Psilocybe Cubensis Z-Strain

The z strain is one of the best commercially available strains today, for any skill level. This strain is one of the most aggressive producers, as observed in the wild. The mushrooms are dense, meaty, and large. Z-strain is not a slacker in any regards, and the clusters are numerous, with very few, if any, aborts. It utilizes its substrate to the max. They can also be very large mushrooms, towering over most other strains. Potency is also extreme from the reviews we have received from people who used them legally, that we interviewed.

Z-strain is a must have for any serious spore collector.

This strain was not found in the wild, like many other psychedelic mushroom spores that we sell. It was engineered in a lab, isolated from an unknown wild type that had amazing production capabilities, and large size. Over time it was further isolated into this beast of a cubensis strain.

Please be aware of our policy: Our magic mushroom spores that we sell are for microscopy or collection research use only. All images and information are provided for educational purposes and originate from labs outside of the United States. Source of spores does not grow any mushrooms, and we do not provide cultivation information, please do not ask. If we suspect that you may abuse our products, we will deny all purchasing privileges that you have.

    Syringe arrives in discrete package and is completely full of spores! I have gotten one from another site and they claimed you couldn’t see spores because they are “invisible” I’ve learned that that is just not true and lie to give you a less effective product. All seems sterile and packaged properly. Now we just have to wait for results 🙂

    First attempt, great show! Order from here, and here only, not only because of the high quality of the the visible spores (yes you can see them, like tiny clumps of sand floating), but honest policy on records. They simply keep them as short a time as possible! Keep your data safe! S.O.S. Is and will be my only place to round out my collection! Fast shipping, and good packaging. Thanks again, great product, and honest business.
