We are one of the best research chemical vendors. We have an excellent selection of Gas chromatography-mass spectroscopy (GC/MS) reference samples along with a range of chemicals intended for laboratory research purposes. It should be noted that all products here (including mephedrone, MDPV and methylone) are not sold for human consumption and are not sold for use in any form of in vivo research or experimentation. We can cater for any project size, large or small... mephedrone, methylone and MDPV are available in bulk / wholesale quantities, as well as quantities suitable for small research projects..
