@jens Just Shungite I purchased off Amazon. It was not verified by any governing body or organization (to my knowledge).

@jens I have tested my shungite with an e-meter and it does seem to reduce localalized EMF acutely. However, the effect drops off within a small radius. I have to be holding the meter directly on or just over the shungite, and place the shungite directly in the path from the source to the meter.

Some favorites from my weightlifting playlist:
Volk an's Gewehr
Klendathu Drop
Botho Lukas Chor

I also like Nuclear Power Trio's 'Critical Bass Theory'
