What is B+?
B+ is a Psilocybe cubensis isolation and, alongside Golden Teacher, the default beginner strain. Its peer-reviewed psilocybin measurement (11.1 mg/g) runs higher than its Psilocybin Cup 'combined-tryptamine' community average (~6 mg/g) — the two come from different labs and methods, a good example of why we store and attribute both rather than pick one 'true' number.
Potency — measured vs. reported
Lab-measured: 11.1 ± 2.5 mg/g psilocybin.
Reliable lab data exists for only a handful of strains. We separate lab-measured values from community claims and don't inflate — growing conditions affect potency more than the strain name.
