My friend told me that he is not particularly familiar with that combination but has once before combined a phenethylamine and a tryptamine. My friend isn't too law-conscious and commits illegal acts that I don't condone, but he would want me to transcribe some information he's jotted down here and there about the experience...
"I had been wanting to share an experience on the weekend in question with some friends of mine but we didn't have quite enough money to get as much LSD as we wanted, we knew someone who had confessed to their blotter paper being DOC, so we decided that if we bought one hit of the DOC and one hit of LSD for each of us, the experience should likely be as strong as the 3 hits of LSD we each wanted...
The experience was definitely more intense then 2 doses of LSD and lasted for at least 16 hours... overall there were several happenings that made this experience a very good one... first of all, the LSD seemed to take away the "body load" or fatigue/pain usually caused by DOC alone, second of all, there was a profound sense of mental clarity and discussions of emotions and relationship-related ties flowed with ease, many issues were worked out between friends...also, and this was the most interesting effect, several of us seemed to gain a partial entrance into higher plane/level of hyperspace as we became aware of external entities outside ourselves, not visually, but empathically, the strongest of these was somewhat agitating and upset two of us, including myself and various points in the night, there seemed to be some very disturbed entity that took interest in us, sending of an energy of malice and sorrow...this did not however ruin our experience in whole as coming in contact with it was very interesting and educational, plus, we were able to cast it off...or at least ignore it, after a while...
Overall, the experience was incredibly useful, educational and fun, something to be tried in the future and an experience that suggests further exploration of combining phenethylamines with tryptamines."
There are many profound and important things in life.... I just happen to think that most of them have to do with serotonin.
