What we are not...

Blue Stem Spores does not promote the cultivation or consumption of psilocybin mushrooms, as psilocybin is currently a Schedule I drug under federal law. We do not sell spores to anyone under 18, nor send spores to CA, GA, or ID, where possession of psilocybin spores is illegal.


It is your responsibility to learn about and abide by local, state, and federal regulations with respect to mushroom spores. Currently, the sale and possession of spores is legal because these mushroom components do not contain the active ingredients of psilocybin, psilocin, or baeocystin. All Psilocybe Cubensis spores sold on our website are intended for microscopy and taxonomy purposes only. When contacting us please do not ask us about the cultivation of any mushroom species. We do not ship orders to California, Idaho, or Georgia, since possession of psilocybin spores is illegal in these states. We reserve the right to refuse sale for any reason. Refunds are offered upon request for products that fail to meet your expectations. 

Fulfilling all your microscopy needs.
