Buyer guide

TB-500 supplier pages should not make the buyer hunt for evidence.

The strongest TB-500 pages make the strength, batch, testing, dispatch route, and support process visible. Thin pages force the buyer to trust design instead of proof.

What to check

Confirm whether the page is for standalone TB-500 or a stack.
Match the vial batch to the COA batch.
Check whether the supplier explains storage and dispatch.
Look for a human support route before payment.
Compare with vendors that publish batch-linked product records.

The fastest safe path is still the same: batch, COA, label, payment, support, and dispatch proof before trust.
