wish i was in the UK to of been able to help out here...i only experienced mxe for the first time this past weekend and i loved it. i've only experienced actual K about 3 times and all of those times were about 10 years ago. i liked it ok but im pretty sure i actually liked this mxe stuff better. sucks for me because im in the US and i dont think its that easy to find some of these research chemicals here...and from what i've read there is a good chance of getting ripped off a few times before finding a good retailer if trying to order online...oh well, maybe i'll get the nerve to try and order some one day
