MRRL (Melmak Revert Revert) is a rare Psilocybe cubensis isolate derived from the Melmak lineage, a well-known branch of the Penis Envy family. Valued by microscopy enthusiasts for its distinctive morphology and unique genetic background, MRRL has become a sought-after variety for taxonomic study and spore research. Each Premium Spores MRRL isolate syringe is prepared in a sterile laboratory environment and contains a carefully selected genetic lineage for consistent microscopic observation.

About Our Isolated MRRL Mushroom Spores

MRRL Mushrooms are a unique Psilocybe cubensis isolate believed to originate from the Melmak lineage, a well-known branch of the Penis Envy family. Often referred to as Melmak Revert Revert, MRRL, Melmak Revert, Homestead PE, or occasionally Silvertip Mak, this rare isolate has gained attention among microscopy enthusiasts for its distinctive morphology and unusually large fruiting characteristics.

Under microscopic observation, MRRL spores display the dark purple-brown coloration typical of Psilocybe cubensis varieties. Researchers studying the Melmak and Penis Envy family lineages often find MRRL particularly interesting due to its apparent reverted traits, which produce more traditional mushroom structures while retaining many of the unique visual characteristics associated with the Melmak family.

MRRL specimens are commonly recognized by their thick stems, broad caps, unusual proportions, and distinctive appearance. These characteristics have made the variety increasingly popular among collectors and researchers interested in documenting the diversity found within the broader Melmak and Penis Envy genetic family.

What Are Isolated Spores?

Unlike multi-spore (MS) syringes, which contain thousands of genetically diverse spores, isolate (ISO) syringes originate from a single selected lineage. This often results in more consistent and uniform microscopy characteristics. Researchers prioritizing consistency can explore our Isolated Spore Syringes collection to browse additional isolated selections.

What’s Included With Your Isolated MRRL Spore Syringe:

  • One 10cc BD Luer-Lock syringe filled with contamination-free Isolated MRRL Mushroom Spores
  • One sterile 16-gauge needle per syringe
  • One alcohol prep pad
  • One hydrated spore microscopy instruction sheet

All Isolated MRRL mushroom spore syringes are produced in our state-of-the-art cleanroom laboratory and undergo rigorous quality testing prior to shipment to ensure sterility and reliability for microscopy research.
