When comparing potency of RC lysergamides to LSD, subjectively, we are faced with a huge problem. Virtually all LSD available on the black market is underdosed (i.e. the potency is less than advertised) , in a majority of cases severely so. You have tabs with barely 50ug being peddled as 150ug "fire" stuff.
In this situation, an honest 100ug tab of 1P-LSD might indeed seem equipotent with the 100ug tab you got from a friend, or even from the onions, because the latter is 50ug.
Once you have been using LSD for a loooooong time, and had gone through all kinds of connects, tabs, sources, tested stuff, etc., I can guarantee you you will realize one thing - LSD is freaking astonishingly potent. Much more than we give it credit for.
1P-LSD is not. I'm sorry to say, but 1P-LSD is weak stuff. I wanted to like it, I really did, but it doesn't hold a candle to the real thing. I much prefer AL-LAD, which is different from LSD, rather than 1P, which is essentially half-assed LSD.
