Lysergamides The LSD testing thread

[doofhard]

The liquid i've seen under blacklight glowed very impressively when it was dropped on my hand, but certainly not yellow, a bight purple.

I tripped off my cake

 

[Twip]

Could one drop a hit of blotter into a little bit of water, swish it around, and place it under the blacklight to see a glow? Or is that not enough to be effective?

 

[Akoto]

This is an old post but its very relavent to me right now.

This black light test seems to be the most practicle for me (as i have a good one), but the stuff I will probably need to test wont be in liquid form. How can i get it out of the blotter to test it out? and if it turns out to be the real deal, will i have to get a new thing or can i just drink the extract?

 

[Akoto]

cant anyone shed some light on this?

And if the trip lasts more than 8 hours, it's not LSD.

thats the dumbest thing ive ever heard! of course acid lasts 8+ hours, in fact the more you take the longer it lasts, ive tripped for 14 hours on acid. And on top of that it has taken up to 2 hours to feel threshold effects, but this was most definitely acid.

This test only works for liquid, blotter won't have any effect due to the paper involved. If it is good lsd, a drop of liquid on a sugar cube will glow 2x-4x brighter than the sugar cube itself (and it glows bright blue, not yellow). It is really easy to tell on the sugar cube because the lsd will give a noticable flourescence beyond the typical glow white objects (like the sugar cube) give under UV light.

I beg to differ because I've seen acid glow on tabs. You can usually see it in streaks going from lighter to darker pending on its position on the blotter. Or you can see where the lsd was dropped if out of a dropper. And as with sugar cubes you can most defintiely see the lsd glow as well.

I'm near positive that we had a huge influx of of 5-MeO-AMT sold as LSD a few months ago in the area that I live. It was on almost cardboard thickness paper with no markings. Didn't feel like acid at all, there was no clear peak or point where it suddenly hit me, just kept coming up every few hours till pretty late/early when I fell asleep, didn't really trip that much either just alot of morphing. After a while the dealer stopped selling it and said he would only sell it in bulk..

 

[TAPPER]

Judging by the length of time tripping or how fast is came on is bs. As said by others, LSD has hit within 10 minutes or up to several hours (this is usually when one re-doses and gets spanked by a heavy duty experience). It has also lasted well past 8 hours on as little as a hit or two.

how about leaving some out to dry on a mirror or such, then inspect the remaining crystals? ( i know its going to take more than a few drops to see anything)

lsd is a fragile molecule, maybe a little "abuse" to a small qty and then human test?

 

[moecat]

I believe a lot of these subjective impressions add up to significance. Even an analysis on an instrument is often open to some interpretation. Thus rapid onset has some merit.

I don't believe fluorescence under blacklight is too trustworthy. After all, the tetrahydrozoline in Visine shows this fluorescence. I believe 5-meo-amt would also, but more yellowish than the bluish fluorescence reported for LSD. Again, these are subjective observations, probably no more trustworthy than the others mentioned in this thread.

If possible, doing TLC would give one unique characteristic of LSD....that being, the co-existance of iso-LSD. If you can resolve two fluorescent spots, this is indicative of LSD. All LSD in solution tends to an equilibrium with iso-LSD at a ratio of about 9:1.

95% ethanol with silica gel TLC plates works for this separation. It can indicate the presence of LSD at a concentration equivalent to 25 drops/hit....so I suppose a concentration of about 2-4 ug/drop.

As far as colorimetric reagents, p-dimethylaminobenzaldehyde reagent in it's various flavors (van Urk, Ehrlich) certainly would show a color with either LSD or 5-meo-amt. It's possible that a more selective reagent would be simple ninhydrin. It would perhaps show a greater reaction with the free amine of 5-meo-amt than a lysergamide. Without testing this, I can't say for sure.

 

[Coolio]

I am bumping this because this is one of the most important harm reduction concepts that has yet to be resolved in the psychedelic drug scene. 5-MeO-AMT has become the de facto replacement for LSD blotters the past few years, and nobody has come up with an accurate and conclusive field test. Both moecat and myself have given a long list of suggested tests, and a combination of two tests that produce markedly different results for known qualitative samples of 5-MeO-AMT and LSD is sorely needed. I would work something up if I could afford to, but I am in saving my money mode right now. Is anyone out here willing to figure out what reagents Joe Drug User would need to quickly determine whether some liquid or blotter he just bought is 5-MeO-AMT or LSD?

 

[Beenhead]

I have some TLC Chromatography paper from my Lab used for ID of Amino Acids. I believe what I have is silica gel type. Does anyone know what the R sub f value for LSD is, or what the migration pattern is supposed to look like? The TEK on ERowid is not for what I have right? Please help!

 

[soul]

LSD has the tryptamine skeleton incorporated into the 4 ring lyseric acid molecule (tryptamine being regarded as an amine nitrogen separated from the 3 position of indole by two carbon atoms. I've included a little pic for anyone who can't visualize what I mean (also shows how lysergic acid is also a 4-substituted tryptamine (a la psilocin) although the 4 position is substituted with a carbon atom in LSD (part of C ring), rather than an oxygen as with psilocin.
In diag, tryptamine skeleton is in red

it's funny,

as i started reading this thread, i wondered if
fastandbulbous would clarify on this with subject with the
ownage, and sure enough, this person fails to dissapoint.

 

[Beenhead]

Just for info sake, I placed several drops of ethanol solution containing unkown drug extracted from blotter paper onto chromatgraphy paper. let each drop dry before reapplying. Put a small amount of ethanol in the bottom of a plastic cylinder, sealed to get a saturated atmosphere. Then placed the paper in with the spotted side barely touching the ethanol, and leaning diagnolly on the wall of the tube. Sealed until the alchohol migrated up the paper. Took the paper out of the ube and alowed to dry. I could see two distinct spots had migrated up the paper, right next to each other. They both glowed under the blacklight.
Positive TLC for Indol. Not 100% but atleast I know its probably not DOC or DOI!

 

[J. Alfred Prufrock]

Nicely done.

You just repeated this observation from this work:

Congratulations.

I have some of the 'controversial' Hofmann blotter pictured here:

http://www.bluelight.ru/vb/showpost.php?p=7371225&postcount=587

and I am uncertain about its identity. Based on my (limited) experience of about 10 tryptamines, PEA's and amphetamines, I would say it is not an amphetamine, it has a general tryptamine feel but does not feel like acid. I've had only one experience though and can't be sure if it's because of me or because of the substance on the blotter.

Is there a low-tech do-it-at-home test that I can do? Some people talked of boiling it, but others said LSD is not all that heat-sensitive after all. Maybe a chlorine-based solution? Would that destroy LSD but not 5-MeO-AMT or other possible adulterants?

Also, are there more salient characteristics of the 5-MeO-AMT trip that would help distinguishing it? I have no experience with it but my trip on the Hofmann blotter was spent on the border between sleep and waking, in a pretty confused headspace. Is 5-MeO-AMT more stimulating?

 

[Solipsis]

How many hofmanns have you taken yet?

 

[jamaica0535]

There is a reagent test for LSD....

Ehrlich reagent, i belive it is...

Although i imagine if the wikpiedia for it is correct, it changes in the presense of indoles, so other tryptamines would probably react....

Its more for testing whether or not blotter is just paper, or actual blotter...

 

[RigaCrypto]

Only one and as I said, the experience might not be representative. I'm going to try more, but I also want to test it.

It does not discriminate between LSD and 5-MeO-AMT (or other indoles). I am confident that what I have is not an amphetamine.

If the liquid is tastless and a 1/10 of a ml would be considered a "hit" and has noticable psych effects, i would assume LSD... As not a lot of other psychs will be able to have enough chemical in that sort of ammount to do a whole lot while being tasteless....

Length of experience could play a role in what it is, you said a friend took it correct?

Of course we are not really supposed to speculate on what it really is....

You could do an evaporation in a dark space. If the amount of residue left is something on the order of a milligram, which should be hardly visible at all that greatly narrows the possibilites down... Not a lot of drugs are active in the submilligram range... Salvia, Bromo Dragonfly, LSD, various fentanyl derivatives, ALD, threshold dose of a DOx.... ALD might as well be LSD, doubtful it would be salvia, if it has no taste that would rule out the DOx class as well as your being sure its not an amphetamine...

It wouldn't be unheard of to put 10 drops of LSD into a vial... most people put vial drops in peoples mouths or drop it on candy or sugar cubes for later consumption but liquid LSD is not that uncommon...

It's blotter, not liquid, and this batch of Hofmann is notoriously bitter, though this may have other explanations. Also, the tabs are 8x8mm.

From what I've seen on Erowid, the timeline of 5-MeO-AMT generally matches that of LSD.
