Panaeolus Cyanescens 'Goliath' Mushroom Spores

This panaeolus cyanescens deserves its strain name "Goliath" for clear reasons: The mushrooms grow tall and the hats are very broad and wide. The meaty flesh of the fruits makes that the potency is very high, also in the fresh weight. Just like other p. cyanescens, the Goliath prefers cow dung to grow, but horse manure also works very well. Also 'cubsensis' TEKS can work, but these will make the Goliath apear more as several 'Davids': Small and powerful.

Product Description

Panaeolus cyanescens 'Goliath' magic mushroom spore vials are produced under sterile conditions and should be kept dark and refrigerated (2-8°C) to increase the shelf life of the spores.

Vial vs. Syringes

Spore vials are superior to the spore syringes in most fields. Get the best results when cultivating Panaeolus cyanescens 'Goliath' magic mushrooms with this quality spore vial. Using spore vials will result in a higher success rate in the colonization and fruiting process.

Reasons to go Vial:

  • Longer shelf life than most spore syringes (2 years vs 6 months)
  • It's easier to get ALL spores out of the container. Plastic syringes are often charged with static electricity making the spores stick to them. Glass vials are not so 100% of the spores will come out.
  • Works great with liquid culture growth media. Syringes can be prepared with a different solution, rendering any liquid culture medium unusable.
  • Spore vial solution has over a 1000 grow parts per milliliter, versus 500 g.p.p. ml or even less in most syringes.
  • Professional look and feel
  • Takes up less space
  • Easier to transport



  • 1x Glass Vial with 10ml Panaeolus cyanescens 'Goliath' cubensis spore solution
  • 1x Sterile 10ml Syringe
  • 4x Alco Preps


Instructions to use a Panaeolus cyanescens 'Goliath' spore vial

The vials have a cap with a circular rubber membrane. The rubber membrane, or septa, can be pierced by the needle of a syringe, but will stop any airflow, micro organisms or anything else to go through by itself. 

Shake the Panaeolus cyanescens 'Goliath' spore vial vigorously to spread the spores evenly throughout the vial. Remove the protective stopper cap from the top of the vial and sterilize the septa with an alco prep. Unpack the sterile syringe and remove the protective cap from the needle. Insert the needle of the syringe through the septa.

The point of the needle should be submerged in the spore solution. Pull back the plunger of the syringe slowly so that the syringe will fill with spore solution. Just 3 milliliter of spore solution is needed to colonize 1 liter / 1.05 quart of substrate. After having filled the syringe with the required amount of spore solution, slowly take out the needle from the vial.

To proceed from here to the inoculation process, 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 Panaeolus cyanescens 'Goliath' 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.

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 Panaeolus cyanescens 'Goliath' spore solution is injected, remove the syringe and close the injection port with the port protection cap.

Liquid culture for faster colonization and stronger mycelium

When injecting the Panaeolus cyanescens 'Goliath' spore solution in a 'bath of nutrients', such as the Liquid Culture Growth Medium, the spores will form into mycelium inside this liquid suspension. This is called liquid culture or LC for short. Liquid Culture Growth Medium itself can be used to inoculate substrate and cakes. Liquid culture growth medium has a higher success rate and will be much more reliable than trying to germinate the spores without the use of  LC. In short: Using LCs will increase the chance on mushrooms.

Note: The Liquid Culture Growth Medium will not work well with our spore syringes.

Study spores and research using a microscope

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

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, doing research on these differences in a homemade laboratory. After having prepared your microscope slide, drop some of the Panaeolus cyanescens 'Goliath' spore solution on it. Cover the specimen with a microscope covering glass. The best magnification for Panaeolus cyanescens and Psilocybe cubensis spore research is a magnification of 1000x or higher.

The syringe and reusing it

After using the syringe to inoculate the substrate, cake, or LC  with Panaeolus cyanescens 'Goliath', you can reuse the empty syringe after you have sterilized the needle. This can be done with a spirit burner or lighter. Burn the needle by keeping it in the flame long enough to make it glow orange. Let it cool down before you insert the needle again. Instead of reusing one, you can also order a sterile needle separately.


Store the Panaeolus cyanescens 'Goliath' vial in the refrigerator between 2°C - 8°C or 35°F - 46°F. Leave the 'septa protecting stopper cap' in place when storing the vial. After removing this protective cap, always sterilize the septa with an alco prep before you insert the syringe.

Panaeolus cyanescens 'Goliath' spore vials can be stored this way for 2 year after leaving our warehouse.

No sign of life Review by Kurt
Innoculated about 30 plates. 1 week later nothing. No visible spores in solution. No removable cap on vial. (Posted on 8/28/2020)
very good Review by iorga
first harvest in about 3 weeks, around 60% of growing surface and the trip was strong intense ..worth the money and effort (Posted on 7/20/2018)
not happy Review by james
i bought this vial and was immediately alarmed at the lack of visible spores. although i know they are not always that visible. i shot up 4 bags of organic and professionally prepared rye berry's. out of the 4 only 1 half inoculated. i tried to contact the m.m.s and emailed them and have never had a reply. so i would not waste your time with them.

[email protected]: Sorry to hear the spores did not germinate. Please send us pictures of the vial and the production code and I will verify your problem with our spore supplier.

Hi James,

Thank you for your message.
What unfortunate to hear you are experiencing grow issues with your Goliath spores.
To understand more about your situation, please provide us with some more information such as;

-Which cultivation technique did you follow? :
-Please elaborate on how you prepared the substrate/jars and the ingredients used:
-Did you use agar/liquid culture? if so, how much spore solution did you use?:
-How much spore solution did you use to inoculate your substrate (and how much substrate did you try to inoculate)?:
-What are the provided grow conditions? (temperature, humidity level, cultivation spot etc etc):
-Did you shake the vial prior use?:

Please send us some clear pictures of your inoculated substrate/jars so we can have a look and show to our supplier and mycologist. (Posted on 12/23/2017)
