No tolerance, and yes the dosage was accurate.

I picked “great fun” as a description as a shorthand because, while I could write more about it, it had little to no net positive or negative impacts on my mental health. For the purposes of this discussion, “Great fun” is kind of meant to communicate that the story is neither a warning or a recommendation regarding depression or any other mental health condition.

500µg is an immense dose, unless you have tolerance. Tabs usually have much less than the claimed amount. What was the source and form that makes you think 500µg is accurate? When it's 250µg or more, it's so overwhelming that many people don't have recollections from the trip after some point.

I didn’t write an extended trip report of a massive dose of LSD because this isn’t erowid and the details of the trip itself aren’t relevant. I brought it up as an example to contrast the post I responded to, as my experience was different regarding long-term effects

I was very aware of and confident about the dosage and I had not had any psychedelics for months previous, so tolerance was impossible (also no medication or other drugs etc)

I was just pointing out (mostly to other users who read this) that the alleged dose is immense and would be overwhelming for most people. Wasn't questioning your experience, only asking out of curiosity about the kind of source and form that makes you confident about the dose.

> source and form that makes you confident about the dose

Volumetric dosing from a vial of known quantity.

I believe there is a point after which the higher dosage doesn't change much, but the duration of the trip. I have noticed the same effect with mushrooms (truffles) where basically doubling the dose didn't do much. I'm not even sure it lasted that much longer, because of course you don't take them in a fixed reproducible setting where you could correctly compare stuff.

I think there is a lot of bullshit around those substances, pushed by shamanic type of people who just invent and repeat nonsense to appear unique/interesting.

The "reports" on Erowid, while interesting in a way, are also so full of nonsense that it's largely irrelevant as a source...
