yes, freeze percip is not what you do with the xylene....
Fumaric acid saturated dry acetone is added to the xylene pulls drop wise, and salts trop out of that, the salts art then scraped up and combined with about an equal amount of sodium carbonate (just bake some bicarb of soda at the same time as you bake the epsom salts to dry the acetone).
Next a tiny bit of water is added, just enough to make a nice sloppy paste, and mix well... you have now added a base to the DMT, and it is now in freebase form (although stuck in the paste).
Next you will stir in a tiny bit of normal dried acetone (not FASA, as this will only add more of a fumaric acid deposit).. roll off the acetone and collect in an evap dish by pouring or sucking out with a pippette.
Repeat at least 5 times and collect all in one evap dish.
Evap the acetone (this is why its important to use dried acetone as any water in the acetone makes for gooie juice that takes forever to dry)
The above step works because the DMT freebase is disolveable in acetone
The product you get now is called jungle spice as it also contains some other alkaloids form the mimosa, this stuff is very strong, and you will be able to blow your roof off wit probably a 3rd or less of your normal dose... This stuff is a little strong for you still till you are more experienced.. I suggest you smoke a bout 25mg of normal freebase DMT very day for about a week to get an idea of the scope of possible experiences... You see, every time tends to be diffirent in such a radical way to be totaly unpredictable. These small doses will build up your confidence ans liekly show you some of the realy pretty fractal type visions the drug is more known for, I don't think one should aim to get fully transported into hyperspace before you get accustomed to smaller doses first. It is an extreme experience, which you would likeley only apreciate in hindsight, with a lot of time between you and the event.
At this point I would suggest you seperate the jungle form the spice by adding a bit of naphta and placeing the dish/cup in a heated bath (proabably about 50C max) until the DMT melts into the naphta, (a small layer of jungle will cling to the bottom, pour over into freeze percip dish, and stick it in freezer for a normal FP.
Now you should have freebase DMT that is more suitable to your weekend warrior than your shaman types.
Next you can go more crazy by takeing those crystals and disolveing it into a small bit of heptane also at a slightly elevated temperature.
This is allowed to gradualy cool over several days, the slower, the the bigger your crystals get... these are those glass pieces of DMT.
Now you can see why I suggest people start with normal Naphta teks, to get into the swing of things, before learning to maximise yields.
P.S. if you ever want to smake DMT on your own, make sure to lie on your side, in a first aid position, just in case you get what hapened with your GF when she exceeded her safe dose. Which is dependant on body weight.
I'd hate for anyone to become the first DMT fatality.
