4CMC is no longer manufactured, we recommend Euthylone instead.

4CMC, also called 4-ChloroMethCathinone, is a novel Research Chemical from the substituted cathinone family. It is a strong dopamine and serotonine releaser without acting as reuptake inhibitor. It comes in large transparent crystals.

Product description

Image from our product 4CMC-crystals which we make at our dedicated lab
4CMC, also known as Clephedrone, is a stimulant drug of the cathinone class that has been sold online as a designer drug.


In radioligand binding assays, 4-CMC had very low affinities of 9,410 nM, 28,700 nM, and 19,600 nM for the dopamine transporter (DAT), serotonin transporter (SERT), and norepinephrine transporter (NET), respectively. In uptake potency assays, 4-CMC had low uptake potencies of 208 nM, 670 nM, and 75.5nM for the DAT, SERT, and NET, respectively. 4-CMC possessed full efficacy at stimulating the release of dopamine. The maximal response elicited by 4-CMC was 83.5% of the efficacy of methamphetamine. The maximal response elicited by 4-CMC was 124% of the maximal efficacy of methamphetamine. 4-CMC was more potent (EC50value = 1,980 nM) at stimulating release of serotonin compared to methamphetamine (27,500 nM).


In mouse locomotor activity assays, treatment with 2.5 to 10 mg/kg 4-CMC i.p. resulted in time-and dose-dependent increases in locomotion. Peak locomotor effects were observed following 5 mg/kg 4-CMC. Maximal locomotor stimulant effects of 5 mg/kg 4-CMC occurred 10-40 min post injection and lasted 70-230 min. Compared to cocaine, methamphetamine, and MDMA, the maximal stimulant effectsof 4-CMC were 66%, 63% and 64%, respectively. In drug discrimination assays, 4-CMC i.p. fully substituted (ED50= 4.3mg/kg) for the discriminative stimulus effects of 10 mg/kg, i.p. cocaine in rats. 4-CMC also fully substituted (ED50= 3.9mg/kg) for the discriminative stimulus effects of 1.0mg/kg, i.p.(+)-methamphetamine.


We make 4CMC at our own lab. Crystals are trasparent and huge, see image below. It has a purity over 99%. Please store sealed. For long term storage keep at -20 degree. Durability is 7 years.

Product reviews

This is a pro and legit store of research chemicals, arrived very fast (2days), product is as described and have nice prices. Looking for making more and bigger bussines with JUKLIS LAB in a few weeks. Bulk prices are very goood.
Thank you!
Esta es una tienda profesional y legítima de 'research chemicals', llegó muy rápido (2días), el producto es como se describe y tiene buen precio. Haré mas y mayores negocios con JUKLIS LAB en un par de semanas. Los precios 'bulk' son muy buenos.
