LSD is less linear. Increased focus, energy, visual acuity, but you won't get stuck organizing all your documents for the 12th time like on amphetamines.
I actually take both substances together, and find that the synergy is superior to either one by themselves. But it takes real commitment to have such a dosing protocol because most "normal" individuals do not/would not understand it
The trip logic works like this. Your brain-organism evolved in the context of our 4-dimensional universe. Psychedelics tend to alter patterns of perception in a way that releases a flood of images. Your brain itself is a hyperdimensional problem solver so when flipped on its head with DMT you can experience really fascinating hyperdimensional universe-images.
As to revealing anything of the real structure of existence...nothing can be said. They reveal the structure of our brains, which themselves are a micromodel of our universe (compare the branching pattern of the brain's neurons to a zoomed out picture of the universe to the branching pattern of a tree to the lichtenberg patterns of lightning to the branching pattern of mycelia...they all tend to converge to the same fractal).
DMT can never give you "real" knowledge of the universe...but neither can any kind of experiment. All of our observations are really just images formed via some form of interaction. All you can really do is get hunches, and hope that as a prt of the universe, its greater structure is reflected in the microcosm that is you.
If I was forced to guess, I would say we exist in a 4d pocket universe within a fractally infinite hyperdimensional bulk multiverse. Universes are constantly being born and dying, with the net effect that the fundamental nature of reality is timeless (time is a psychological abstraction). But that brings us no closer to true understanding, which is probably an illusion anyway.
Reagent tests tests for presence, not purity. They're just a way of ruling out if you for sure don't have the compound you're looking for. However, you will never get any data on purity, and with multiple substances on a tab you will be hard pressed to identify the substances.
A little knowledge goes a long way, however. Tabs can only fit hundreds of micrograms to around a milligram (maybe a few mg's) on a standard sized blotter tab. This narrows down the # of potential active compounds massively. Also, LSD is active when swallowed immediately but nbomes aren't. So for a knowledgeable user it's not hard to avoid nbomes, but you will never be able to find out how much LSD is actually on your tab.
LSD should never separate in solution. It should always stay evenly distributed, and liquid is an ideal long term storage form anyway.
For testing, the only effective technique is GC/MS. But there is only one lab [REDACTED] knows of, which is the Spanish lab Energy Control. Unfortunately they are not always competent and often make routine errors in analysis.
[REDACTED] has never tasted anything but paper on tabs, but some claim a metallic taste when there is none. The best protocol is to swallow the tab, in which case nbomes will not have an effect (they must be sublingually absorbed). There is little reason to take LSD sublingually although it is quite common among recreational users - which is again silly because if you swallow you can guarantee that nbomes won't affect you
Without gc/ms you just don't know what's in your tab/liquid/etc. That being said iirc it takes milligrams to OD on fent which means you'd be pretty safe with tabs. Liquid is another story.
[REDACTED] acquired LSD tartrate, made solution w/ everclear, and then diluted it such that one sip is roughly 4-8ug based on volume. That's the only real way to microdose yourself, although you could cut a tab into 20 pieces (depends on the lay but a skilled lay is evenly distributed. An unskilled lay will have massive hotspots and thus one would need to dissolve the tab in a solvent or cut it into n->infty pieces)
anecdotal, but I strongly believe it makes you actually sharper. Not everyone needs more dopaminergic stimulation though (I certainly do to function in society)
Hey, I don't have any real evidence to add, but I would often read articles about LSD microdosing and assumed it was bullshit.
After trying it on myself 5-10ug / day for 6+ months, I think it's been incredibly beneficial.
The crux of it is that if you drop a full tab and pay attention, you'll notice LSD is extremely stimulating - far more than psilocybin. It has a very high level of dopamine receptor activation, which is why even 10 hours into a trip I would notice how different the quality of my attention was - in essence, it was far easier to simply be aware of what was going on.
(Note I have adhd-pi so that's part of why I think microdosing works for me)
In short, a microdose gives the dopaminergic stimulatory benefits, without being overwhelmingly twitchy. It produces a less linear style of thinking than amphetamines (adderall/vyvanse/desoxyn), but still increases general energy, focus, quality of attention etc. Colors feel a tiny bit sharper, visual acuity feels slightly enhanced, physical body control is significantly enhanced (I have far better posture and general neuromuscular control).
Obviously this isn't rigorous evidence, but hopefully it gives a general idea of why one would microdose.
One final thing - 25ug or even 15ug is far too much. IMO 10ug is the upper limit of what would be considered a microdose. My preference is 4-8 ug (obviously dosed as liquid)
IMO most "stable minds" should be messed with. Stable is relative. Most minds are "stable" in that they are crystallized into arbitrary activity patterns. This is why deep personality change is extremely difficult without psychedelics (you need a transformative experience, psychedelic or otherwise, to change)
Not the one you asked, but psychedelics inject a ton of entropy into the system, allowing you to break out of the "bound states" humans tend to get stuck in.
Taking shrooms pretty much rewired my value structure from the ground up. I went from caring about traditional things like a good career (therefore social approval and everything else), to valuing spending time in the sun with good friends more than our usual ego-centric living patrerns.
LSD is great for the visual/aesthetic experience - it's so stimulating and kinesthetic - but it leaves your mind a little more intact.
DMT is a really interesting and profound psychedelic, and one that is massively misunderstood and, IMO, unfairly judged. Doing large amounts of DMT improved my ability to visualize hyperdimensional systems, and gave me (in my subjective opinion) a better understanding of the nature and structure of existence
