This was perhaps the most intense experience of my life, happened over 
a year ago, and I still have difficulty recounting or even thinking about 
it.  I will do so briefly here.
     At Palenque 99 with a group of about 9, mostly strangers who knew one 
another only a few days.  Two members of the group had taken ayahuasca in 
Peru.  None of the rest of us ever had (successfully).
     The "A" part is the "Natural Herbal Relaxant" or MAOI which was 
supposedly 60mg harmaline freebase with 20mg Banisteriopsis caapi extract in 
large brown pills.  The "B" part is the "Natural Herbal Tonic" and is 
supposedly 10mg 5MeO-DMT.  The man I got it from says he takes 2 of the "A" 
and 4-5 of the "B."  Thinking that I'm in safe hands with experienced folk I 
elect to take 2 and 4, respectively, amounting to about 120mg harmaline, 
40mg B.c. extract, and 40mg 5MeO.  Now, in retrospect, this was WAAAYYY too 
much, especially for a first attempt, in the jungle, in a group of 
strangers, etc, etc.  Lesson learned, the hard way!  As noted in by Ott 
today (via Earth), 30mg of 5MeO is orally active ALONE, with 60mg harmaline 
+ 10mg 5MeO the threshold activity for the combo.  Enough said.  I suppose 
my justification then was that I had smoked up to ~30mg of 5MeO and lived 
(barely) to talk about it.  Ahh the follies of youth!
     I took one MAOI pill, waited 10 minutes, took the other MAOI pill, 
waited 15 minutes, then took the 5MeO.  I was told later that the dosage is 
worked out to be taken simultaneously.  Funny no one made that indicated 
prior to the disaster.  As those of you who went to Palenque this year can 
attest to, these things happen with new compounds.  I should note that not 
every participant took the same dose, most took less than me, though a few 
took as much.  No one took more (fortunately).
     I do not have an accurate account of time passing so I shall summarize 
the effects.  First I was getting very little, if anything some eyes closed 
images.  I did some chanting and singing and the two experienced men brought 
out their "mesas" ("table" of power objects) and one of them retched loudly. 
  Over the next several hours, a couple of participants retched.  There was 
then a dramatic sequence in which one man became the Christ-figure of the 
group, having a very difficult time of it and requiring the whole groups' 
energy and attention to get him back.  I consoled his older brother saying 
that "similar things had happened to me before."  Well, I must have 
projected that one!  [if you look hard enough you can find his account 
online].
     Soon after we had brought our friend down I took the role.  My memory 
of this is fuzzy, but I remember forcing myself to retch as I felt I was not 
getting full effects.  This may have been about +2 hours.  I remember 
feeling like I was vomiting the universe, snakes, wormholes, then everything 
spiraled out of control like my high-dose smoked 5MeO tryps.  I remember my 
female partner at the time who I was travelling with rejecting my advances 
(in my mind merely sharing a hammock).  Apparently she did not want her trip 
to be invaded on.  By this point I was totally lost in the void.  I had 
taken up our previously troubled friend's experience, my own, and I was 
surrounded by nothing and no one familiar.  Apparently at some point I bit 
someone's finger, and I remember vaugely someone trying to touch my head 
which I apparently snapped at.  The man trying to talk me down I could not 
even recognize and clearly thought he was someone else.  I also remember 
trying to talk to a man I knew was multilingual and being extremely 
frustrated that he could not understand me (something like a frustrated 
frightened child who is trying to communicate).
     What I really remember next is being taken to my room where the floor 
heaved and I heaved with it, time and time again.  I finally slept, but not 
really.  The next day on the way to breakfast I saw a brightly colored snake 
and had the urge to pick it up then decided against it.  I dealt with the 
people in the group for several hours and could not focus on lectures for 
the rest of the weekend.  Finally a group MDMA session a couple of nights 
later gave me some grounding.  Also a chewed Salvia session in a Veracruz 
garden helped some integration as well.
     I still don't really know what happened that night.  I only know that 
5MeO with MAOI is the strongest thing I have ever experienced, stronger even 
than NN with MAOI.  One day I may do it again, at half the dose, to see if I 
can find my way back to a little of it.  If nothing else it is a lesson to 
all of us who were there and who were not.  Don't think you're a hardhead 
and then blow the top off your head and hurt others.  It isn't worth it, no 
matter how rare the material.
==================================
I hope this is of use to someone.  When I get the nerve up, the next stop is 
Toad Venom.  I prefered all of the above experiences to DPT or 5MeO-DIPT, 
though the latter (at 10 and 16mg) seemed like a no-strings-attached, mild, 
fun, recreational drug.  The former (at 40mg and 55mg snuffed and 200mg 
orally) was interesting, highly visual, and sensual, but too-short lived for 
my taste (2 hours for snuff, 3 for oral).

Anyway,
Be Goode and Be Safe...
