Magic Mushroom Spore Syringe - Mckennaii psilocybe cubensis

The Mckennaii cubensis spores are named after the famous psychonaut and researcher Terrence McKennaii. The exact origin form this strain is unknown. The Mckennaii grows wild hand-shaped mycelium knots, with lots of medium sizes mushrooms. Caps are brown and can grow small or wide. The Mckennaii is a highly potent mushroom when grown in the right conditions.

The spores are available in vials and syringes.

Product Description

Mckennaii 20cc magic mushroom spore syringes are produced under sterile conditions and should be kept dark and refrigerated (2-8°C) to increase the shelf life of the cubensis spores.


  • 1x 20cc Mckennaii spore solution in a 20ml syringe
  • 1x sterile needle
  • 4x Alco prep


Special Solution

The Mckennaii cubensis spores are dissolved in a specially developed organic solution to promote the quality of the spores.

Compared to water based spore solutions;  you will get larger yields, stronger mycelium and faster colonization because of this special spore solution.

Why these syringes are better than other spore syringes

  • Spores are 100% free from contaminants and they are very contaminant resistant after leaving the syringe.
  • Improved shelf life. Over 6 months longer; now 18 months.
  • Spores are not sticking to sides of the syringes anymore, thus easier to handle and more grow parts per milliliter (500 gpp ml).
  • Contains nutrients to 'kickstart' the spores when inoculating.
  • Solution boosts strength of mycelium.
  • Faster colonization of substrate and cakes.


How to use the Mckennaii spore syringe

The Mckennaii spore solution is held inside the syringe by a luer lock stopper on the end where the needle goes. With this luer lock stopper attached makes it easier to transport and to store the Mckennaii spore syringe.

Make sure to work as hygienic as possible. Wear a face mask and sterile gloves and/or disinfect your hands. Hold the Mckennaii spore syringe in front of you with the luer lock stopper pointing upwards. Remove the luer lock stopper by screwing it counter-clockwise. Take the needle out of the sterile package and screw it on the Mckennaii spore syringe. Shake the spore syringe vigorously for ten seconds before you remove the protective cap from the needle.

To proceed from here, there are several methods to choose from:

Dropping the spore solution onto the substrate

After having prepared your own substrate or cakes you can drop the Mckennaii spore solution directly from the syringe onto these. Press the plunger slowly so that drops of spore solution will come out of the needle. Every drop that will be in contact with the substrate will be a potential mycelium growth point, so spread out these drops all over the substrate to evenly colonize the substrate with mycelium.

How many cakes can you make with spore syringe?

One 20cc spore syringe can easily colonize 6 liters / 13 pints of substrate.

Injection through injection ports

This is almost identical as dropping the spore solution onto the substrate. Open the injection port by pulling back the port protection cap. Use a alco prep to sterilize the injection port entry. Pierce the opening with the needle. Now drop the spore solution evenly over the substrate inside the spawn bag or grow box. After the Mckennaii spore solution is injected, remove the syringe and close the injection port with the port protection cap.

Study spores and research using a microscope

Seen from a scientific point of view; all Psilocybe cubensis are alike. But they do differ slightly in appearance and fruiting speed (phenotype). There are numerous Psilocybe cubensis that have different phenotypes. These different cubensis are not considered subspecies, but different strains. The Mckennaii is a strain of Psilocybe cubensis.

The differences in phenotype can be seen with the naked eye, but the true beauty lies under the microscope. The wondrous world of the spores. Many of our customers are scientists or enthusiasts, doing research on these differences in a homemade laboratory. After having prepared your microscope slide, drop some of the Mckennaii spore solution on it. Cover the specimen with a microscope covering glass. The best magnification for Psilocybe cubensis and Panaeolus cyanescens spore research is a magnification of 1000x or higher.

Using liquid culture growth medium with the spore syringe

The special solution in which the Mckennaii cubensis spores are dissolved, kickstarts the growth of the mycelium. We do not recommend the use of liquid culture growth medium to get stronger mycelium. If you desire to produce liquid cultures, we recommend to choose for the professional Mckennaii spore vial rather than the Mckennaii spore syringe. If you want to experiment with this Mckennaii spore syringe and liquid culture growth media, we'd love to hear your feedback on your results.

How to store a spore syringe

The Mckennaii spore syringe should be stored refrigerated in a temperature between 2°C - 8°C or 35°F - 46°F. The shelf life of the spore syringe is at least 12 months after they leave our warehouse.

10 days without any signs see review Review by Marius
Not my first time doing this, using sterile room with flow hood, rye berries in 1pint mason jars. 10 days in and no action. Not to mention the syringes arrived with little to NO spores inside. Bought the same syringes from the competition and the syringes were unbelievably packed with spores. After 3 days jars were working.

I’ve contacted the staff via the chat to ask for a solution so I wouldn’t have to leave a negative comment but I was completely ignore. I’ve ordered before from this site, but now I promise this was the last time. Too bad you don’t respect your customers enough.

[MMS edit: Hi Marius, sorry to hear about your experience. We tried to contact you to find a solution, but our messages are likely getting to your SPAM folder in the email. If you read this, please check the SPAM and contact us by mail or phone.] (Posted on 3/15/2024)
Total shit Review by Samuel
I used a whole syringe to 7 kilos of substrate. None of the jars worked. Im an experienced grower and has always bought from here. But this time was a big no no..... very disappointed.

MMS customer support desk edit:

Please always contact the customer service desk when any issues arise. In this case, we would recommend using liquid culture because one syringe on 7 KG of the substrate is a lot of substrate. liquid culture will make the spawning a lot quicker and more efficient. (Posted on 8/18/2022)

I was absolutely impressed by the PES Amazonian syringe, this one sadly didn´t not colonized at all. Very sad about that :( (Posted on 8/29/2021)
everything's great Review by Natasha
Great shop, got my order fast, also quick customer service. Tried innoculating two jars... almost fully colonized and ready to start fruiting!! Can't wait :) (Posted on 7/30/2020)

great product Review by gareth
With Magic-mushroom-shop I get great a great product and great customer service, I don't shop anywhere else. This syringe is colonising WBS very nicely, looking forward to the fruits. (Posted on 12/16/2017)
