• Every new batch gets a report from an outside lab. We use Vanguard Laboratory (Washington), Eagle Analytical (Texas) and Ethos Analytics (Arizona). Every result we publish is that lab's, not ours.
• Some Vanguard reports are also on the lab’s own website. Those show a “Verify online” link.
• Vanguard is behind on uploading, so a newer batch may not be online yet.
• Vanguard will check any of our reports for you: call (360) 967-7010 or email [email protected].
• To match a report to your vial or bottle: the batch number on the label should be the same as on the certificate.

• Each line is one test the lab ran on this batch, with the method the lab used.
• Identity: is it the right compound? Checked by HPLC-UV/VIS against a reference standard.
• Purity: how clean is it? HPLC-UV/VIS.
• Assay: how much peptide is in each vial or capsule. HPLC-UV/VIS.
• Between units: do the units match each other? The limit is 10% for vials and 15% for capsules (USP <905>).
• Content vs certificate: does the measured amount match the amount stated on the certificate? USP monographs allow 90–110% of the label for vials and capsules alike.
• Adulterant screen: anything in the vial that should not be there. HPLC-UV/VIS.
• Heavy metals: arsenic, cadmium, lead, mercury and chromium. ICP-MS, limits per USP <232>.
• Endotoxins: bacterial toxins. LAL test, USP <85>.
• Residual solvents: leftover solvents from making the peptide. GC-MS, USP <467>.
• TFA: leftover trifluoroacetic acid. Ion chromatography, USP <503.1>.
• Container closure: is the vial sealed? Dye ingress, USP <1207>.
• Solubility: does it dissolve in water? Checked by eye.
• Sterility: no germs. The USP <71> growth test, and on newer batches the ScanRDI rapid method as well.
• Conformity: the lab’s quality team signs off that everything agrees.
• PASS means the result met the limit for that test. “Not on this report” means the lab did not run that test on this batch.
• Earlier batches were tested to our earlier standard, so some rows on their certificates say “Not on this report”. Newer batches are tested on the full 15-row panel; a row the lab has not reported yet also says “Not on this report” until it does.
• The number in brackets, like USP <71>, is the standard method the lab followed. It does not mean the product is a USP article.

• 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? Every certificate on this site shows how many tests that batch had: 15 for batches tested since August 2026, 7 to 14 for earlier ones. The certificate head says the number; the rows show which.

• Sterility means “no germs”. This batch was checked two different ways.
• Way one: Vanguard ran the USP <71> growth test. A sample goes into a broth, and the lab waits 14 days to see if anything grows.
• Way two: Eagle Analytical ran the ScanRDI rapid test. A machine stains and counts any living cells within hours instead of waiting for them to grow.
• Why two ways: the growth test finds germs that multiply in broth. The rapid test looks for living cells directly, including ones that grow slowly or not at all in broth. A batch has to pass both.
• Both results are on the certificate above.

• Since August 2026, every new lab has to pass the checks below before we rely on any of its reports.
• No ties to product sellers. We will not use a lab that is owned, in whole or in part, by a company that sells peptides.
• We look for labs whose main clients are laboratories and industrial businesses, not consumers.
• We require ISO/IEC 17025 accreditation: an outside body has checked the lab against the international standard for testing labs.
• That outside body must be a recognized one, such as A2LA, ANAB or PJLA.
• The test methods we use on peptides must be listed on the lab’s scope of accreditation: the public list of tests that lab is approved to run.
• Accreditation only for food or cannabis testing does not count.
• We ask labs to use USP test methods wherever one exists. USP (the United States Pharmacopeia) publishes standard test methods, so a test is run the same way in every lab and results can be compared.
• We require labs to run their testing under GMP or GLP: written procedures, calibrated instruments and a record of every test, so any result can be traced and checked later.

• Some sizes are tied to one batch. When yours is, that is the batch you get, and the certificate on this page is its lab report.
• If a size can come from more than one batch, the page shows the newest batch’s certificate and the heading says so. Yours may be a different batch.
• The batch number is printed on your product label. When your order arrives, check it against the certificate.
• If the batch on your label does not match the certificate shown here, tell us: free replacement.

• The size is how much we order, for example 30 mg.
• The lab measures the peptide in the vial by HPLC against a reference standard (no scale involved). It can be a little over or under, for example 34.08 mg.
• We always show you the real number, never rounded.

• Vials ship at room temperature. No ice pack is needed.
• Each vial is bubble-wrapped inside a padded mailer.
• When it arrives, store it the way the label says.

• “Label created” means the carrier has not scanned the box yet.
• It usually updates after the first scan.
• If it does not move, read the full article or ask us in chat.

• Not every vial has a strong vacuum. Some are sealed under low pressure, some with nitrogen gas.
• A weak or missing vacuum is not a defect by itself.
• The seal is tested on every new batch (container closure). On an earlier batch the certificate shows whether that test ran.
• If the seal is torn or lifted, see the return policy.

• Most peptide sellers publish two or three tests per batch. We publish 15 tests on every new batch, on 23 units, run by several methods (HPLC, ICP-MS, GC-MS, LAL and others), including net peptide content: how much peptide is really in each vial. Earlier batches were tested to our earlier standard, 7 to 14 tests, and every certificate shows which.
• Our quality team, Nichole and Torie, are trained scientists: former analytical chemists and QC/QA managers. They hold every new batch in quarantine until it passes our testing, and reject it if it fails.
• Outside, ISO 17025-accredited labs test each batch. On 3 in 4 batches two labs are involved: one for chemistry, one for sterility.
• Every result we publish is that lab's, not ours. We only use established labs that pass our onboarding checks.
• The lab report is on this page and behind the QR code on the label. Where the lab has posted it, you can verify it on the lab’s own site. The lab will also confirm any report by phone or email.
• Orders placed by 2:30 PM Arizona time (MST) on weekdays, excluding US holidays, ship the same day from Scottsdale, AZ.
• Unopened product can be returned within 60 days. A damaged or wrong item is replaced free or refunded in full.
• Earlier batches stay on the page, so you can see how each batch tested over time.
