30ML Master Isolate Vials — Frequently Asked Questions

What is a 30ml master isolate vial?

A 30ml master isolate vial is a large-format mushroom isolate—roughly three times the solution of a standard 10cc syringe—containing stabilized, single-phenotype genetics in a sterile solution. It's comparable to a mushroom liquid culture in consistency and convenience, prepared in an ISO-7 cleanroom, tested at zero psilocybin and psilocin, and ready to use for microscopy and taxonomy study. It's the high-volume version of our Isolated Spore Syringes.

Is a master isolate vial the same as a liquid culture?

A master isolate vial is the closest thing we offer to a liquid culture: stabilized, single-phenotype genetics suspended in a sterile solution, in a larger, ready-to-use format than a spore syringe. The defining difference is that our isolate vials are formulated and tested to contain zero psilocybin and psilocin, so they stay strictly within microscopy and taxonomy use. If you've shopped for a mushroom liquid culture, this is the equivalent in consistency and convenience.

Do you offer magic mushroom liquid cultures?

Our 30ml Master Isolate Vials are the closest product to what's often searched as a magic mushroom liquid culture—stabilized cubensis and exotic Psilocybe genetics in a sterile solution, in strains like Golden Teacher, Penis Envy, and Albino Penis Envy. The key distinction: every vial is formulated and tested to contain zero psilocybin and psilocin, and is sold strictly for microscopy and taxonomy study.

Spore syringe vs. liquid culture vs. master isolate vial: what's the difference?

A spore syringe holds 10cc of spores in a sterile solution, while a liquid culture holds stabilized genetics in a nutrient solution. A 30ml master isolate vial gives you that liquid-culture-style consistency at roughly three syringe-equivalents—formulated and tested to contain zero psilocybin and psilocin for microscopy and taxonomy. In short, the vial is the high-volume, refined, ready-to-use format.

How much is in a 30ml master isolate vial?

Each 30ml master isolate vial contains roughly three times the solution of a standard 10cc syringe—about three syringe-equivalents. That extra volume lets researchers run multiple microscopy sessions, repeated slide preparations, and longer-term taxonomic study from a single vial, which is why it's popular for extended or replicate research projects.

How do you store a master isolate vial, and how long does it last?

For best clarity under the microscope, use a master isolate vial within about 90 days. Stored sealed and refrigerated (36–46°F) away from light, it may remain stable for 12 months or longer. Use the included sterile syringe and needle for clean transfers, and discard the solution if it ever looks cloudy or discolored.

Do master isolate vials contain psilocybin, and are they legal?

Our master isolate vials are formulated and tested to contain zero psilocybin and psilocin, so they carry none of the controlled compounds and are sold for microscopy and taxonomy study. Legal status varies by location, so customers should follow their local laws. Spore Genetics ships worldwide and throughout the U.S., except to Georgia and Idaho.

What strains are available as master isolate vials?

Master isolate vials are available in popular cubensis genetics like Golden Teacher, Albino Penis Envy (APE), Penis Envy, and MVP, plus specialty species such as Panaeolus cyanescens and exotic Psilocybe azurescens, caerulescens, and niveotropicalis. Choose any three vials for automatic bundle savings, and check back as new stabilized isolates rotate in.

All Psilocybe products sold by Spore Genetics are intended for microscopy and taxonomy purposes only—not for cultivation or consumption. You must be 18 or older to order. We ship worldwide and throughout the United States except Georgia and Idaho; customers are responsible for complying with the laws of their own state or country.
