I wonder how many of these negatives are actually caused by impurities... It would be interesting to see what would happen if everyone took their RCs and recrystalized them to see just how impure they are and how much better they are when all the intermediates, etc,. are gone...
Anyway since I've been on benzos for years I can add commentary on psychedelics.
These are all on Xanax - the only thing I have taken since I switched to Klonopin was MDXX and methylone, neither of which suffered at all from what I could tell.
Mushrooms - virtually unaffected - in fact, the trip got out of control at one point and I had to take more xanax to calm it down.
LSD - I can trip LSD on Xanax but if I take any DURING the trip, it aborts it almost entirely.
5-MeO-AMT - intensifies the trip and does little for the tachycardia if taken during the trip.
2C-I - virtually unaffected but dosing during the trip will dumb it down a bit, little done for the tachycardia here.
I think that's all...
