Yep. It can take a bit to find a dose that low enough to not get a full-on buzz while still getting the positive effects from it.

The biggest problem is that psilocybin content per shroom, strain and specific grow is wildly variable. It's better to get a larger batch from the same harvest of the same strain, grind it to an extremely fine powder and then find a good dose. More experimentation is required for the next batch you get. (Powdering shrooms normalizes the amount of active compounds per dose.)

I have only dabbled in microdoses. The main reason is that my trips are always borderline "heroic doses" at around 50mg of psilocybin, with the how strong my shrooms tend to be. Heroic doses get their name for a reason. Synesthesia (full sensory confusion) and near collapse of normal visual processing starts to happen at that level. Needless to say, it takes a bit for my brain to fully process those experiences.

Disclaimer: Even though I have a bit of practice, I have had an occasional rough experience at my dosage levels. Managing emotions in that state can be quite a challenge. All in all, no experience has been truly bad for me. Rough, but never bad.

On a scale of 1 to 7, a microdoses should be in sub-0.5 range, if even that. (Josie Kins and her sister(?) have done an extremely good job of classifying the psychedelic experience as "levels": https://youtu.be/UQRfTD6AXPs?si=sfJc3pSYIvYBOVG6)
