That's 500ug, or about 5x the standard "introductory" dose.
I loved peaking. That is, total ego death. Just being there. And the visuals, of course. Totally internal, with the external world just gone. It was like dreaming, except far more intense.
I would typically trip when the moon was full. I'd start in the late evening, with my usual beer or two and some marijuana. And then, just before falling asleep, I'd eat the LSD.
So I'd wake up peaking. And then spend a few hours in bed, "meditating". Eventually, I'd come down enough to shower and dress. Have a mug of ginger tea. Maybe a snack.
And then, a couple hours before dawn, I'd set out on my bicycle. Typically riding toward the setting Moon. I'd often end up at a small park on the west end of a large lake. So I could watch the Sun come up across the lake. Distant flocks of ducks made a trippy sight, skimming across the water.
Then I'd come home, eat, and sleep for maybe 15 hours.
A more detailed look: Most Buddhist traditions frown upon personal demonstrations of achievements and frown upon talking about personal achievements openly without a good reason.
Giving a closer look, a Theravada teacher might talk about their achievements to let students know if they have questions about those topics they have someone they can go to and ask for help.
But eg, on the Zen side of things, it's unheard of for teachers to talk about achievements.
On the other hand, Buddhism openly gives names for states and achievements, so people privately can talk about it and get help from teachers. This vocabulary is explained in detail, and can be used to give you an idea of what the experiences while meditating are like.
Brain scans today show that magic mushrooms and jhanic meditation both light up the brain in nearly identical ways. This implies heightened meditative states are closer to magic mushrooms than lsd.

You also have to factor in that street drugs are all over the charts as far as consistency in the dosing and the person you replied to may have been consuming a fraction of what they thought they were (even humidity and handling can reduce what is there).
But I had a steady high-volume supplier, and bought for resale. So I'd carefully test stuff before buying. I'd start with half the recommended dose. Then, a week later, a full dose. And then, a week later, 2-3 doses.
So what gave me a "standard trip" I considered 0.1-0.2 mg. And when I say 0.5 mg, I mean 3-4 times that.
I worked in a biochem lab, and so stored my LSD under vacuum at -70 deg C.
