Mushroom spore syringes and other accessories can be a good idea if you are interested in doing research and own a microscope. Spore syringes are available online here https://shamanmushroomspores.com, but they should only be used for scientific purposes.
Because they are made from mushroom bodies, mushroom spores are still prone to contamination. But if you take all the necessary precautions and use them in a sterile environment, in a fully-equipped laboratory, chances are you will not have any kind of problems and you can safely use them to study them under the microscope.
Spore syringes should not be mistaken for liquid culture, which is something entirely different. In fact, liquid culture refers to the exact results of a mycelium culture which was grown and further expanded in sugar broth. Unlike spore syringes, which are used for scientific research, liquid culture is used for inoculating different substrates with them and, therefore, for mushroom cultivation.
The good thing about mushroom spore syringes is that they usually do not contain any genetically-modified organisms. They should be stored under the conditions indicated on the package and should be used within the first year after they were purchased in order to prevent any unwanted surprises.
