Can DMT be IVed?
It can, but we do not recommend it mainly for two reasons:
1- The only official research done with DMT by Rick Strassmann used FDA-approved very pure DMT fumarate. The quality of home extraction products might be questionable, one may have solvent traces and other impurities that could be uncomfortable, painful or downright dangerous to inject.
2- The onset of the effects are so quick that one might not be able to take out the needle in time and accidentally ripping their vein out while in hyperspace, or putting it down too near and rolling around/puncturing oneself
If one still decides to do it, then please: Use food-safe/USP grade chemicals to extract, take care in making many purifying steps (several recrystallizations/washes) and making sure it has no solvent or other chemical traces in the final product (redissolving the recrystallized product in USP grade acetone or ethanol and re-evaporating, scrapping and letting it dry completely before converting to fumarates in a sterile solution, etc.).

Also, for the first try, take at most 0.2mg/kg, preferably less. And VERY importantly,
do NOT do it by yourself, have a sitter that is experienced with needles inject for you and be there to make sure you are physically safe.
