egor, a 98% thp extract (I do not know whether it's D, L, or R, sorry) that I have certainly gives effect beyond placebo at 30mg. It gives hypnotic, muscle relaxing, pain relieving, anti-spasmodic effects. 50mg makes me feel so fatigued that crashing on a cushy surface is practically inevitable. I have never experienced euphoria with it, though that was never my goal with it in the first place. IMO this chemical has a lot of potential and I honestly don't understand why there isn't more chatter about it.
I was also wondering if anyone had experience with combining THP & 3-meo-PCP. (My apologies if I'm asking in the wrong place, but this thread seems to have the most info on THP on the entire forum).
Thread necromancy, whee! %)
