There’s a new trend in supplement certifications: the “secret shopper.”

They buy one tub a year off a website and claim it prevents brands from “cherry-picking” perfect samples.

Here’s the reality of cGMP manufacturing: when you run 1,000kg of powder through a commercial V-blender, it is entirely homogenized. There is no “golden scoop.” If the batch is contaminated, the whole vat fails.

Testing one tub annually is a PR snapshot that leaves 95% of a brand’s production unverified.

At LabTested, we don’t do annual stunts. We build neutral infrastructure so brands can publish their existing, batch-by-batch lab results right on the product page.

Prove every batch.
