So 3 out of the last 4 LSD vendors have sent me some "white on white" that was either yellow or turned dark yellow after holding it for a few weeks. I've tried this shit and it's not LSD. You do get LSD like visuals but it makes you feel shitty and gives you anxiety. I have tons of experience and have done LSD hundreds of times. This bullshit appears to be widespread. Anyone else have experience with this? I did a search and it seems something called 1P-LSD is making the rounds among research chem vendors...

Did you learn nothing from Woodstock? Don't take the brown acid.
