Penis Envy shrooms are the exact same as any other cubensis potency wise. PE costs the same for the spores and the same to grow because it is the same mushroom. What determines potency is not the "strain" which is purely a marketing technique but how the shrooms were grown. PE is simply a way for people to make more money off the same shrooms. If you were to search the internet for yourselves you would find out that you've been getting ripped off.
100% wrong. Responded in the other thread as well.
RR's statement is a 'cube is a cube, except for PE.'
I do not believe he created/isolated PE, I thought it was someone else and while it 'costs the same' to grow as far as grow media, they are more finicky, yeild less in the same time/space, are slower to colonize and don't fend off contams as well as other 'strains'. Time and Space = Money, so they do 'cost more' to produce.
