Psilocybin spores come from magic mushrooms. They grow the wild, but the substance they contain – psilocybin – is banned since the `70s, which makes purchasing, selling and consuming these mushrooms illegal. However, psilocybin spores have a different status, being in a gray legal area. That’s because they do not actually contain psilocybin yet (it only appears in later stages of development). So, spores can be legally used for the right purposes (research and identification).
However, if you want to avoid legal issues, you must choose your seller with great care. Make sure it has positive ratings and reviews, as this is pretty much the only indicator that you will get quality psilocybin spores that did not germinated yet and are not contaminated either.
You can easily find psilocybin spores online; a simple Google search will reveal lots of results, ranging from social media groups/ pages to online shops like the popular Sacred Mushrooms.
However, you should make sure that you purchase quality mushroom spore syringes, otherwise, you risk becoming the victim of fraudulent advertising, you will get compromised spores that may even bring you legal problems, and there may be no way to get your money back, considering that the psilocybin spore market is not regulated.
