How do you know that the acid is pure? How do mitigate the worry about impurities like the now rampant fentanyl introduced into other illicit drugs? Not saying that fentanyl is likely to be mixed with lsd just citing an example

TL;DR: Buy an Erlich Reagent test kit, they're $20 or so and could save your life. https://dancesafe.org/product/ehrlichs-reagent-testing-kit/

Long Version: So typically it's not really "mixing" or "cutting" with LSD. What is most common with LSD is laying 25I-NBOME on a sheet and selling it as LSD. The same is done with DOX and innumerable other research chemicals. These are both relatively untested research chemicals that produce similar effects but have more potential side effects. They use these because you can (kinda) trick someone into thinking they're taking LSD because it is a trippy experience and you're unlikely to think it was not LSD. The issue with these drugs is that they kill people so one ought test their "LSD".

LSD along with DMT and mushrooms is an indole alkaloid which means (roughly) they have a shape that can fit into a serotonin receptor nicely which is what gives you the effect of tripping. So, if we can test for them we can tell if it's really LSD or some shitty analog.

BUT HOW?

Thankfully there exists a test for just this. It's called an Ehrlich reagent test and you can buy one for about $15. https://dancesafe.org/product/ehrlichs-reagent-testing-kit/

Edit: Additionally, buying online helps reduce your chances of getting some shitty research chemical because: 1. A vendor typically shoots for having repeat customers. 2. If you get LSD that is not LSD, you can leave a bad review saying so. But still get a test kit.

How does one go about finding a reputable (and legitimate) online seller?

You'll have to do a lot of independent research but a good place to start unraveling the thread is the darknet markets subreddit.

pls respond. also interested.

So, this is only to explain how to do so in the safest way. This is not to encourage people to do drugs, buying drugs is illegal. First, find a market. There are many lists of markets with reviews. I think the news site deepdotweb (dot) com maintains a good list. Then find a quality vendor. Most markets will keep track of a vendors number of sales and their reviews. The reviews should be 95%+ positive and you should read the bad reviews. In the case of LSD I'd suggest finding a vendor that sells just LSD. These are typically people who are really into LSD not just drug dealers and your interactions with them will tend to be better because they're often (not always) ideologically motivated rather than financially motivated, as such they often have better prices and service. Your prices should fall between $2/tab and $4.5/tab depending on how much you buy.

Warning: Do lookup how illegal possessing LSD is in your area. Often times the laws are somewhat insane (25 years for 1 gram of material including the weight of the tab). While it is very unlikely that anything would happen to you while buying online (it's kinda hard for the post office to detect 100 micrograms embedded in a piece of paper in a paper envelope) and LSD is perhaps one of the safest drugs to buy online. Make yourself aware of the associated risks before doing anything.

> I was prescribed vyvanse and found they harmed more than helped in the long run

Care to elaborate? I was prescribed Ritalin and wondering about the long-term effects. Peter Breggin[0] who is a known critic of psychiatric meds quoted some research going as far to suggest them lowering IQ in long-term use.

Vyvanse, to put simply, causes your liver to synthesize dextroamohetamine (75% of adderalls active ingredients). Its effects on your body are similar to adderall. Levoamphetamine, 25% of adderalls active ingredients (what causes adderalls body high), supposedly has neurotoxic effects on the brain, lending some credence to that author's claim. Basically these amphetamines cause your brain to eject dopamine. This is contrasted with Ritalin/concerta/cocaine which act as dopamine reuptake inhibitors, preventing your brain from absorbing the dopamine thereby casing it to over produce in order compensate. Based on what I've read reuptake inhibitors aren't neurotoxic, and can actually guard against some of the neurotoxicity of adderall/levoamphetmine.

Just to clarify, you're saying that Vyvanse doesn't have the potentially neurotoxic effects that Adderall has? My doctor prescribed me Vyvanse and anecdotally it seems to be the preferred treatment for ADD these days.
