Comparable amounts im sure, but kev does seem to have a very dedicated European fanbase.
It seems like every pro has a supplement or clothing line that is selling very well "in Europe". Is this true? Or do they claim that because they know it will be impossible to disprove? If they claimed to have large sales in the USA, would those figures be easier to extrapolate from purchase reports from GNC and other supplement companies that are made publicly available or something like that?
