    I would say that I enjoy 4-EMC moreso than Mephedrone. The effects profile being more favorable and expansive, the duration longer, the potency by weight a degree higher, and lacking characteristic feelings of Mephedrone-induced cardio- and neuro-toxicity.

    This is an Research Chemical that as far as I know is the closest related analogue to Mephedrone (4-MMC). It is simply Mephedrone with an extra carbon chain on the first methyl group. Hence the “ethyl” in the name.

    Bombing works best for me. 150-200mg followed by a 50-100mg booster 1.5 – 2 hours later. Total duration about 5 hours. Feels a bit like 3-MMC without the stimulation.

    This is a great website, I’ve been doing business with riomeds for a long time now, I always get 4-EMC from them because i trust it will be pure. One time the package did not arrive as it was supposed to and they resent it right away and came that time. I would def recommend.

    4-EMC is dubby, psychedelic entactogenic/empathogenic and aphrodisiac cathinone derivative that possesses strong euphoriant properties directly comparable to MD(M)A for me. 4/5 for this
