselves would just be throwing good money after bad to possibly narrow down exactly what the compound is or is made up of.
It's apparent it does NOT have any d-meth or l-meth whatsoever so testing it just for the sake of identifying it seems like
It very well may not actually be n-iso however...
A. It has been going around here since pretty much the first week of Jan. of this year...
B. It is NOT psychoactive in regards to the classic, very recognizable effects of d-meth and/or l-meth (none of us noticing ANYTHING having to do with dopamine release/re-uptake inhibition or norepinephrine release/re-uptake inhibition. Actually, the first "batch" of whatever landed out here was making many of us drowsy (I myself would actually catch a nod from smoking less than a bowl!) AND one person in our "social circle" used fentanyl urine test strips and said he did in fact pop positive for fetty from that gear that circulated the first two-ish weeks of Jan.

C. It is not going for anywhere near $400/oz...More along the lines of $150...I do not disagree with you, however, on having a price on your head if indeed the Mexican Cartels are being circumvented and this B.S. is some little "homegrown" domestic sadistic Science Fair project!

Obviously Cartel Superlab product is quantity over quality but not flat-out inert!

D. In regards to shelling out $40-$50 just to have a sample GC/MS by a Third Party, meh, not so much...None of us are *that* curious as to what exactly it "is"...we are all 110% sure what it is not though!

It would be interesting to get our hands on the test results from the Orange County Sheriff's Dept. though, considering plenty of the Peeps around here have scored themselves possession citations, paraphernalia citations where there is residue in the pipe, and we're pretty sure the "main street Dealer" was popped for sales about three-ish weeks ago!

HOWEVER (and I'm speaking from personal experience as I have 6 prior sales cases I racked up between 10/2019 and 4/2022), it is NOT S.O.P. for ANY of the law enforcement agencies in O.C., including OCSD, to test any and all products seized.

I have received NUMEROUS Felony charges throughout those 6 sales cases for Fel. Poss. w/intent to sell meth, Xanax bars, 30mg Adderall IRs, Ecstacy, and a few other pills (ALL street pressies) and all items were just charged as appeared from face value (i.e. "White crystalline solid identified as methamphetamine", the color, shape, size, and pill code stamped on the pressies, etc...)
