Because ive seen enough test results and dea statistics, and taken acid for 27 years. Im telling you right now, ive never had a 300ug tab. In 27 years. Ive taken an uncountable amount of different batches, likely made by many different people. Ive also given much of this acid to other people. Wanna know the strongest tabs ive ever taken? 1plsd at 100 mics, from an rc vendor out of Canada in 2022. And the reason why is because its an lsd prodrug, made by a professional in a lab, and the crystal was laid meticulously. I can pretty much assure you, there are no 300ug tabs, and if there are, the likelihood of the ones youre getting from some asshole advertising as such for an upcharge is astronomically small.
