Researcher feedback

See why researchers choose Synthro for their critical work.
I've been ordering from this supplier for about six months. Purity is consistently above 99% on the COA, and it dissolves cleanly every time. Shipping is fast too.
Switched over from my old vendor on a whim and the per-vial cost was noticeably lower for the same compounds. Hard to go back.
Asked a detailed question about a batch and got a real answer quickly, COA pulled and all. That's not normal in this space.
