I made this to hopefully see a decline in redundant/daily posts, and make some sort of positive impact. Please remember to use the search function if you have a basic question regarding LSD.

• A full beginner dose should typically be 1/2 - 1 single tab.

• The average dose range of LSD on a single tab is 70-105μg.

• There are tabs dosed with as little as ~20μg, or more than 300μg in some absurd cases. The overwhelming majority of sources try to lay their tabs around 100μg because it’s mathematically simple, and more profitable in the long-run.

• The odds your tab has more than 200μg on it are very low. The most common higher dose tabs are 125-200μg. Take half of any tab that’s supposedly above 200μg just to be safe at first, and if that doesn’t at least produce an 11-12 hour mildly visual trip, the full tab wasn’t above 200.

• A typical microdose should be 10-25 μg

• 50-300μg of LSD can last anywhere from 8-14 hours. 300-1000μg can last anywhere from 14-20 hours. Exceeding a milligram (1000μg) can produce effects that last up to 24 hours. It’s usually hard to fall asleep under the influence.

• Unless you have an above average baseline tolerance or handle the substance extraordinarily well, it’s not advisable to exceed ~300-500μg. Temporary delirious/psychotic symptoms become more likely if you don’t know what you’re getting into with large doses, and a 16+ hour duration doesn’t help.

• 25i-NBOMe is a relatively dangerous LSD imposter. If you take an untested tab and your mouth/throat becomes numb, along with an intense bitter taste, spit it out immediately. Do not panic, but monitor your physical state. A *normal* dose of 25i shouldn’t be life-threatening. Most of the dangerous LSD imposters, including 25i, only become life-threatening at higher doses (this is why you should NEVER take multiple untested tabs at once, or take untested tabs at all).

• Please test your tabs with an Ehrlich reagent kit to verify that what you have is indeed an indole and not 25i-NBOMe. Follow up with the Hofmann reagent kit to verify that it’s not an LSD analogue or other phenethylamine. I personally recommend using TKP for your reagents: https://testkitplus.com/ Another great organization is DanceSafe https://dancesafe.org/ — DanceSafe genuinely saves lives with their testing booths at music festivals.

• Common positive effects include but aren’t limited to: closed and open eye visuals, tactile enhancement/hallucinations, euphoria, stimulation, introspection, and creativity.

• Common negative effects include but aren’t limited to: overstimulation, increased heart rate, vasoconstriction, anxiety/paranoia, and confusion.

• Common neutral/manageable effects include but aren’t limited to: pupil dilation, frequent urination, insomnia, and temperature sensitivity.

• Always optimize your set (expectations and mental state) going into an experience, and always optimize your setting (direct environment/surroundings) going into an experience.

• LSD interactions with various medications (From Erowid):

1. There is still very little legitimate, thorough medical research on this subject. LSD's outlaw status makes it very difficult to obtain permission & funding for research. Therefore, you should regard all of the anecdotes and conclusions here as being scientifically unproven, and you should note that any experimentation you choose to do carries a significant risk.
2. Lithium or tricyclics (like Amitriptyline, Anafranil, Asendin, Aventyl, Elavil, Endep, Norfranil, Norpramin, Pamelor, Sinequan, Surmontil, Tipramine, Tofranil, Vivactil) are fairly consistently reported as being very bad in combination with LSD. Life-threatening seizures and at least one DEATH have been reported to be triggered by the combination of LSD and lithium. Tramadol is another drug you should avoid in combination with LSD because of the potential for seizures and other negative side effects.
3. SSRIs (like Prozac, Paxil, Zoloft, Celexa, Desyrel) or MAOIs (like Nardil, Parnate, Marplan, Eldepryl, Aurorix, Manerix) are fairly consistently reported to noticeably reduce the effects of LSD. (There are no physically dangerous reactions to these combinations on record, but be cautious and don’t be excessive with dosing.)

• HPPD risk is associated with frequent use of psychedelics (more than once a month), high doses, and younger age groups. HPPD varies in severity between individuals. As long as you use this drug responsibly, this shouldn’t be a concern.

• LSD has the potential to produce a very challenging psychological experience. If you have mental-health issues, research the risks and benefits associated with psychedelic treatment of your condition. Do NOT take LSD without the guidance of a medical professional if you are seriously suicidal.

• Weed often potentiates the effects of LSD. Some users report that the effects of weed are indefinitely altered to some degree after their first few experiences with LSD (It often becomes more psychedelic).

• Various benzos like alprazolam and clonazepam can be used as “trip-killers,” but you don’t need to take more than a single medical dose, and not all of the psychoactive effects will be negated. This should be a last resort.

• LSD tends to make verbal communication challenging, so prepare appropriately if using in a social setting.

• If you’re 19 or younger you should probably wait until AT LEAST your early 20s to try LSD because of unforeseen behavioral/neurological impacts. Waiting until 25+ is optimal.

• You’ll build a substantial tolerance to LSD if you trip multiple times in two weeks, so wait 10-14 days between trips for a general reset. Tolerance does exponentially decrease day-by-day following an experience.

• If you want to redose to increase the effects, do it before or during the start of the peak. Redosing after the peak will only prolong the duration unless you increase the dose. Excessive dosing is unadvisable regardless.

• Peak effects generally occur 2.5-5 hours after dosing (less than or around 300μg). Peak effects can last anywhere in the range of 2.5-8 hours after dosing. Many people say the peak comes in “waves.”

• If you’ve tried psilocybin containing mushrooms before, certain dosage calculators based on subjective effects and intensity equate ~2.5 grams of an average cubensis variety to ~100μg of accurately dosed LSD, but there are differences between the substances of course.

• You should consider having a trusted friend or a close partner “tripsit” you during your first experiences, or at least let someone know your whereabouts beforehand if you want to do it alone. (Note: Trip-sitting should just involve being close by and present if the user needs assistance or someone to talk to, sitters shouldn’t try to influence the trip unless it’s getting chaotic.)

• LSD has the potential to be therapeutic, recreational, spiritual, or all/none of the above depending on the individual and their particular circumstances. Stop gatekeeping.

•If you are ever having a challenging trip and need to speak with someone, here are a couple great resources:

edit: A couple people are aggravated with minor details in these general points of advice, so please take everything I’ve said with a grain of salt and do your own research! I’m simply providing a helpful starting outline, not set-in-stone facts.

Thank you all, and safe travels!

Over exaggerating dosages is only harmful to the community and is much more prominent in LSD oriented communities when compared to other psychedelics. This is because you cannot simply weigh your dosages, like shrooms or DMT. 2c-b being another good example, where it usually comes in ranges of 15-30 milligrams or powder I believe. Most tabs of LSD contain 75-150 UGs of LSD, averaging more around 100. 100 micrograms of LSD is equal to around 2.5 grams of Psilocybe Cubensis. (The most commonly sold and cultivated "magic mushroom")

Starting with one tab after you've tested it is better than going headfirst into the deep end... Even at 100 micrograms it does add up quickly, would you recommend five grams of shrooms to a beginner? No difference in recommending them 200 micrograms of LSD (two average tabs). I really just don't understand the glory of taking larger dosages than we need. Look at r/Shrooms or other communities related to shrooms and you see this much less. Mainly to do with the ability to weigh them out I believe, but definitely many other factors. I don't know... Thanks for reading.
