Research Sourcing

Every supplier has a certificate. Almost none of them can be checked.

Purity is the cheap test. Lab names are easy to paste. And a real report is worthless if it is about a different lot. Here is how to tell proof from paperwork in under a minute. Buy 1, Get 1 Free is live on AKRO Research now.

The breakdowns

Three things almost nobody checks before they order.

Testing standards

Purity is the cheap test. Here are the four your supplier probably skipped

Measured content, heavy metals, sterility, endotoxin. Four separate tests, and most listings answer none of them.

Lab verification

A certificate you cannot verify is just a PDF

Lab logos cost nothing to paste. The only certificate that counts carries a code the lab itself will confirm.

Lot traceability

The certificate was real. It just was not for your vial

A report covers one lot at one strength. Turn the vial around and check the lot number. Almost nobody does.

Documentation before you order, not after you ask.

AKRO Research links the original lab PDF for each published lot right on the product page, with the lab named and a code you can check with them.
