yea i understand the temptation to keep going, even 30mg is sacred enough to make it worth spending hours extracting

my last extraction got to that point, but when i went for another pull i got about 5-10 1mm crystals hahah so i knew that was enough

i just threw the crystals back in the solvent to help saturate it for my next run.
the differences between the forms/colours are minimal, it seems to be mostly placebo. there is a good amount of research done by people now that seems to be suggesting that is the case, but our experiences are our experiences and the placebo effect can be very real in its own way.
your situation sounds exactly like mine

about 3 months ago i joined here with the exact same story, i was sick of paying crazy prices for it. i use it for therapy as well as recreation so i was spending far too much.
i started to really enjoy the chemistry side of things before i even started my first extraction and i swear i had a huge smile on my face for the whole ~8 hours it took me to do it
since then i have looked into other potential, similar chemistry journeys to take my curiosity to the next level. i have not actually done anything else yet due to money limits, but next up is either a caffeine extraction or GHB. not because i can use any of those (not interested in either), but because they seem like logical next steps.
i also want to slowly build my stock of proper lab equipment and use that for simple things like DMT extractions so i can get used to using it and refine my techniques.
it really is a very exciting topic, i just wish i noticed that when i was in school!
good luck on your path. there are some VERY knowledgeable chemistry enthusiasts and professionals here and all have been very friendly to me so far (this forum seems to filter out the trolls and time wasters pretty well), so i am sure you will find this place to be useful for pushing your knowledge further. it can be a little slow to get responses, but the quality vs quantity is top notch here compared to any other forum i have been a member of.
