I have been working with Peak Serum for about one year and half and I have been extremely impressed. Their customer service is the best. I get a response to my email immediately and all my questions get answered clearly. When I order products, I get them in lab at a time that is convenient for me (and usually hand delivered! AWESOME!). The performance of my HepG2 cells with US Origin FBS (PS-FB1) compared to other competitor’s products can’t beat. And what a great deal on their prices!
