I have bought some LSD from a few big name vendors. I had a few great batches. The last few I had from them have been weak compared to their prior stuff. Has anyone else had any issue with this? Or is your tabs just as good as before if you have had multiple orders from the same vendors?
How long has it been since you had their great batches? If you've been using LSD regularly you will find tolerance builds up quickly. The Grand Wizard has also found that there are only so many lessons any psychedelic has to teach you: after that you'll find the visuals and spacey feelings may still be there but the magic is gone. Not saying this is what is happening in your case, but it is definitely something to consider.
