SWIM has done a lot of meditation, research, and smoking (mary jane ) and believes he is ready for the DMT experience to open himself up to life.

First off, where can one purchase the necessaries? Such as MHRB? For a reasonable price of course, that is legit as well. SWIM has also heard that you can use substitutes to extract DMT. Is this true? If so, which ones, and where can I purchase those? (acacia confusa, etc.)

Also, what are some good teks to use to extract DMT? Preferably one that doesn't take much materials. I can't go out and get many chemicals. Hoping to find one that uses water, and not much else.

Lastly, please share your experiences. SWIM thinks this will be good for his spirituality and help shape his life.

Thank you for your help

Sourcing talk is not allowed on this forum, we don't want to draw any negative attention to vendors. You'll have to find them on your own, sorry.
All the teks can be found in other sections of the site, https://wiki.dmt-nexus.me/FAQ#DMT_Extraction.
Also, there is an entire section dedicated to experience posts, you'll find many quality ones there.

Sorry I couldn't be of more use, but all of this is available with a little looking around/using the search function.

Hope you find what you're looking for, and welcome.
