Methcathinone (also known as Ephedrone, Methcat, CAT) is a synthetic stimulant substance of the cathinone chemical class. It produces standard amphetamine-like stimulant effects. It is similar to the cathinone compounds found in the khat plant of eastern Africa and mephedrone in its structure and effects.

Methcathinone was first synthesised in 1928 in the USA and it was used in the Soviet Union as an antidepressant. It is common in central and eastern Europe, often sold as the more well known mephedrone or synthesized from OTC drugs containing ephedrine or pseudoephedrine.


Methcathinone is comprised of a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain containing a beta-ketone group (what is known as a cathinone molecule) with an additional methyl substitution at Rα. It can be thought of as the cathinone homolog of methamphetamine as it has the same general formula, differing only in the addition of a single double bonded oxygen.

Although the effects of methcathinone have not been formally studied on the same level as amphetamines, it is possible to speculate that like other simple substituted cathinone, it most likely acts primarily as a dopamine and norepinephrine reuptake inhibitor.[1] The result of this is an effective increase in the levels of the norepinephrine and dopamine neurotransmitters in the brain by binding to and partially blocking the transporter proteins that normally clear those monoamines from the synaptic cleft. This allows dopamine and norepinephrine to accumulate within the key area of the brain linked to reward and pleasure to extra-endogenous levels, resulting in stimulating, motivatory and euphoric effects.

How to Dose Properly

Methcathinone is amazing if used correctly. If you misuse it you will feel the compulsive need to redose mainly, and have a mostly negative experience. It has a short peak and then comedown. You need to eighter redose properly to extend it or to leave it alone for today. When you take a dosage of Methcathinone, per say 350mg, you have to redose 25 mins later as a 40-50% of the first dose. So you don't comedown.

Its really worth to redose once since actually it will be only a 45 min ride and the 4 hours comedown hell. Gradually decreasing the dose instead aka a redose will make it a ton more manageable. You can then redose another 40% or leave it. But don't redose more than twice.

What I recommend for the comedown is that 60mins after you redosed last to take 20% of the first dose. Then to stop. That's the best method to not have a huge comedown.

For a mild stimulating experience, take a light dose first, then redose with a medium dose, then as a final, a medium or medium-high dose. Space the doses out more.


Methcathinone is synthesised most easily by reacting Pseudoephedrine with KMnO4. The reaction is very specific though. A very specific temperature needs to be achieved, below zero, so that the oxidation is subtle and not too energetic, so that it does not destroy the Pseudoephedrine and make it into Benzaldehyde. The same goes for the amount of KMnO4, it has to be a specific ratio of oxidizer to Pseudoephedrine.
