MedChemExpress LLC Arvostelua 

Do NOT buy here!! They are scam. Made an order and they send me empty bag. I requested a refund and they kept making up excuses

Very fast delivery speed!

Very good quality to meet my experiment requirement.

Relabel products with cheaper price,

If you need a compound with a specific purity, DO NOT trust their CoA. After a few back and forth, they told me they don't do quantitative NMR and that the value reported on the CoA ">95%" was based on the visual inspection of the 1D NMR spectrum. This is not how Chemistry works...

The customer service is really good and always give quick response, the tech support team is quite patient and answered my questions very clearly. I think I will choose MCE again and I will recommand MCE to my teamates as well.

AVOID - This company makes substandard products and have no customer support. They will ruin your experiment due to poor product quality. Furthermore, you cannot plan things correctly because they are poor at completing documentation for customs, as such shipments are help up at customs creating major problems, delays and extra cost. Also their customer services dept disappears, so you are left to frantically attempt to resolve everything yourself

I often use protease inhibitor cocktail for my protein experiment from Roche but just discovered that MedChem has the similar one, cheaper, and got a similar result, so worth a try.

The inhibitor of PSTAT3 BP-1-102 order doesn't work at all.

Rude and ignorant customer service cancelled my order which had already been accepted and charged to my corporate credit card and business account, with our business name. I was told I was not a "real lab" and treated very badly. Within minutes I got my item from a competitor with no hassle at all. Medchemexpress discriminates against small businesses based not on facts but the ignorant opinion of some dim witted CSR. We are a licensed lab and a registered LLC with a non-residential delivery address. We get routine deliveries with no problems from Aldrich, NEB and ThermoFisher, etc.
Medchemexpress is poorly run and staffed by rude fools.

Order the 3 PI3K inhibitors directly online from Medchemexpress. Got the package delivered in 2 weeks and the origin was from Shanghai, China. HPLC results showed the purity of all 3 inhibitors were blow 95% but the website and datasheet claimed over 98%. I can not use them for my experiment. Waste of time, a piece of crap. Be cautious.

really good service, everything delivered as promised on time.

MCE is an Excellent company providing high-quality high purity products and fast shipping and strong customer support! We are extremely satisfied as a long term customer. A lot of their inhibitors are 10 times cheaper than a lot of other companies like selleckchem.
Their 1 g product (inhibitor for mice) has the same price as 100mg same product with other companies yet having higher purity. Sigma and Fisher and other big companies order from them and do resale for profit. If you buy from them directly, that will be much cheaper. They saved a lot of money for us. I know that the bad reviews left here are from their competitors. MCE is a great company with great potentials and fast development. They ship from NJ overnight to 2-3 days sometimes with free shipping.

The claimed chemical is not pure and correct.
Waste many days of work.
