Live data — every record is aggregated from real public sources. VialGrade never sells; it links out to the vendor.
VialGrade

Vendor directory

Rank every vendor by what you care about.

Most reliable, cheapest, purest, most-tested, best-reviewed — sorted from real evidence, not marketing. A shady seller can spin up a new site overnight; we keep the record so a fresh coat of paint can’t hide it.

What matters most to you?

“Which one won't scam me?”

Independently tested, no enforcement flags, and a real track record — the safe default if you're new to this.

New to this? Three rules: a vendor should show a batch-matched third-party lab certificate (not their own claim); a price far below everyone else is a warning, not a deal; and these are sold research-use-only — no pharmacist or clinician stands behind them. Rankings use verifiable facts only, never who a product is “for.”
