This whole topic. Ive been in this coversation 100 times and based on hundreds of hours of research the most likely scenario to explain the discrepancies in peoples observations is ( insanely this is the only way that checksnall the boxes). Mandela affect. I'd like to agree with you about the n-iso, but according to Drugsdata, and independant testing lab who was started by Erowid, who have tested at least 10,000 drugs said that N-iso has a very different nmr signature with different wavelength spikes, and they have bought thereferrence standard twice, to be sure, Only 1 time ever did they detect it in a sample. I dont think they're lieing. The DEA says the meth they have seized coming out of Mexico is pure D(R) but the shit i bought in 1999 for $100/g was an order of magnitude more stimulatory and euphoric. That's another topic, drugs are cheaper today than they were 25 years ago. WAY CHEAPER when you consider inflation. Calculating enflation over 25 years illicits a result that suggests $100 1999 dollars is the same as $200 2024 dollars. I'M PAYING 1/10 OF THAT.
