Laboratory grade mushrooms are a frequently used term for referring to very good quality mushrooms, which can be studied under laboratory conditions. Although many people may be tempted to consider it a marketing phrase, it certainly stands for more than that.
Lab grade mushrooms are free from contaminating substances. Mushrooms are very sensitive to impurities from the outside environment. And lab grade mushrooms are grown from the purest type of spores. The best place to buy mushroom spores cost effectively is from Shaman Mushroom Spores.
In order to be able to do research on lab grad mushrooms, you need a license from the Drug Enforcement Administration. The requirements may vary from state to state. For example, in Idaho and Georgia it is illegal to sell and transport magic mushrooms, whereas in California, you are allowed to sell and buy mushroom spores, but only for scientific research purposes.
They are typically presented in the form of a spore syringe, and are obtained in special laboratories, in the most sterile conditions possible. The research is best made in a microscopy media room.
If you have a lab at home, you should definitely invest in a device for sterilizing equipment, such as a pressure cooker. This way you can make sure syringes are always perfectly clean and free from contamination.
