Yellow go-go ?

[Ondatom]

A friend of mine recently aqquired some meth that is very Yellowish in appearance, and as well as it living up to all expectations one could have about meth except for the fact that it when smoked it has a very strong taste ,almost like a sweet chemical sought of taste (if there is such a thing) someone suggested that it was probable that it had been pure amphetamine converted to meth(due to large amount of bikies in swix's part of the world, this seemed reasonable) but swim seems more to think that it is more likely some sort of leftover Gak that was not cleaned properly in the pill stage. This is not the first time i have seen such meth as im sure any other Oz bee's would have seen this too. Anyone who could offer any answers to such vague info would be appreciated .thanks

pure amphetamine converted to meth

?? huh... what do you mean by this?

leftover Gak that was not cleaned properly in the pill stage.

Maybe, but most crap stops it being made in the first place.... you probably better to re-crystalise it... look on rhodiums site for info how to do this... the yellow is more than likely left over shit from rxn..

[unionpacific]

Sounds over-acidified, and/or cut.

[sublevel]

the go go that is yellow have seen it in OZ
it has the smell of reaction fluid before it is based and is slightly moist most of the time

I had always thought that it was reaction fluid filtered of RP then evapped for crude salt

Just an opinion, but it is very dirty gear so be careful

[ChemoSabe]

If it's over acidified this can easily bee removed by placing the stuff in an unbleached coffee filter and then pouring a small quantity of chilled acetone over it and gently swishing it back and forth as the acetone drains throught the filter.

Save the acetone and evaporate later on a rainy day for a dirty bump or two.

For a real improvement to the street garbage see this thread and follow the links to the worlock thread.

Swim once aquired some yellow sludge and it was putrid gear!!
Swim experienced a very dirty jolt upon injection of 250mg, but it was quite a strong high. However,it made swim ill the next day and he was really scattered!
Take it from me mate, you want to steer clear of that shit, find something better!!  
I suspect an acetone rinse may solve the colour but it wont reverse careless production and dirty precursors!!

[CharlieBigpotato]

excess hcl is the obvious answer, and easy to remove...however, swim once dreamt of some pristine gear that was absolutely sparkling, and put it into a tiny zip-lok baggie, and it started to get yellow over the course of a few days.
after about a week, it was extremely yellow!
didn't effect the quality at all, yet swim remains baffled as to what had occurred, and never saw a repeat performance.

had to assume it was something in the plastic bag that caused it.

[Ondatom]

is over acidifying the reason behind the strong taste too ? and will an acetone rinse rid it ? cause the taste is the real killer ,the looks i can handle . thanks for the info so far everyone

[ordinaryguy]

either too much hcl vapor was passed through the np/freebase solution or during titriation too much hcl was added dropwise. one solution would be to dissolve in alchohol then evaporate with a acetone crash and recrystallize but a little yellow in my opinion is typically ok. if it doesn't leave a heavy residue in the pipe I wouldn't be too concerned. this is refered to as over-gas in my neck of the woods. good luck

[Ondatom]

swim just gave it a cold acetone rinse and watched as the yellow washed away... swim's go-go is now just off-white . Cant get a pipe till morning but swim is praying the taste went with the yellow.

Do a second rinse for purity- usually one is enough- but that's only done if the crystals were white to begin with.  Then -make sure- you've completely dried your product before use. If you have access to a vacuum pump- dry under vacuum for 1-3 hours. (consistent weight)

[place]

AFAIK will GoGo which not have been cleaned properly turn yellow. Also, wouldn't idoephedrine turn yellow after a while when exsposed to air?

[Aurelius]

If you want clean material- freebase, use column chromatography to separate the components (also gives several usable precursors from the byproducts), then recrystallize from methanol or ethanol- let dry overnight (or a couple hours if under vacuum).

[xaja]

You don't need to get carried away with this. Just do what ChemoSabe said, coffee filter + acetone. Air dry for 10mins, fuck the vacuum pump.

If you want to err on the side of caution, dry the acetone first with epsom salts (UTFSE for how to do this).

[peregrine]

I've had yellow meth on many occasions and it seemed alright to me.But then again I don't smoke the shit.Some of the best stuff I had was yellow.

[ChemoSabe]

I'd also say that Worlock's newbee friendly recryst recipe is only recommended if you've at least got a gram of material to work with. If the shit is cut (and if it came from the streets it alsmost surely is) you're going see a marked drop in what you get back from it so you may be disappointed at the quantity but you won't complain about the quality.

The mistake most make when first trying this recipe initially is adding too much alcohol so it pays off to not put all your gear in at the start but so save a bit to add after you're certain the alcohol balance is correct. If you way overshoot the amount of alc usually it's best to evaporate the whole thing in a bake dish and start again. Trying to boil it down often doesn't work becasue the acetone will evap first but most of the acl will stay til the end.

(Worlock: "Re: ReCrystalizing Chilli", Stimulants) you'll see that Worlock was helping out in a case similar to your own.

Don't read anything racist into this but Jacked used to have a saying concerning clean gear that went "if it ain't white it ain't right"

[Aurelius]

Have you seen his gear though?  I like clean stuff, but wow!

[Ondatom]

Swim found he was losing a bit of wait so he kept using the same acetone(so he would have less to evap at the end) on each group of rinses(total amount to be rinsed was seperated into 5 even amounts) Was fresh acetone needed for each one ? and will the meth benefit from a second rinse ?

[ChemoSabe]

It's a better bet to always use fresh tone.

If it's still yellow then rinse again as needed.

It usually doesn't take a lot of acetone. Swish around small amounts rather than flood it.

Dries nicely by folding over the top of the filter with a good crease and then blow dry with hair dryer.

Don't throw out the used tone though. It's carrying a small degree of goods.

While on the topic..

Does anyone know what sorts of impurities acetone typically contains? 

Reducing >200mL of it after psycho-serial washings (for 'floaters') yielded orange gaak-looking crap that smelled like used car tires-- even slightly sulfurous.. But now it is noticed that even unused acetone has this aroma.  The reduction of such smaller quantities only leaves little white outlines and a little liquid assumed to be water-- far short of orange sludge.

Anyhoo, Is this normal?  What sorts of trace oils/minerals could there be in such assetone?
