How has your testing changed?

Every batch we sell has its own lab report from an outside lab. The report has grown over time. Here is how, with the dates from our own certificates.

February 2025. We started putting a lab report on every batch. One outside lab, seven rows: is it the right compound, is it clean, how much is inside, does that match the label, any germ dust, one germ test, and the lab's sign-off.

April 2025. Heavy metals added. Eight rows.

October 2025. Germs checked two ways, at two labs. Vanguard grows a sample for 14 days; Eagle Analytical counts living cells the same day. A batch has to pass both. Nine rows.

February 2026. The full panel. Four tests added: leftover cutting acid, leftover cleaning liquid, is the vial sealed tight, does it dissolve. Three vials measured for how much is inside, instead of one. Fourteen rows. Every new batch since June 2026.

August 2026. The adulterant screen: anything in the vial that should not be there. Fifteen rows on every new batch, on 23 units. Every new lab has to pass our onboarding checks first; Ethos Analytics joined in September.

Which standard is my batch?

Look at the certificate for your batch. New batches, tested since August 2026, carry all 15 tests. Earlier batches were tested to our earlier standard, 7 to 14 tests. The certificate head says the number; the rows show exactly which tests that batch had. Nothing is summarized away.

Where to find it: scan the QR code on your vial, or open the certificate from the product page or the Certificates library. If you cannot find the certificate for your batch, email hello@peptidology.co or call/text (480) 974-4660.
