Spore syringe cubensis Penis Envy Uncut Revert

Penis Envy Uncut Revert — often abbreviated as PEUR — is a spore-fertile revert of the famously potent Penis Envy Uncut (PEU) lineage. isolated by an anonymous cultivator in the mid-to-late 2010s and stabilised across multiple generations to make this PE-family genetic line accessible as a spore syringe.

Caps are moderate-sized, golden-brown to tan and convex-to-umbonate; veils are functional (unlike the parent PEU, which rarely opens). Stems are thick and meaty, with strong blue bruising — a hallmark of the PE lineage.

What you get

• 1x 10cc PEUR spore solution in a sterile 10ml syringe
• 1x sterile needle
• 2x alcohol prep wipes

Quick stats

• Species: Psilocybe cubensis
• Lineage: Amazon cubensis → PE (Rich Gee, c. 1975–1987) → PE Uncut (Workman, mid-2000s) → revert
• Colonisation: 24–27°C
• Fruiting: 21–24°C
• Volume: 10cc

Growing notes

Colonisation runs at 24–27°C; fruit at 21–24°C with high humidity (90–95% RH) and steady fresh-air exchange. PE-family and high-potency strains in particular reward patience — don't rush to fruiting conditions, and keep sterile technique tight to limit contamination during the longer colonisation window.

How to use: Flame-sterilise the needle, inoculate your sterile substrate or liquid-culture jar through a self-healing port, then store unused syringes upright in a clean dark place.

Storage: 2–8°C in a sealed bag protects spore viability; do not freeze. Use within 6–12 months for best results.

Potency note: PE-lineage strains are generally reported as above-average potency. No PEUR-specific lab data is publicly available.
