adderall or dexamph - chemical or physiological ways to determine?

[nex]

Hi,
i got a white powder and it seems quite pure.
came from a reliable source which always got sth better than street quality.

i was told it's dexamph and later he said it's adderall directly from the factory (?!). sounds like random shit dealers tell you, but he is not a dealer and quite trustworthy.
im 100% sure it doesnt come from crushed pills, but he said that there are perhaps very small amounts of pill fillers in it.

i'm dosing it with a 2mg/drop solution in a 1g/30ml bottle. used a 0.01g scale.
i have no comparison to pills with a known amount of amph, but it seems that even low amounts/some milligrams of my stuff do what they should.
so i conclude there is not much filler in it.

tl;dr
is there any way to determine wether its pure dexamph or mixed salts like adderal or even racemat?
chemically or physiologically?
are there distinct signs/side effects of L-amph i can fell/observe?

I tested the stuff many times, mostly low dosage sometimes higher.
it doesnt give me a lot of euphoria even with higher amounts - doesnt make fun to party with this stuff. (which is not my aim)

I know that L-amph stimulates the PNS and i'm tryingh to find out which pns effects are caused by l-amp.

ps: hope it's right in add, i'm searching for a scientific answer

Testing for amphetamine: Maruqis, Mecke, Mandelin reagents.
Differentiating methamphetamine from amphetamine: Robadope, Simons reagents.
Differentiating (+) from (-) amphetamines: use a polarimeter with a 1% methanol solution I guess?

There are also some USP test methods you can look up but they involve potentiometric titration with perchloric acid. Other handy metrics to look are are water/other solvent solubility, total freebasable alkaloids, total residue on ignition, melting point, crystal size/shape.

Pretty impossible for the lay-man to tell racemic amph from 70% dextro from 100% dextro without having had previous experience with all 3, I would say, so don't use bioassay to judge what you have. There are too many stims that are "close to" amphetamine in effects.

thanks, this is what i expected.

got to find someone with a polarimeter :D

You could make one %)

I'm not sure even that would work with adderall though:

1/4 dextroamphetamine saccharate
1/4 dextroamphetamine sulfate, USP
1/4 (racemic) amphetamine aspartate monohydrate
1/4 (racemic) amphetamine sulfate, USP

Is it L-aspartate? What's saccharate, I guess it's chiral too? I'd have thought it would be impossible to predict the optical rotation.

 

[sekio]

Saccharic acid and L-apsartic acid are both chiral
Saccharic acid -

Pretty sure all the chiral sugars would make it pretty difficult too, maybe it would be best simply to do a reagent test for the presence of carboxyl group and sugars?

 

[sekio]

Just run an acid/base speperation (turn it all to phopshate or whatever), or do the math and account for the specific rotation of those 2 chiral compounds.

Other chiral compounds that might be in it include msg, sugars, ephedrine.

Crushed Adderall shouldn't be a white powder anyway, if memory serves the beads are orange.

They are orange.

I just realized that with all the binders in it you probably wouldn't be able to do a simple reagent test unless you're testing for a colouring agent or some sort of XR related polymer. My thinking it you either got some non-pharmaceutical amphetamine or some RC. Also, given the fact that your dealer has no clue what it is we're not going to figure this out with out doing some non-bathroom chemistry.

The simplest test is a "dosage test", if its crushed pills then 20mg of raw powder wouldn't do much. If its raw amphetamine salts, then you'll feel it. Advanced? Nope, but we don't really do "what's in the bag man" style threads either.

If it's a white powder active at 2-5mg, water soluble, non-deliquescent I would be inclined to suggest it's pure amphetamine phosphate. If it sucks water out of the air like a cheap whore then it's probably the meth hcl. Chiral purity could be figured easily by polarimeter.

This is almost certainly a lie. It's not pure dexamp coming from a major pharmaceutical company; it's very hard to get that outside of a strictly-controlled research setting. There's a chance that it could be stolen from a lab, but much more likely that it's just good quality amphetamine from a clandestine manufacturer. The fact that he mentions 'pill filler' is curious, so it's even possible that he just extracted amphetamine from pills.

Or it might even be a generic stimulant research chemical. There's no way to know without testing it.

Normally, I would consider this very bad practice, but you could certainly try tasting a small sample of your powder. Since they give adderall to little kids, they actually make it sweet. The amphetamine bonds with saccharate and aspartate. Both these anions taste sweet. Tasting would instantly tell you if you have "adderall". Proving the presence of pure dextroamphetamine or another research stimulant would probably require reagents and/or lab equipment. On second thought you could freebase it and check the melting point and compare it to reference values in the Merck index to attempt to identify your substance. However, tasting a small sample of your powder offers a simple way to disprove that you have adderall if it doesn't taste sweet, and offers evidence that you have adderall if it does. Effects wise, levoamphetamine has only peripheral activity, so a sample of adderall would have less CNS activity than a sample of pure amphetamine sulfate. If you have pure amphetamine sulfate, then you could run tests to see if an identical amount of your powder has comparable effect, although I do not recommend this if you don't know what you have.

The NMR spectrum for an enantiomerically pure product will differ from the racemate. This is by far the easiest method, but (its a big but lol), if you don't have access to an NMR instrument its not of any help. I like Sekio's idea of using a polarimeter, because a crude polarimeter can be constructed from commonly available materials.
