I've always run in the right circles to find good L having gone to school in Burlington Vt and toured the Biscuits for a bit. Recently even the (real) festival scene (as in the smaller, non-Insomniac/EDC events) has been slammed with LSD-like RCs. And not the typical bullshit I can quickly verify not to be acid, these chems mimic every field test I am able to employ.
Duration, general effects, taste, doseing, ect are all the same as one would expect with Love. The mindspace is far more muddled however, with periods of increased anxiety that I've never had on L. I've seen it floor some of my more L tolerant friends for hours. I'm wondering what it might be, it's nothing nasty, I generally hate RC Acid, and I can tell 2c chemicals (and enjoy several of them). So there not N-Bombs or 25i, I can't imagine what they might be. If I wasn't expecting the clean, clear acid headspace, I would have enjoyed this chemical (in fact, I loved it 2/5 times, and only disliked it once). However as the sheet comes to a close (after a full year of using it for shows) we have accepted its not L.
