What researchers are saying.
“The COA arrived before the package. HPLC matched the spec to the third decimal. That alone earned my next three orders.”
Dr. M. Hartwell
Independent research consultant
“We switched our entire vivarium pipeline to VESPER. Same-day dispatch, no batch failures in 18 months. The closest thing to a pharmaceutical supplier I have used at this price point.”
K. Reyes, Ph.D.
Translational neuroscience lab
“Most suppliers give you a number on a website. VESPER gives you a chromatogram, a mass spec trace, and a sealed nitrogen vial. The difference is obvious from the moment you open the box.”
S. Tanaka
Senior research associate
