Where do you even get them? How do you know how much to take? How do you take them? I’ve tried finding centers to go to where they assist you but can’t seem to find any that aid with it end-to-end.
Technically you can’t get spores delivered to CA. Shipping to a friend in another state is not super hard.
Unfortunately, if you don't want to try and grow them you'll have to get them from someone you know. You could also try the dark web if you really want some, I'm sure you could get some there but if you can avoid that, it would be better. Fortunately it seems like getting mushrooms mixed with fentanyl isn't a thing AFAIK.

Up until recently, I was just eating a small amount - kind of hoping a stem and a small cap would do the trick. Most the times, this would work, but every once in awhile you'll get a small guy that is way more powerful than you think. I've found the best way for me now is to grind them into a powder and fill large fillable capsules with them. You can get several different sizes; I would start with smaller ones at first. The trick is to grind up as much of that batch of mushrooms as possible, as well as you can (I just use a simple coffee bean grinder). This does a good job of making sure each capsule you fill with the resulting powder is as evenly spread as it can be without special equipment. The benefit of this is you will now have 10-30 mushroom capsules with the same efficacy and you can then start with a single one and see how you feel. For your first time, I would not push past a single one. It can also sometimes take up to 3 hours before it really sinks in depending on what you're eating and such, so the first time just do not take another one.
Wish I could tell you where to get them, for me it was 'work in a restaurant'.
They won’t necessarily guide you through the set and setting.
The thing I recommend is to plan a date with yourself. Imagine the time and place you’d like to be in when you get a glimpse of the infinite.
You may wish to go with someone experienced for your first time, or even start with non-hallucinogenic dose and work your way up. (1/4 a hallucinogenic dose causes a barely noticeable pleasant feeling)
