What to check
- Ask for the exact batch or lot before paying.
- Check whether the COA names the same batch.
- Reject screenshots where the batch field, lab name, or test date is cropped.
- Save the product page before checkout so changes can be compared later.
- Prefer vendors that make batch records public without needing a private message.
The fastest safe path is still the same: batch, COA, label, payment, support, and dispatch proof before trust.
