It provides pretty much the best euphoria I've ever felt its first few uses, and yes I've done pure MDMA, plenty of opiates and Cocaine/Speed before so its not like I don't have benchmarks to compare. Trippy edge to the euphoria too. Worth it though? Probably not, as euphoria is not too great after about 5 or 6 sessions and it is fucking addictive that you keep coming back once a week hoping you've got enough Serotonin/Dopamine stored up and alas, you never do...

Plus, there seems to be loads of acute and possibly long term nasty side effects. Worth it seems totally subjective though, even after abusing it like I have it all still seems 'worth it', I had a good summer, lots of fucked up nights and I'm still alive with only the slightest vasoconstriction coming up on the last time I did it ('cold' hands and feet, feet were a bit pale, hands a bit red) and some very sporadic heart pains that seem to be getting much better with exercise and lack of Mephedrone/stimulants. So it was worth it, for me, it may not be for you because you may lose a hand or something if this is such severe vasoconstriction occurring in some people.
