Psilocybe cubensis var “Z-Strain” is a variety originally sold by a vendor known as Kreeper. There is some controversy over the origins of this variety as Keeper was known to order spores from other vendors (like Hawkeye) and rebrand them. Regardless, Z-Strain has stood the test of time and has beautiful spores worthy of your precious time under the microscope. A staple and much loved variety by beginners and advanced microscopists alike.

Abundant spores

The spore syringes contain many visible spores and are just perfect! Customer service is top-notch. I used Venmo to place my order, and the process is easy.

There were so many spores under the scope! HOLY COW I have never seen such a spore packed syringe! My favorite vendor never fails to impress me!

Very nice, thick patches of spores visible to the naked eye

Very good spore syringe, spores are in thick clumps visible to the naked eye. Tracking information received before it was sent so I could sell when it was arriving to keep it out of the winter weather. Cash order and received an extra freebie again, thanks.

Amazing Vendor

Absolutely love the customer service MMM offers!
Conveniently this was my first vendor to order spores from and was surprised how easy it is to find what you’re looking for, I’ve only ordered once but based off of my personal experience and the reviews of others I will definitely be back and this vendor will always be my go to. They are very communicative and respond pretty quickly and are ALWAYS trying to provide the best experience possible which I love. Shipping time is also great. As far as the product, I was very pleased. It was exactly what I ordered PLUS some goodies (can’t go wrong with mushroom stickers imo :)) overall just a great experience all around and again, will always be my go to vendor.
Also forgot to mention the verity of products! I often catch myself just scrolling through the catalog trying to see what I might want to get next!

Thank you for your service MMM, Mush love!
