My lab recently ordered 10 bottles FBS from SeraPrima with a good price. Tom, the sales & operations manager, was very helpful and patient in communicating during the ordering process because our school needed to set up SeraPrima as a new vender. Tom did a great job to help us to complete the deal.

"I had a fantastic experience working with Tom Kutrubes, the operations manager. The samples he provided yielded excellent results, and the pricing was very reasonable. I’m excited to work with him again in the future!"

Working with SeraPrime for our serum (FBS) needs has been a fantastic experience. Very knowledgeable sales reps who went above and beyond to answer any questions and provide us samples. Ordering was seamless and product arrived in great time. Would absolutely recommend this company!

Very excited to start working with SeraPrime as our FBS supplier-- the quality is excellent and working with them has been nothing short of pleasant. Their communication is straightforward and they're always ready to assist in making things easier. Shoutout to Tom for all of his help!

Awesome experience working with SeraPrime! Cost-effective compared to other vendors, excellent product quality, highly responsive team and quick receipt of FBS! Will stick with this company for FBS needs.
