Studying magic mushrooms is not easy because they contain an illegal, hallucinogenic substance. Therefore, you must be careful about the legal aspects of your state. However, considering that spores do not contain psilocybin (which only forms in the mycelium and fruiting shrooms), they typically can be purchased in most USA, as long as they are used for study and research.
It might seem like a loophole in the law that penalizes the sale, transport, and possession of magical mushrooms. Still, the easy access of the researchers to the spores may turn out to be beneficial, considering that more and more studies reveal different advantages of medical microdosing of psilocybin in treating different medical conditions.
Spore syringes can help you get the results you want, as long as you buy mushroom spores from reliable sources, store them safely and use them according to the instructions. That`s because mushroom spores can get contaminated easily, in which case they expire and are no longer helpful. Syringes are sterile and contain spores stored in a liquid environment that keeps them fresh. They should be stored in a refrigerator and typically used within 30 days, although this is a general recommendation; in certain conditions, spores have been reported viable even for up to one year!
