You're right, 7 will work much better.

On a more serious note, look into 4-AcO-DMT. Essentially mushrooms without the unpleasantness of actually having to eat mushrooms.

How does one even get access to this?

Perhaps easier than the mushrooms, various "chemical supply companies" will sell it to you for "research" and not ask many question. There's a list of such companies on the "RCSources" subreddit wiki.

It's definitely a good idea to get any chemicals tested before consuming them. I doubt they'd intentionally send you the wrong chemical, but I guess shipping mixups could happen. Energy control runs an excellent testing service https://energycontrol-international.org/drug-testing-service...

I'd try to Google a darknet Amazon.
